Exodus out of Jersey, while some birds stick around

Last night conditions for migration deteriorated over most of the Mid-Atlantic, while the Northeast experienced a much more conducive atmosphere. Here’s the radar from sunset last night through 5:00am this morning.

As you can see from the regional composite, there was a moderate migration out of central and northern New Jersey, and across the northeastern states. Very little movement was evident across the southern half of the state or anywhere to our south, with a small number of birds entering Pennsylvania from VA/Maryland.

Without a large influx of new birds, I would expect numbers to have decreased across the region, although these types of light movements following a large flight can result in interesting patterns on the ground. First, we could see the birds that came in two nights ago moving into more optimal habitat. If you have a local patch that tends to do better one or two days after a frontal passage, you might want to give it a check today. Second, the birds that were moving out of New Jersey were heading for Long Island, NY via Sandy Hook. That bodes well for another good day (with new species possible) out at The Hook. The buoy off of SH is reading light west winds, which further supports that as a good choice.

Good Birding


One response to “Exodus out of Jersey, while some birds stick around”

  1. Tarkiln Pond – and Peaslee WMA – Cumberland and Cape May counties.


    Most of the breeders were around Belleplain this morning. The Tarkiln Pond area and Peaslee WMA. I thought average numbers. Those birds listed above were the only migrants today. Very foggy this morning and then cloudy. Birds didn’t get active until 9:00AM or so. Strange.
