Heating the preoptic region of the house sparrow caused the bird to decrease its metabolism and to decrease its body temperature, whereas cooling that region caused an increase in metabolism and an increase in body temperature. These responses indicate that the preoptic region of birds, like that of other vertebrates, is an important center for thermoregulation.
