Round two …

nestI’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 IMG_4287 ldsecond 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.

IMG_4299 ldIn general northern bluebirds lay larger clutches and southern bluebirds have more broods.  All a part of Nature’s scheme to assure that bluebirds survive as a species.

Right now we are just looking forward to getting a second brood off on the red dirt hill.

    Mama is busy again this morning. Really getting into this nest building. Two of the babies were on the roof next door, but never came into the yard for good pics. Had a Black-chinned Hummingbird in the yard, kinda rare for central OK. Also had a Little Blue Heron on one of the ponds, brings my total to 156 species for my neighborhood.

    Love this! I live in NH and as of yet, no bluebirds in my house! Last year it was June before they nested! Thank you for the updates and for keeping us a part of this natural beauty!
