Bluebirds! Season 7. Episode 5. Wins and Losses

Tree Swallows, Charles River Peninsula, Needham, MA

June, already. And a series of cold wet days that made me worried about nesting boxes. For good reason--the chicks in box 4 didn't make it. But everything else is fine.

Tree Swallow, Box 7

I was particularly happy to see tree swallows on box 7. That had been a house sparrow nest since the beginning of the season.

Every week I removed the eggs. It took a long time for the sparrows to give up.

It's a late start for tree swallows but there's still hope.

Box 8

I think I might have to bring the clippers with me next week.
