I have been monitoring bluebird boxes for over 15 years. I typically check the boxes every 2 weeks to monitor progress, although I don't always end my "season" at the same time of year.
With all that said, the latest I have found a new clutch of eggs (4) was Aug. 11, 2007. I saw 3 nestlings on Aug. 26, 2007. The nest was completely empty on Sep. 9, 2007. Without any infertile eggs or dead nestlings, I assumed all 4 had fledged.
The weirdest one I remember was in 2003. On June 28, I had a box where I could see 4 tree swallow nestlings. On July 12, the swallow nestlings had all fledged and there was a lone bluebird egg in the nest. To my eye, it looked slightly larger than a typical bluebird egg. I returned on July 26 and found 1 bluebird nestling in the box. By August 10th, it had fledged as the box was empty.

A family of 4 bluebirds has returned to my garden, young still asking to be fed - now to my slight dismay in this heat, there are 4 eggs in the box used in June. I've lost nestlings to heat before - what have other people experienced this late, or is this possibly 3rd laying normal? The first eggs in May were duds, second lot fledged 3 or 4 - don't know of course if this is the same family.
