I have a birdhouse mounted to the exterior of my classroom windowsill. It's a bluebird nesting box that was specially built as a gift for use in my classroom. The bottom and 3 of the sides are made of wood, and the wooden top has hinges to open and close the box. The really cool part is the back wall of the birdhouse. This is made of plexiglass and it is mounted against my classroom window so students can peer inside for an up-close look at the development and early life stages of a bird.
During the springtime debut of my birdhouse, I was always looking inside hoping to find evidence of birds. After repeatedly peeking into the box and seeing it empty, I was thrilled when I finally looked inside and discovered that it was full of earth materials (moss mostly moss and fur) and had chickadee eggs buried deep inside. After a few weeks, the eggs hatched!
Please excuse the early photos (it took several attempts before I figured out the best angle for photos from within my classroom to avoid window glare and flash issues.) Eventually, I was able to capture a few pretty great photos. It's almost comical to watch the development of the birds as they begin to outgrow the nesting box.
(Thanks to the plexiglass, all of these photos were taken from INSIDE my classroom!)

My students and I couldn't get enough of these little birds. We were always peeking into the nest. There is an educational value in hatching eggs in a classroom incubator, but this experience had WAY more to offer since we were able to watch all the family dynamics as these young birds developed. It was a truly touching and exciting time in our classroom.
If you're interested in having a nesting box for your classroom, you'll need to do some research.First of all, find out what kinds of birds nest in your area. Bluebirds are common in my part of Michigan (hence the bluebird nesting box.) It was just a bit of a fluke that chickadees also like the same type of homes as bluebirds. You will also need to investigate what appropriate nesting boxes for the birds in your areas. I was shocked to discover that birds can be very fussy about their housing dimensions. Even the size of the entrance hole is important. I cannot emphasize the value of bird research enough.
Once you do your research, you'll need to create a nice, inviting environment for the birds. Here are some general guidelines:
Build your birdhouse, then get it outside as soon as possible.Birds hate fresh wood. Their home should look and feel as natural as possible. Avoid painting and decorating your birdhouse. It's a waste of time. Build it, then let it sit in the sun, rain, wind, snow, and everything else so it has plenty of time to weather. Chickadees begin hunting for homes during the winter so the sooner you get your birdhouse outdoors, the better.
Birds won't volunteer to have people staring into their homes all the time. You don't want to scare them away. I taped a dark piece of felt to the window. Lifting the felt allowed the students to peek inside of the birdhouse, and the dark color prevented excessive amounts of classroom light from entering the birdhouse. The darkness provided the birds with a sense of security which encouraged nesting.
Beware of predators.
I was very fortunate to have a tall hedge in front of my classroom windows at the time. The hedge was essential to the security of the birds. It was tall enough to block view of the birdhouse an provided plenty of space for the chickadees and other birds to hop around and find food. Sadly, the hedge removed shortly after the chickadees left the nest. The bushes were definitely an eyesore and the school looks so much better without the hedge, but sadly, the chickadees have not returned since the hedge was torn out. Now the birdhouse is too exposed for predators.

Also beware of wasps. Since the success of my birdhouse, a few others have been added around the school. We've noticed that wasps occasionally come to make a cozy home for themselves as well. Just keep an eye on it and find a brave soul remove any nests made by these pests.
No more hedge outside my classroom...
