About Anas bahamensis Linnaeus, 1758
Like many species of southern ducks, male and female Anas bahamensis have similar appearances, though females are slightly smaller and have duller plumage. This species is primarily brown, with white cheeks and a grey bill that has a red base; juvenile individuals have a duller bill. The wing features an iridescent green speculum. Like other pintail ducks, it has a slender, sharply pointed tail, though this pointed shape is less prominent than it is in the northern pintail, Anas acuta. No other duck species found within its range can be confused with this species.
Anas bahamensis is distributed across the Caribbean, South America, and the Galápagos Islands. It is commonly found on waters with some level of salinity, including brackish lakes, estuaries, and mangrove swamps, but it also lives on freshwater pools and lakes. It most often occurs in coastal lowlands, but the subspecies A. b. rubrirostris can be found at elevations as high as 2,550 m in Bolivia.
