You can watch flamencos feeding at Los Flamencos Fauna and Flora Sanctuary, located in the town of Camarones, 15 minutes south of Riohacha. There, in an area encompassing 7000 hectares, hundreds of these birds stick their beaks into the estuary of the Camarones River in search of the artemia salina—a species of brine shrimp that give flamingos their pink color.  Flamingos also feed on the larvae of shrimp and other species.
