Shimmering Close-Up Shots Of Peacock Feathers Reveal Amazing Detail

Waldo Nell, a Canadian software engineer and photographer, captured the feathers of a peacock magnified over 500 times. Not least are they beautiful photographs, they also reveal some of the science behind the iridescent glow of a peacock’s plumes.

From green to golden to blue and indigo, the photographs reveal the mix of colors that give peacocks their distinctive appearance. But the actual pigmentation of the feathers only plays a part in peacocks’ coloring. Much of it comes from small nanostructures on their feathers’ barbules, which give them an iridescent shimmer.

As the direction of light changes, these different facing barbules reflect the light at different angles, resulting in the feathers appearing to change color and shimmer as they move. You can also see this effect on butterfly wings, beetle shells and other birds such as hummingbirds. (Source)
