A Study of the Body Temperature of Birds

Abstract

WITH regard to body temperature, animals are divided into two great groups, namely, warmblooded and cold blooded, the former including mammals and birds; the latter reptiles, amphibians, fishes, and all invertebrates. A more accurate distinction than the actual temperature, however, is based on the fact that the so-called warm-blooded animals have a constant temperature (homoiothermal) while the cold-blooded animals have a variable temperature which is practically the same as that of the environment in which they live (poikilothermal).
