I'm not sure what the calling is about. Normally the fledglings return to my back yard a week or so after leaving the box. You'll probably see them again.

My third clutch of three eggs should have hatched on 11 July, so I removed an egg this morning and checked the contents. It's been over 100 degrees every day they have been in the box and egg failure is high in hot weather. The egg had a yolk, but no embryo. Tested the other two with same results, so I removed the nest so Mama won't be inclined to endure the heat of that box any longer.

We are leaving for Santa Fe in the morning, so I won't see the bluebirds for awhile. I hope they don't attempt another nest this season. Just too hot.
