Stalled front stalls migration


Well, the cold front that was moving south over Florida has now migrated north to the FL/GA border and will likely remain there for the next few nights. Here’s the radar from sunset last night through 6:00am 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.

Small pushes of birds were evident on the central and south Florida radars last night; with a few clusters of birds seen migrating from the southeast coast into the Atlantic, the Everglades into the Keys, and the Keys into the Straits of Florida. Less migration was evident in north Florida, where the frontal boundary was situated. Easterly and southeasterly flow will continue over Florida for the next few nights keeping migration to a minimum. We’ll have to watch the weather and see if anything arrives by the end of the week to stir things up.

Good Birding! 🙂

  1. A few birds slipped through to Cape Florida. There seemed to be a lot of turnover between yesterday and today, and 24 birds were banded, all new. Highlights were Maggie and Wood thrush. Black-throated blues were prevalent, as were a gang of punk Cape Mays that threw everybody else out of the favorite ficus tree. Other nice birds seen ony were black-throated green and first of season Myrtle warbler.

  2. I had a nice group of 13 warbler species in my yard (Seminole County) first thing Monday morning, including Bay-breasted, Tennessee, Black-throated Green, Yellow-rumped and Orange-crowned. There were also 2 Rose-breasted Grosbeaks and a Ruby-throated Hummingbird. I figured the birding would be good elsewhere, so I headed over to Maitland Community Park where I had a lot of trees, weeds and blue sky. And a couple of catbirds and Palm Warblers. Migration is funny that way.
