Flamingos are gregarious wading birds in the genus Phoenicopterus and family Phoenicopteridae. They are found in both the Western Hemisphere and Eastern Hemisphere, but are more numerous in the former. There are four species in the Americas while two exist in the Old World. Two species, the Andean and the James’s Flamingo, are often placed in the genus Phoenicoparrus instead of Phoenicopterus.
