近年来中国鸟类野外新纪录的解析

过去若干年里,在中国记录的野生鸟类物种数一直处于增长之中,特别是在2005年《中国鸟类分类与分布名录》第一版出版之后到2013年,又有多个中国鸟类新记录被发现。有部分新纪录已经被收录到2011年出版的《中国鸟类分类与分布名录》第二版之中,但一些新纪录在中国的记录状况、分布等信息还不为广大鸟类学工作者所熟知。本文对这些纪录的分类、分布状况进行了系统性总结,在总结的基础上我们发现,在这些新纪录主要分布于三个热点地区,包括西部边境省区(新疆、西藏、云南、广西),沿海三省市(河北、天津、福建)及台湾。其中,出现在西部的新纪录物种的已知分布区邻近中国,部分种类极可能在中国境内繁殖、越冬和过境;而来自沿海和台湾的新纪录物种原有分布区距离中国较远,在中国多为偶见的迷鸟。未来这些地区仍将是产生中国新纪录的热点地区。

On An Update of Recent New Bird Records in China

The number of wild bird species in China has been increasing steadily since last few years. This increase is partially as a consequence of recent findings of new species which have not previously been recorded in the Chinese territory. We hereby designated 43 new recorded bird species in China through reviewing literatures and field records, which were recently discovered after the publication "A Checklist on the Classification and Distribution of Birds in China" in 2005 and its second edition in 2011 or not included therein. Hereby, we review the taxonomy and status of distribution of these new species. We identified three geographically hotspots where those new records were from, including four provinces at the Chinese border (Xinjiang, Tibet, Yunnan and Guangxi), three Chinese coastal provinces (Hebei, Tianjin and Fujian) and Taiwan. The first region comprised new recorded species distributed in neighboring countries, these birds might breed, migrate or winter in China. The new recorded species in the latter region are mainly straggler birds, whose distribution ranges are distant from China.
