Why are flamingos really so pink and why their colour can suddenly fade

Flamingo's vibrant pink and red plumage is a direct result of their diet, rich in carotenoids from algae and crustaceans. This coloration is further enhanced by cosmetic secretions during preening, acting as both decoration and protection against sunlight. Changes in feather brightness signal the health of their wetland habitats and influence social and mating success.
