The winds over southern New Jersey last night were out of the ENE, while most of the region to our west was under more easterly, or southeasterly flow. That seems to have been the deciding factor in where migration occurred last night, and where it didn’t. Here’s the radar from sunset last night through 5:00am this morning.

As you can see, the heaviest migration occurred over the greater New York state (regional composite) with little movement along the east coast, including Manhattan and Long Island. For New Jersey, a moderate push could be seen leaving the northern half of the state, while the south was relatively quiet. A nice pulse of birds were also evident heading north out of the Chesapeake Bay and Delmarva Peninsula, but all of this movement appeared to be heading due north, and bypassing NJ altogether.

Expect little in terms of migration density across the region… with Garret Mountain still holding more migrants relative to other locations.

Good Birding
