Anas laysanensis

The critically endangered Laysan Duck, Anas laysanensis, has had a very successful 2007 breeding season, say US Wildlife Biologists. Population numbers have quadrupled since 42 individuals were moved across the Pacific and released at the Midway Atoll National Wildlife Refuge in the US in 2004.
