Why Are Flamingos Pink? Diet, Feathers & Facts

Flamingos are pink because of carotenoid pigments in their food — brine shrimp and algae. Chicks hatch grey-white; colour builds with diet.

Quick answer

Flamingos get their pink and orange colour from carotenoid pigments in algae and the small crustaceans that eat those algae. Without those pigments in the diet, feathers fade toward white or pale. Chicks are greyish-white and gain colour as they feed.

Flamingos are pink because of carotenoids in their food — not because they are born that colour.

Pigment pathway

Algae produce carotenoids → shrimp and other prey concentrate them → flamingo liver metabolises pigments → feathers, skin, and egg yolks take on pink/orange hues.

Species note

Greater, lesser, Chilean, Andean, James’s, and American flamingos vary in intensity, but the dietary mechanism is shared.

Frequently asked questions

Are flamingos born pink?

No — chicks are grey-white and turn pink over months to years with diet.

What do flamingos eat?

Filter-fed algae, diatoms, and small invertebrates such as brine shrimp.

Can zoo flamingos lose their colour?

Yes — if diets lack carotenoids; zoos supplement to keep plumage vivid.

Why do flamingos stand on one leg?

Likely to conserve heat and reduce muscle fatigue — still studied, but energy-saving is the leading explanation.
