What kind of birds are living in all these cool houses?
So far, just a chickadee nest pre-egg. But there should be swallows, wrens, and hopefully bluebirds soon! And the killdeer nest (on the ground--not posted) does have eggs and one has pipped (tiny hole). I heard it peep from within the egg (such a proud non-parent). I'm resisting the urge to sit next to it as it hatches. I should give it an hour or two I guess.
