Certain bacteria in water, if that bacteria isn't in the water then they stay white. So I don't really think of flamingos as just pink anymore. I know about this stuff I live in Florida. Sorry DeanaWynn but you are wrong.
Flamingo feathers obtain their wonderful rosy pink color from pigments in the organisms they eat. The flamingos’ feathers, legs, and face are colored by their diet, which is rich in alpha and beta carotenoid pigments. Carotenoids in crustaceans such as those in the flamingo diet are frequently linked to protein molecules, and may be blue or green. After being digested, the carotenoid pigments dissolve in fats and are deposited in the growing feathers, becoming orange or pink. The same effect is seen when shrimp change color during cooking. The amount of pigment laid down in the feathers depends on the quantity of pigment in the flamingo’s diet. An absence of carotenoids in its food will result in new feather growth that is very pale; the existing pigment is lost through molting.
