Three Bluebird Nests

I dealt with the three mouse nests, discovered a month ago. It takes about a month for the naked babies to grow and be old enough to survive and move on the ground. See the adult mouse and smaller pup in the previous post.

Two nests are perfectly normal, one with one egg, one with four.

All the eggs are near white in all the boxes, but swallows do not have eggs yet (several nests built) and are clearly smaller as well.

The third nest was the odd one. One egg in the nest but two broken eggs on the ground. Swallows may fight for a box but do now break eggs. This is the work o house wrens, which have nested in these boxes at this stretch of the South side last year. They nest more past July than now. But are very possessive of hole nests in their territory.

The North side had the usual swallow nests but only one likely Bluebird nest with no eggs.
