Migrants Are on the Move

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. It was a wet day for South Florida yesterday. Strong thunderstorms swept the region, dropping between 2.5–5 inches of rain, hail and delivering damaging winds. With the loss of diurnal heating we expect a much more stable atmosphere overnight. A general E—ENE switching to ESE wind triggers some heavy migration of the state. Look out for new arrivals in the northern portion of the state in the morning.

Radars lit up overnight; migration was triggered with the help of favorable winds over the state. With a general SE–>NW movement, most migrants should be seen at migrant traps north of Central FL in the morning. Check out your favorite migrant trap in your area to see if new arrivals dropped down. Little to no precipitation over the state means that migrants had a clear and safe passage. Birds would make it farther but not faster due to leisurely prevailing winds. Tampa radar was very active throughout the night; winds will carry birds over the interior portion of this region. Many birds were flying up the east coast from Miami to Jacksonville; expect new faces at migrant traps along the coast and near coastal areas. The FL Keys was the exception, scattered showers were moving over the area, but birds were not flying over as they were the night before; little is expected in the way of new arrivals in that area. States north of FL will see an influx of FOY birds tomorrow, be on the lookout for Cape May Warblers as they have been moving over FL in good numbers. Have a wonderful day!

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!

Nature is Awesome,
