National Geographic : 2018 Jun
Male red-winged parrots of Australia, Indonesia, and Papua New Guinea may already look fetch- ing, but females likely perceive an even more vibrant palette. Like many other birds, the species can see ultra- violet light. Some par- rot feathers fluoresce under UV, suggest- ing that the birds use a complex spectrum of light wavelengths to communicate with potential mates. PHOTOGRAPHED AT LORO PARQUE FUNDACIÓN, CANARY ISLANDS, SPAIN THE YEAR OF THE BIRD National Geographic is partnering with the National Audu- bon Society, BirdLife International, and the Cornell Lab of Ornithology to cele- brate the centennial of the Migratory Bird Treaty Act. Watch for more stories, books, and events through- out the year.
