Federal scientists are on the lookout for the Eskimo curlew, as they work to determine if the elusive shorebird last seen two decades ago still exists.
The U.S. Fish and Wildlife Service said it is seeking any information about the Eskimo curlew, a tundra-nesting bird once abundant over the skies of North and South America, which was nearly hunted into oblivion by the mid-20th century. The agency, which made its announcement in the Federal Register on Wednesday, will review whether the bird should continue to be classified as endangered or formally designated as extinct.
The last sighting confirmed by the Fish and Wildlife Service was in Nebraska in 1987, said Bruce Woods, a spokesman for the agency. An unconfirmed sighting -- of an adult and a chick -- was recorded in 1983 in Alaska's Arctic National Wildlife Refuge, Woods said.
The Eskimo curlew population once numbered hundreds of thousands, according to the Fish and Wildlife Service. It is the smallest of four species of Western Hemisphere curlews, and is known for its long migration route from Arctic tundra breeding grounds to wintering lands in South America.
