Westerlies trigger some migration over SOFLA

Only 4 more days to take the woodcreeper/badbirdz-reloaded, online survey! To the 30 of you who took the survey so far, thanks! To those of you considering taking it, let me assure you that It’s quick, painless, and will really help me improve the site, so please take a few seconds to click a couple of buttons. 🙂
Thanks in advance -David

As the remnants of TS Fay make their way north across the state, the southwest part of the storm continues to bring west/northwest winds across the southern half of the state. This appears to have triggered some migration from St. Petersburg to Miami, and down into the Keys. Here’s the radar from 7:00pm last night through 5:00am this morning.

While migration was not heavy by any measure, there were moderate levels of movement visible on the St. Pete radar just after sunset. The Miami radar indicated moderate levels just after sunset, but these did taper off in the late evening. It does not appear as if the bulk of the birds moving from the west coast actually made it all the way east, but given the wind speeds last night, we should see a pulse of new birds along the southeast Florida coast this morning. As for the Key West radar, the images only showed a small pulse of birds leaving the Keys and heading southeast. Any reports from the field would be great, so stop by when you get a chance!

Good Birding,

  1. Not much going on today at Cape Florida, either. I thought today would be busy because I saw that departure out of Tampa, heading our way…this morning birds were moving on MIA radar exactly over land; no drift at all out over the bay or ocean that I could see. 12 birds banded; appeared to be what was around yesterday. Winds going more S; they never got more than WSW at Fowey Rock yesterday, and very briefly. We did catch FOS BTBW & REVI, and another LOWA.

  2. PS hey how do I put a picture in my box?
