The Greater Flamingo (Phoenicopterus roseus) is the most widespread flamingo of the family Phoenicopteridae which is in the genus Phoenicopterus. It is found in parts of Africa, southern Asia, the Middle East and southern Europe. Sub-adult flamingos are whitish-grey and only attain the pink coloration several years into their adult life. The coloration comes from the carotenoid pigments in the organisms that live in their feeding grounds. Secretions of the urpoygial gland also contain carotenoids. During the breeding season, Greater Flamingos increase the frequency of their spreading of uropygial secretions over their feathers and thereby enhance their colour.
