Migration over Florida


Birds were on the move over the Sunshine State last night, although densities were still lacking over the southeast as a whole.
Here’s the radar from sunset last night through 5:00am 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.

As you can see from the regional composite, another frontal boundary was sitting across Florida last night. Migration north of the boundary far exceeded that to the south of it, yet Florida as a whole did experience migration throughout the night. The south Florida radars indicate that a small push of migrants did make it into the SE part of the state, as well as another small movement of birds made it off the mainland and into the Keys, and another one from the mainland/Keys into the Caribbean. Whether this will be noticeable on the ground is another story. I would suspect that only the regular migrant traps should show some new birds, and even there birds will be pretty well dispersed. I look forward to your reports from the field!

Good Birding! 🙂


  1. A small but noticeable movement today at Cape Florida. We banded 45 birds with all the nets open. First real push of OVEN with numbers of REVI, BTBW, AMRE and WEWA. Bobolink morning flight was pretty good.
