- It's roosting time at the Chimney Swift nest. As usual, there are several adults resting in the shaft. One repeatedly flies hard into the wall making a loud thump each time. This action was followed by a second adult swift moving from that wall to a position closer to the nest. The young are almost ready to leave their nest for the first time.
