Laysan duck  (Anas laysanensis)

Range

The Laysan duck, also known as the Laysan teal, is endemic to the Hawaiian Islands, USA. It was once widespread in the Hawaiian Islands, but for the last 150 years, has been restricted to just Laysan Island (7) (8). In 2004 and 2005, a number of Laysan ducks were translocated to two islands of the Midway Atoll National Wildlife Refuge (9).

Habitat

The Laysan duck selects different habitats during different times of the day. Most adult birds use dense cover and hide in the terrestrial vegetation during the day, while during the evening and at night, it can be found in the central hypersaline lake on Laysan. It favours areas in the lake near freshwater seeps around the shore, especially when raising young ducklings, which are less tolerant of hypersaline conditions. It nests and rests in dense stands of shrubs and grasses (10).
