Observation details

First got on one small, sleek swallow with brown above and clean white underparts except for a bold brown breastband, too defined and complete for a juvenile Tree Swallow. The bird was going back and forth around the NE corner. Then a very vocal and apparently agitated Tree Swallow came through flying north, pursuing three Bank Swallows which were showing off their harsh flatulent vocalizations as they went. They streamed overhead too quickly for me to confirm key field marks for all three birds, but before I got bins up they appeared roughly the same size/shape and definitely gave off more of a BANS vibe by more fluttery flight action. While the TRES doubled back, I did not see or hear any more Banks after that.
