Eastern Bluebirds Visiting Nest Boxes

 

Eastern bluebirds  have already been seen checking out nest boxes – behavior that usually isn’t observed for another month or so.   Interestingly, even though most people religiously clean out their bluebird boxes every year prior to the nesting season, experiments show that bluebirds prefer nesting boxes containing old nests.  While breeding has not yet begun, it won’t be long before males will be trying to attract females to their nest site by carrying material in and out of the hole, perching, and fluttering their wings.  After the males choose the nest site and perform for a mate, the females actually do the hard work of building the nest.
