After receiving Peter’s reports I stopped by both nest sites in the afternoon.
At Hersey St. the female was in the nest box and she was brooding 2 nestlings from what I could see when viewing the box with binoculars from downstream. They must have hatched sometime in the last week since Donna’s note on May 30th.
At Bridge 3 I saw both adults near the bridge and watched the female fly up to the box and stay. She was not carrying food . The male stood guard on one of the rocks below and preened. Something may have happened to delay the hatching of their second brood. Questions….
