Hooded Merganser

Lophodytes cucullatus

The hooded merganser is a species of fish-eating duck in the subfamily Anatinae. It is the only extant species in the genus Lophodytes. The genus name derives from Greek: lophos meaning 'crest', and dutes meaning 'diver'. The bird is striking in appearance; both sexes have crests that they can raise or lower, and the breeding plumage of the male is handsomely patterned and colored. The hooded merganser has a sawbill but is not classified as a typical merganser. Source
