Light flight on strong east winds

Actually, the radar last night looked extremely similar to the night before… so much so that I had to do a double-take in my early morning haze before confirming that they were indeed different. Here’s the radar from 7:00pm last night through 5:00am this morning.

You’ll notice that the “big” difference between yesterday and today was simply fewer birds migrating last night. East winds were blowing strong across the entire state (with some northeasterly winds over south Florida, and even some south-easterlies over north Florida) and only small pulses of birds could be seen taking to the sky after sunset. The most substantial movements were two small pulses out of Florida; the first from Tampa/St Pete into the Gulf, and the second from the southern Everglades and the Florida Keys into the Florida Straits. Otherwise only a very small number of birds could be seen heading WSW across the Miami and Melbourne radars. West coast sites will have the best chance for picking up some of these birds, but otherwise expect little to no change in bird density or composition.

Good Birding,

David
