BAM! Migration!!

National Overview

Below is a snapshot of the national map with radar and weather fronts. Use this map to get an overall feel of migration and how weather affects nocturnal migration. The right conditions triggered a widespread migration over the night! With a tailwind, birds were flying high and far. Florida may see a flyover but we will wait and see.

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

We will post an in-depth analysis of the radar soon. Birds were moving N at a rapid rate and Southern Florida will likely be passed up, birders in Central and North Florida as well as the panhandle should be on the lookout for new arrivals. Heavy migration was evident over the FL Straits and over Miami. Be back soon.

We’re back! Migration was heavy over South FL last night, most of this movement likely flew over and did not land. As the sun broke through the clouded sky some later arriving birds could have dropped out over the Greater Everglades. We would hit areas from Mahogany Hammock to Flamingo if we were off today. As we look north both Melbourne and Tamps radar stations were busy. Tampa station shows a large exodus from south of the Bay Area last night. The source of the flight seems to be either Sarasota or Manatee County or both. A new group of birds were flying NNW as a band of storms slid in from the west. Birders in the following counties (Pasco, Hillsborough, Manatee, Sarasota, and maybe a bit inland in Desoto, Hardee and Polk counties) may want to go check and see if birds suspended migration due to the rain.

Melbourne radar recorded lots of showers overhead into the morning hours, birds that were moving up the coast may have also dropped out over coastal migrant traps. Looking at the velocity radar tells us that birds were moving NNW over Miami during the night. A few hours before daylight birds started to fly a more NNE direction and to the east of Lake O’, birders from Palm Beach to Merritt Island could see some new arrivals, especially where it rained between 3-6AM. Get out there and bird, let us know what you are seeing.

As always Badbirdz depends on its readers to help us understand the magic of bird migration. We ask our readers to take a minute to email us at, post a comment on the site or share what you are seeing on our Facebook page. As a whole the Florida birding community is large and enthusiastic about bird migration, lets join together this year to make Badbirdz an integral part of every birders toolbox. Together we can track and monitor birds and learn more about this phenomenon called MIGRATION!
