Migration is one of the most physiologically demanding activities animals perform. This is particularly true for fliers because flight energy expenditure is exceptionally high, flights are maintained for long periods (many hours, but up to 9 days without water, food or rest), and refueling demands high levels of activity and nutrient processing. The allocation of energy and nutrients to migration may impair other functions, such as immunity against diseases or parasites, and conversely, immune or toxic challenges may impede migration. Thus, migration offers an excellent model to study the limits to physiological performance of animals.

迁徙是动物进行的对生理要求最高的活动之一。对于飞行员来说尤其如此，因为飞行能量消耗异常高，航班需要长时间维持(许多小时，但长达9天没有水、食物或休息)，加油需要高水平的活动和营养处理。为迁徙分配能量和营养可能会损害其他功能，如对疾病或寄生虫的免疫力，反过来，免疫或毒性挑战可能会阻碍迁徙。因此，迁徙为研究动物生理表现的极限提供了一个很好的模型。
