Nocturnal Migration Continues Over FL

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. Easterly winds persist over the forecast area due to high pressure sitting north of FL. We can expect many of last night’s migrants to head NW in a rush. With little precipitation to ground these migrants, most will likely fly into states north of us. As the next frontal system slides east, high pressure will mosey on over to the western Atlantic allowing for a wind shift and better birding conditions.

Last night birds were quickly moving over the forecast area, most of this migration was headed SE->NW. High pressure systems can put a real damper on east coast locations as birds get pushed west into interior and coastal locations along the Gulf Coast. Many birds were recorded migrating over the FL Straits overnight, the first batch were headed NW but a late morning movement of migrants look to be heading S->N. As of sunrise these birds were still making their way in the FL Keys region. This movement could represent birds coming from farther south of Cuba or the Bahamas; Jamaica and other islands of the West Indies could be the source of this late incoming flight. With daylight eminent and scattered showers moving through the area, we would expect some birds to land along the chain of Keys. Radar images favor the middle Keys; state parks such as Bahia Honda, Curry Hammock, Windley Key and other city and county parks could see a lot of this action. If birds decided to continue over the Keys their first destination would likely be the Cape Sable/Western Everglades area and into the Ten Thousands Islands and Sanibel. Lookout out for late morning arrivals along these areas; chances are that diurnal heating coupled with a sea breeze, could develop showers and maybe even thunderstorms that would bring down birds in a rush. Most of the nocturnal flight should have been able to make it past many of the states migrant traps. There are always those migrants that trickle out so a check of your local birding spots and traps would be a good idea to see if any new arrivals are at hand. We are halfway through the week; hump day as some call it, a front is making its way east and birding conditions will improve over the weekend. Have a safe and fun day 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!
