在鸟类选择夜间栖息地方面潜在重要的热因素包括避风、局部气温升高和辐射平衡的改善。我分析了这三个因素的相对重要性，使用数据描述的温度关系ofPhainopepla nitens和气象特性的冬季栖息地选择这个物种。与辐射平衡的改善相比，避免强制对流提供了大约5倍的热效益。可能的代谢加热的鸟的栖息地内的空气是不重要的。
Thermal factors potentially important in the selection of nocturnal roosts by birds include shelter from wind, local increases in air temperature, and improvement in radiation balance. I analyze the relative importance of these three factors using data describing the thermal relations ofPhainopepla nitensand the meteorological properties of winter roost sites selected by this species. Shelter from forced convection provides approximately 5 times more thermal benefit than improvement of radiation balance. Possible metabolic heating by the bird of air within the roost site is unimportant.
