Birds on the Move

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 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!

    This shows, again, that flights of birds on radar are in no way an indication of great birding on the ground. In fact, in 5 years of tracking bird movements on radar I’m almost at the point of saying that a big flight of birds the night before = very slow birding the following day. This is an indication that radar is great at showing us the birds that will fly over us, but will not stop at our local spots. I have been out dozens of times after there have been big bird movements on radar and had VERY slow birding, but I have yet to have a single day of great birding predicted by bird radar. I’ve done much better by watchign weather patterns, especially large rain systems, but winds can also be a factor. At the present time, we have neither affecting south Florida, which explains why there are very few migrants around at the local hot spots despite big movements showing up on radar. Consider this groundtruthing, no pun intended.
