Minor exodus out of South Florida

Sorry about the late post… I fought the alarm, but the alarm won.
Not much going on “bird wise” last night, except for a small movement over South Florida and into the Florida Keys. Here’s the radar from 7:00pm last night through 5:00am this morning.

If you just look at the regional composite it appears as if birds were migrating over most of the state last night. A closer look at these individual radars, though, indicates little to no southbound movement, with a few exceptions. The biggest exception is the Miami radar, which does show a moderate level of consistent southbound migration through the night and early morning. The other is the Key West radar, which shows a small pulse of birds from the mainland to the upper Keys, and a smaller movement from the Keys into the Florida Straits. Neither of these movements was very large, and therefore will be difficult to discern on the ground, except possibly at some locations in the upper Keys where habitat is limited and therefore birds will be concentrated. As always I look forward to your observation.

Good Birding,

David

  1. off topic…as we all know mockingbirds are quite loud during nesting season, singing at the top of their lungs. Today my resident mocker, who is here year around, has spent the afternoon on the wires out back sort of whispering to himself. He’s run through a large repertoire of songs and calls a very low volume, a bit like someone singing quietly under their breath while working in the yard. This bird distinguishes between harmless residents like me, and possibly threatening outsiders like the mailman, who gets pecked. He knows which neighborhood cats are bird hunters and chases them relentlessly, while he ignores my four flabby housecats, who are intimidated by the outdoors and never venture off the deck.
    Smart fellow!

  2. Hey David
    Migration seems to have picked up down here in the MIA. A late afternoon stop at Barnes yesterday produced a beautiful Cerulean Warbler! Awesome! We had a good number of birds present at the park. We walked the trail to the boardwalk a picked up a couple of migrants mostly AMRE but on our way back we found a nice group of Warblers. In just one tree over the butterfly garden we had 5 species in good numbers. Our quick one hour stop yielded the following birds.
    The List:

    6 Blue-gray Gnatcatcher
    1 Northern Parula
    3 Yellow-throated Warbler
    1 Prairie Warbler
    1 CERULEAN WARBLER
    5 Black-and-white Warbler
    4 Worm-eating Warbler
    1 Ovenbird
    1 Louisiana Waterthrush
    1 Summer Tanager
    Today Rafael and Toe found four Hooded Warblers at Matheson along with 3 Yellow-throated Vireo, both Waterthrush species and a quiet Traill’s Empid. All of the above was seen as well.
    Thanks again for providing such a great tool for us down here, you ROCK!!!
