Infrared Swan

A swan has much thinner feathers on its neck and face than on the rest of its body allowing more heat loss from these areas. The swans beak also glows brightly in the infrared. Notice how bright the swan's neck and face are compared to the heavily feathered part of its body - even though much of the swan's body is above water and in the sunlight. Being warm-blooded, swans try to maintain a constant body temperature. When they get too warm, they can cool off in the water. Swans will migrate to warmer areas in the winter to keep from getting too cold.
