I’ve yet to see the babies since they fledged. But, I have to admit I haven’t been tromping the creek bottom looking for them. Previous experience says they are so high up in the trees that a good look or photos aren’t likely anyway. I’ve done my job when they fledge, after that they are pretty much on their own. Still, I expect to see them in the back yard now that the adult birds will be spending more time here.
Mama II and Daddy II have been in the yard more the past couple of days. This morning I saw Mama carry grass into the box. She was really busy for a couple of hours and I got several photos of her bringing in nesting material. As usual, Daddy played the role of building inspector.
The babies fledged on 25 April and now just 12 days later, Mama is getting ready for a second brood. Mortality is high in young birds and multiple broods are a technique bluebirds use to see that the species persists.

The Cornell Lab of Ornithology analyzed data on repeated use of nest boxes from more than 7,000 Eastern Bluebird nesting attempts reported by The Birdhouse Network’s participants from 1998 to 2002. The results, to be published in The Journal of Avian Biology, show that the number of nest attempts per box was 26 percent higher in the South than in the North. The number of nesting attempts per box by Eastern Bluebirds in the southern portion of their range was 26 percent higher than in the northern portion.
Right now we are just looking forward to getting a second brood off on the red dirt hill.
