two cuts of calls from hundreds of birds at their communal roost at dawn, with various small groups leaving, and then a cut of calls from a couple of different small groups of birds flying away from a large communal roost, after most of the birds had already departed.

*High count; three estimates by hundreds: 3600, 3800, 4100, so we went with the middle count. Quite a spectacle!
