More migration restricted to the southern tier and coastal New England


National Overview

Was, rinse and repeat yesterday’s synopsis, as the same weather systems are slowly creeping eastward. With a mixed stationary and cold front draped across middle America were seeing moderate to heavy migration up through Texas, the Gulf Coast and Florida and only a small background flight of birds up along the New England coast.

Below are the radar loops from sunset last night through 5:00am this morning

In an attempt to get the radar posted as quickly as possible, I will be publishing “as I go” each morning. Therefore you may see some incomplete posts throughout the early morning hours (5-6am Central; 6-7am Eastern Time). We’ll test out this method for a few weeks and see how well it works… your feedback, of course, is most welcome!

Nothing going on over the Mid Atlantic last night, as conditions are not conducive to migration. Only a little action could be seen to our north as birds used light winds along the New England coast to push up into the extreme northeast. Over New Jersey, though, only the tiniest movement could be seen as birds headed out of the state into eastern New York. Expect little change save for a net loss in the northern half of the state.

Wisconsin (Upper Midwest)

Can you hear the crickets in here? No nocturnal migration evident over Wisconsin last night and any movements that did occur either did so at such low and diffuse numbers and/or at a very low altitude. Small localized movements are expected, but otherwise the Upper Midwest was quiet for another night.

As always, woodcreeper.com depends on YOU to report your sightings and be our ‘eyes on the ground’, so please come back and give us an idea of how we’re doing predicting birding conditions in your neck of the woods.

  1. Just discovered your website via ebird. Would love it if you included Canada in your migration data.

    • Thanks for stopping by Leslie! I’d love to include Canada- but I have barely enough time to do the Upper Midwest AND the Mid Atlantic. We’re almost to the point where we have automated the “download-animate-post” process at which point we will provide the code and infrastructure necessary to anyone who wants to put together a website for their area. If you know someone in Canada who might be interested, please have them contact me! david@woodcreeper.com. Of course, getting Canadian radar data is a little trickier so we’d have to either use US radars near the border, or figure out how to tap into the Canadian system.
      Thanks again!
