WHY ARE FLAMINGOES PINK? by requestBathing FLAMINGO©Chi Liu
There are six different species of flamingo, found in locations ranging  from the Caribbean and South America to Africa, India, and the  Mediterranean and they range in color from light pink to nearly crimson.
Flamingo feathers obtain their wonderful rosy pink color from  pigments in the organisms they eat. The flamingos’ feathers, legs, and  face are colored by their diet, which is rich in alpha and beta  carotenoid pigments.
Carotenoids in crustaceans, or Spirulina that make up the flamingo diet are  frequently linked to protein molecules, and may be blue or green. After  being digested, the carotenoid pigments dissolve in fats and are  deposited in the growing feathers, becoming orange or pink. The same  effect is seen when shrimp change color during cooking. The amount of  pigment laid down in the feathers depends on the quantity of pigment in  the flamingo’s diet. An absence of carotenoids in its food will result  in new feather growth that is very pale; the existing pigment is lost  through molting.
Spirulina, a blue-green algae abundant in the waters  of Lake Natron, makes up lesser flamingoes’ entire diet. Although  called blue-green, this particular algae provides the red pigment for  flamingoes’ feathers. Lesser flamingoes, who survive solely on  Spirulina, have a more intense pink color than greater flamingoes, who  get their lighter color second-hand from their prey, creatures who have  themselves digested the organism.
