The five bluebird babies are all doing just dandy- eyes are wide open and pinfeathers have poked their way out. The mouths are huge. A bump against the birdhouse pole or a wiggling finger above them sets them screaming and makes their long necks come reaching up as high as they can! (See the hole right below the eye on the bird on the left? That's his ear.)
This one of the smaller babies got shoved to the edge of the nest with an arm and a leg hanging out. He flapped his way back in, displaying his three rows of blue pins. The new feathers are starting to come out in little white tufts.
As you can see, the feathers don't sprout all over. Rather they grow from patches and when they are full-grown will be fluffy enough to cover the whole bird.
I love baby bluebirds.
