The Pintail Duck, or Northern Pintail (Anas acuta), is a medium to large sized migratory duck that gets its name from the long tail feathers found on the male of the species, which may measure up to 1/4 of the Pintail Drake's overall length. Northern pintails are long, slender ducks with long, narrow wings, earning them the nickname greyhound of the air. Pintails are named for their elongated central tail feathers, which constitute one-fourth of the drake's body length.
The white-cheeked pintail (Anas bahamensis), also known as the Bahama pintail or summer duck, is a species of dabbling duck. It was first described by Linnaeus in his Systema naturae in 1758 under its current scientific name.
