The anhinga (/ænˈhɪŋɡə/; Anhinga anhinga), sometimes called snakebird, darter, American darter, or water turkey, is a water bird of the warmer parts of the Americas. The word anhinga comes from the Brazilian Tupi language and means devil bird or snake bird. When swimming the origin of the name snakebird is apparent: only the colored neck appears above water so the bird looks like a snake ready to strike. They do not have external nares (nostrils) and breathe solely through their epiglottis.
The anhinga is placed in the darter family, Anhingidae, and is closely related to Indian (Anhinga melanogaster), African (A. rufa), and Australian (A. novaehollandiae) darters. Like other darters, the anhinga hunts by spearing fishes and other small prey using its sharp, slender beak.
Anhinga species are found all over the world in warm shallow waters. The American anhinga has been subdivided into two subspecies, A. a. anhinga and A. a. leucogaster, based on their location. A. a. anhinga can be found mainly east of the Andes in South America and also the islands of Trinidad and Tobago. A. a. leucogaster can be found in the southern United States, Mexico, Cuba, and Grenada. A fossil species Anhinga walterbolesi has been described from the Late Oligocene to Early Miocene of Australia.
The darters or snakebirds are mainly tropical waterbirds in the family Anhingidae having a single genus Anhinga. There are four living species, three of which are very common and widespread while the fourth is rarer and classified as near-threatened by the IUCN. The term "snakebird" is usually used without any additions to signify whichever of the completely allopatric species occurs in any one region. It refers to their long thin neck, which has a snake-like appearance when they swim with their bodies submerged, or when mated pairs twist it during their bonding displays. "Darter" is used with a geographical term when referring to particular species. It alludes to their manner of procuring food, as they impale fishes with their thin, pointed beak. The American darter (A. anhinga) is more commonly known as the anhinga. It is sometimes called "water turkey" in the southern United States for little clearly apparent reason; though the anhinga is quite unrelated to the wild turkey, they are both large, blackish birds with long tails that are sometimes hunted for food.
I spent my life twenty years in the basin
My only friend was a man of much more
He lied with power in his weary eyes 'till day came
And all at once I knew his name
Giles of the river...comin' in to make my precious day
Giles of the river...comin' in to tell one tale and take
My breath away...and he's on his way
He took me down through good times late departed
And through the world as it was and will be
By bad self I watched you as you hung your head out my door
But you won't grieve me no more
