Possible Nature Study topic: Chickadee Nest

I was skimming the Handbook of Nature Study for a topic that I know I can do this time of year and is found near the church building where my co-op meets.  My mom recommended birds, and I remembered that some chickadees had nested in our bird box last year, and the Audubon society recommends cleaning out the nest boxes before earnest Spring to guard against insect pests.

I thought our box was only a backup house, but there were egg shells in the little nest! 

It came free with a trowel, I got it safe in a shoe box to transport to class.  Hopefully we can observe some birds as well on Friday!

I think the white fluff on top is scraps of the thinsulate that I lined my cloak with when I needed a warmer maternity cloak.  The bottom layer is moss, then they used down.
