Hawaiian Duck
Anas wyvilliana
Native Range:
Pacific Ocean Region
Notes:
a close relative of the Mallard Duck, with which it sometimes hybridizes; unlike the Mallard Duck, this species is not sexually dimorphic, and both sexes look quite like drab female mallards; a rare and secretive bird usually found in pairs or small groups.
