The greater flamingo (Phoenicopterus roseus) is the most widespread species of the flamingo family. It is found in parts of Africa, southern Asia (Bangladesh and coastal regions of Pakistan and India), and southern Europe (including Spain, Albania, Turkey, Greece, Cyprus, Portugal, Italy and the Camargue region of France).
