Migration last night

Moderate to high migration out of Cuba last night, with light migration out of and into Southeast Florida, and increasing levels of migration moving northward. The Panhandle was “ablaze” with migration last night…a good sign for us up north awaiting birds already weeks late! A line of thunderstorms moved over the Keys before daybreak, possibly causing some good birds to “fallout” in the Dry Tortugas and the Keys themselves. It’s hard to tell whether the rain was strong enough to do so, so some ground truthing is in order. More birds appear to have left Southeast Florida than appear to have arrived, although it looks like the westerlies pushed the incoming birds toward the coast. Excellent birding conditions are possible for Southeast Florida today. Fort Desoto and the west coast is experiencing NW winds, so anything moving over the southeastern gulf should make landfall here, making this migrant trap a good bet for today as well. Any and all reports are encouraged.

Good Birding

  1. Noted 61 species today at Fort DeSoto, 68 including the duck pond just to the north. Orioles, warblers, grosbeaks, tanagers and buntings, all sorts of stuff on a west breeze.

  2. Cape Florida was pretty quiet at sunrise, with only a few small flocks arriving in the morning. The first real wave of migrants landing and making their way to our banding area was around 1030 AM. There was another surge of activity around noon and by 2 PM the entire Cape was pretty birdy. It was interesting to see the new species arrive throughout the day. Around 16 species of warblers were seen and 12 banded, plus quite a few indigo and painted buntings, yellow-billed cuckoos and a few vireos. Black & white warblers were everywhere. There were some blackpolls landing right after sunrise but a whole mess of them landed sometime between 230 and 330 PM, along with more redstarts and the first real push of black-throated blues we’ve seen. Treats included Tennessee, black-throated green, hooded (banded), veery and scarlet tanager.

    110 birds banded today; probably over half captured after 2PM. An even mix of typical Caribbean migrants plus some that probably left South America, like the blackpolls and red-eyed vireos. Birds were in a wide range of body conditions, from emaciated (hey I flew 3,000 miles last night) to very fat (hey I took the bus here last night from the Keys, where I was drinking at The Wreck all the day before). The surface winds were due west 10-15 mph at sunrise and continued around 15 all day long, which is pretty strong for that direction. Usually our westerly is pretty wimpy unless it’s from a hurricane or something. I guess these guys were displaced way to the east out over the Atlantic and it took most of the day for them to get back in to the coast.
