The Residual Effect

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.

Lots of birds dropped out over the state throughout the day yesterday. Tried and true migrant traps were the places to be. Today these places are going to be even more amazing as birds have had a chance to settle in and rest up from the long, hard flight. Widespread thunderstorms throughout the state caused birds to suspend migration and land, overcast conditions allowed birds to continue flight during the daylight hours as well. Miami birders were reporting hundreds of warblers flying overhead at 2 PM yesterday, this phenomenon continued on until nightfall. One could hear flight calls all afternoon, we received a phone call around 6 PM from a friend that was out grilling some burgers to report that many warbler flight calls continued to zip by overhead! Northeast winds set in behind the cold front that cleared the peninsula late yesterday. Birds were reluctant to fly last night and northeast winds had a lot to do with this. The second piece to the puzzle is that birds had a hard flight through the stormy weather which means that they may stick around for a few days as they fuel up for the next leg of their journey. Get out to your local migrant traps today and have a blast. Great diversity is being reported from Key West as we anticipated in yesterday’s post but also along the west coast, especially at Fort DeSoto where birders will have their hands or lets say bins full. Get your spring migration fix friends and share your stories with us, send us your reports and be our “boots on the ground” per say. Hope to hear from many of you today 🙂

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!
