Bird thermoregulation
WebApr 10, 2024 · Chicks of precocial birds hatch well-developed and can search actively for food but their homeothermy develops gradually during growth. This makes them dependent on heat provided by parents (“brooding”), which is then traded off against other activities, mainly foraging. Although brooding has been documented in many precocial birds, little … WebMechanisms of thermoregulation. As a refresher, animals can be divided into endotherms and ectotherms based on their temperature regulation. Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different …

The amount of energy expended by an animal over a specific period of time is called its metabolic rate. Metabolic rate may be measured in joules, calories, or kilocalories per unit time. You may also see metabolic rate given as oxygen consumed (or carbon dioxide produced) per unit time.
