Small movements down the Sunshine State


Weather and southeasterly flow kept most migrants stationary last night, although small movements were evident on both the Miami and Key West radars.
Here’s the radar from sunset last night through sunrise this morning.

Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.

Even though some heavy storms made their way across Florida last night, the lack of influx of birds means little change on the ground will be evident this morning. Two small movements were evident last night; the first from the Miami area down to the upper Keys, and the second from the Cape Sable / southern Everglades down to the Lower Keys. Given the wind direction and speed, it’s likely that these are shorebirds (strong fliers) rather than passerines, but that’s pure speculation based on the weather conditions.

Good Birding! 🙂
