| 摘 要： | 棕头鸦雀的分类有过几次较为系统的整理研究。因其飞羽外缘有栗红色与褐色两种类型,前者又可分为红胸、灰胸两类群,故在分类上各学者持有不同意见。或将其分为3个种,或归并为1种。本文依据作者工作结果,从地理分布、形态及骨骼性状进行分析研究,认为棕头鸦雀具栗红翅缘的红胸、灰胸两类群在中国西南地区的云、贵、川三省的亚种分布接触地带彼此混交并有居间个体,不应独立为两个不同种。栗红翅缘褐色翅缘两大类群尚未发现重叠分布,形态明显间断,一直未见有中间类型。两大类群在头骨的泪骨突起和方骨形态上有明显差异,建议将它们分为Paradoxornis webbianus和paradoxornis brunneus。前者再分为红胸、灰胸两亚种组。对少数有争议的亚种也提出了处理意见。

| Abstract: | There were several systematic studies of Rufous-headed Crowtit (Parado-xornis webbianus). One was undertaken by Deignan (1964) , then by Tray-lor (1967) and recent one by Zheng Zuoxin (1984). Rufous-headed Crowtit have brown-winged and red-winged forms. The latter can farther be divided into ashy-throat and vinous-throated groups. So some ornithologists separated the birds" into three species, other ornithologists incorporated all Rufous-headed Crowtits in one specied. The present paper studied geographical distribution, characteristics of skins and comparison of skull. A.mong red-winged forms, ashy-throated and vinous-throated groups' patterns connected by ganluoensis, a new subspecies was fund in Sichuan (Li Guiyuan and Zhang Qinmu 1980) . Both the groups meet in Yunnan, Sichuan and Guizhou Provinces and intermediary individuls were fund in these areas. So ashy-throated and vinous-throated groups should not be separated into difference species. Brown winged and red-winged forms are isolated by geography. There are none of intermedium forms to be fund. The two groups have remarkable differenced in wing colour. There are also differnccs in the shape of process of lachrymal and orbital process of quadrates between brown-winged and red-winged forms. It is considered that Rufous-headed Crowtits should be separated into Paradoxornis brunneus and Paradoxornis webbianus. The latter can be divided into subspecies groups. |
