A Disturbance in the Force

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. The stalled front will begin to move back north as a warm front today. A disturbance over the Gulf has begun to move into the Panhandle ans will cause widespread showers and thunderstorms across the region.

Migration was slow last night, most of the apparent movement was moving S->N beyond the stalled front, north over Central FL. A low level disturbance will affect the panhandle and will bring in lots of rain. Look out for any migrants that made it up into the region, these birds will likely drop out and wait out the rain. Small movement of birds were recorded over the Straits heading SE->NW. Miami radar picked up birds coming from the east, most of the activity seems to have moved NW once it entered the area. Some of these birds may have settled in at inland migrant traps such as AD Barnes, Kendall Indian Hammock or farther west into Everglades National Park. Tampa radar did not see much action last night. Birds were once again moving S->N along the east coast making their way into NE Florida and GA.

The stalled front has really put a damper on nocturnal migration the last two nights. As the front begins its northward march as a warm front, we expect a change in conditions that should prove favorable for nocturnal migration to kick start back up. Keep an eye out for diurnal migration today; lots of birds were moving over South Florida during the day yesterday. We saw some good movement down in Key Biscayne yesterday afternoon. Falcons were coming in off the Atlantic as well as some swallows and passerines. If you have some rain during the day, look for an increase in activity after the rain has stopped. Have a wonderful Sunday everyone.

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!
