Migration shutting down as Gustav approaches

Not much to report today, except to wish everyone safe passage during the storm! Gustav has effectively shut down migration over Florida, save for a small push of birds into the northernmost reaches of the state. Here’s the radar from 7:00pm last night through 5:00am this morning.

While the radar is always impressive when a cyclone comes across, it doesn’t take much to also notice that migration is conspicuously absent. Winds are steady and southerly right now, and birds are staying put. That was NOT the case for the rest of the country (east of the Mississippi, at least) where migration was hot and heavy and headed for Florida. It’ll be Monday night before we see any significant push of nocturnal migrants over the Sunshine state… but at least you can see them getting closer. I’m sure some of you will find some interesting storm birds before then, so I’ll be scanning the Florida bird lists regularly to keep track.

SAFE Birding!
