The pink colour is due to a carotenoid pigment, similar to astaxanthin, which is derived from the birds' diet. Flamingos feed on small crustaceans, which they sieve through their specially adapted bills. Large expanses of shallow water often become salty through evaporation in saltings by the sea, as in the Camargue in the south of France, or at high altitudes in the Andes, and in Africa. These expanses of water support brine shrimps (artemia), which can make astaxanthin from the simpler carotenoids contained in the algae on which they feed. In flamingos these pigments dissolve in fats and are deposited in the growing feathers. The amount of pigment laid down depends on the quantity in the food. When the birds moult they lose the pigment, and become quite pale if deprived of a carotenoid-rich diet when new feathers are forming.
