Flamingos aren't pink in the wild. They are a special combination of food to make them pink for zoos and parks. Just ask Jack Hannah. Phoenix myth, I think not.
well... flamingos actually are pink in the wild, and they gain that colour by eating lots of those little red crabs that are their favourites and live in the waters where they live. or at least that's what i heard...
