Flamingos or flamingoes are a type of wading bird in the genus Phoenicopterus the only genus in the family Phoenicopteridae. There are four flamingo species in the Americas and two species in the Old World.
Six flamingo species are recognized by most sources, and these are generally placed in one genus. Two species, the Andean and the James’s Flamingo, are often placed in the genus Phoenicoparrus instead of Phoenicopterus. A wide variety of birds have been proposed as their closest relatives, on a wide variety of evidence. As a result, flamingos are generally placed in their own order.
Traditionally, the long-legged Ciconiiformes, probably a paraphyletic assemblage, have been considered the flamingos’ closest relatives and the family was included in the order. Usually the ibises and spoonbills of the Threskiornithidae were considered their closest relatives within this order. Earlier genetic studies, such as those of Charles Sibley and colleagues, also supported this relationship.Relationships to the waterfowl were considered as well,especially as flamingos and waterfowl are parasitized by feather lice of the genus Anaticola, which are otherwise exclusively found on ducks and geese.Other scientists proposed flamingos as waders most closely related to the stilts and avocets, Recurvirostridae. The peculiar presbyornithids were used to argue for a close relationship between flamingos, waterfowl, and waders, but they are now known to be unequivocal waterfowl with a peculiarly derived morphology paralleling waders and flamingos
