Thermoregulation in Aves
Like some electrical appliances, the body also has a "thermostat" to help keep the temperature constant. This is known as the Hypothalamus. This heat controlling centre is particularly sensitive to two types of stimuli. These are changes of temperature of the blood and a series of impulses from the aprts of the skin that are exposed to the aterered temperature of the surroundings.
As soon as the temperature of the surrounds drop, the body tends …showed first 75 words of 426 total…

Sweat plays an important role in temperature regulation. In cold weather sweat gland activity is limited.
Panting also helps the body to regulate temperature. Expired air is warmer then inspired air. The expiration of water vapour increases the rate of evaporation in the lungs. The faster the breathing rate, the greater the heat loss.
