Chris, In costal Cape May a good Morning Flight can produce a dozen or so birds, mostly by themselves, sometimes with Boblinks. A hundred or more should be heard passing Cape May in a fall season if the observer is listening at night too. They're detected here until Nov with one or two wintering at a feeder with House Sparrows.
