Another huge night of migration

Heavy migration over the Sunshine State last night will mean good birding conditions at migrant traps this morning. Here’s the radar from 7:00pm last night through 5:00am this morning.

Just look at the regional composite… it’s lit up like Christmas! North winds over the northern half of the state have resulted in hot and heavy migration into Florida, with migrants apparently dispersed across the entire landscape. Moving south, though, winds appear to have been out of the northwest, which seems to have concentrated birds along the east-central and southeast coasts. Coastal hotspots from Fort Pierce down to Key Largo should see some excellent birding conditions this morning. That includes Cape Florida, of course. Also, the flight from FL to Cuba was awesome as well… which you can see on the Key West radar.

Good Birding,

  1. I don’t think I have ever heard so many SWTH flight calls in 8 years of living in So Fla as I did this morning, both at my house in South Dade and at Cape Florida. Continual stream of calling birds in the hours before sunrise. We were expecting a really big day numbers wise, but it was not to be. 73 new birds of 20 species, so it was not boring by any means, just not massive on the ground. The weather was so nice the hundreds of SWTH probably could land where they wanted and chose not to go to Cape Florida, although we banded more than usual. Rain last night intercepting this flight would’ve been epic!

    Those green blobs on radar were a lot of WPWA as well as SWTH, because it instantly looks like winter now with them everywhere. We banded until 3 PM and had an interesting turnover in species being seen and captured about midday, with the thrushes apparently napping or lurking quietly out of view and small warblers (specifically AMRE & TEWA) taking over for the rest of the afternoon. The most interesting captures were ACFL, YTVI, YTWA and a 15-gram TEWA. Dude was so fat I thought he was a blackpoll in the net.

    Happy first full day of life CW!

  2. Swainson’s Thrushes were everywhere today! Here is the run down, 8:55-10:00am at Bill Sadowski:
