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.

Mom blue Incubating 2016 at Nestbox 15

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!

BUY A SHIRT / SAVE A BLUEBIRD! – Fundraiser Campaign to Support Bluebirds – Deadline is April 11, 2016.


I’m getting the word out for my bluebirding friend and colleague, Alyce, a member of the Roanoke Valley Bird Club, a longtime birding fan and monitor of bluebird trails in Virginia.  If you love the Blues, you’re going to love this shirt!    I’m ordering a couple for myself and a couple as gifts.  Orders can be placed until April 11! …. the deadline to order for this campaign.  THANK YOU for your support!

T-shirt comes in Khaki color. Fabric is a poly-cotton blend, 50/50--are pre-shrunk and run to size.

Fabric is a poly-cotton blend, 50/50–pre-shrunk and run to size (unless otherwise noted).

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 is the Ron Kingston Stovepipe guard.

This nestbox was recently treated for ants!

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.

3.  From Cornell’s NestWatch page on predators (includes info on the wonderful Noel guard):

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:

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.

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

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:

SOME TRAIL NOTES


NOTABLE WEEKLY WHBBT UPDATES:

May 29 — I was disappointed not to find second-brood nesters just yet.  We have had some strange weather lately–hard rains, thunderstorms, and flash flooding warnings.  Today was a break with some sun for my trail checks.  There ARE still two boxes I need to check but I ran out of time.  I’ll go back tomorrow to check those.  Some of the empty boxes from the first broods had the beginnings of small tiny black ants!  This is a “first” for me on my trail.  I treated the boxes, will return again sometime this Holiday weekend to make sure they are clean and dry and will apply vaseline at the bottom of the poles to deter the ants to crawl back up.

So far no more paper wasp or mud dauber wasp problems in my boxes this season.   It’s not as bad this season as last season for some reason.  I also found out recently the Cornell’s hosted Bluebird-L bluebird list has ended, and the group has moved over to Yahoo Groups.  I’ll be getting on that today–been delayed in getting things done.   Now that my presentation/workshop at the Reynold’s Homestead is behind me, I can catch up a little.   I am very happy with my PowerPoint presentation, displays, and handouts.   It was hard work to get it all together, but it’s worth it when I know it helps others understand more the content of proper bluebirding.  I am prepared with my DE applications for the second nests to keep blowfly larvae from bothering baby birds!  So….see you next update, in about a week.
