What ensures the birds have a high and constant body temperature?

The body temperature of birds is high (38-43.5 ° C) and constant. This is achieved by a high intensity of nutrition, rapid digestion of food, supplying all cells of the bird’s body with a sufficient amount of oxygen, which is used to generate energy in them. Some of the energy is converted into heat, which is stored in the bird’s body by its feathers.
