Migration over Florida- strong easterlies push birds west


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.

Migration was evident over the Sunshine State last night, although strong easterlies show birds moving towards the west from all radar locations. Birds can also be seen launching into the gulf off of the west coast. I wonder how Fort Desoto, Naples, etc. are doing these days? Anyone?

Good Birding! 🙂


  1. Spent some time in my yard this morning. Had a first of season Merlin fly overhead. Swallow flyover numbers are way down the past week. I was seeing good numbers of them all through August, mostly Barn but a few Northern Rough-winged and Bank. Baltimore Orioles continue here in small but relatively steady numbers. They started showing up two weeks ago and I see them here pretty consistently through April.

  2. This morning around 0530 the radar showed migration being done for the night everywhere except Miami..weird! We went out and had our second biggest day in the fall at Cape Florida, with 115 birds banded. A LOT of redstarts! Balance was usual Carribbean migrants plus a chestnut-sided left over from two days ago and possibly a blackburnian. Summer tanagers on the mainland in Raf’s yard. Interesting thing about today’s flight-it had a greater proportion of adult males than the US Senate. Winds were calm last night on the ground at Cape Florida.
