I'm not good at counting birds, but tonight I saw a sight that reminded me of the fall, when chimney swifts flock into the school chimney across from our house in Hudson. At least a hundred were circling, and then making their tight spiral into the chimney as darkness fell (and the thunder rolled). Is this typical behavior this time of year? I thought they paired off and nested separately and then did their mass roosting in the fall.
