Go West Young Bird

Wow, do those east winds blow.

All the Florida radars were showing strong migration echoes last night, and all of them had some degree of east–>west movement due to the dominant wind direction. The Key West and Miami radars really showed pronounced E–>W flow, with many birds leaving Cuba actually heading into the Gulf, and the birds leaving Miami seeming to head straight for the west coast. Whether these birds would then track north along the west coast, or actually shoot over into the gulf is a mystery to me- but the Tampa radar does show a strong S–>N flow, suggesting that the birds took a turn to stay over land. The latest image at 5:30 shows plenty of birds over the Keys and heading toward the Gulf- so the ones originating over water seem to be sticking to it. Reports from the Tortugas will be interesting today…just to see if these birds keep going throughout the daylight (something that migrants over water do more often than those over land) or put down at first light. West coast locations should see the bulk of the birds today, as they’re getting hit from the south and from the east. If the gulf birds decide to head for land, then Fort Desoto could see new arrivals throughout the day…reports, please! 🙂

Good Birding

  1. Cape Florida had good numbers of Cape Mays, common yellowthroats, black-throated blues and ovenbirds, as well as lesser numbers of a wide variety of other Caribbean migrants that were already onsite at sunrise. We banded 52 new birds today of about 20 species. I was surprised at how many birds were out at Cape Florida today with the east wind blowing everything west, but it had rained in the night a bit. Looking at your radar loop there is a small shower that moves from NE to SW across Key Biscayne around midnight, and intersects a blob of birds that looked like they were coming due west from the Bahamas. I imagine it was this group that put down on our site last night. It’s interesting to see the distinct waves of migrants, presumably arriving from different islands in the Caribbean.

  2. Sudgen Park Naples migrants this morning
    CAPE MAY 1
    BLACKPOLL 10 [both m and f ]
    REDSTART 3 males
    PALM 10
    N. PARULA 1 male

  3. Those winds blowing east to west was great for migrants in the Naples area. I birded three locations in Naples today and had Cedar waxwings one flock of 50+, Blackpolls everywhere, Cape Mays 6, B.T.Blue 6, Prairies 3, a flock of 30 Palms plus more, a few N. Parula’s, A. Redstarts 1 female and 6 males, even had a few Yellowrumps Worm-eating 2, Ovenbird 1, and a Hooded 1. Nice day. Keep those east winds blowing
