Audubon’s Radar Birdday

This is the radar from 5:00pm last night to 8:00am this morning.

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

It was on last night! Heavy migration was visible on radar in the northern portions of the country. Florida had its fair share of birdage overhead with most returns visible along the eastern side of the state. St. Pete radar shows some particularly heavy migration into the area. Birds were flying over Sarasota and just to the east of the area. West of Jacksonville also had some heavy migration overhead. This has been the main corridor for weeks now with the majority of migrants moving through this area while heading to points north.
Key West radar showed some precipitation over the northern shore of Cuba. This seems to have halted birds’ progress until later in the evening. Birds must have been flying low as they just appeared on KW radar out of nowhere. Miami radar had some action throughout the night and into the morning. Birds could be seen moving west from the Bahamas and Abaco Islands. Birds that were travelling north from Cuba also entered the Miami radar and seem to have dropped down over the Greater Everglades. Gumbo Limbo trail may be a hotspot today as well as the Big Cypress. In Miami we should expect a new crop of birds from the Caribbean with some goodies thrown in for good measure. Winds at 3k looked good for a flyover but the timing of the flight may leave us in on the action down here in Miami. With surface winds coming from the SSE would put more birds north of Miami but some east component may push birds inland to spots like AD Barnes and Kendall Indian Hammock. Along the coast we expect some new arrivals of Caribbean species at migrant traps such as Cape FL, Anne Kolb, John U. Lloyd, Spanish River and other migrant traps along the coast.
So get out there and bird; pass through and let us know what you saw today. With reports from you, we can further improve the interpretations that are posted on our site. Take a minute to think about John James Audubon today and the work he did back in his day. Can you imagine birding in those days with the optics that were available? His artwork lives on and gives us all a sneak peek into the world of birds back in the day continuing to inspire young and older alike today.

  1. All,

    Cockroach Bay has been pretty dull for migrants so far this year but we got a modest taste this morning. Saw 11 species of warblers highlighted by 12-15 Blackpolls, a Black-throated Green, a Cape May, a Tennessee, and a Yellow. An impressive sight was a flock of well over 100 Bobolinks flying overhead, many of which were giving full songs as they flew. 3 Solitary Sandpipers, a Semipalmated Sandpiper, 4 Gull-billed Terns were also present. The 4 Gull-billeds have been present for a while now and appear to be thinking hard about nesting on a small island in the mitigation pond. I’ve observed courtship feeding several times. While GBTE regularly breed at several locations in Hillsborough County I believe this is the first time at this location.

  2. Birded Sadowski this morning and it would have been a bad morning birding during a good spring migration, but instead it was a good morning during the worst spring I’ve experience in south Florida.

    Blackpoll -2
    Redstart -1
    Black and White -2
    Parula – 1
    Palm -1
    Common Yellow-throat – 1
    Black-throated Blue – 1
    Scarlet Tanager – 1
    Chimney Swift – 4or5

    Wooo Hoooo!

    At least it wasn’t another big fat ZERO!

    • Thanks for the report Dude!
