These bluebirds are all about raising babies! No sooner is one brood fledged until Mama begins building another nest. I always remove used nests and hose out the box between broods. No need to risk mites or other parasites. I think this is one of the reasons the bluebirds return brood after brood and season after season. In the wild, they often change nest sites after one brood.

When we returned from a five-week trip, evidence indicated all five eggs of the last brood hatched and fledged. I’ve seen three of the young in the back yard following Daddy around while Mama is starting another nest and laying eggs. By the time a bluebird is a month old, it’s fairly self-sufficient.

Bluebirds wing-wave as a form of communication. I don’t fully understand it, even though Daddy wing-waves and chatters to me. I’ve read that it is used in courtship, but is much more than this. The bluebirds seem to do it constantly to communicate with one another.
Hopefully all of the young are still alive. But when a species like our beloved bluebirds needs to produce multiple broodings for the species to persist, we know they have a high mortality rate. In the wild about 55-84% of Eastern bluebird nesting attempts fail (Radunzel et al 1997.)
Mama has already build a nest and deposited four little blue eggs. Today she added a fifth egg. Only one time have we had six. Our beautiful world, pass it on.
Total bluebirds fledged from this site is 91.
