The Well is Not Dry; Yet!

This is the radar from 5:00pm last night to 11:00am this morning.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

As the title reads, migrants continue to make the flight across the FL Straits as it gets later in the season. Steady SSE winds at lower levels are in part due to high pressure that is lingering over northern parts of the state. A weak frontal boundary is sliding in from the NW and can drop some considerable amount of rain over NE FL. How this will affect migration in these parts? We will have to wait and see what occurs over the weekend.

Migrants were taking the westerly route once again and mostly stuck to coastal areas. To the east Jacksonville radar was very active with pulses of migrants flying overhead. As morning came you can see how signals on the radar appear in a “donut” shape indicating that migrants were flying HIGH overhead. This gives us an indication that the southerly component in the winds have given the birds a tailwind into GA and the Carolina’s.

As migrants flew over the Keys they were flying in a SE->NW direction and flew out over the Gulf. With mostly clear skies over the Gulf these birds may be attempting a Gulf-crossing. As in the case of yesterday the NW trajectory carries these birds away from Florida’s migrant traps. Farther down to Central FL, small to moderate migration was overhead. In these areas we would expect the best birding to be found at tried-and-true migrant traps.

Working our way down to South FL we look at this area for new arrivals from the eastern Caribbean. Be on the lookout for vagrants or sneaky buggers such as Bicknell’s Thrush and Connecticut Warblers, this is their window and the winds are right on!

If we go down to Miami and the Keys chain we can look but we may not see too much evidence of migration today. Winds continue to carry birds north of us down here. There was some activity entering the radar that may have put down but smaller numbers of birds are harder to detect on the ground and radar alike. Again as we mentioned for Central FL hit your local migrant traps and hope you get lucky. A TAS Bird Walk is taking place down in Key Largo today, lets hope that some of the birds seen early morning on the Key West radar dropped down for our fellow birders to enjoy. We hope to hear from one or more of you on the walk today 🙂

As always, Badbirdz depends on YOU to report your sightings and be our ‘eyes on the ground’, so please come back and give us an idea of what you are seeing in your neck of the woods. This will help us better understand the radar images and in return we can pass this knowledge onto you.

  1. Eight warbler sp. (Cuban Yellow, Prairie, Blackpoll, Cape May, Redstart, Palm, Parula and C Yellowthroat) in Key Largo this morning, but low numbers. A few Indigo Buntings on Carysfort Circle. Most unusual was a single male Bobolink deep in coastal hammock along Dynamite Trail in Dagny Johnson SP.
