Migration Ahead of the Front

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.

Nocturnal migration behind the latest and greatest cold front was intense. On the heels of this front, come the waves of warblers, tanagers, orioles and grosbeaks to name a few. Ahead of the front however may be a bit slower.

The Sunshine State is living up to its name this weekend. Good weather isn’t necessarily the best conditions for a migrant fallout. Ahead of the front migration was turned down about 50 notches compared to the action behind the front. This is to be expected as the incoming frontal boundary brings on harsh winds and pelting rain. Birds are wise and chose to fly another night. The panhandle was cut dry from the supply line, Jacksonville radar still showed some coastal migration while Miami and Key West radar recorded an exodus of migrants that had been fueling up in the lower third of the peninsula. Both Miami and Key West radars shows birds taking flight over the FL Straits and the western Atlantic. Even though birds were leaving the state some birds will stay behind. Get out and see what’s moved south, some new goodies could be out there.

As this front continues to march southeastward, expect the best migration just on the heels of the front. If the frontal boundary has made it south of you this morning, get after it! As for us in FL, we wait for another big day!

Our computer is still down and we were unable to download and post the radar as usual so we are doing the second best thing. Below is a list of links to radar loops from 2am-6am.
The regional radar is in reflectivity mode which is best used to quantify birds and to get a picture of where they are moving from. The rest of the radar links are velocity radars, these are best used to determine speed and direction of travel. With these images you are looking at light blue-dark blue returns (incoming birds) and yellow-orange (outgoing birds). The grayish line between the two colors is the line of axis, this line will give you an idea of which direction birds are entering the radar from and which direction they are flying as they exit radar range.

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!
