Big migration over Florida and entire eastern flyway!


Now this is what we like to see- a nice flight for Michelle Davis’s (AKA MadDog) birthday! So what will be her birthday bird this morning? Anyone care to guess?
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.

Birds were moving all up and down the east coast last night, as the cold front cleared most of the country by early yesterday. High pressure over Lake Okeechobee kept the front from clearing Florida, where it is forecast to dissipate later today. This lead to easterly flow over most of the the Sunshine State, while everyone to the north experienced NNW windflow. As I mentioned last night, the result was very heavy migration from north Florida northward, and moderate to heavy migration down the peninsula. Either way, there was a good push of birds both into and through the state. Since easterlies did persist, we would expect the best birding along the west coast and at inland sites, with the east coast experiencing a lower, yet still noticeable influx.

Okay- gotta go groundtruth! HAPPY BIRTHDAY MADDOG!

Good Birding! 🙂


  1. Thanks for keeping us up to date!

    Happy Birthday Michelle, hope you find some great birds today.

    I was out birding Royal Palm yesterday late evening and saw warblers, but most all of them were flying south. It was overcast and I guess the birds took the opportunity to get an early start. Over all I saw some good birds yesterday and can’t wait to see what today brings.

  2. Birded a local park in the Orlando area on Sunday. Six common warbler species in very small numbers. Also had a male Scarlet Tanager, Yellow-billed Cuckoo, Eastern Wood-Pewee and 3 Eastern Kingbirds flying over.
