Nice flight out of Cuba

Southeast flow over Florida set off some good migration last night. Additionally, southerly flow over the Florida Straits resulted in a large flight of birds out of Cuba. Here’s the radar from sunset last night through 5:30am 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.

The heaviest migration last night occurred in the northern third of the state, as winds were south to southwest (panhandle) and the skies were clear. Further south, as winds turned more easterly, migration was evident but only at moderate levels. The real story, though, was the large push out of Cuba on southeasterly winds. These birds began making landfall around 2:00am this morning and continue to do so as of 6:30am. Given the size of the cloud, this morning I would expect new birds to be evident in the Dry Tortugas, in the Keys, and along both southerly coasts of the mainland. Due to the lack of weather, though, birds are not likely to be concentrated in any single area. Choose the best spring migrant trap for this morning’s birding!

As for the Gulf, southeast winds between the Yucatan and the gulf coast favor more westerly states, although the westerly winds over the panhandle could redirect some birds upon making landfall early this afternoon. Keep an eye on the Jackson Audubon bird blog to see how things pan out along the gulf.

Good Birding




  1. David – love the new look & features! I hope and trust that people will take you up on your vision of a national network of radar watchers. It’s a tremendous citizen-science opportunity just waiting to be seized…

    Thanks for all the links, support, etc.
