More birds leaving Florida


More birds left Florida last night in a similar pattern as the night before. The trajectory was ESE–>WNW in the southern part of the state, changing to more S–>N further upstate and into the panhandle. This pattern is being driven by a low pressure system over the Great Lakes, which will strengthen and move eastward through the weekend. Coupled with high pressure off the east coast of Florida, unfortunately this promises to strengthen the easterly flow across the Sunshine State and force birds originating in the Caribbean over to the west coast (of Florida). The opportunity for Trans-Gulf migrants making landfall in Florida is quite low through the weekend and into the early part of next week. 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.

You can see that there was no apparent migration out of Cuba last night, and only a very little pulse of birds arriving via the Caribbean. The majority of movement was an exodus of birds out of the state along the Central and Mississippi flyways.

Good Birding
