There were no large kettles yesterday (August 26) at Chestnut Ridge as there were on Wednesday, but the tally was certainly greater: ~183 Common Nighthawk. Only 31 of those were counted before 16:00 EST; the majority were spotted between 16:00 to 17:30. Most of the flocks we saw were northbound. In the last minutes of our count, however, some began exiting from view to the south (and, to a lesser degree, to the west), so I cannot rule out that a couple of these birds were double-counted.
