Nice influx of new birds into Florida

Northwest winds across northern Florida triggered some heavy migration into the Sunshine State last night, while easterly winds over south Florida pushed moderate levels of migrants inland. Last night also marked another departure from the Keys towards Cuba, a sure sign that fall migration is again underway. Here’s the radar from 7:00pm last night through 5:00am this morning.

Looking at the southeast composite you can really see the heavy migration all along the northern border of Florida. Most of these birds were heading SSE, being brought in on a northwesterly tailwind. Winds turned northeasterly, and eventually easterly, as one moved south through the state (and was due east in Miami at 5:00am). This change in wind direction is reflected in a decrease in migration activity as the Miami and Key West radars showed only light (Key West) to moderate (Miami) migration levels. With easterly winds over South Florida, expect the best birding conditions to be inland or on the west coast. Given the push into the Keys early this morning, Key West should see some good birds at first light. The best bet, though, appears to be north Florida, where migrant hotspots from the Panhandle to Jacksonville should be seeing good numbers and diversity this morning. As always, I look forward to hearing about your experiences in the field!

Good Birding,

  1. Been negligent in posting Cape Florida results.
    Banding about 10 birds a day the last 4 days, except Liz had 22 on the 27th. Today’s highlight was a Traill’s flycatcher. Birds have been a mix of classic Caribbean migrants: WEWA, BAWW, AMRE, OVEN, NOPA, NOWA plus a couple of PROW and some early BTBW’s. REVI’s around but not being caught.
