Nineteen avian species were tested whether they respond to angiotensin II (AII) or not by drinking. Most species responded to intraperitoneally injected AII by drinking, but carnivorous birds and those originating in arid areas were insensitive to AII in drinking. Thus, the dipsogenic effect of AII in birds is different depending on their habitats and diets. It seems that AII-induced drinking mechanism has evolved as a part of thirst mechanisms during the evolutionary adaptive process.
