Thermoregulation in birds

Webb13 apr. 2024 · Another important reason for birds to dry their wings is to regulate their body temperature. Wet plumage can affect their thermoregulation, making it difficult for them to maintain an ideal body temperature. Some birds, such as cormorants, use spread-wing postures for drying their wings and not for thermoregulation when wet. WebbThermoregulation is a dynamic, homeostatic interaction between an organism’s internal processes and its external environment, to maintain a stable, physiological temperature. …

Webb11 apr. 2024 · The result suggests that a large nasal cavity accommodating a well-developed respiratory turbinate is primarily important as a thermoregulation apparatus for large brains characteristic of endothermic birds and mammals, and the nasal cavity of Velociraptor was apparently not large enough to carry out this role required for an … WebbThermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. Webb5 apr. 2024 · Using Infrared Thermography (IRT), thermoregulation of Asian elephants at low ambient temperatures was examined.
