温度是调节小鸟产热的重要环境信号。我们验证了一种假设，即一种小型雀形目鸟类，中华白头雀，可以通过减少体重、器官质量以及改变肝脏和肌肉的生理生化过程来减少产热，以应对气温变暖。驯化4周后，驯化至30±1℃时，养殖中华绒毛虫的体质量和基础代谢率(BMR)下降，肝、肾和小肠质量下降，肝脏和肌肉线粒体4态呼吸和细胞色素C氧化酶(COX)活性降低，且BMR与体质量、器官质量(肝、肾、小肠和全消化道)、肝和肌肉中线粒体4态呼吸和细胞色素C氧化酶(COX)活性呈正相关。这些结果表明，体质量、器官质量和呼吸酶活性的变化是中国鳞茎适应较高温度的机制。这些数据支持这样的假设，即这种生理灵活性在鸟类中无处不在。
Temperature is an important environmental cue for the regulation of thermogenesis in small birds. We tested the hypothesis that a small passerine, the Chinese bulbul Pycnonotus sinensis can decrease thermogenesis in response to warmer temperatures by decreasing body mass, the organ mass and changing physiological and biochemical processes in the liver and muscle. Captive Chinese bulbuls decreased in body mass and basal metabolic rate (BMR) during 4 weeks of acclimation to 30±1°C. They also showed a decrease in liver, kidney and small intestine mass and reduced mitochondrial state-4 respiration and cytochrome C oxidase (COX) activity in the liver and muscle compared to 10±1°C. Furthermore, BMR was positively correlated with body mass, organ mass (liver, kidney, small intestine and entire digestive tract), and mitochondrial state-4 respiration and cytochrome C oxidase (COX) activity in the liver and muscle. These results indicate that changes in body mass, organ mass and respiratory enzyme activity are mechanisms by which Chinese bulbuls adapt to warmer temperatures. The data support the hypothesis that such physiological flexibility is ubiquitous in birds.
