It’s these pigments that eventually stain a flamingo’s feathers – and that’s not all. So, how are flamingos able to eat these foods without falling seriously ill? Thanks to their specialised metabolism, the birds are able to process these harmful chemicals in the liver, breaking them down into functional components and pigments. All of these can be dangerous to many other animals as they contain toxic chemicals called carotenoids,” explains Dr Paul Rose, zoologist at the University of Exeter. Within this water, however, is an untapped resource of food like crustaceans, cyanobacteria and diatom algae. “Flamingos tend to live in inhospitable, relatively remote wetlands – lakes so alkaline in pH it could burn human flesh off the bones. Well, not at birth, anyway.Īs shown in BBC’s Life In Colour, young flamingos flaunt grey/white colour feathers and only develop their pinkish hue after delving into a diet of brine shrimp and blue-green algae – food that would likely kill other animals.
