White-cheeked Pintail
Anas bahamensis
Like many southern ducks, the sexes are similar, though females are slightly smaller and duller in plumage. It is mainly brown with white cheeks and a red-based grey bill; juveniles have duller bill. The wing has an iridescent green speculum. Like the other pintails, it has a slender, acutely pointed tail, though not so marked as in the northern pintail A. acuta. It cannot be confused with any other duck in its range.
