Flying the Coop

It’s been a while since I’ve posted because I’ve been so busy lately! On either May 22nd or early May 23rd, the Black-capped Chickadees in my nest box fledged. There were either 2 or 3 nestlings based on my observations on May 22nd.

On the 22nd, I watched both parents feed at the entry hole every 5 minutes or so and often fly off with fecal packets. Between parental visits, one nestling, noticeable as a nestling by its fleshy gape, kept sticking its head out of the hole of the nest box and looking around as if it was ready to jump out at any minute.

When I checked the next morning, the birds were gone. Next year I’ll try and rig up the nest box camera to see if I can’t capture the whole show. Since the box I’m using is pretty small, I may need to develop a false roof to attach the camera.

My Little Chickadee

On March 29th, I finally got around to putting up the chickadee nest box I bought last year. Like with my flicker box, I targeted the Black-capped Chickadee as a potential yard tenant based on the fact I had a handful of them already hanging around and eating from my bird feeder. Well, on March 30th, I noticed a chickadee going in and out of the box and on April 6th, the pair already had a complete nest!

There are 7 chickadee species in North America and all are cavity-nesters. When I lived in Virginia, my backyard chickadee was the Carolina Chickadee, which tends to have a more southerly range than the Black-capped Chickadees I now encounter. Like the Northern Flicker, the Black-capped Chickadee will readily use a nest box. Of  course, the chickadee is much smaller than the flicker, so it needs a smaller box. A good idea to keep birds like European Starlings and, especially, House Sparrows, away, is to buy or make a box with an entry hole too small for those birds to enter. I bought a hole guard made of metal to screw over the entry hole. The guard is 1 1/8 inches in diameter, which is perfect for the chickadees to squeeze through, but too small for those other bully birds.

Also unlike the Northern Flicker, which lays her eggs directly in the wood chips at the bottom of the cavity she’s chosen, the Black-capped Chickadee will build a nest inside her cavity of choice on top of the wood chips. The female constructs the nest using mosses, evergreen needles, bark, and other coarse materials¬†as a base, which she then lines with softer material like animal fur and plant fibers like milkweed fluff. Only the female chickadee incubates the eggs.

Because I didn’t realize the chickadees would be so quick to start nesting, I didn’t get a nest camera installed beforehand, but I’m planning on putting one up next year. In the meantime, I’ll try to document the nest attempt as best I can. Chickadees are more sensitive to monitoring than bluebirds, so I probably won’t be checking the box too frequently lest I cause them to abandon it.
