More migration, this time heading SW


Migration last night looked very similar to yesterday, except that the front was stalled a little further south, and the movement into the state was more NE–>SW. Here’s the radar from sunset last night through 6:00am this morning.

Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.

See yesterday’s post for a general analysis. Again, the highest concentrations of migrants will be along the frontal boundary; so if that’s where you are, grab a raincoat and go birding. West coast locations from Fort Desoto northward will also be very productive this morning. Again there was a noticeable push of birds into Southeast Florida ahead of the front. Given the lack of birds at Cape Florida yesterday it’s possible that these are not passerines, or that they are landing further inland than expected.
No birds were seen heading south out of the Everglades or the Florida Keys.

Good Birding! 🙂

  1. A little bit more around today but still nothing like what is behind the front.
    We banded 15 new including 2 Gray-cheeked thrushes and 3 Tennessee warblers, part of a posse of 5 or 6 that settled out in a fruiting ficus. Weather is very warm and humid; it may as well be August still. We need a front to get all the way down here and blow us, like, a Golden-crowned kinglet or something.
