NESTBOX MONITORING PROTOCOL ON THE TRAIL – LEARNING and EDUCATION TO OTHERS IS KEY ON THIS WEBSITE.


Recently, I have been active on various bluebird Facebook pages on monitoring the cavity nesting birds in the nesting boxes.  Here is a post I did today regarding when to stop opening the boxes when the nestlings inside are at a certain age:

I use Day 13 as my guide as last day. I use an auto-visor mirror always to hold at the top of the box to look down at the nest.  At 12 to 13 days old, I just crack open enough and use that mirror and stay diligently fast and efficient to check on their health, development, do the headcount, and look for a potential nestling death (if that happens, it is still a safe time to remove the dead one if at all possible–by this age, the percentage is low).  After Day 13, I do observations of activity at the boxes by the parent behaviors in surveillance method from afar–a great indicator how the kids are doing!  There is a time when human monitoring at the nests so close up has to cease for the fullest safety for all.  I do not want to open up the box when the nestlings are starting to get active inside as they move around, stretch their wings, exercise their legs…to gain strength for fledging….while getting the confidence that they can fly for the first time into the world they know nothing about!  Some fecal sacs are not picked up yet by the parents so  it’s not good to have any natural bird odors from the boxes get into the air circulations to attract predators (specifically the common black rat snakes here in the South that have keen smelling ability close or from a distance–they feed night or day).  This is another reason why I do not open the boxes every single day, which is a bit excessive as nestbox micro-management by humans, in my personal opinion.  I do not even approach too close to the boxes during fledging process dates between 16 and 19 days.   I use a chair or my car and some binoculars and watch the action of the parents going to the nestbox for feedings.   The anticipation then sets in and I use nature’s way with the awesome parent birds to take over without my interventions, if at all possible.  Average fledging age on my trail is Day 17, but sometimes it can be the 18th day.  Oldest age ever was 22 days due to a nest change for the nestling to recover from blowfly larvae infestations.  That was in 2008.

Bluebird Nesting Guide from Virginia Bluebird Society

With that, I also have cross posted this on those same Facebook pages.  It is not only fitting to share this on the topic, but imperative for educational purposes.  Here is that text:

I am cross posting at a few Facebook pages Cornell’s NestWatch monitoring protocol guidelines and principles of birding ethics, the Code of Conduct, in human monitoring all nests in the wild, including our nesting boxes.  The advice and guidelines are easy to read and is based on the American Birding Association’s birding ethics and protocol (find them at www.aba.org).   I participate and am certified in NestWatch.  It’s an excellent source of information!  If you haven’t yet, take some time to look around the NestWatch website.  While you’re there on the Code of Conduct page, look to the left and click on the links on Nest Monitoring Protocol and Nest Monitoring Manual and FAQS, which is great for new bluebirders to learn from.  Enjoy!
http://nestwatch.org/learn/how-to-nestwatch/code-of-conduct/

I also follow all state and federal laws on my 43-box bluebird trail and all other birding adventures in my locale (such as monitoring a Northern Mockingbird nest at my neighbor’s house), based on the Migratory Bird Treaty Act of 1918 ( in particular, I am referring how I handle native birds and non-native invasive species).    Here is that website from the U.S. Fish and Wildlife Service: https://www.fws.gov/birds/policies-and-regulations/laws-legislations/migratory-bird-treaty-act.php

Here is a recent photo of Mom Blue who did not flush off the nest during a box check.  I never force her off.   However, with my quick skill one-handed with my small digital camera with the box panel door cracked open so as not to startle her too much (I never use flash photography on live birds inside the boxes), I was able to capture her on her egg clutch.  The natural lighting also captured the brilliant blue feathers on this incubating female.

Here is a picture of a lone bluebird baby among 5 other unhatched eggs.  Though I do possess the appropriate state and federal permits to handle young and eggs, it also challenged me to safely handle the situation to remove the unhatched eggs that would and could have been devastating to this nestling for various reasons….the eggs could crack and break and get sticky embryo contents on the nest, thus getting on the nestlings feathers, legs, etc., and attracting predators….OR….possibly causing leg splay issues as the nestling continually gets cramped in growing sizes among the eggs, which could develop into a deformity and fledging problems.  Here is a picture — this bluebird nestling in 2014 was sitting on one of the unhatched eggs — no more room in that cup for the little one.  Age of the nestling is at 5 days old.  We don’t want it to grow any larger.  I have posted this before, in 2014.  Perhaps you recognize it?

"The Lone Child"

I very often go through my yearly photo journals on my computer to review the photos I’ve captured to remind me on what I’ve learned through the years helping the nesting birds while applying the code of ethics associated with human monitoring of nature’s nests.

Here is a recent photo I took of 13-day olds.  No more opening the box after the 13th day!

MID-NESTING SEASON REPORT – Date of Report is July 9, 2016


This is a a mid-season report I posted on the trail’s Facebook page.  I am duplicating it here, including an attached video of removing the unhatched egg from Nestbox #12 on July 9, 2016.  Only 1 of the two eggs hatched.  Unhatched eggs can be removed AFTER 72 hours from hatching of the remaining eggs in the nest.  

Four species using the boxes. Note: Still pending eggs, hatching, and fledging in the numbers indicated below for Bluebirds and House Wrens. This is as of trail check dated July 7 and two boxes were checked today, July 9, 2016. 3rd broods started thus far in 6 nestboxes. I expect a few more. Let’s say I am NOT happy with these results. The challenges have been astounding this year. Last year of 2015 was my best ever year in 10 years of the trail. This year 2016 is my worst ever. All the reason to continue to want to help these birds succeed. This is a shortened report for halfway through the nesting season. Every year, there is something NEW I LEARN. The trail is at 43 nestboxes. 3 boxes went unoccupied.  Last year, all boxes were eventually occupied. It’s not too late for them to be used, however, as I’ve seen late nestings in unoccupied boxes.   You know the 4-letter avian abbreviations?  They are as follows:

EABL:  Eastern bluebird, CACH:  Carolina Chickadee, TRES:  Tree Swallow, HOWR:  House Wren

…..EABL: 63 Nest Attempts / 270 Eggs Laid / 203 Hatched Thus Far and Pending More Hatchings / 155 Fledged Thus Far

…..CACH: 2 Nest Attempts / 9 Eggs Laid / 9 Hatched / 7 Fledged

…..TRES: 6 Nest Attempts / 27 Eggs Laid / 26 Hatched / 26 Fledged

…..HOWR: 1 Nest Attempt / 6 Eggs Laid / Pending Hatching. I should mention this nesting HOWR couple caused no havoc to native bird nestings. In the nestbox before them were bluebirds, which fledged successfully. After fledging, the HOWRs moved in within one week.. This is unusual. Competition is what would be expected. HOWRS’ migration arrival here was later than before.

……..1. RAT SNAKES ARE ON A RAMPAGE! 4 Nestboxes raided. 2 nestboxes armed with 6-inch wide wobbling stovepipe and pronged Noel Guard / 1 Nestbox armed with 7-inch wide wobbly stovepipe and pronged Noel Guard / 1 Nestbox armed with smooth (and waxed?) 4-inch PVC sleeve over wood post. This is the worse ever in 10 years regarding snakes — the very large rat snakes are challenging to hold back even 7-inch wide baffles. So far, no predations on the 8-inch wide wobbling stovepipe baffles. My trail is being updated with the 8-inch on remaining original setups. All new installations are higher at 6 feet high.

………2. BLOWFLY LARVAE INFESTATION WORST EVER IN 10 YEARS – 2nd broods were the worst affected. I am *increasing* on the food-grade organic diatomaceous earth application amounts in the nests of any remaining 2nd brood and all 3rd broods started. Some larvae got past the diatomaceous earth application (does that mean I did not add enough or these larvae are tougher than previous years? — a serious and chronic issue on my trail year after year!)

………3. Total number of missing or dead young—for all reasons—is now at 32 as of July 7. That is a very high number for my trail. Note: regarding missing young in a nest of surviving nestlings was not to predators; moreover I believe a hatchling died and the parent birds removed the deceased if they are small enough to pull through the 1.5 inch entry and exit hole from the nestbox.

I removed an unhatched egg today. I created a short video of how easy (and fast) I try to do this (attached). Only 1 of 2 eggs hatched.  See that below.  The nestling is growing slowly and is 72 hours old.   It is VERY hot outside right now.  Mom is holding her own.  I have not seen Pop Bluebird.

MONITORING: EASTERN BLUEBIRD NESTLING DAILY DEVELOPMENT GUIDE from CORNELL’s NESTWATCH


Eastern Bluebirds on Hatch Day.

Eastern Bluebirds on Hatch Day in 2014.   It never gets old seeing this during monitoring.  Be fast so that the naked and unfeathered young don’t get chilled on a day below 75 degrees.  That may be warm to us with clothes on, but these guys need to stay draft free as much as possible.  Take your photos quickly and move on.

 

This is an excellent daily photo journal of the nestling development and some behaviors of the young each day as they progress.  Here is the NestWatch page:  NestWatch Eastern Bluebird Nestling Development (Daily Nest Photos)

Please remember some good monitoring protocol for the safety of the nestlings and “courtesy” to the parent birds caring for their broods:

  1.  If you keep your own photo journal, try to abstain using flash after the young start to open their eyes on the 7th and 8th day — the flash photography is intrusive on cavity-nesting bird young. I set my small digital camera to the macro setting, which automatically turns off flash and adjusts focus for closeup photography.  Long periods of video photography could be intrusive.  Attempt to keep videos short-term.
  2. Please also be quick at the photos using a steady hand and try not to leave the box open too long — this will aid in keeping the smell of the young and any odors from the nest from unpicked up fecal sacs by the parent birds from floating into the air and attracting potential predators towards the young in the nest (snakes!).  I try to do all I need to do my checks in 45-60 seconds and close the box securely and leaving quietly. This includes using my auto visor mirror first for inspection, shut the box, ready my digital camera in the macro mode, reopening the box and shooting two photos and then closing the box again SECURELY and carefully and doing my skedaddle from the area so the parents and get back to business of caring for their young and keeping their stress level to a minimum.
  3. Also remember to abstain from opening your nesting boxes after the 13th day to avoid premature fledging of the nestlings.  Do your final check on the 12th or 13th day of the nestling’s age and stop at that point and do your behavior surveillance up to Fledge Day from a distance using binoculars in a comfy chair or bench in the vicinity of the nesting box — not too close because the parent birds won’t like you being there near this time and will delay fledging until they feel comfortable it’s safe for their offspring to make their maiden flights successfully–even wobbly so!–to the safe haven inside a tree and it’s foliage.  Yes, even you, the monitor the bluebirds have come to know still don’t want you nearby during the fledging process of their kids.  It’s just nature’s way of survival.
  4. Always keep good monitoring (accurate) records.  This will aid you determine their age, of course.  Monitor about 2-3 times a week for best accuracy of the goings on inside the nest box and for troubleshooting problems as they arise, BUT AT LEAST ONCE A WEEK MINIMUM…. but not too often (like every day unless the nesting box has problems) so you are not over-managing the birds.  After all, they are still wild birds–not your adopted pets.
  5. Send on your records to your local state bluebird society or ornithology organization like NestWatch or Audubon group!  They need the records, even from a back yard nesting box.  Find them online and see if there is a County Coordinator near you and contact them and introduce yourself.  You may make new friends at these wonderful NABS-affiliated non-profit, all volunteer cavity-nesting bird organizations.   You can also participate in Cornell’s NestWatch.   Here is their page to get started:  Cornell NestWatch Main Page

Happy Bluebirding to all!  More action on the trail’s Facebook page.  Questions directly to me are easier to access there and get quicker responses.  Come join us and the discussions there:  Woolwine House Bluebird Trail’s Facebook Page

Any questions?   Contact me directly here:  CONTACT ME BY EMAIL  or leave a blog note here.  I will do my best to answer as best I can.  I am out in the field often, so my office time and cell phone time is limited.  Thanks to all for the support.

TRAIL UPDATE – APRIL 27, 2016 – WE ARE ON OUR WAY TO A GREAT NESTING SEASON!


This Tree Swallow couple is having a blast, it appears.

Greetings this Wednesday, April 27th!  The trail is well on its way as of this date.  I have been very active on the Facebook page, but I would like to report in where we are thus far on first broods of the species — especially for those not following me and the trail activities on Facebook.

I am definitely seeing less species nesting on the trail this Spring with less nestboxes occupied — we’ve had a decrease of bluebird numbers in past three years in Virginia.  I am seeing less Tree Swallows and less Carolina Chickadees nesting, as well.  Of my 43 boxes, I have ten (10) NOT OCCUPIED by any species of bird at all.  This is a tad disappointing to me.  NO House Wrens and NO House Sparrows thus far.  But I am not saying they won’t try to nest.  I do know both species are in the area. The bright side of things are that my stats to date for first broods and species are as follows:

EABL: 121 EGGS, 81 HATCHED, 13 FLEDGED thus far–still have eggs to hatch and young to fledge.
CACH: 2 BOXES WITH 2 NESTS and 9 EGGS, both presently under incubation.
TRES: Late start! 4 BOXES WITH 4 NESTS started, no eggs yet.

One reason we NEED to monitor at least weekly is to take care of problems! If I did not take care of this issue, no birds will use this box, will they?

BUY A SHIRT / SAVE A BLUEBIRD!

A mere 50 years ago, the Eastern Bluebird suffered a steep decline in population, enough so that scientists feared for its survival.  This decline was due in part to severe weather, but also to human activities.  Habitat loss, removal of dead trees, the introduction of invasive species, pesticide use, cars, hunting, and collection of eggs all contributed to this decline.  Fortunately citizen scientists reversed the trend by introducing artificial housing in the form of nest boxes.  Now there is a large network of bluebird trails around the country, monitored weekly from spring through late summer.  The bluebird population has rebounded and stabilized.  With the purchase of this t-shirt (or two or three!), you can be a part of the effort to conserve bluebirds for many years to come.  Proceeds will be donated to organizations that help support Eastern Bluebird habitat.  Wouldn’t it be a great gift for all the bird lovers in your life?

Buying a shirt is easy.  Just go to https://www.bonfirefunds.com/buy-a-shirt-save-a-bluebird and follow the steps to place an order.  Shirts are $18 each, or $20 for a ladies slim fit.  We need a minimum of 20 orders by the end of the campaign on April 11 for the shirts to be produced and sent out.  If you’re unable to order online, just contact Alyce Quinn at twoquinns@yahoo.com or 540-719-0109 and she can order one for you.

‘KINGSTON’ STOVEPIPE BAFFLE — STOP GROUND PREDATORS GETTING TO NESTING BOXES.


This is the Ron Kingston Stovepipe guard.

This nestbox was recently treated for ants!

On the cusp of this Leap Year month, the nesting season is soon among us once again, and we must be sure our nesting boxes are protected so our beautiful native cavity-nesting birds can successfully fledge their young without sabotage and interruption.   It is up to us as humans — when installing manmade bird housing, that is — to add this protection.   We cannot do this in natural habitat in natural cavities much higher into the trees, but as stewards helping the native cavity-nesting birds, we can help by providing safe locations  for them to bring their young into the world when we install and lure the birds to use our manmade bird housing.  Predators from the ground are and can be, depending on your location:  Snakes, Raccoons, Cats, Opossum, Rats, Mice, and Squirrels.  Have I missed any?  (Will not stop ants.)  Mr. Ron Kingston and I keep in contact often.  Mr. Kingston, being the designer of this guard, has created an inexpensive-to-make but highly effective wobbling stovepipe guard to easily install under nesting boxes.  This design has been tested over and over on bluebird trails for many years.  He recently sent me this colorful PDF online document with more info with some awesome photo graphics on making this guard, including some nice info about Ron himself!  Thank you!   I have never seen it before. Here it is and linked from the Purple Martin Field Day (which occurs in June each day in Louisa County, Virginia):    Click here:   From the Purple Martin Field Day website

Yo, mama! She is guarding her egg clutch. The eggs can be counted on another day. If she sits right on the egg clutch when you open the box for monitiring, leave her be and quietly close the box and secure it. The eggs can be counted on another day! She is the boss and must be left to attend to her Mom duties. Please use predator guards so that Mrs. Blue will get attacked by snakes or climbing mammals like raccoons and cats. (Photo is by me in 2013, at a top-opening nestbox).

Let me know if you have questions either by posting here on this blog post or contacting me privately through the CONTACT ME page.  I will be duplicating this document on my “Deterring Predators and Pests” page also.  I am also linking the plan below how to make it in a PDF file, viewable and printable online below.

Suggestion: I install as high off the ground as possible so I can still reach the tops of boxes to monitor fast and efficiently without too much fuss during nestings so the birds can get back to business away from my human presence to tend to their nest and young.  I use an auto visor mirror to look down onto the nests to count eggs and young and to check for any possible problems with the young so I can troubleshoot how to help, just in case.  I install the stovepipe guards under my nestboxes fairly high from the ground–where the tops of my boxes are at about six (6) feet above ground.  Boxes installed too low, such as 4 feet (even 5 feet is low if you are installing a box on an incline terrain or hill), are too easy for snakes, raccoons, and cats, to get past the guard.  Feral cats can jump 6 feet!  (NOTE:  I prefer all my boxes to be off of flat terrain as much as possible.)

Here is a YouTube Video I made regarding one of my first boxes on my trail and using this guard:

“THE BLUEBIRD” … A POEM BY MAURICE THOMPSON


WHEN ice is thawed and snow is gone,
And racy sweetness floods the trees;
When snow-birds from the hedge have flown,
And on the hive-porch swarm the bees,
Drifting down the first warm wind
That thrills the earliest days of spring,
The bluebird seeks our maple groves,
And charms them into tasselling.

He sits among the delicate sprays,
With mists of splendor round him drawn,
And through the spring’s prophetic veil
Sees summer’s rich fulfilment dawn:
He sings, and his is nature’s voice—
A gush of melody sincere
From that great fount of harmony
Which thaws and runs when spring is here.

Short is his song, but strangely sweet
To ears aweary of the low,
Dull tramp of Winter’s sullen feet,
Sandalled in ice and muffed in snow:
Short is his song, but through it runs
A hint of dithyrambs yet to be—
A sweet suggestiveness that has
The influence of prophecy.

From childhood I have nursed a faith
In bluebirds’ songs and winds of spring:
They tell me, after frost and death
There comes a time of blossoming;
And after snow and cutting sleet,
The cold, stern mood of Nature yields
To tender warmth, when bare pink feet
Of children press her greening fields.

Sing strong and clear, O bluebird dear!
While all the land with splendor fills,
While maples gladden in the vales
And plum-trees blossom on the hills:
Float down the wind on shining wings,
And do thy will by grove and stream,
While through my life spring’s freshness runs
Like music through a poet’s dream.

 ~ by Maurice Thompson

CELEBRATING THE SUCCESS OF THE TRAIL — CHECK OUT THE RECORDS.


MY FAVORITE QUOTES (note I like the early year quotes the best!):

A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.”  ~  Letter, November 22, 1858, from Henry D. Thoreau to Daniel Ricketson, in The Writings of Henry David Thoreau, 1906

And when he sings to you, Though you’re deep in blue, You will see a ray of light creep through,  And so remember this, life is no abyss, Somewhere there’s a bluebird of happiness. Life is sweet, tender and complete, when you find the bluebird of happiness.” 
~  Bluebird of Happiness, lyrics by Edward Heyman & Harry Parr Davies, 1934

“As the pressure of population increasingly regiments us and crowds us closer together, an association with the wild, winged freedom of the birds will fill an ever growing need in our lives.”  ~ Edwin Way Teale, introduction to Songbirds in Your Garden, 1953

“The birds richly repay you for the trouble you take in attracting them and looking out for their interests.”   ~ Joseph H. Dodson, Your Bird Friends and How to Win Them, 1928

“The bluebird carries the sky on his back.” ~   Henry David Thoreau, Journal, April 3, 1852

This graphic below:  here is a pretty good indication of a bluebird trail success from Year 1 (2008) with the first 14 nestbox installations–though the trail planning and building stage actually started in 2007–to this year, 2015.  The more nesting boxes you put up and monitor, the more native cavity-nesting birds you can fledge!  This gives me great satisfaction for the hard work that has ensued from year to year.   The satisfaction of knowing I’ve helped fledge birds is worth all the effort, for sure.

WHBBT TOTAL BIRDS FLEDGED--ONE PAGE

It’s important to keep accurate records. I can look back on this and feel good about my past 10 years. That is really when I started keeping an eye out and monitoring bluebirds and other cavity-nesting birds….in 2005 and 2006….that’s when it really started for me.

WOOLWINE HOUSE BLUEBIRD TRAIL FINAL TRAIL RESULTS 2015 – SUMMARY 

The last set of bluebirds fledged early on Sunday, August 30, 2015.

43 Nestboxes Monitored 1-2 x Per Week (5 Were Unoccupied)

EASTERN BLUEBIRDS:

– 52 nest attempts

– 241 eggs laid

– 215 eggs hatched

– 211 bluebirds fledged

CAROLINA CHICKADEES:

– 3 nest attempts

– 16 eggs laid

– 15 eggs hatched

– 15 chickadees fledged

TREE SWALLOWS:

– 8 nest attempts

– 36 eggs laid

– 31 eggs hatched

– 25 tree swallows fledged

Predators:  

2 HOSP attack on Nextbox #34—destroyed TRES egg and 1 TRES fledgling killed just before fledging.  Neck and head pecked with huge hole behind head on top of neck area.  I chose not to post a picture, but I have one.  The hole on the back of the neck is huge.  It appeared the attack took place within a 48-hour period of time of my box check.

NO LOSSES due to blowfly larvae.  DE applied to all nests, all broods.  Only two or three nestings had no blowfly larvae found inside nesting material on nest inspection after fledging.  I will say some nest inspections still showed a few live larvae; obviously not enough to cause harm to the young.

1 Snake at PVC 6-inch width guard (a private nestbox by a homeowner) – resulted in loss of 4 EABL young after 13 days old.  Sometimes the PVC sleeve works; other times not.  The sleeve needs to be smoothed out and waxed periodically.  Sometimes any weed wacker around the base of the sleeve or mowing has cut grass clippings and thrown up dirt sticking to the PVC, creating a grip for predators.  Snakes will grip using their scales to that to cleverly maneuver their way up the sleeve.  The box is at 5 feet off the ground.   The box otherwise did well and fledged another brood after.  Appears to be a hit or miss on the snake there, probably the black rat snake, a native snake that I refuse to kill.   We need snakes to keep our rodent population down in the biological balance of things.  Other note is the rat snakes, being an expert climber, gets to other birds’ nests in trees and shrubs — much of nature we do not see at all.  If you use a PVC sleeve, try a wider one, keep it clean and smooth from any natural materials sticking to it, and use a carnauba car wax all the way top to bottom and buff it smooth.  This might help in future.  Keep wiping it down as necessary with a cloth to keep it free of debris.

Dead or Missing Young

8 — Either I removed or the parent birds removed.  One clutch of 5 feathered 12-day old TRES young died—inspected thoroughly for cause—NO TRAUMA and fully feathered–possibly starvation–possible poisoned from insecticides–do not know for sure.  Perhaps one or both parent TRES were killed and during a period of 3 days of rain, making it difficult for them to find flying insects to catch on wing.

Missing or Destroyed Eggs:   

5 — 1 TRES egg was destroyed and removed by HOSP in the school nestcam box.  The rest were removed by parent bluebirds or chickadees.

Unhatched/Unviable Eggs found on or inside nest:  

21

Other Interesting Notes and Events: 

I HAD ABSOLUTELY NO “ACTIVE” House Wren nestings and NO HOUSE WREN ATTACKS (predations) on other species eggs and young.  This is very unusual on my trail as last 3 years I’ve lost bluebird eggs and hatchlings due to House Wren attacks.  I did see a few sticks here and there dropped inside the nestboxes–one stick was dropped on 1 day old bluebird hatchlings.  Perhaps the parent bluebirds fought them off.  Theory only as I did not witness it.  I removed stick on top of the hatchlings.

I HAD ABSOLUTELY NO PREDATIONS of snakes, cats, or raccoons in my *protocol boxes* of pronged out Noel Guards and 8-inch wide wobbling stovepipe baffles.  This is cause for celebrations for me – a FIRST.   Last two years, I’ve had roaming housecats and possibly feral cats cause death to adult bluebirds (many with new hatchlings) getting ambushed on the ground while finding insects to feed their young.  This year, I did not find evidence of cat-caught bluebirds.  It does not mean it did not happen; however, usually I find the remains on the ground near the nestbox.  I was wondering if there was a loss of a parent bird at a few of the nestboxes.   Something got them, but I can’t determine what exactly:  either hit by a car, taken by a hawk, or taken be a cat, or killed by eating insects laced with pesticides.   I do not know.

I HAD ABSOLUTELY NO DEATHS to adult native cavity-nesting birds using my boxes due to HOSP attacks.  I did, however, lose one tree swallow ready-to-fledge in a brood of 4 by a HOSP attack.  Unfortunately this took place at the local elementary school’s nestcam box.   The better news is this attack did not take place while school was in session on live video projection!   This took place on or around the fledge date of the tree swallows near the date of July 20th.

I HAD ABSOLUTELY NO DEATHS to any species nestlings due to blowfly larvae, with thanks to puffing inside the nesting material food-grade organic diatomaceous earth.

I HAD NO Tree Swallow vs. Eastern Bluebird competition for nestboxes this season.  However, I did have a good year with increased tree swallow nestings.  Unfortunately, I did lose one brood of 5 12-day old tree swallows due to either eating insects laced with pesticides or from starvation.

AND MORE! …… READ ON BELOW:

The 2-Hole Mansion is in its 6th year of success EASTERN BLUEBIRDS vs. HOUSE SPARROWS.  No deaths of adult or nestlings from HOSP attacks.   The Mansion fledged 5 bluebirds this season.

I did have to remove two dead young from one nestbox (standard box) manually.  I was not able to determine cause of death.  It was in a box by a pasture — the removed nest was inspected and only dead blowfly were found inside the nest.  Perhaps those two young did not get enough food.  No trauma found on the remains.

What I thought was a nestbox setup knockdown by a bear with live tree swallow young was really a tractor during mowing.  The box, in a public park, is installed on a slight grade.  The mower evidently was on wet grass and slipped down and knocked the whole setup down with live young.  When I arrived (do not know how long it had been), the young were still inside alive and the parent birds were stressed flying around the area.  I was able to reinstalled the setup, all bent up, and get it back so that the parent birds could continue care for the young, which fledged 3 days later!  By the way, how I discovered this is one monitoring week or so later, I saw the mowers and wanted to introduce myself.  It was then they mentioned it to me when I told them I thought a bear knocked it down.  I gave them my contact info (a biz card I keep for my bluebird volunteering effort) and asked them to contact me by phone locally if they notice something wrong with my box setups in the park.   I do have a label with my phone number on all my boxes.

One nestbox had a mixed white and pale blue eggs.  I tried to determine if two females were laying, but could only witness one female bluebird at the box location during the week the eggs were laid, 1 by 1, each day.

Another box had a female bluebird lay 5 eggs, then another female bluebird entered a week later and laid her 4 eggs and buried the first female’s clutch.  There is a possibility they had a fight over the box or the first female bluebird was killed and the 2nd female found the nestbox soon after and used the nest.  The second clutch of 4 did hatch and fledge.  I found the first 5 eggs inside the nest material when I cleaned the box out.

In spite nesting was a month later this year than average, I had several nestboxes with 3 broods.

Latest fledge ever of bluebirds on the trail since 2007:  August 30th

I had a good year for Carolina Chickadee nestings.  Only 1 egg of 16 did not hatch.  All others hatched and fledged successfully.

Two nestboxes NOT my protocol and not my property were monitored that existed on installations with no predator guards.  One was a fence line/wood post on a local church’s grounds and the other was on the school property’s ball field on a utility pole.  Box boxes were at about 5.5 feet high off the ground.  Once I established species and final egg clutch laying completed, I fastened securely Noel Guards at those two nestboxes, pronged them out, and conducted twice-a-week surveillance of the nestboxes for activity using binoculars.   Both boxes fledged birds successfully—species were bluebirds.

I know from witnessing this that bird species WILL remove dead young if they are small enough to lift and exit from the 1.5” entry holes.   This is also true for unviable, unhatched eggs, though mostly either the eggs remain in the nest or get buried inside the nest by a parent bird.  In the instance I can do so, after the 4th day, I will try to manually remove unhatched eggs myself using a plastic spoon.

I am no longer experimenting with hardware cloth screen on nestbox floors.  Though I agree it helps with keeping nests drier, I do not find them helping keeping blowfly larvae from young as the larvae still sit inside the nest material at night, not falling below the nest through the gaps in the screens.  I am only using diatomaceous earth in ALL nests, all broods, to eradicate ALL parasites inside the nest material, mostly to eradicate blowfly larvae, but also mites and ants.

Due the nestboxes being well designed – the Carl Little Design – I have had NO WET NESTS from rain water getting inside the boxes and NO HEAT deaths due to inadequate ventilation, even with boxes in the sunlight.   The hottest day I logged this year along the trail was about 96 degrees.  Once it gets higher than 98, I would be concerned and would attempt to shade the boxes manually.  This was not necessary this year.

I did notice some nestboxes always occupied every year were NOT occupied this year.  I am thinking it is because we had a loss of bluebird populations in our area, all over Virginia, to severe winter weather and repeat freezing temperatures (enough to freeze homeowner’s pipes!).

I had one newly-installed nestbox by request of a neighbor that was late in the season (Memorial Day weekend).  It went unfound and unoccupied this year.  Next year, I expect it to be discovered and used.

Mixed color clutch. I watched this box daily. I did not see more than one female laying in this box. Each egg was laid consecutively each morning, one by one. It appears the first egg was pale blue, the second egg was even paler blue, than the next 3 eggs were white. Perhaps her pigment gene in her oviduct was weak--possibly a first time laying female.

Typical successful nestbox setup on my trail. Note the one-inch conduit, 8-inch wide wobbly stovepipe (blowing slight in the winds in this picture), stovepipe set up high on the one-inch conduit and just under the nestbox, the Carl Little nestbox design, with a vinyl-coated Noel Guard over the entry hole and PRONGED out to help deter any possible predator like slithering snakes that would get past that stovepipe. This nestbox is a new install for 2015. Pretty scenery.

I use a shallow white bucket to clean all fledged nests out of the nestboxes, including any detritus. I then dissect the used, soiled nests to see what's going on inside that nest during the nesting cycle. What I find inside is very educational. In this picture, you'll see DEAD BLOWFLY LARVAE. Thank you diatomaceous earth!

A box on a utility pole? This is a huge accident waiting to happen for nesting birds. I added a pronged out, sturdy Noel Guard--pronged out--and did a surveillance of activity on the box after I counted the final clutch of eggs. The baby bluebirds fledged. It is MUCH better to install boxes on poles and use predator guards under and on the nestbox. Installing nestboxes on 4x4 wood posts, fences, sidings of buildings, tree trunks, and on utility poles generally will not fledge bird families. It is just too easy for predators to get to this type installation. What's the point? This box is at 5.5 feet high off the ground. Again, note the Noel Guard is pronged out and away from bird feathers and is applied with 4 screws and washers on each corner.

“As long as there are bluebirds, there will be miracles and a way to find happiness.” – Shirl Brunnel, I Hear Bluebirds, 1984 ….. One of Mr. Kinneer’s splendid captures of Eastern Bluebird courtship.

Greetings to all.

The 2015 nesting season started later than in past years, but that is not a bad thing at all.  It tells me the birds waited for a reason. We had a harsh, cold, frigid winter late in the season 2014-15; and our early spring also was cold and dreary.  There appears to have been a few losses of bluebirds roosting in nestboxes — many reports are coming through to me of dead adults found inside the nestboxes this early February and March when the monitors were opening the nestboxes again.   The location of my trail, being in the Southern-Southwestern end of the state, has shown some results of some of my most successful nesting boxes not getting occupied thus far.   I have 42 installed setups on the trail now; of those 42, I still show at today’s date six nestbox setups not used by birds at all.   I am not disappointed, however; the rest of the trail is all good news.   I have nesting Eastern Bluebirds, Carolina Chickadees, and Tree Swallows.  I have had no House Sparrow attacks on young or adults and no havoc from the House Wren species.  As a matter of fact, I have NO House Wren sticks dropped inside any of my nestboxes – none!   This makes me wonder if this species, a migrating bird species, has had some issues this year.  Strangely, the past 3 years shows results of House Wren havoc on the Woolwine House Bluebird Trail.  This year, I show NO House Wrens.  I am not saying they won’t nest anytime soon. I have heard them singing in the trees attracting mates. I find it interesting the troubles housing this native species is not causing the usual concerns and worries I have had in past years.  We will see as time goes on for the rest of May and June this season.

For the followers of this site, my postings will be more few and far between as a blog setup as I try to maintain and keep this site going as an informational space about the joys of a bluebird trail, and all the challenges faced each year.  It has turned out the communications of my trail activities are going very well on Facebook, so if you want to see more weekly, even daily, postings of happenings on the trail, you can view the Facebook page, which is public, anytime, whether you are a Facebook user or not.  May I invite you to see the photos, videos, and challenges there in a more regular basis.   This page will be used as a “blog” with interesting reports that will come through from time to time.  Did you Know? … this blog started when I was telecommuting to my McLean, Virginia, position?  Something clicked when I worked from home, and what was happening outside my window made me realize the difference of working in an office—which I loved—to seeing the great outdoors.  I appreciate your support through the years.  The trail is celebrating its existence of fledging birds since my introduction to bluebirding in 2005 when I found an old weather nestbox in the back yard of our new home.  This box was on a 4×4 wood post without any predator guards.  As you may know, both bluebird broods failed miserably in that nestbox soon upon my arrival to the home.   That is how bluebirding with that fiery passion started for me.  The first of the bluebird trail of the first 14 nestboxes commenced with the planning during summer of 2007.  The boxes were built in the workshop (locally) during December and January 2007-08.  The 14 were installed February 2008.  Today, I have 42 nestboxes — many I install myself with no assistance.  I really think a total of 50 nestbox setups, all with two efficient predator guards, are not far-fetched. I have three active builders I work with throughout the state who do marvelous work and who I give credit to for allowing me to utilize their wonderful artistry and craftsmanship of creating super housing and the predator guards consisting now of 8” wide stovepipe baffles under the box and the Noel Guards on the entry holes to input successful results on my trail every year.  Thank you all for your assistance to make the Woolwine House Bluebird Trail a special place the native cavity-nesting birds enjoy rearing their families.   Many thanks also goes to the local homeowners who host the nestboxes and allow me to access the caretaking and monitoring required to make them work. The best reward for me is seeing this nesting action so close-up and being involved in seeing the young fledge into our world.

I am now a Certified Virginia Master Naturalist – received this honor in February 2014 by completing the requirements, including the volunteer hours to get certified.  Basic Training began August 2013.  This is giving me two naturalist course attendances and certifications during the last 3 years. This is coming very handy in me educating others on conservation of all of our natural resources, not just bluebirds.   I have many more things to learn as I continue on in my endeavors.   I am retired and I’m using my new time of choices to the max.  Taking care of cavity-nesting birds is just one of the many things I love in my life. There is no such thing as boredom. I have more time constraints than ever, it seems; and I’ve picked up even more hobbies, such as macro photography.  My favorite subject for macro is the wildflowers. I have three field guides in wildflowers in the Southern Appalachians.   I also want to learn more about one of the oldest creatures existing in my region – those magical salamanders.   Life is precious.  I vow to do the best I can to take care of myself first, and then do all I can to take care of others, human or critter.   For some reason, the natural calls me.  For sure, see the Virginia Master Naturalist main website to see all the great works the volunteers do — yo may want to consider training in your own State’s naturalist organization and become a Master Naturalist yourself.   http://www.virginiamasternaturalist.org/

Wishing you a beautiful season as spring is turning soon into summer. Feel free to use the Contact page to send me a private message, or reply to this blog with questions—better yet, if you want a faster response to questions, come to the Facebook page.   Best wishes to all.

EARLY FEEDBACK OF THIS NESTING SEASON 2014


The nesting season is starting to wind down. Of 36 nesting boxes, I still have 9 occupied presently with Eastern Bluebirds finishing 2nd broods. I have not seen 3rd broods started (yet). Since they started a month later last year and again this year (due to the colder weather), I doubt I’ll see 3rds this year. I have two nestboxes finishing up on House Wrens. My nesting boxes have had these species enter and attempt to nest. Only the House Sparrow was not allowed to reproduce in the boxes: House Sparrow, House Wren, Tree Swallow, Eastern Bluebird, and Carolina Chickadee. I was hoping to see this year at least once a White-Breasted Nuthatch, Brown-Headed Nuthatch (rare in our location but they are coming closer to our area in search of their specific habitat which is the Southern pine forests), or a Carolina Wren (sometimes will nest in nestboxes). Of all 36 monitored, not one nestbox went unoccupied. I’d say that’s “success” for housing 4 native cavity-nesting species of birds this season. The work to install them for occupancy has been tweaked just right by strategizing and accessing the usages year after year–always a work in progress when you start a bluebird trail. I will report back final nesting data in late August to early September.

TREE SWALLOWS!


They are nesting in a larger number on my trail for 2014!

This TRES couple took over a bluebird nest that had a cluth of 5 bluebird eggs.  Not sure if it was the TRES or a HOWR or a HOSP that broke the eggs in this area.   Some species did--and it was not mammal.

EASTERN BLUEBIRD WARBLE — NESTING SEASON 2014 HAS BEGUN.


My trail is finally in active nestings!   There were days of warmth, then snow.  Then very cold nights and more roosting birds without nests.  These guys know what to do.  Nesting and laying eggs is not one of them when it’s too cold out!   I think winter is over now.  Nest cups are formed and the first eggs have been laid in one of my boxes on March 31 as the date of the first egg laid.  However, the House Wren beat that, but I don’t have a date of that laid clutch, unfortunately.  Surprisingly, I’ve not witnessed ANY species competition among the nestboxes…yet, that is.  I expect to see those soon.  Fastest House Wren I’ve ever seen!

Presently, my early trail stats are as follows for the 2014 nesting season:

Eastern Bluebird (EABL):m 14 partial or completed nests thus far.

Carolina Chickadee (CACH):   1 with no eggs laid yet.

House Wren (HOWR):  1 with 5 eggs

Tree Swallow (TRES): 1 –  It’s either a TRES or EABL.  Need to go back to confirm.

 

Here is a video.  Enjoy.   Woolwine House Bluebird Trail First Eggs for 2014 Season

 

Hoping you’re getting some great action now. Enjoy your nesting birds!

 

BLUEBIRD TRAIL MONITORING — TOOLS OF THE TRAIL! WHAT’S IN MY TRAIL BAG?


Check out all the tools and "stuff" that helps me on the trail.  Can you guess what everything is for?  This is pretty typical of my 1-2 x a week monitoring tools I take to each nestbox.

Check out all the nifty tools and “stuff” that helps me on the trail. Can you guess what everything is for? This is pretty typical of my 1-2 x a week monitoring tools I take to each nestbox.  FYI, if you have a backyard nestbox, this won’t be necessary.  When I check my bluebird trail, I need everything handy in one place to save me time and effort.

I am posting this picture (above) to show you what’s inside my bluebird trail tool / tack bag — current from 2013 and for what I’ll use for 2014.   You can look at my contents, and I’ll repost in two weeks with the full list and what I use everything for.  HINT: This does NOT include what I keep in the back of my car, which is reflected in the picture below.  My trail bag is shown in the second picture–it is yellow and black and made by Stanley (top left of second photo).   I can tell you I use all items within one nesting season — March through August.   It is hard to believe all this can fit in a small bag, but it does.   If it helps you understand, it has taken several years to tweak what I need and what I don’t need.  This might be more than some would use–perhaps not enough for others.   This will vary on your own nesting boxes you monitor and how many and the problems you have to deal with.   Best to start small and add on as you get experienced.  What might be fun for you experienced monitors:  add your thoughts to this blog before I come back in two weeks.  What is missing here that you use often on monitoring your bluebird trails and why do you need that item?  Have fun with this.  I hope I spark some questions on this post!  See you in two weeks.  I will post the list of items and what I use them for.  See you soon!   Today is February 25th (2014) and I’ll be back on March 11th!

I have a rolling workshop!   This is the back of my car--the things I don't carry in my trail bag but have handy on the trail, if needed.

GEARING UP — BLUEBIRD NESTING SEASON FOR 2014.


Nestbox Installation on the Woolwine House Bluebird Trail - February 2014 - may be more soon!

Nestbox Installation on the Woolwine House Bluebird Trail – February 2014 – may be more soon!

Have you seen plenty of fluttering of wings on with those brilliant blue males establishing breeding territory and sitting on your existing nestboxes?   It’s that time.   Is it still just too cold for that and are you laden with snow cover and ice?  Are your boxes ready–cleaned, repaired, and ready for those new, fresh nesting materials and for the human monitoring we need to do?

I have been spending time educating others in public talks and in training others on the joys and sometimes challenges in monitoring nestboxes.  Now I need to get my own monitoring sheets ready and get my notebook updated.  I’m adding more nesting boxes this year–not too many more–I need to maintain weekly monitoring and keep those accurate records.

Thank goodness for the volunteers from the Virginia Master Naturalists, who will be getting some training in my local area to help me on my own bluebird trail and other trails in our area in Southwest VA on public lands!  I’m very grateful for such hard-working folks who volunteer their valuable time to help our natural world, whether it is birds, mammals, native plants, water monitoring so much more and whatever is needed.   I, too, am close to certification myself as a Virginia Master Naturalist by just a few more volunteer hours.   It’s a good feeling to accomplish tasks that is highly worthwhile and to keep learning!

I will do all I can to keep you up to date on the Woolwine House Bluebird Trail and also on the Facebook page, which is a very informative page for many who are active on social networking and can get updates to their News Feeds from my trail happenings.   As soon as I get my first egg, I’ll report in!   Thanks for your continued support.   All the best to you and your birds during our upcoming spring.   By all mean, let me know if I can help in any way.  I’ll do what I can to answer your questions on this site or on the Facebook page.   Happy Spring to all–whenever it gets here. We had 21 inches of snow a few weeks ago–unusual for our area–and we were snowed in for 5 days. Then it got up to 65-70 degrees for two days — the Polar Vortex has now returned!    The birds will pace themselves when they feel the time is right–the incubating female can hold egg laying until she’s comfortable doing so.  I’ve seen her lay a couple, and then delay a few days during very sudden cold snaps, and come back a few days later and lay a couple more to complete the clutch.

TREE SWALLOWS HATCHING!


All of these lovely feathers--such a cozy place to come out of the environment of a shell to this softness and caring of the tree swallow parents.  So tiny--so in need of care and protection of a nest.

All of these lovely feathers–such a cozy place to come out of the environment of a shell to this softness and caring of the tree swallow parents. Son tiny–so in need of care and protection of a nest.

Here is my first Tree Swallows on the trail–hatching started June 10, 2013. I’ve waited a long time to have this species nest on my trail. I hope they do well.

PAINTING POLES AND BAFFLES, DEALING WITH WEEDY GROWTH, AND FLEDGING BABY BIRDS.


I really like this setup--and so do the nesting birds.  This is an Eastern Bluebird nest in progress.  Wahoo!

I really like this setup–and so do the nesting birds. This is an Eastern Bluebird nest in progress. Wahoo!

 Like my paint job?  Once the weedy growth was mowed farther away from this setup, the bluebirds returned--a very successful nestbox again for 2013.

Once the weedy growth was mowed farther away from this setup, the bluebirds returned–a very successful nestbox again for 2013.  LIke my paint job?  Would you believe I painted the conduit and the stovepipe AFTER this nestbox was already installed?  How?  Very carefully, when birds were not using it, and taping small pieces of newspaper all over the nestbox, that’s how!  See this post on materials used, including the primer info.   Yes, I primed the galvanized stovepipe, and then spray painted.   I’m pretty happy with the results so far.

This second photo here was taken late summer (August) 2012.  That tall weedy growth grew suddenly (fast spreading in the South) in 2012 was a problem being too close to the nestbox that was installed in 2009.  This nestbox is usually very successful–consistent 2-3 broods until the weeds grew up around it.  The bluebirds did not like it and did NOT nest in it during the 2012 season–AT ALL!  It was tough stuff to deal with, let alone getting chiggers and ticks on me. This year, it’s being mowed down in a wider swatch around this nestbox–not all of it but a large circle around it is being cleared, thanks to my neighbor, Carl, using a weedwacker and also me using a hand-grass and weed cutter (I had to cover myself up in long sleeves and pants and camp hat and put some bug deterrent on my face and neck).  Getting chigger bites and ticks is not fun.   I don’t find this nestbox with two predator guards unsightly at all.   The Noel Guard seems to disappear in this photo.  What is most beautiful to me, however, is successfully fledging native baby birds–a big YES to bluebirds (as you can see in the first photo! Do you like my spray paint job on the pole and galvanized stovepipe baffle? I used Rust-Oleum Ultra Cover 2X Primer and 2 X Semi-Gloss spray paint: http://www.thepaintstore.com/ULTRA_COVER_2X_s/273.htm

In these photos, one Noel Guard is unpainted galvanized 1/2″ hardware cloth (looks grey) and the other is vinyl-coated green 1/2″ hardware cloth.  I like the vinyl-coated best.  Please also note I am experimenting with different designs of stovepipe baffles — the Ron Kingston (most effective (!) using hardware cloth inside the stovepipe and an 8″ width), and the less wide 6″ stovepipe baffle with a duct cap at the top.  I’m keeping notes as I see effectiveness for both designs.   I’m also trying the 7″ width on my trail.  Nonetheless, please USE something to deter ground predators.   Raccoons and Black Rat Snakes, even mice, can climb smooth conduits and even PVC slipped over conduits.   If you grease them, whatever the grease you use, becomes ineffective in time, so you have to keep that up.  I cannot keep that up with 34 nesting sites.  I do NOT grease any of these stovepipe designs.  I will check back at the end of the nesting season to report my findings if any predators got past any of the designs.  It can happen, yes…..they are not 100 percent foolproof…….but 99 percent isn’t too shabby of a record!

All bird species using the nesting boxes on my trail do not mind entering the nesting boxes and actually like the Noel Guard–this is what makes me the happiest (and gives me peace of mind using the guards).  I know the extra effort is helping them, but I don’t want to take the time to install nesting sites like this and monitor weekly and find failure–that’s wasted effort, in my humble opinion.  When I visit the boxes, I want to put in my notebook “FLEDGED” and then send on those records to the Virginia Bluebird Society, the North American Bluebird Society (gets the data from the affiliate bluebird clubs from each state), and Cornell’s NestWatch, which I participate, as well.  I’m pretty busy these days.   I need to be sure I get my rest.

Happy (and safe) Bluebirding!

HOW ‘BOUT THIS? A CLUTCH OF SIX WHITE BLUEBIRD EGGS!


EGG-CITE FOR WHITE!

WHITE BLUEBIRD EGGS? It happens. Approximately 5% laying female bluebirds are missing the pigment gene to color the eggs blue as they pass through her oviduct. The eggs are just as fertile, generally, as the blue ones.  Note the slightly pinkish hue.  I’ve seen them before actually pure white.  When I first saw those feathers, I thought Tree Swallows.  But no, they are bluebirds.  There are not enough of the right feathers for TRES and I saw the pair in the tree above me anyway.   To read up more about white bluebird eggs, here is a great page for that: http://www.sialis.org/whiteeggs.htm

WHAT’s IN MY BAG?


Coming soon…..”what’s in my bag?” upcoming post….photos and explanations of what I carry with me when I monitor the bluebird trail.  A work in progress–there will be three parts to this series on this topic:

~ Part 1 (first post) is the bag I use and what’s in the bag and why I carry the items on every nestbox check.

~ Part 2 (second post a few days later) will be what I keep in the car on most nestbox visits (but not always carried to each box when monitoring them).

~ and Part 3 (third and probably the last post in the series ) will be the extra stuff to keep on hand, if needed — what I found helpful to have around for different circumstances…and why.

Every monitor has tools they like the best–for different reasons.  Not everyone will be the same.  Some tools might be what every monitor will always have.  This will be mine–am happy to share with you what I like to use.  I started monitoring nestboxes in 2006 and 2007.  The Woolwine House Bluebird Trail started February 2008.  As the monitor and caretaker of this trail and after all these years and experiences, I’ve tweaked my bag.  Stay tuned!  Here is a sneak preview–the bag I’ve used thus far that really works for me!  It’s new–just purchased it this winter.  Bottom line:  use what works for you!  The point is:  MONITOR your nestboxes.  Use the tools to make it work for you.  The native cavity-nesting birds need you to do so to help them succeed in case there are problems with the manmade nestbox you put up for them.    Do you need more info on monitoring?  Here is a great place to start (North American Bluebird Society Fact Sheet on Monitoring) — PDF file is downloadable and printable!  http://www.nabluebirdsociety.org/PDF/FAQ/NABS%20factsheet%20-%20Monitoring%20-%2024May12%20DRAFT.pdf

This Stanley-brand bag is perfect for me to carry what I need!   Not expensive!  It's about the size of a ladies handbag.

HERE COME THE NESTINGS!


March 19 – 2013:   Nestbox checks searching for new nestings has official commenced for 2013 season.  I visited all boxes on the trail.  Out of the 33 nestboxes I am care-taking, four (4) had new bluebird nests started.  I am thinking they are one or two days into building time.  You know, when Mr. Blue does good husbandry and helps find nest materials and drops them inside the box, it is faster for her.  I am waiting to see tree swallows and chickadees (really hoping for those swallows this year).   I am expecting some house wrens in another location.  Here are two new photos.  The first is the one nestbox that has the most materials–grasses being dropped and arranged by Mrs. Blue in that circular design.   The other photo is the latest addition to my trail–the last nestbox (#33).  You will note the 8″ width, spray-painted stovepipe wobbling snake/ground critter guard on the conduit and the extra predator guard (original called the Jim Noel Coon Guard) made of hardware cloth over the entry hole.   So, here we go, folks!   Wishing everyone a blessed bluebird year!  “May All Your Blues Be Birds” !  by B. Zimmerman

#18 - This box had the most amount of materials of the 4 that had nests started.  This is much later than last year.  I'm sure the colder weather is making a difference when these birds decide to start the raise-the-family thing they do!

SNAKE GUARDS (WOBBLING HANGING STOVEPIPE)…EFFECTIVE AGAINST MOST GROUND PREDATORS!


Here is a great photo of a black rat snake in action.   Photo posted on the Roanoke Valley Bird Club’s (RVBC) website under their Bluebird Trail page:    Source:    http://www.roanokevalleybirdclub.com/Bluebird%20Trail.html

I talked with the person who took this picture (Mr. Earl Morris, RVBC active member and County Coordinator, Virginia Bluebird Society (VBS).  It was witnessed this snake made three attempts to get past this stovepipe guard, unsuccessfully, and finally gave up.  There were active bluebirds nesting inside this nestbox.   This is a good example of how effective this design guard is to deter *most* ground-roaming critters.  It is a wobbling stovepip (duct) guard, and it deters more than just snakes!  It keeps other ground critters from getting up to the nestbox, too; not just the crafty black rat snake:  raccoons, squirrels, mice, cats….to name a few.  There are several places to get the design to build your own — inespensive to make:

THE CAT/RACCOON GUARD: BLUEBIRDS LIKE THEM (AND USE THEM). RECOMMENDED BY THE VIRGINIA BLUEBIRD SOCIETY.


The newest design plan is on the VBS website.   My next batch of guards when I expand my trail will be the recommended “coated” hardware cloth!  Also, I’ve seen Tree Swallows use this with ease.  Also House Wrens and the Carolina Chickadees don’t mind them I am discovering bluebirds like to leave some of their nesting materials, either soft dried grasses or pine needles, inside this entry-hole hardware cloth guard, also known as the Noel Guard (designed by Jim Noel) just underneath the entry hole. Maybe I’m wrong, but I think this is their way of telling other birds, “AHEM! OCCUPIED” ….. and just so you know, we have this box so you may stay away!” It’s fairly consistent with bluebirds on my own trail. They like the guard to sit on and watch over their nestbox! Here is a picture of one of the boxes along my trail. You can see some of their nest material dropped in it. When I’m checking my boxes for new nests being built, this is a sure sign something good is going on inside the box! Though some people think they are not attractive; however, for me, it’s more important to enjoy the beauty of a successful fledging of baby bluebirds than finding a tragedy instead.

 Plan to build this:     http://www.virginiabluebirds.org/forms/bb-guards_03-27-2011.pdf

Bluebirds like this guard. Most of the boxes on my trail show nesting materials laid on it under the entry hole. It looks like a sign to other bird species: OCCUPIED!

THE LOVELY TREE SWALLOW — A NATIVE CAVITY-NESTING BIRD USING OUR NESTBOXES.


I have long waited doing this post on the Tree Swallow.   My first year of my trail (2008) had paired nestboxes because I had seen tree swallows dive-bombing searching for insects over our pond.  I did pair the boxes 15 feet apart on 1” conduits with two predator guards on each paired setup.   Much to my disappointment, no tree swallows used any of the paired boxes on my property.  I still do not know why.   The next year, I unpaired the boxes in February and moved them elsewhere in my community as part of the Woolwine House Bluebird Trail.  The reason I was a little disappointed is this.  For me, the Tree Swallow (TRES) is just as beautiful, just as graceful, and just as much allowable to use nestboxes we made for bluebirds.  REASONS:  1.  They are a beautiful cavity-nesting native bird that also cannot excavate their own cavities.  2. Unlike our Eastern Bluebird (EABL) here in Virginia that has 2-3 broods per nesting season, the TRES has one brood per nesting season. 3.  Tree swallows are aerial foragers for food, namely insects,  as their main food source.  Bluebirds generally forage for insects perched, obtaining insects—grubs, grasshoppers, spiders, crickets, etc.–from the ground.  You’ll see them cocking their heads to the sides, pointing their heads down as they use their good eyes to find that insect and then flying down quickly to retrieve it.   I have also watched a bluebird male in a flash fly out of a poplar tree behind our house and catch a large white moth mid-air.  That is a sight to see!   The tree swallow has to work harder, swooping here and there, dive-bombing using their wings and forked tail for leverage as they catch their food mid-flight-mid-air.  They are a delight to watch.  You can imagine eating for themselves and feeding their brood how much work that is from dawn to dusk.

I have had people ask about this bird competing for a nestbox–my reaction is always enthusiastic, as it’s been my wish to be able to monitor this gorgeous bird for myself, along with other cavity nesters.  I have not had that opportunity yet to monitor a nesting pair of tree swallows.  I still wait to see it on my own trail, and I still hope it will happen, as I do see them in our area.   I am fascinated with the nest building of the TRES, as it will fly for many miles from its chosen nesting site to obtain large feathers from other birds to place on top of its nest materials of grasses, such as goose feathers or other waterfowl feathers.  You will see the TRES near agricultural fields (open habitat just like the bluebird) and many times near water sources, such as ponds if available, probably for the reason of finding waterfowl feathers there and insects being available surrounding the ponds, such as dragonflies that I see by our pond.  This bird is marked strikingly, particularly the male, with a bright white neck and belly and a greenish-violet-iridescent blue on its back and wings.  It’s a gentle, assertive bird, as I have stood next to a monitor in one of my counties at a newly-installed nestbox just 4 feet away and watched a female enter to build the nest and the male sitting on top guarding the box and looking at me as if to say, “Hey there—hope you don’t mind us using this box you installed.   First come-first serve, so thank you for providing us this perfect nesting place!”  Of course, I smiled, and the new monitor I was training appeared seemingly a little disappointed, because she also wanted bluebirds.   I immediately explained that this bird, the tree swallow, has the same issue as the bluebirds with needing nesting sites which is cavity only and having the same challenge as bluebirds in finding “available” cavities to raise a family, in natural habitat, used woodpecker holes for nests.

With many thanks to a new monitor in Floyd County who has been taking excellent photographs of bluebirds and tree swallows nesting in some of her nestboxes, I can now share this wonderful bird with you here on the Woolwine House Bluebird Trail’s website.  Many thanks, Karen, for sharing these lovely pictures of this bird which you are lucky to be able to see a nesting cycle.  Many of our cavity nesters have one brood per season, so after the TRES are completed, you may get a second or third brood
nesting cycle from our beloved bluebirds after…perhaps another native species.   It’s all part of the fun of monitoring, isn’t it?

I will be highlighting other cavity-nesting birds that use nestboxes shortly.  In my opinion as a trail monitor, trail manager, and trainer to new bluebirders, I find monitoring other bird species helps us learn more about our native birds and the joys of monitoring brings variety of experiences  and joys to being a good landlord of our nestboxes.  If you find you have both bluebirds and tree swallows where you have one or more nestboxes, they will nest peacefully side by side with each other if you pair your boxes 5-20 feet apart.  Some have actually put two nestboxes on one pole.  I have included a video of that below the photo set, which you may find interesting.   This box was installed on PVC, looks like about 4” wide, with a cap on
the PVC.  I’ve seen other setups with one pole and the boxes installed with opposite directions for the entry hole.  I have heard stories from others who have successful nesting of tree swallows and bluebirds of a bluebird parent feeding a tree swallow set of nestlings when one of the tree swallow parents disappeared (probably killed).  They WILL nest next to each other if they don’t feel threatened by the other.  However, if you have one box, there COULD be the usual territorial war over the nestbox, understandably so, since both birds need an available cavity to bring up a family.  I’ve seen this with chickadees and bluebirds on my trail this year.  If this happens, you could quickly install another box right away near the other one where the competition is taking place.   You then could have both birds nesting as friendly neighbors–all the while monitoring, enjoying them, keeping notes, and seeing behaviorial antics, some similar and some different.   I still recommend the two predator guards on a pole because of the amount of predation we get here in Virginia, both ground and avian predators.  As a monitor, I want success, so I go all out to be sure the birds can be protected.   If I put up a nestbox for the birds, the least I can do is help them succeed.  Otherwise, the time and expense of installing a nestbox seems fruitless–as I say, it’s like luring them to use your setup and then playing a practical joke on them because we make it easy for those predators to get to them.  It’s not my style of managing nestboxes.

I hope you enjoy the 5 pictures posted below—photos by Karen Hale in Floyd County, VA.   I adore the Tree Swallow—I want to have some nest in my boxes SOON.  Thanks, Karen!  I support all native birds.  Lucky we humans it’s not always bluebirds we are helping.  My next post will be about the  fascinating Brown-headed Nuthatch…a bird found in the South near pine forests.  Stay tuned!

In the meantime, underneath these photos I have linked direct viewing to a YouTube video of bluebirds and tree swallows nesting side-by-side and the Cornell Lab of Ornithology’s info page on the Tree Swallow.  There you can also hear what the TRES song sounds like–a chittering sound that requires good listening ears to ID.  I hope you enjoy.  Questions and comments welcomed and encouraged on this post!

Great photo of pinkish-white eggs. Tree swallows have white eggs, but they appear to have some pink hue here, probably because of the lighting. This is a good-size mirror for seeing a nest in its entirety and taking photographs. Of course, as monitors, when we do this--we learn to be quiet and fast so as not to stress the nesting parents too much. Good job!

Great photo of the couple resting on a nearby fenceline. The male is on the left. Like the female bluebird, the female tree swallow is a muted grayish-blue. Depending on how the sunlight hits them, the coloring can be bright hues of blues-violet-greens! They have tiny bills, like the bluebird. If you go to the Cornell "All About Birds" link at the bottom of this post, you'll see an outline of the bird in flight--forkish-pointy wings and tail.

This is one of the most exciting moments of monitoring nestboxes!

See how the soft feathers are placed on the nest. These young nestlings cannot hold their heavy heads up yet.

All 5 are doing well. They will be ready to fledge in about 20-24 days from hatching date. Both the male and female feed their young, like the bluebirds. When adults, these guys will join large flocks and migrate. They need to do this to get insects in the winter. Bluebirds eat berries in the winter, so many of our bluebirds in Southwest Virginia stay as residents.

WINTERIZING NESTBOXES


Winterizing Material 2

I will be out on my trail next week to winterize all the boxes so that the bluebirds and other cavity nesters can roost in the boxes. 

What is winterizing?

The ventilation areas of each box will be plugged to keep cold drafts and rain and snow out of the boxes while the birds keep warm in them.  The only sections NOT plugged will be the drainage holes in the box floors and the entry holes, of course!

Winterizing Material for NestboxesWinterizing Material 1

See  a series of pictures below of winterized boxes on my trail.  You’ll see how the materials help keep the boxes warm!

Also next week, two of my boxes will be moved to new locations.   My criteria for changing is the current box locations were not used by cavity nesters this past season.  It’s good to tweak the trail each year for best use of all nestboxes available for the birds! BBIce-AllRightsResered-DaveKinneer-UsedWithPermission-CBoran2009The Virginia Bluebird Society’s  website  helped me when I went to Lowe’s Home Improvement to get the supplies…  cost was $14 for everything and all the materials can be recycled again for the next winter season!

I run across this during winterizing….mud dauber wasp nests. There are pupae inside these mud tunnels. Remove with scraper.  The nests are built in the late summer and early fall for larvae to “overwinter” and hatch in spring.   Destroy mud nests and larvae (I just crush in the ground thoroughly with my boots!)
