Why are you pink? Carotenoids from blue-green algae, this bird’s main food source, provides a pinkish hue to its feathers, beak, legs, the eyes- well, just about everything.
The coloured pigments in carotenoids exist in many living things- in plants, they assist photosynthesis and protect the vital chlorophyll elements from damage by the sun. While us humans consume them in foods such as carrots and pumpkin at levels that aren’t quite enough to turn us orange or pink, it is apparently possible… So, pretty in pink, they say. And indeed these graceful birds are- when they’re not giving you a death stare like this one here!
