Translocation and disease monitoring of wild laysan ducks
The Laysan duck (Anas laysanensis), also known as the Laysan teal because of its small size, is a critically endangered waterfowl species that once occurred widely across the Hawaiian Archipelago. For the past 150 years, however, it was restricted to a single population on Laysan, a 4-square-kilometer (1.5-square-mile) island with a hypersaline shallow lake. Laysan is part of the Hawaiian Islands National Wildlife Refuge in Papahanaumokuakea Marine National Monument.
