Moderate Influx of Migrants into S. Florida

This is the radar from 5:00pm last night to 9:00am this morning.

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

With a weather system over us all night long it was interesting to see birds fly into the bad weather. A SW wind was prevailing from the surface to the upper levels of the atmosphere which may have been a cue for the birds that did take off to the mainland. Returns were picked up on radar leaving the coasts of Cuba heading NE riding the coat-tails of a squall. These returns looked as if they reached the southeastern shores of Miami this morning. Check all coastal migrant traps for new incoming migrants that may be arriving at all times today off the water. Overcast conditions are great for birds as they can elect to fly further with lower air temps. Hope to hear from the Ladies at the Cape, no offense Evan with some information on whether we read this correctly or not. Let’s hope for a change in composition down here on the east coast as it has been slow all spring with the exception of the fall-out at the Cape earlier this spring.
As for the rest of the state, stormy conditions seem to have grounded birds and small to no movement was detected on radar other than that of birds flying into Georgia.
Hope to hear from you all with any sightings today, it may be rainy and cloudy but the birds should be around. These can be great conditions for migrant birding or can be a bust. Good birding to all.

  1. Some of the guys coming up from Cuba put down at Lucky Hammock Annex in south Dade this morning. We heard warblers and a few bobolinks in the air low overhead at sunrise, and ono ur way back from chasing sparrows we stopped at LH & LHA. The annex was best, with lots of activity as warblers & buntings were flying along the road or just overhead, all heading north. A few stopped to investigate the ficus trees & shrubs in the area. Not massive numbers but enough to feel like a fallout!
    Guestimates:
    indigo bunting- 15
    painted bunting-1
    blue grosbeak-1
    solitary-headed vireo-1
    gray catbird-dozens
    palm w-40
    yellow-throated w-3
    common yellowthroat-10
    northern waterthrush-2
    magnolia w-1
    american redstart-25
    black & white w-10
    worm-eating w-4
    black-throated blue-1
    prairie w-15
    80% of the sexable birds were males
    plus gray kingbird & great-crested flycatcher nestbuilding

  2. Cape FL reaped the benefits of the weather configurations this morning, as birds dropped into the park at mid-morning. There was a big movement of Cape Mays and Indigo Buntings, as well as Worm-eating, Northern Waterthrush, Black-and-white, Prairies and a few Blackpolls. I also had some larger passerines: 2 Rose-breasted Grosbeaks, Yellow-billed Cuckoo and male Baltimore Oriole. I had to leave early but banding continued into the afternoon. I’ll report back with condition of birds. Virginia Key saw influx of shorebirds: Black-necked Stilts, Least and Solitary Sandpipers. Had 20+ Barn Swallows late and Blue-winged Teal numbers are increasing. There were several flocks of Cattle Egrets coming off the ocean at mid-afternoon and Bobolinks are everywhere.

  3. A quick run by Kendall Indian Hammock around 11:30 AM – between drizzles – had me lingering there due to plenty birds despite having to run on a super busy schedule.

    Most numerous were Cape Mays, almost entirely males in bright plumage keeping high in the canopy – an estimate of a couple dozen in the vicinity of two oaks within the hammock might give sense of how many were present throughout.

    American Redstarts were also quite numerous, in all expected plumages.

    As I was ready to leave, the Blackpolls finally made their entrance, with a handful of males joining the large feeding flock. No females in sight.

    Associated with this sedentary feeding mass were also various Black-throated Blues, half a dozen Black-and-whites, at least a pair of Parulas (vocalizing), and single Worm-eating and Black-throated Green.

    A large and “noisy” flock of some 40+ Waxwings (possibly more) wheezed its way over and over above the canopy. My guess is that there were several broken flocks – I could hear them constantly.

    As the rain started to pick up, the birds appeared unaffected and lingering – I had to run – but very satisfied indeed!!

  4. Went to SADOWSKI after hearing about migrants in other locations. Several of us birded the park and we came up with modest numbers of migrants.

    BT Blues – 10-12
    Prairies 6-8
    Palms 2
    Black and White 15-20
    Cape May 5
    Wormeating 3-4
    Redstart 10-12
    Northern Parula 6
    Magnolia 1
    Blackpoll 3
    Common Yellow-throat 2
    Indigo Buntings 6

    Not bad for a little park…

  5. I forgot… a several Red-eyed Vireo were seen as well.

  6. Got out to Caloosahatchee Creeks Preserve East (North Fort Myers) for an hour and a half before sunset. Not many migrants but nice variety for a fairly so-so location.
    5 Gray Catbird
    1 Black-throated Blue Warbler
    1 Prairie Warbler
    8 Palm Warbler
    1 American Redstart
    1 Worm-eating Warbler

  7. Thanks everyone, migration is awesome!
