the front forecast frozen at 6:00 a.m. Zulu, which means 2:00 a.m. EDT 9/15/2015, shows a cold front that passed yesterday, a high pressure system over our region, with pretty much nothing to stop migration from our Cape May "sending zones" of northern NJ, Pennsylvania, New York, and New England." And weather and winds to encourage it.]
And, apart from today, which was insane at least at Higbee Beach WMA in NJ, with over 56,000 birds this morning, over 46,000 of which were warblers (and we're not talking yellow-rumpeds here), and almost all of that in the first hour (!), it's been two weeks since we've had a really serious southbound flight of landbird migrants. They've been trickling, but the pipe has been clogged. There are many birds "in the pipe," and the weather, wind and time of year combine to act like the product known as Drano.
One more thing: tomorrow is September 15. Peak, or maybe past peak by a few days, for neotropical migrants in Cape May.
I really recommend birding tomorrow. What's the worst that could happen? You skip work and go birding?
