A Break In The Forcefield

This is the radar from 5:00pm last night to 5:00am this morning.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

A much needed change in conditions triggered a heavy flight over the NE which means more birds are moving south. In the following days we expect the parade of migrants to continue to trickle down until a front comes along and shoves them south.

Last night migration was evident over the state with most of the activity happening over the Jacksonville, Miami and Key West radars. Birds were moving in a general lazy NE—>SW trajectory over many of the radars. The flight appeared to be a short distance flight with most radar stations picking up most of the signals before the hours of 1am. Miami radar recorded birds flying over in a more N—>S direction and showed the signs of a short distance flight. A small influx did come in from the west around the hours of 3am and was picked up on the Miami radar. Key West had some light migration overhead. Early into the evening a small flight out of the Greater Everglades and Miami area headed for the Keys. Velocity radar also picked up a short flight here with signals dying out around 1am. With the densities recorded last night we don’t expect a lot of action but we should welcome new faces. Look for migrants at true-and-tried migrant traps.

In the following days we can expect more birds to be on the move. Last night the Charleston, SC radar was alive with activity. Heavy migration occurred across the entire northeast, edging the birds closer and closer to the peninsula. High pressure set up perfect conditions with NW winds over the region last night. We are waiting on a shift of both winds and weather conditions for a new influx of migrants. Be on the lookout for this weekend’s birding forecast, we will be posting one up soon.

  1. In the Marathon area, Larry McDaniel and I started early, with plenty of misses and about to throw down the towel when at the last moment, as we were returning to Curry Hammock State Park to get onto the hawkwatch, we experienced one such hopeful trickle of migrant warblers. We had to really look for those birds. The species seen/heard included all the regular warblers, highlights:
    Cape May Warbler (fast and tight feeding flocks on the move)
    Magnolia Warbler (brief appearance)
    Tennessee Warbler (incredibly fast look)
    Worm-eating Warbler
    Louisiana Waterthrush (briefly seen, yet heard)
    Black-throated Green Warbler
    and more.

    We had an exciting day at the hawkwatch. Here is a link to the day’s report:

    I hope folks plan on coming down to FKH on Saturday Oct 8. Migration and the banding station – a win win for all!!! See you there.
