Four Birds Left Box

 I was hoping to get another photo of the bluebirds, more developed. if you look at the last photo, you can see that the front bird has pinfeathers, and the back birds is more feathered. So very likely at least three birds were able to fly when they left. It was still very early, they could have stayed several more days.

If you look at last year, for example, the birds should have very little or no yellow on the bill when they leave the box:

SWALLOWS

About half the sallows have chicks like this (asleep, can't see bills), well feathered. Half have just hatched chicks or eggs. I did not check very many.

There is not much to monitor, so I don't know if we are done or if there are more bluebirds to come. Next check will be in a week.
