WebMetabolic rate. 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. 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 …

WebThe Eurasian griffon vulture ( Gyps fulvus) is a large Old World vulture in the bird of prey family Accipitridae. It may also be known as the Griffon vulture, [4] though it may be used for the genus as a whole. It is not to be confused with the Rüppell's griffon vulture ( Gyps rueppellii) and Himalayan griffon vulture ( Gyps himalayensis ).
