Birds, like mammals, are “homeotherms,” which means that they maintain a relatively constant deep-body temperature. Birds are also “endotherms,” a term indicating that they are able to increase their body temperature by generating a considerable amount of heat within their tissues instead of relying on heat gained directly from their surroundings (Whittow, 1966).
