American bison de-frosting, by Mervin D Coleman, USA. One bitterly cold morning in Yellowstone National Park, Mervin came across three bison by the side of the road. The sun was beginning to peek over the ridge, silhouetting one of them. "As steam began to rise from its frost-covered body, it added moisture to the air, creating a prism of colours," Mervin said. It was a magical, almost spiritual moment. Picture: Mervin D Coleman / Wild Planet
