Peter reports nest building at Bridges 1 and 3. He submitted data sheets for both.
“In summary, I visited 4 sites. In about 10 minutes each, I saw nothing at Main Street and Hersey Street. However, at Bridge 3, I saw busy nest building by the banded male from bridge 3 last year, as well as an unbanded female. The reverse was true at Bridge 1, with nest building by the banded female from Hersey Street last year, and an unbanded male. ”
