Last night birds were on the move within the state. Birds that hit the SE coast of Miami yesterday can be seen flying NW towards the Sarasota/St. Pete/ New Port Richey area. Birds had to fly through rain to make it to the coast, hopefully these birds made it ok as they could have been low on fat reserves due to last two hard days of migration. Migrants were picked up moving into the area for most of the night and late morning, some birds were pushed out over the Gulf and made their return in the area of Green Key.
Down here in Miami we did note many the returns were headed out but some birds were just moving locally, probably looking for better foraging habitat. A small wave of migrants was picked up coming in from the east despite the north winds, these birds came in very early (11:45pm or so) which makes us believe that they continued their journey north once they reached the mainland. These returns came in around Ft. Lauderdale, if the birds grounded we would expect the best locations to be Evergreen Cemetery, John U. Lloyd, Anne Kolb etc.
Well lets see what happens this evening. Please post your sightings below, just click on the comments just below and to the right of this intrep. Good birding to all.

  1. The little push into SE Florida yesterday brought a decent group of warblers to Sadowski. I got 11 species in a short stop in the afternoon, with best being 2 Blackpoll, 2 Cape May, and a Magnolia. Lots of Worm-eating and Redstarts. Trey came over right away, and Rock showed up as I was leaving. This morning Trey said many of the birds had left, but some were still around.

    The push must have missed Matheson altogether, since this morning I only got 4 species and 5 individuals between both sides of the road. Winds are forecast to come out of the SW Wednesday and NW Thursday. Maybe thursday will be better. There may be another wind shift early next week.


  2. Banded migrants this morning in southern Hillsborough County. There was an obvious increase in palm warblers and catbirds, but also observed redstart, hooded, prairie, more black-and white warblers than usual, indigo buntings etc. One of my better days of banding in s. Hillsborough.

  3. Yesterday’s SFBO total was 166 with large numbers of Cape May, Prairie, Worm-eating, Black-and-white, Black-throated Blue and Indigo Bunting. Though no real hard-luck cases, most of the birds had little fat reserves and pec conditions were only OK — all pointing to yesterday’s phenomenon of being blown SE and having to fly NW to find land (Cape FL) — as shown by radar ~8:30 AM.

    Today’s total was 50, probably residual birds that decided not to migrate last night. Their condition was so-so. As Michelle would say, the cake was a Hooded Warbler but the frosting was an adult male Kentucky Warbler. Few Bobolinks flying around today.

  4. Awesome, thanks for the sightings! We really appreciate it.

    Birds definitely took off last night, on the SE mosaic radar you can see the birds leaving Miami. As the birds flew NW they encountered some storms which made the returns drop out of radar range, the returns were picked up once again just north of the weather making their way into the Sarasota/Tampa/New Port Richey area.

  5. Fairly poor afternoon in Kissimmee with only 6 species of warbler seen. The best birds were my FOY American Redstart, and my first confirmed Louisiana Waterthrush.

  7. April 20 (delayed comment)
    At Goulds (South Dade East of Redland/North of Homestead) – Cauley Square had more bird activity than noted in some time.
    Good numbers of Cape May Warblers, several Blackpolls, many Black-and-whites, Parulas, and a few scattered individuals of Worm-eating and Black-throated Blue. A single Prairie Warbler was also around.
    Gray Catbirds are truly – all over the place!

    I seem to be orbiting around the same group of species this week.
