Bewick's swans are called 'small swans' in Dutch. Even though they are big birds, they are smaller than mute and whooper swans. Bewick's swans have more than 25,000 feathers on their body, providing excellent insulation when they are in northern Russia where they nest. They move south in the winter, where the grass is more tender than the withered tundra grass hidden under the snow. This swan is named after the illustrator Thomas Bewick.
