Flamingos are born with grey feathers that turn into pink over time as a result of their diet. Their diet consists of brine shrimp, algae, and other small crustaceans that contain pigments called carotenoids, which color their feathers. The more carotenoids they consume, the deeper the pink color of their feathers.
