The Blockade

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.

Our biggest ally has become our demise. That big cold front that rushed down, chuck full of migrants, stalled out and is now acting as a blockade. As this front sits, almost horizontally from the northern Gulf to NE FL it acts as a block for migration ready birds. Optimal winds behind the front encouraged many migrants to head south, but now they are stuck, waiting on this block to clear. We are waiting for the second half of the week in anticipation that this front will fire back up and head south with birds on its heels. For now we can look out for local movements by birds looking for better foraging habitat. Tried and true migrant traps will your best bet today as birds are dispersed throughout the landscape making them harder to detect. Enjoy your 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!
