白冠攀雀的形态鉴定及其在中国的分布

Morphological identification and distribution of the White-crowned Penduline Tit in China

2018年之前,白冠攀雀(Remiz coronatus)在中国的已知分布范围仅限于新疆和宁夏北部.随着我国观鸟爱好者数量的增加,有人陆续在甘肃、陕西、内蒙古等地拍摄到了白冠攀雀.但由于白冠攀雀的形态特征与中华攀雀(R.consobrinus)有很多相似之处,科研人员和观鸟爱好者在野外观察过程中难以准确鉴定该物种,被误认的现象时有发生.为此,本文根据野外实地考察并参考相关文献资料,对白冠攀雀的形态特征及其与中华攀雀的差异进行了详细描述;并对其在中国的分布现状进行了更新.结果显示,白冠攀雀指名亚种(R.c.coronatus)为我国新疆西北部的夏候鸟;stoliczkae亚种为新疆北部的夏候鸟,新疆南部的冬候鸟,宁夏的夏候鸟和冬候鸟,甘肃、内蒙古和陕西的冬候鸟.

Prior to 2018,known distribution of the White-crowned Penduline Tit(Remiz coronatus)in China was limited to Xinjiang and northern Ningxia.The emergence of Chinese bird-watchers has resulted in more records of the bird in Gansu,Shaanxi and Inner Mongolia.However,the similar morphology of White-crowned Penduline Tit and Chinese Penduline Tit(R.consobrinus)often prevents accurate identification of these 2 species in the field,misidentification occasionally occurred.Morphological characteristics of White-crowned Penduline Tit and differences from Chinese Penduline Tit were described in this work in detail.Distribution status of White-crowned Penduline Tit in China was summarized:the nominate subspecies is a summer visitor in northwest Xinjiang,the stoliczkae subspecies is a summer visitor in northern Xinjiang,a winter visitor in southern Xinjiang,a summer visitor and wintering visitor in Ningxia,and a wintering visitor in Gansu,Inner Mongolia and Shaanxi.
