10 birds fledged since last time

I checked the three boxes that had nestlings last time. All three were empty (of birds). One had two failed eggs, so that box had only 2 nestlings, I had guessed 3 at some point. So my rough count of Bluebirds fledged is 23 for this year.

I did not expect to see much of the birds. At that early hour, only one of the parents was seen in a tree nearby. Nobody was begging for food. In other boxes, a few wrens are nesting. I found one with eggs.

Other places I have seen the young bluebirds with the parents, making very slight calls, no real song from any of the  group. And begging for food as well:
