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:

I found this enlightening….bluebirds will hold their own and protect their territory. The bluebird nest was started, so they were first. Upon returning, it was discovered this chickadee appeared “interested” in this box. See what happens. Who says bluebirds are ALWAYS kind and gentle creatures? Well, OK, usually they are. Enjoy seeing what competitors do to keep prime real estate–our manmade nesting boxes, of course! Humorous and educational material here. Good job on the video making, I say.



We have completed first broods–I have had five species of cavity-nesting birds use my nesting boxes on the trail! Second nestings have started, some egg clutches laid.

I am sharing this fun video of the Noel Guard efficiency, in particular, in deterring raccoons from getting inside nest boxes and taking out eggs and nestlings. I just posted this to my Facebook page and want to share it on my website/blog. Raccoons are in rural areas and suburbs and can get inside back yards that are fenced. This is an excellent, humorous look at how crafty the raccoon is to getting inside nestboxes pulling out eggs and nestlings for a “midnight snack”. I keep this Noel Guard (made from sturdy 1/2 inch hardware cloth–note the length) on all of my nestboxes except my two-hole mansion (which is deeper). This guard also keeps out roaming housecats, feral cats, and large avian predators. I get all bird species inside nestboxes, including roosting birds in the winter, so I know they do NOT deter the birds. What surprised me on this was at the end showing the bluebirds figuring out the extra “obstacle course” that was installed inside the Noel Guard. Bluebirds are just as smart and just as agile as raccoons. Since my nesting boxes have two predator guards, I can attest I have 99 percent success on my bluebird trail from most predators. I do not care one bit that some people do not find them “pretty”. The bluebirds like them, and that is good enough for me. Also note that the Noel Guard does not keep out House Sparrows (also a predator) or House Wrens (a harasser bird to other cavity-nesting birds’ eggs and young). I am dealing with House Sparrows and House Wrens, however, so I’m not problem-free, for sure. Tip: When installing this guard, be sure it’s installed using washers and screws–raccoons are strong creatures. Staples are not strong enough. Fun 9 minute video–truly hope you enjoy it to some bluegrass music. Sharing from the Virginia Bluebird Society’s FB page (thanks for posting!). As far as I am concerned, I’m in enjoying cavity-nesters and in a conservation effort for species like the bluebirds and even chickadees that have only one brood per year. I feel by providing a safe nesting site for them using predator guards, they can succeed in a more stress-reduced place to raise and fledge their families.

This pretty lady says “No way am I budging!” …. brave one she is. I took the photo and decided to count the eggs in this clutch on another day. I will not force her from her important Mom duties. When I left the box, I thanked her for her patience with me. This was taken on Friday, April 12, 2013, in a top-opening nestbox.
