Why Are Flamingos Pink?

Flamingos are not born with pink feathers; their color comes from their diet, rich in carotenoids found in algae and shrimp. These pigments are processed in the flamingo's body, turning their feathers pink over time. A similar process occurs in lobsters and shrimp when cooked. Humans can also experience skin color changes from consuming carotenoid-rich foods, a condition known as carotenosis.
