Wildlife Service Baffled by Exodus of Birds From Florida Isle

Tens of thousands of nesting birds vanished this spring from a Florida island refuge where they have come to breed for decades, leaving behind their unhatched eggs and mystifying wildlife officers trying to figure out why they disappeared. Vic Doig, biologist for the U.S. Seahorse Key, said the birds have been coming to Seahorse Key on Florida’s Gulf Coast for more than a century, and in recent times averaging 10,000 to 20,000 breeding pairs a year.
