Deep Tropical Moisture Continues; Migration Slows

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.

East winds dominated the night and continue today. Migration has slowed down a bunch ahead of the stalled front over North FL. High Pressure is building along the east coast and should change up things a bit in the following week. For now we expect migrants to be moving locally in search of better feeding habitat.

Skies over South FL have been cloudy with thunderstorms looming just offshore. It’s been this way for a few days now. It would be interesting if the block to the north clears and the stale weather reverts back to favorable migration conditions. We saw condition as such in the fall of 2010 here in South FL, migrants stacked up by the hundreds at local parks and migrant traps. We keep our eyes to sky and weather models with hopes that something will give.

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 badbirdz-reloaded@hotmail.com, 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!
