Cold front triggers influx into N. Fla.; little movement further south

The latest cold front to reach the region has begun to trigger heavy migration over North Florida. Here’s the radar from 7:00pm last night through 5:00am this morning.

As of 5:00am this morning, the latest cold front appears to be draped over Central Florida, resulting in optimal migration conditions to the north of the front, and sub-optimal conditions to the south. Migration was heavy into northern Florida last night with most birds following the wind on a NNE->SSW trajectory. Meanwhile, migration over southern Florida was minimal, with most birds moving against the easterly winds on a more N->S trajectory. Fall migrant hotspots should be birdy for the northern half of the state, while minimal changes in birding conditions are expected for the south. Little-to-no birds could be seen leaving Florida for the Caribbean, so any birds seen heading south over Miami last night should be piling up in the Upper Keys.

Good Birding,

David

  1. Yep again — slow but steady today with 21 banded, including record-breaking Chuck’s #11 for the season, FOS Maggie and another Great Crested adult. Couldn’t buy a WEWA today and we only need 3 more to break the 2006 record.

  2. Right on — most of the birds today at Matheson Hammock after a quick 40 minute session of speed birding turned out to be pretty much the same of what we had on Saturday’s NAMC, probably even the same individuals, in terms of species composition and densities:

    Merlin
    Chuck-will’s-widow
    Ruby-throated Hummingbird (4)
    Yellow-throated Vireo
    White-eyed Vireo
    Blue-gray Gnatcatcher (7)
    Northern Parula
    Black-throated Blue Warbler (3)
    Common Yellowthroat
    Worm-eating Warbler
    Ovenbird (7)

    The only birds I got today that we didn’t have on the NAMC were White-eyed Vireo and Chuck-will’s-widow.

  3. Hey D La P,

    This morning we birded the area behind the Ryder Business building @ FIU and the surrounding areas on campus we found the following warblers:

    Cape May Warbler
    Black-throated Blue Warbler
    Northern Parula
    Prairie Warbler
    American Redstart
    Yellow-throated Warbler
    Black-and-white Warbler
    Chestnut-sided Warbler
    Blue Gray Gnatcatcher

    Yellow-throated Vireo

    and a Cooper’s Hawk looking for a breakfast meal. (watch out EUDO’s and MODO’s)

    Nature is awesome
