Question

Why are flamingos pink?

Answer 1

Flamingos are pink due to the pigments in the algae and small crustaceans they consume as part of their diet. Specifically, they feed on organisms that contain carotenoid pigments, which contribute to their pink coloration. These pigments are absorbed by the flamingos' body and accumulate in their feathers, skin, and even their beaks, resulting in their distinct pink hue. The more carotenoids they consume, the brighter and more vibrant their coloration becomes.
