动物已经进化出多种适应性来照顾它们的身体表面，例如梳理行为，这可以保持外皮清洁、无寄生虫和适当的排列。尽管对哺乳动物、鸟类和节肢动物的梳理进行了广泛的研究，但梳理的生存价值从未在自然种群中直接测量过。我们监测梳理和生存的人口标记美国红隼（隼sparverius）的圣萨尔瓦多岛，巴哈马群岛。我们发现花在梳理上的时间和2年内的生存率之间有很强的关联。二次关系，我们显示是一致的，稳定的自然选择梳理时间。据我们所知，这是第一个证据，梳理时间和自然种群的生存之间的相关性。梳理时间可以预测许多动物类群的生存，但需要更多的研究来确定鸟类，哺乳动物和节肢动物之间的关系的形状和强度。
Animals have evolved a variety of adaptations to care for their body surfaces, such as grooming behavior, which keeps the integument clean, parasite-free, and properly arranged. Despite extensive research on the grooming of mammals, birds, and arthropods, the survival value of grooming has never been directly measured in natural populations. We monitored grooming and survival in a population of marked American kestrels (Falco sparverius) on San Salvador Island, Bahamas. We found a strong association between time spent grooming and survival over a 2-year period. The quadratic relationship we show is consistent with stabilizing natural selection on grooming time. To our knowledge, this is the first evidence for a correlation between grooming time and survival in a natural population. Grooming time may predict the survival of many animal taxa, but additional studies are needed to determine the shape and strength of the relationship among birds, mammals, and arthropods.
