About 170 mixed swallows feeding over the water at the Hinsdale Setbacks today. I would guess that they roosted overnight in the reedbed. Funnily, most (about 70%) were trees but the remainder were banks. Seems odd to see this many bank swallows together in a flock this early. According to K&F, postbreeding flocking of tree swallow begins in mid July. Looks like it is happening about 2 weeks early this year.
