Friday Migration

This is the radar from 7:00pm last night to 7:30am this morning.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

Last night winds were working in favor of migration, due to the storms birds may have chosen to stay down though. With an N to NNW wind in the panhandle, a swift NNW wind down the west coast and finally south winds over the keys. Migrants that were on the move followed a SSE direction for most of the night; with birds finally taking off to Cuba last night despite a headwind. These birds may have been shorebirds as they had to fly into a swift south wind; we are not sure how many songbirds are in a hurry to make it to Cuba this early in the season.
Jacksonville radar had moderate activity through out the night; the panhandle experienced the best migration along the western most edge of the panhandle. The central flyway was amazing last night, all radar were lit up! Birds moved late in the night off the panhandle and may have been concentrated around the St. Pete area. Storms were moving inland as birds were entering the radar; new faces should around your local hotspots today.
Melbourne radar showed migrants moving through on their way south, with a WNW wind helping birds make it down to the Miami radar. Miami radar had activity for most of the night a check of the velocity image shows birds entering and leaving the radar; Miami may have been sucked dry by the migration vacum =-(.
Birds that made it past Miami seem to have made it into the Key Largo area, with lots of signatures we expect migrants to be around there today. Miami radar picked up birds late in the morning moving a SSE trajectory which may have made birds overshoot the coast. With a good SW wind birds will make a late arrival along the coast, Matheson, Cape FL, Sadowski may be holding these birds if they did not fly further south.
The Keys radar showed some of the best movement thus far, migrants took to the wing and headed towards Cuba in good densities. Birds could be seen making their way out of the KW radar with a SE heading. Migrants should be noticeable on the ground as birds that flew past Miami were headed south, Key Largo to the Middle Keys seem best to bird today.
Coastal migrant traps should be checked for new arrivals, from Miami to the Keys it looks as if birds made it in last night. Good Birding to all and have a great weekend. To all TAS birders we will see you tomorrow at the Sod Farms; let’s hope we have a great day out there.

  1. Much slower at Matheson this morning. No sign of the Kentucky. Only other birds seen were a LA Waterthrush, 2 Ovenbirds, and 1 Redstart. A few Gnatcatchers rounded things out. Seems many of the birds from earlier in the week have moved on.

  2. Hey everyone,
