Chilean flamingos live in shallow brackish salt water lakes, coastal estuaries, and lagoons. Their geographic range includes central Peru, and south along the Andes to Tierra del Fuego.
In the wild, flamingos eat algae, crustaceans, brine shrimp, diatoms and aquatic plants. At the Zoo, a special “flamingo fare” (a nutritionally balanced diet with a texture like soup) is served.
