  1. Although light, the westerly component in yesterday and today’s winds were enough to guide birds to Cape Florida. So far this week, ~430 birds have been banded, including good data for Evan and Kate. Blackpolls were in good numbers today but as usual, they skillfully avoid the nets. There was a large movement of Northern Waterthrushes that must have all come from the same staging area. Almost to a bird, they had no fat reserves and breast muscle was on the downside. It would be very interesting to know where they came from, in order to judge how the winds affected their flight. Other large movements were Worm-eating and Ovenbird — also not in best condition. Beautiful male Kentucky and Magnolia Warblers and Black-whiskered Vireos were nice to see. We expect to see many recaps in the next few days, as the birds feed and regain muscle mass and fat.

    I took a look at the radar to see if we can figure out where the birds were coming from. If you look at the wave of birds that headed north from Cuba you can see that they reach the lower Keys early into the evening. Flight speeds decreased over the Keys, we think this happened as birds met a shift in wind direction. At this point birds had almost dropped out of radar range but were picked back up near Biscayne NP on their way up to the Cape. Birds seem to have been blown out over the Atlantic near the Cape, we picked up returns making their way back east on radar indicating that the birds were indeed blown out to sea.
    This would definitely have caused a decrease in fat reserves as well as accelerating the rate at which the birds were metabolizing their muscles.

    Sounds like an awesome weekend to bird the Cape as new migrants will be coming in as well as the birds that will stay to fatten up for the next leg of the migration.

    Great week so far, we really miss being at the station 😦 Thanks for the great reports!

  3. Finally got out to do some birding at work. Been pretty quiet the last couple days.

    Worm-eating – 3
    Magnolia – 1
    Hooded – 1
    Blackpoll – 6
    Resdstarters – 7
    Black-and-White – 12
    Parula – 15

    Also found a Great Horned Owl nest with 2 chicks about 2 weeks old and 2 Chuck-wills nests
