A sawbill duck, the hooded merganser (Lophodytes cucullatus) has a crest that, like a fan, can be spread or closed. Females get their own distinctive elegance from their cinnamon crest. It has a narrow, serrate bill like other mergansers. The genus name derives from the Greek language: lophos meaning 'crest', and dutes meaning diver. Hooded mergansers are the second smallest species of merganser, with only the smew of Europe and Asia being smaller, and it also is the only merganser whose native habitat is restricted to North America.
