Migration over Florida


Here’s the radar from sunset last night through sunrise this morning.

Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.

Migration was definitely happening over the Sunshine State last night; the heaviest of which occurred over the northern third of the state, with lighter movements over the lower two-thirds. Winds weren’t exactly optimal for migration over central and southern Florida, with northeasterly winds up north changing to easterly and southeasterly winds down south. Migration was extremely dense over the entire eastern flyway north of Florida, which would also explain the large influx of birds into the northern part of the state. Since easterly winds did dominate last night, I’d expect inland and west coast sites to have the best birding conditions this morning, with the highest probabilities of migrant concentrations in the northern third of the state.
Please stop back by and let me know how it went!

Good Birding! 🙂


  1. Hi David,
    Yesterday we went out birding with the TAS group. The walk was at Matheson Hammock Park, we birded the service road and the east trail as you enter the park. The morning was not very birdy but we still found some migrants. The most notable being the Blue-winged Warbler, we also heard two Eastern Screech Owls calling. A beautiful Short-tailed Hawk in a light morph soared above the whole group and checked us out. We did see 10 other warblers and some RT Hummers as well. This morning Roberto was able to find a male Rufous Hummingbird chasing a Ruby-throated around no Blue wing but another migrant! Don’t have a list for the morning walk but after the walk Dan my wife and my self went out to Bill Sodowaski to bird a little more. At the park we found the following.

    1 Chuck-will’s-widow
    1 Acadian Flycatcher
    2 Red-bellied Woodpecker
    13 N. Mockingbird
    5 Red-eyed Vireo
    1 Northern Parula
    11 Blue-gray Gnatcatcher
    1 Red-Shouldered Hawk (heard)
    2 Ruby-throated Hummingbird (fighting chasing after each other)
    3 N. Cardinal
    1 Mourning Dove
    3 Northern Waterthrush
    3 Ovenbird
    1 Common Grackle
    7 Blue Jay
    1 Black-and-White Warbler
    2 Double-crested Comorant

    Last night and this morning we were treated to lots of rain and thunder, hopefully it will clear and leave some migrants behind.
    Thanks for posting the radar everyday we think it is a wonderful birding tool. We can’t thank you enough.

  2. We had a small influx at Cape Florida this morning and banded 40 new birds; up from 17-20 a day over the weekend. They were the standard Caribbean migrants like ovenbird, worm-eating and American redstart, with a Traill’s flycatcher thrown in for interest. We did hear the first yellow-bellied sapsucker of the season.

  3. Wow! A&M – thanks so much for posting numbers- it’s a real help when making the connection between the radar and relative density. You two have so much excitement in your posts- I love it.
    Michelle, thanks as always for your posts from the Cape. For anyone who’s unclear, Michelle gets up in the wee hours, drives all the way from Homestead to Cape Florida to band birds all day, and still makes time to post her sightings before passing out…what a trooper!
    Hey Mad Dog- Watch out of Flickers- 600 came through Cape May on the morning flight today!

    Good Birding!


  4. Hi David,
    This morning after taking Mariel to work I was driving on the 826 South on the way home when the sky started to clear up a bit so I decided to make a stop at the lake and the cow pastures in the Miami Lakes area. Melato had reported a Bald Eagle about a month ago at a dead tree in the middle of one of the fields near the lake. So I have been checking the area periodically to look for raptors. This morning I passed by the tree on Commerce Way and was surprised to see a raptor on the tree. I parked and walked across the street to get a closer look. To my surprise the raptor was a adult female Northern Harrier, this is my first Harrier of the season last year we observed two adult males soaring over our home on two separate occasions. The bird was perched low about ten feet off the ground on a dead tree in the middle of the field. I stood at the edge of the fence and observed the bird for about fifteen minutes. I was able to see the facial disc it reminded me of an owl. When it decided to take off toward the lake and that is when I was able to further confirm the Harrier by the white uppertail coverts. It was nice to enjoy a gloomy morning with such a majestic raptor.
    After the Harrier left I checked out other areas and found the following:

    1 Northern Harrier (female) FOS
    1 Osprey
    1 Loggerhead Shrike
    1 Great Egret
    25-30 Cattle Egret
    35 Swallows (too far to ID)
    22 European Starling
    10 Boat-tailed Grackle (male & female)
    10 Mourning Dove
    2 Double-crested Comorant
    1 Anhinga (female)
    2 Common Moorhen

    Well we are heading out to bird soon.
    We will report our findings later tonight.
