There is at least one baby bird in the barn swallow's nest. The adults fuss at me and dive at me every time I go down to the barn but I am so happy to see them again this year. The eat insects so they are always a welcome site here.
June 4 update:
I saw a little bird sitting in the barn today and it flew just as I started to walk into the barn. I think it was one of the baby barn swallows.
