Which physiological response occurs in soaring birds during prolonged flight, impacting their metabolic rate?

💡 Explanation

During prolonged soaring flight, birds utilize lipid metabolism to minimize weight and efficiently extract energy; lipolysis increases as glycogen stores deplete, leading to ketone body production influencing metabolic rate for extended soaring periods. Therefore ketone bodies result, rather than gluconeogenesis, uric acid increases, or blood cell concentration increases, requiring different metabolic conditions.
