There is little doubt that the clear blue winter skies encouraged the Eastern Bluebirds to begin spring house cleaning.
I first thought that the bluebirds were building nest but after observing them for a little while I learned quite the opposite for they were arriving at the nest with nothing and departing carrying nesting debris.
Earlier this week I posted photographs of the pair sitting in the bird box opening. One commenter (anonymous) mentioned the entrance hole appeared large for a standard bluebird box. The comment was spot on, the box they are using is constructed for much larger birds however the bluebirds have lain claim. I plan to continue checking on it occasionally to see if they can keep possession throughout the nesting season.
