Heavy migration across Florida

Birds were clearly on the move into and out of Florida last night. Here’s the radar from 7:00pm last night through 5:00am this morning.

Heavy migration into North Florida took a southwest trajectory, indicating large numbers of birds entering the Big Bend region of the state early this morning. The rest of the panhandle showed moderate to heavy migration into and out of the area, but the Big Bend region should see the best densities of the northwest coastal region today. Further south birds took a more N->S trajectory, with heavy migration apparent along both coasts. Expect Fort Desoto as well as Hugh Taylor Birch and Cape Florida to be hopping this morning. The Keys, as well, should see plenty of action today as birds could be seen entering them from both sides of the peninsula.

Good Birding,

  2. The radar looked promising at 0515 this morning but we didn’t have huge numbers at Cape Florida first thing this morning. Definently a turnover since yesterday with BWWA, MYWA and PIWA among others seen. But….between about 1100 and 1230 birds started pouring into the area; mostly warblers. We ended up banding 227 birds today; a Cape Florida record! (we’ve been banding since 2002) Most were BTBW; they were 130 of the captures. The balance was AMRE, BAWW, MAWA, NOPA, GRCA with a few CMWA and a FOS EAPH. We heard lots of buntings but only caught one INBU.

    Today’s theory: migration was shifted east due to W winds overnight (they were 10-15 kts NW at sunrise) so the regular coastal Atlantic migrants (the Caribbean bound birds) got displaced way out over the ocean and it took them until near noon to make their way back to shore to our stopover site. We banded maybe 10 BTBW’s before 1100 and they’re very catchable so if they were there earlier, we would’ve known.

    It was a good old fashioned fallout. Whoo-eeeh!! Thanks to Robin, Angel & Mariel for making our record day possible.

  3. Holy fallout, Bander Woman you rocked! David you were definitely right about the Cape hopping, there were hundreds of birds throughout the park today. It was AWESOME! We had a 21 WARBLER DAY including BLWA, TEWA, OCWA, CSWA, MAWA, BWWA, BBWA, HOWA! Raptors were seen all about OSPR, NOHA, SSHA COHA, BWHA, STHA, AMKE, MERL, PEFA and a beautiful juvenile MIKI flyover! There were several Swallows including NRWS, BANS and BARS. In addition there were a small amount but variety of Thrushes and Buntings along with a real nice Rose-breasted Grosbeak.
    Thanks for posting the radar! We should be up and running real soon, sorry about the delay we have been working seven days a week.
    Bander Woman, Bander Woman… 🙂
