“The mix of different colours on this bird’s feathers emphasises how important the sense of vision is to birds. The vibrant yellows and oranges are created by pigments in the feathers, while the blues are formed by the scattering of light by air channels in the feather. The greens are formed by a combination of these mechanisms,” says Elphick.
“Because birds see a wider range of colours than humans, this bird may look even more spectacular to a potential mate than it does to us.”
