A New Wave Of Nocturnal Migrants

This is the radar from 5:00pm last night to 10:00am this morning.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

On radar last night migrants were headed for the states as can be seen on the KW and MIA radars. Key West radar picked up a group of returns coming in during the night and heading over and into the upper keys and southern Miami-Dade County. Your best chances of finding migrants today would be at your westernmost migrant traps such as ENP, Luccy Hammock/Annex, Castellow Hammock, KIH, Chekika etc. If you are birding the Keys check out traps along the chain on keys as they all can have a great variety of birds. ENP is very large an therefore will make it harder top pinpoint migrants as they can be spread along the wide expanse of the park.
Along the southwest coast we picked up returns heading towards the Sanibel coast and the Ft. Myers area. We would love to hear from some west coast birders that may be able to confirm whether or not birds came in today.
Further up the west coast your best chances of seeing any concentrations would be from Sarasota to the Cedar Key area. Birds were definitely moving into the region last night and this morning. Although the southeastern composite radar loop was in an out all night we were able to get an overview of what was happening over the northern portions of the state.
Jacksonville radar showed the heaviest densities of migrants flying overhead, at one point of the night you should have been able to hear thousands of flight calls in a short period of time. Birds may be scarce around the area as with a south wind migrants would have made it passed the area and into Georgia.

Now it is your turn, please pass by and post your migrant sightings. The site is only as good as you all make it, your sightings are invaluable for both the birds and for learning more about radar migration.

  1. Not too many migratory birds at Ft DeSoto yesterday. Biggest highlight were the Cedar Waxwings still hanging around. The Prothonotary Warblers were still in the area. Did not see any additional new birds. The Hooded Warblers are gone and I was surprised not to see one single Ruby-throated Hummingbird. I will out birding today and tomorrow and will report findings. Hoping birds come in with the next front.

  2. Thanks for the report Gail, with optimal winds we expected the Hooded Warblers to be out of there as of early this week. Birds are on the way and with a front that may halt migration north we may get lucky and have these migrants wait for better flying conditions. If the doors to the north are closed they will just pile up in Florida!
