Is it true that flamingos are pink because of shrimp?

Explanation

Shrimp can contribute, but this is an incomplete explanation for flamingos as a group. Their pink and reddish colors come from carotenoid pigments obtained through food, including algae and small crustaceans such as brine shrimp.

The Smithsonian explains that brine shrimp consume microscopic algae containing these pigments. Flamingos obtain and metabolize carotenoids when they eat algae or the shrimp. San Diego Zoo independently identifies algae and crustaceans as dietary sources of the birds' coloration.

Diet differs between species: some flamingos filter very fine foods such as algae, while others eat more invertebrates. San Diego Zoo also maintains its flamingos' coloration with pigment-containing pellets. Shrimp are therefore one possible route for the pigments, not a necessary explanation for every pink flamingo.

Key takeaway

Flamingos get their pink color from dietary pigments that can come through algae or shrimp.

Different species obtain pigments from different foods

San Diego Zoo

Provides context

San Diego Zoo identifies both algae and small crustaceans as pigment sources and describes differences between algae-filtering species and species that eat more invertebrates.

Pigmented pellets also maintain pink coloration

San Diego Zoo

Provides context

The zoo reports feeding its flamingos a formulated pellet diet containing pigment that helps maintain their pink color, showing that shrimp are not required for coloration.
