Nocturnal Migration was Shutdown

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 cold front was forecast to stall, but it didn’t listen to the weather man. Migrants await better conditions for takeoff.

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

Not much movement on radar other than passing storms last night. Looks like NE winds reached the southern take off points for migrants. The Yucatán Peninsula, Belize, Honduras and Cuba all experienced northerly winds and clouded skies, this effectively shut down nocturnal migration. So we wait for a better night and hope for the floodgates to open, commence the BIG FLIGHT! Birds that made it to FL yesterday and Friday should still be around as we noted above, not much took flight. St. George Island experienced fallout yesterday and birds seen there will likely still be at the migrant trap.

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!

Nature is Awesome,
Angel and Mariel
