Heavy Flow Of Migrants Over Florida Tonight!

This is the radar from 5:00pm last night to 4:30am this morning.

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

Migration was definitely evident on radar last night, birds could be seen moving through out most of the state. From looking at the regional composite, you can see migrants taking off a little after sunset from the southern half of the state and moving in a general NW direction. Returns became concentrated in central Florida and looks as if birds were choosing their routes north at this point. From here returns could be seen flying both NE as well as NW, the heaviest flow north was over the Jacksonville radar though. Birds were headed out of Florida and making ground into Georgia, returns are scattered all over the state as Florida just dumped a bunch of new faces on Georgia.

Migrants were also moving over the FL straights, a large wave of migrants took off from Cuba and headed almost due north into the western portions of the Everglades and points north such as Sanibel/Ft. Myers. This area of the state looks particularly good for birding in the morning, hopefully we will hear from west coast birders today.

Miami radar showed movement on the way out in the early evening, but as the night went on the wave from Cuba made it into the area. Looks as if birds made it here early enough to overshoot us, but as birds reached the coast returns started to crowd the shores on the both side of the state. It looks as if birds may ground and given the density of the influx there will be new birds around in the morning. With ESE winds birds can easily overshoot us but if they don’t, inland locations look best for birding with the winds aloft. Migrant hot spots such as ENP, Flamingo, Lucky Hammock/Annex, C-111e canal, Castellow, KIH, Barnes etc. should offer the best birding. Coastal locations should also have some new birds around given the amount of birds that were moving last night. There were some returns visible on radar coming in from the western Caribbean as they made their way into southeastern Miami/Dade. It would be interesting to see reports from both coastal and inland locations to compare species composition and overall density given the ESE winds and migrants coming in from different geographical locations.

Let us know what you see out there birders, looks as if Florida will have new birds around in different locations today. Enjoy this spring migration! Have a good weekend everyone.

  1. The TAS walk in Cape Florida wasn’t as birdy as hoped for but we did pull out 13 warbler species. Kate brought in a Grasshopper Sparrow at 8 AM — always a treat for SFBO. Evan banded a Worm-eating Warbler just in time for me to show the group, and it may have been the hit of the day. Back to weather and birds: The ESE winds were brisk today, keeping our numbers down. We had the usual Caribbean migrants, along with a male Hooded Warbler and several Blackpolls. Looking forward to Tuesday, when the 5:30 AM radar may be green over Cape Florida.

  2. A fairly decent afternoon in Kissimmee at Shingle Creek. Not many warbler were present in terms of numbers, however the variety was good with 11 species seen. The best bird by far was a Swainsson’s Warbler that fed in the base of a fallen tree (life bird). Here is a list of all migrants seen.

    Ruby-throated Hummingbird-1 female
    White-eyed Vireo-1 (several heard)
    Gray Catbird- only 10-12
    Northern Parula- 2 males (many heard)
    Black-and-white Warbler- 1 male
    Black-throated Blue Warbler-3 males
    Yellow-throated Warbler-1
    Prairie Warbler-1 male
    Blackpoll Warbler- 2 male/female
    Swainson’s Warbler- 1
    Northern Waterthrush-1
    Waterthrush sp- Heard
    Common Yellowthroat- c.10
    American Redstart-8 (5m/3f)
    Indigo Bunting-1 male
    Painted Bunting-1 female
    Bobolink-7 (5m/2f)

    There was a flock of over 100 Bobolink in the overgrown, unfinished are of my subdivision yesterday.

  3. Birded Ft George Island in NE Florida this morning. Numerous Bobolink flocks flying over and 14 species of warblers seen. Small numbers of birds and no unusual species.
