The barnacle pintail, or the Bahamian pintail, or the Bahamian pintail, is a true duck of the Caribbean, South America and the Galapagos Islands.
Very similar to southern ducks, the sexes are the same. Mostly brown with white cheeks and red base of gray beak, young birds are slightly pink. Cannot be confused with other ducks in this range.
This species was first described by Linnaeus in his Systema naturae in 1758, published under his real scientific name.
Forms 3 subspecies:
- Anas bahamensis - Caribbean islands, roams in South Florida,
- Anas bahamensis galapagensis - Galapagos Islands,
- Anas bahamensis rubirostris - South America: from southern Ecuador and southern Brazil to northern Chile and northern Argentina.
The latter subspecies may have a tendency to migrate, breed in Argentina, and winter further north.
