What Jeff heard matches almost exactly in composition what I heard along Delaware Bay 10 miles north of Cape May from 5 to 6 a.m., although when I averaged call numbers for the hour it came out to 5-6/minute for the entire time. There were spurts of much more calling. I also heard 7 American Bitterns, Gray-cheekeds, the first few Hermit Thrushes of fall, and a few other things.
Does anyone use, or is anyone aware of, a scale turning calls-per-minute into qualitative terms like light, moderate, and heavy migration? This would be site-specific, of course, but I'm curious what other people consider a heavy migration night.
