Big migration over Florida

South Florida received another good push of migrants out of Cuba last night and into this morning. Here’s the radar covering that period up until 5:30am today.

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.

A front pushing into north Florida effectively shut down some heavy migration in that region of the state, especially the area in the northeast corner. Based on this observation, it’s possible that some localized fallout conditions exist in the Jacksonville area this morning. Otherwise migration over Florida was moderate to heavy and occurred relatively unimpeded by weather. All radars along the peninsula showed signs of migration last night, and a good push of new birds entered the Key West and Miami radars early this morning. Aside from the northeast corner, birding conditions this morning should be best at tried and true spring migrant traps given the widespread nature of the migration event.

Good Birding

  1. David, Miami radar showed the echo of a large ring of birds exiting the vicinity of Loxahatchee NWR this morning at about 7:00 AM EDT. I posted the loop on my blog, for your information. I wonder if anyone who is near that area ( or WCA-3, which also has produced a similar “donut”) at dawn could determine the species: waders, blackbirds, swallows, or whatever?



  2. Hi David! Nothing much in the way of migrants at Ft DeSoto today. A few warbler species, Indigo Buntings, and a male Bobolink were the highlights. I was told that the Sanibel Lighthouse area was also slow today, Sunday 13 April.

    Saturday I was attending the FL Ornithological Society spring meeting (Wasn’t the same as the fall meeting w/o your esteemed presence this time!) and found it to be very quiet along the Gulf coast in Crystal River as well.

  3. David,
    I was birding in Cedar Key, Fl all day Sunday. An itsy bitsy fallout occured late afternoon in the cemetery, consisting of 9 Scarlet Tanagers, 3 Summer Tanagers, several Indigo Buntings & 3 Orchard Orioles. In other locations I found more Scarlet Tanagers, Eastern Kingbirds, a Cape May and an American Redstart.

    Great observation. I wonder if you could contact a ranger at LOX and see if they can help pinpoint the species composition? It would be very interesting to know for sure.


    Thanks so much for your ground-truthing!
