Between about 97°F (36°C) and 113°F (45°C)
- Despite being endotherms (warm-blooded), avian body temperatures range pretty considerably, with averages between about 97°F (36°C) and 113°F (45°C). They can maintain these temperatures using internal processes alone if they stay within a certain range of temperatures known as their thermoneutral zone.

Some desert birds can obtain their water needs entirely from moisture in their food. Some have other adaptations such as allowing their body temperature to rise, saving on moisture loss from evaporative cooling or panting. Seabirds can drink seawater and have salt glands inside the head that eliminate excess salt out of the nostrils.

Normal body temperature is around 37°C(98.6°F), and hypothermia sets in when the core body temperature gets lower than 35 °C (95 °F). Usually caused by prolonged exposure to cold temperatures, hypothermia is usually treated by methods that attempt to raise the body temperature back to a normal range. [3]
Birds are endotherms, which means they maintain a near-constant body temperature by generating heat within the body. Unlike reptiles, which may become inactive for entire seasons, birds must regulate their body temperature using various physiological and behavioral means to remain active every day.
Warm-blooded is an informal term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals ) maintain a stable body temperature by regulating metabolic processes.
Jul 28, 2023 · Birds, like mammals, are warm-blooded. This means they create heat from their bodies instead of relying on their surroundings. In fact, some of the wild birds in your backyard, including robins and blue jays, generate so much internal heat that their normal body temperatures run as hot as 109 degrees Fahrenheit, or 42 degrees Celsius!
Definition of Thermoregulation. Thermoregulation is the process by which birds regulate their body temperature. It is essential for their survival as it allows them to maintain an optimal internal temperature, regardless of external environmental conditions.
During nighttime torpor, body temperature in a Caribbean hummingbird was shown to fall from 40 to 18 °C, with heart and breathing rates slowing dramatically (heart rate of roughly 50 to 180 bpm from its daytime rate of higher than 1000 bpm).
