Oh the east wind doth bloweth


Can you tell that I have an east coast bias?? I’m constantly rooting for west winds to blow migrants eastwards… I realize this, and I wonder if the west-coast birders take note when I post.. if so, I apologize, but it’s hard-coded in my genes.
Anyway, here’s the radar from last night through 5:30am.

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.

The Key West radar showed a moderate pulse of birds entering the radar early this morning. We can surmise that birds were flying low based on the point at which they enter the radar’s view, which was over halfway across the Straits of Florida (remember that the radar view is like an ice-cream cone, lower to the ground at the source, and higher as you move out from it). It appeared, based on the velocity image, that some of these birds continued on into the Gulf after crossing the Keys, although it’s likely that some put down during the early morning hours.

As for the Miami radar, a moderate density of birds could be seen taking off after sunset and heading in a NW direction, while only a small pulse from the Caribbean made it to the southeast coast early this morning.

Looking at the regional radar, it appears that most migration was limited to the mainland and panhandle area of the state, with strong signals extending into the Gulf Coast states.

The next few nights look like similar conditions, with a chance for a more southeasterly flow bringing more birds into the state, but (sigh) favoring the west coast. Time for a trip to Fort D, eh?

Good Birding 🙂
