While not as drastic as I had originally anticipated, birds do appear to have moved through the mid-Atlantic region in a manner that would suggest an overall net loss in density. Here’s the radar from 7:00pm last night through 5:00am this morning.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

The regional composite probably shows it best, where you can see the migration signals over most of NY and PA were quite weak (due to southerly winds), suggesting that the bulk of migration took place over extreme southeastern NY and all of NJ. While this could still (and I expect it did) result in good birding in southern NJ, the overall effect for the rest of the state will be lower densities. This might be a good time to hit Cape May, both because it’s one of the few places birds will still be concentrated, and because of the Northern Wheatear that was discovered there yesterday.

Good Birding
