WebMetabolism. Birds are endothermic meaning they have ability to maintain a relatively stable body temperature, irrespective of the ambient temperature. Their body temperature is about 3 degrees higher than mammals at around 40°C (+/- 1.5°C) so high metabolic rates are needed to maintain this and enable them to fly.
