Seismic wave of migrants engulfs Florida and Caribbean


I can tell you right now, that the internet search engines are going to have a field day with the title of this post…the question is whether most of the traffic will be bird-related or not. In case you didn’t hear me riding around on my horse last night, yelling “THE BIRDIES ARE COMING! THE BIRDIES ARE COMING!”…here’s the radar from sunset last night through sunrise 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.

Holy Cow…I wish I was in Key West or the Dry Tortugas!
But seriously, this was by far the heaviest migration over Florida yet this Fall, with the radars showing extremely high densities of birds moving across the state in a NNW –> SSE direction. All migratory hotspots will be birdy today, with many locations experiencing very high densities of birds. Because there was no weather to bring birds down, the best locations will be along the southeast coast and the Keys, with lower densities at inland sites.

Good Birding! 🙂


  1. Very odd. Lake City’s Alligator Lake was hopping yesterday, but in the wake of last night’s “seismic wave” it was dead this morning. I visited a park in Gainesville and found a few birds – a couple Red-eyeds, a few White-eyeds, a Yellow-billed Cuckoo – but there was no sign of a major influx.

  2. Whatever the heck was on early AM Miami radar did not land in Cape Florida. Banding was slow with small quantity and diversity. A mild surge of Common Yellowthroats and swallows were only newcomers. Birds banded yesterday were fat and fit, reason for them to leave with clear weather. Today Bryant Roberts dug up Blackburnian, Chestnut-sided and Blue-winged — unfortunately away from the banding area. Did they keep going this morning or was the light blue something besides birds?

  3. Here is my tally of migrants seen today:

    American Kestrel –
    Merlin – 2
    Peregrine Falcon – 1
    White-crowned Pigeon – 1

  4. It’s huge again tonight (1030PM Fri Sept 28) across the entire Southeast but dwindling down the peninsula. A dry front is entering the north part of the state. We’ll see what tomorrow brings…hopefully something interesting on my personal last day banding until Oct 18 when most of migration will be over. Liz, Robin and Nancy will carry the torch (or pliers or whatever)

  5. Friday was very slow here in the Orlando area. Maitland Community Park had only a handful of common migrants.
