A look at birds through slow-motion cameras and aerial photography reveals some of the extraordinary things feathers allow them to do.
Birds descend from dinosaurs who developed feathers. Those allow most of them to fly, which few other vertebrates can. Some birds gave up flying, like penguins, who specialize in diving and prove feather's fabulous insulating efficiency. Feathers are also key to courting, almost as varied as bird physiognomy and ways of solitary or social life almost all over the globe.—KGF Vissers
