The Pintail, also called the Northern Pintail to distinguish it from southern species, is native to the northern hemisphere of the Americas, Europe and Asia. It breeds in the north of its range and migrates south to winter.
Only the male, above in breeding plumage, has the long, thin, forked tail that gives the species its name. The brown mallard-like female pintail, below, does not have a long tail.
