| 摘 要： | 为系统地研究北京地区雨燕科3种雨燕的羽毛特点,给雨燕科的保护、分类研究积累资料,笔者对北京地区分布的雨燕目(Apodiformes)雨燕科(Apodidae)的白腰雨燕(Apus pacificus)、普通楼燕(Apus apus)、白喉针尾雨燕(Hirundapus caudacutus)主要类型羽毛进行微观结构对比观察。试验流程为:鸟类标本取样前再鉴定、确定采样位置、取样、样品脱脂、超声波清洗、自然干燥、离子溅射喷金及扫描电子显微镜观察。结果表明:飞羽、尾羽和体羽主要有钩羽小枝和无钩羽小枝构成;有钩羽小枝和无钩羽小枝相互啮合形成坚实的羽面来减少飞行阻力。3种鸟类羽毛的飞羽羽小轴表面纹饰、绒羽节点形状可以作为属间分类重要特征,飞羽、尾羽及体羽其他特征参数可以作为参考。

| Abstract: | The paper aims to systematically study the characteristics of 3 kinds of swifts’ feathers in Apodidae from Beijing, so as to provide data for the protection and classification of Apodidae. We compared and observed the microstructures of feathers from Apus pacificus, Apus apus and Hirundapus caudacutus in Apodidae, Apodiformes from Beijing. The following steps were carried out: re-identification, confirming the sample location, sampling, degreasing, ultrasonic cleaning, drying in natural condition, ion sputtering, and SEM observation. The results showed that: the remiges feathers, rectrices feathers and downy feathers were mainly composed of distal barbules and proximal barbules, these barbules formed a flexible and strong vane to reduce the air resistance. The surface ornamentation of small shaft from remiges feathers, the shape of nodes from 3 kinds of feathers of Apus pacificus, Apus apus and Hirundapus caudacutus could be used as an important feature of inter-species classification, and the other feature parameters of feathers could be used as references. |
