We have a pair of Black Capped Chickadees in the birdhouse in my backyard that are currently brooding. One of the pair will stay in the house while the other gets food and when it gets back, it sits on the branch just outside of the birdhouse and whistles. The bird in the house then flies out and the one that whistled flies in. This goes on all day. Anyone else have backyard babies right now?
