A black flamingo is seen in a salt lake at the Akrotiri Environmental Centre on the southern coast of Cyprus April 8, 2015. The flamingo is thought to have a genetic condition known as melanism, which causes it to generate more of the pigment melanin, turning it dark rather than the usual pink colour.
