Strange spring of low activity

Swallow nesting is way down in the South end, normal by Nature Center. Bluebirds seemed to have finished nesting for now, with only 11 chicks soon to be fledged. No new eggs were found. Box 4 team is ready to fledge with 7 days.

Box 6 four chicks fledged, one egg never hatched. Box 11 has one fully grown bird, it only had two.

I have a feeling more bluebirds will appear in June, but nothing is happening now. There was some ant activity, but not in nests with bluebirds. I will have to take care of the ants in a week or so. The one ant colony was in a wet spot and sought the box as dry ground.
