Monday evening, while doing my routine Peregrine monitoring at the Tarentum Bridge (Rt 366) a large flock of migrating common nighthawks appeared drifting upriver (wrong direction - NE) while circling and obviously eating. Best guesstimate would be ~50.
They first appeared ~6:47 PM, moved upriver out of sight then after about 5 min began drifting back downriver in smaller groups, still circling and eating. Whole sighting time was about 10 min.
A first for me - seeing a large group of CONIs on fall migration.
