Laysan duck  (Anas laysanensis)

Description

The Laysan duck, so-called as it occurs on the Hawaiian island of Laysan, currently has the most restricted range of any duck in the world (4). It is a small, dark duck with orange legs and a prominent white eye-ring. The amount of white around the eye and on the head varies between individuals, and some adult males also have a slight green iridescence to the dark head. The rest of the plumage is dark reddish brown plumage, heavily mottled dark brown, and an iridescent patch of colour on the wings, (the speculum) appears teal green, or blue. Male Laysan ducks have dark green bills, while the female’s is brownish-pale (5) (6).
