Bright, bold, and beautiful—bird feathers are some of nature’s most fascinating works of art.
Clark went around the world, from China to Austria, to chronicle the dazzling evolution of plumage. He mined feather collections to photograph hundreds of feathers in various colors and patterns. (Read "Feathers of Seduction" in National Geographic magazine.)
For Clark, the draw of feathers is more than skin-deep.
“They’re beautiful for sure,” he says. “To me, what makes them beautiful is their function—their functionality has created their form, so I find that fascinating.”
