Swallows

 I checked four boxes around where the single flock of Bluebirds was raised. No new nest was found.

I had worried about the fate of several nests in the burn area (see previous post). Checked two likely boxes. It looks like the swallow chicks survived. They may have been eggs during the burn, so there may be no smoke risk.

Swallows are finishing up nesting. These birds are ready to go in a week. You can see full body feathers and quite alert birds, usually 5-7. 

They are not ready to fly but are flapping wings. You can see the tip of the wing feather going from pin feather to full feather.
