Detailed explanation-1: -Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment.
Detailed explanation-2: -Mammals and birds are called endotherms. An endotherm is an animal that can control its internal body temperature. Endotherms’ body temperature is usually much warmer than the temperature of the environment and usually stays about the same temperature. Endotherms are called “warm-blooded” animals.
Detailed explanation-3: -Most birds are homeothermic, normally maintaining their body temperature within a range of less than 1 °C (1.8 °F) by active metabolic means. However, some small birds are heterothermic, in that they allow their nocturnal body temperature to drop by as much as 10 °C (18 °F).
