In the face of adversity… birds migrate

Well, I must apologize for not posting this sooner… but when I went to sleep last night, the only things showing up on the radar were moving S->N with the wind. Sometime in the middle of the night, though, the wind appears to have slacked and birds took to the sky. Here’s the radar from 7:00pm last night through 5:00am this morning.

While most of Florida has been quite since Fay came on the scene, there was a noticeable pulse of south-flying birds over the state last night with smaller amounts of birds entering and leaving the Florida Keys. While not huge, this movement should be visible on the ground today. Since the surface winds are out of the east, I would thing the more inland locations would fare better, which any migrant traps in the Keys should feel a little more “birdy” this morning. Don’t expect warblers dripping from trees- but instead hope for an unusual “chip” note from within your recently quieted bushes.

Good Birding,

David

  1. It looked like birds went out over the ocean from up near Lauderdale or somewhere last night. Something happened because we had migrants around this morning at Cape FLA; dropping in right at sunrise. Banded 21 birds; about 75% AMRE. Nice change from how dead it was over the weekend.

    What’s going on in Jax? it was bright green last night.

  2. A.D. Barnes Park was noticeably more active this afternoon. In about an hour and a half, I saw Worm-eating Warbler (1), Prairie Warbler (2), American Redstart (4), Northern Parula (5), Black-and-white Warbler (2), Ovenbird (1), Northern Waterthrush (2), and Summer Tanager (1).

    Thank you for continuing with this great project!

  3. Carlos- thanks for the report from AD Barnes, and the comment.

    Michelle-
    Good to hear you had a more productive day. As for Jax, the radar did indicate a good movement over NE Florida, but some of that was “noise” as the velocity suggested only a portion was actually moving south. Anyway, I’m assuming it was just a buildup of migration-ready birds, and the conditions were “acceptable” to some of them… it was pretty cool!

    It’s looking like we’ll see some migration on Wed-Fri nights, although the winds are looking to be out of the east, which is no fun for you. We’ll hope for the best!

    Good Birding
