摘　　要：鸣唱具有吸引异性和驱赶同性的功能,受到性别间选择和性别内选择的共同影响。在少数鸟类中,不同的句子或同一句子的不同部分分别侧重执行吸引异性和驱赶同性的功能,句子的结构也相应的出现了分化。该研究于2011年繁殖季对北京小龙门地区32只北红尾鸲(Phoenicurus auroreus)的鸣唱分析发现,其鸣唱的句子可以分为差异显著的两个部分:稳定部分和可变部分。这两个部分的语图相关变量在均值和变异系数上均有显著差异(配对样本t-检验,P<0.05)。其中稳定部分在个体内非常保守,而可变部分个体内存在较大的变化。在指出句子结构分化的基础上,利用北红尾鸲鸣唱的稳定部分进行个体识别,获得了较高的正确率。Bird song has two key functions： attraction and competition. The structures of these songs have been shaped by both intra- and intersexual selection. Accordingly, there are some species that appear to use different parts of song to attract females and repel males. Alongside this ftmctional separation, the structure of song can also have significant divergence. We studied the songs from 32 individuals of Phoenicurus auroreus, recorded in Beijing Xiaolongmen forest Park during the 2011 breeding season. The song of Phoenicurus auroreus consists of two distinct parts, a stereotyped and variable part. Significant differences between these two parts were observed between all the variables we measured. Based on the stereotyped part, the rate of correct individual identification is satisfactory, and most of songs can be correctly classified.
