To photograph the swans in their environment meant I had to endure the same conditions - snowstorms and high winds that roll the snow across the flat land in great waves. The storm was so bitter I wished I could have escaped along with the swans. Every winter, huge flocks of whooper swans migrate from the far north of Europe and Asia to warmer lowlands. The Rongcheng Swan Lake nature reserve in eastern China is a major overwintering sanctuary for whooper swans. But even here, when the fresh water freezes, the birds are forced to feed in the fields, digging through the snow for grass.
