Wind shear blamed for turkey vulture downing, Fishermen rescue 20-plus birds in Florida Bay, The Keynoter, November 20, 2010:
According to Fish and Wildlife's Sue Schaf, a call came in from the Marathon Wild Bird Rescue that the Twin Tails commercial fishing boat out of Conch Key had spotted "40 to 50 buzzards" in the water roughly 10 miles north of Marathon in the Florida Bay. ...
At least half the birds died, likely on impact according to Marathon Wild Bird Rescue Director Kelly Grinter.
"More than likely what they experienced yesterday was a wind shear or a micro blast. Both of them are conditions favorable for warm thermals to meet cold air and it's a funnel of air when these temps come together and they get pushed down to the ground," she said. ...
Grinter said several of the birds were let go at the ramp, the rest were taken to the rescue. She said three died there, but the rest will be released shortly. The hawk [identified as a broad-winged hawk] is being kept for two weeks as a precautionary measure.
A count of 275+ turkey vultures found dead. Every black dot you see is a vulture.
