Short answer: flamingos turn pink because of carotenoids in their diet. These red, orange and yellow pigments come from foods such as algae and small crustaceans. After digestion and metabolism, pigment molecules are deposited in the birds’ feathers, skin and beaks.
Flamingo chicks are not born pink
Young flamingos hatch with pale gray or white-gray down. Their famous color develops gradually as they eat a carotenoid-rich diet. The exact shade varies with species, diet, age and condition.
It is more complicated than “they eat shrimp”
Brine shrimp can be part of the chain, but the pigment story often starts with algae and other organisms that make or contain carotenoids. Flamingos are filter feeders, so their diet can include algae, tiny crustaceans, seeds and other small aquatic food.
Could a flamingo lose its pink color?
If the diet contains too little of the relevant pigments, the color can fade over time as feathers are replaced. Zoos therefore pay attention to carotenoid content when formulating diets for flamingos.

FAQ
Are flamingos born pink?
No. Chicks hatch with pale gray or white-gray down and develop pink coloration later as dietary pigments accumulate.
Is shrimp the only reason flamingos are pink?
No. Carotenoids can come through algae and other foods as well; small crustaceans are one part of the diet and food chain.
Would a flamingo turn white without carotenoids?
Its coloration can fade if the diet lacks enough pigment, although the exact appearance depends on species, age, molt and overall condition.
