Eggciting surprise

Nestled in the corner of our wood stack covering is a small nest made of tiny branches, moss, straw, and a few feathers. Mountain Man discovered it when a bird whizzed in front of him as he walked by. When I went out to find it, the bird flew off before I could get close enough to see what it was. I tried again later, sneaking around the backside of the stack, but it never showed up. I hope we haven't scared it off completely! I didn't want to disturb the nest, so I held my camera up over it and this is what was in it: 4 sweet little white eggs with brown spots.

I think these are chickadee eggs. Aren't they so cute?!
