Flamingos get their signature pink hue by eating shrimp, while boobies feet turn bright blue because of their fishy diets.
But how do parrots get their vivid red, yellow and green feathers? This query has long perplexed scientists, but, now, they say theyre one step closer to solving the mystery.
A simple chemical tweak governed by a single enzyme determines the color of a parrots plumage, researchers report this week in a new paper published in the journal Science. Their findings not only help answer a long-standing question about parrots, but they could also offer broader insights into evolution and color variation throughout the animal kingdom.
It is a huge step forward in avian color genetics, says Rosalyn Price-Waldman, an evolutionary biologist finishing her PhD at Princeton University who was not involved with the research, to NPRs Ari Daniel.

The orange stripes of a tiger would seem to be a disadvantage when they are hunting in dense undergrowth, but most of their prey see orange the same as green, so it actually is the perfect shade to blend in to the background undetected.
