I was so excited to see bluebirds checking out the nest box I put up over a year ago. We have a lot of bluebirds in the neighborhood but they only stop in my backyard for a second and are very skittish. My neighbor several homes down from us has 2 bluebird boxes in his backyard and he’s lived here a long time so I think they are pretty established over there. There were young ones bouncing around the yard this spring so I’m assuming they nested in his box. Finally, in early November I caught them going in and out of my box for several hours. There were at least 4 of them and they also stopped at the feeder and bird bath. The next day I went outside and took a peek in the box and there was a nest in there but no birds or eggs. Maybe they were building it early (like several months early)?
