Birds on the move


Last night a low situated just offshore of the southeast coast set the stage for some southbound migration out of Florida, but little in the way of influx from the north. That said, the northwest wind flow that kicked in after midnight may have pushed some birds to the east coast early this morning.

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.

While north Florida remained relatively quiet, there was some migration evident over central and southern Florida. Birds can be seen leaving the mainland and heading to the Keys and both the Caribbean (from the southeast) and Cuba (from the south and southwest). With the mix of unstable weather and westerly winds, east coast locations could be good today (or at least the birds moving last night might be more evident there…how’s that for “sufficiently vague”?)

Good Birding! 🙂
