识别动物个体对于许多类型的生态研究至关重要，因为它可以估计人口参数，如种群规模，存活率和繁殖率。一种流行的方法是利用斑点、条纹或疤痕标记的自然变化来识别个体。虽然有几项研究已经评估了这些方法在哺乳动物、甲壳类动物和鱼类中的准确性，但很少有人试图确定表型特征在用于鸟类时是否准确。此外，关于脱落或蜕皮的身体部位是否可以可靠地用于视觉识别个体，人们甚至知之甚少。在这里，我们评估了使用表型特征来识别鸟类个体的准确性，使用双标记实验，其中9个微卫星遗传标记和脱落羽毛上的天然标记被用来独立地识别北方苍鹰。在94.4%（51/54）的比较中，个体的表型和遗传鉴定是一致的。我们的研究结果表明，脱落羽毛的表型特征可以可靠地用作一种非侵入性和相对廉价的技术来监测一种难以捉摸的物种，北方苍鹰的种群，而不必重新捕获或重新观察个体。我们认为，使用脱落羽毛上的自然标记也将是一种可靠的方法，用于识别具有相似表型特征的鸟类物种，如其他鸟类物种。
The recognition of individual animals is essential for many types of ecological research, as it enables estimates of demographic parameters such as population size, survival and reproductive rates. A popular method of visually identifying individuals uses natural variations in spot, stripe or scar markings. Although several studies have assessed the accuracy of these methods in mammals, crustaceans and fish, there have been few attempts to determine whether phenotypic characteristics are accurate when used for birds. Furthermore, even less is known about whether shed or moulted body parts can be reliably used to visually identify individuals. Here we assessed the accuracy of using phenotypic characteristics to identify avian individuals using a double‐marking experiment, whereby nine microsatellite genetic markers and natural markings on shed feathers were used to independently identify northern goshawksAccipiter gentilis. Phenotypic and genetic identification of individuals was consistent in 94.4% (51/54) comparisons. Our results suggest that the phenotypic characteristics of shed feathers can be reliably used as a non‐invasive and relatively inexpensive technique to monitor populations of an elusive species, the northern goshawk, without having to physically re‐capture or re‐sight individuals. We posit that using natural markings on shed feathers will also be a reliable method of identifying individuals in avian species with similar phenotypic characteristics, such as otherAccipiterspecies.
