Laysan Duck/Laysan Teal Anas laysanensis

The Laysan duck, also called Laysan teal, used to be widespread over islands of Hawaii before the arrival of people, rats and rabbits.

Critically endangered and now native only to one lake on Laysan island in Hawaii, the Laysan duck now breeds mainly in captivity but is being reintroduced in the wild on two more Hawaiian Islands.

Males have dark or bluish bills with black blotches; females have yellowy orange bills with black blotching. Both have white feathers around the eyes.

Males have brighter orange legs. Older ducks have more white feathers on their heads.

The speculum (wing bar) is bluish green bordered with white. There is sometimes slight green iridescence on the head from the ancestor of the Mallard from which Laysans are believed to be descended.
