摘要: 根据已发表的文献和资料,对广西繁殖鸟类资源进行了整理分析。截至目前,广西共有繁殖鸟类20目67科428种,主要由347种留鸟构成(占81.07%)。列入国家I级保护动物的有金雕(Aquila chrysaetos)、黄腹角雉(Tragopan caboti)、白颈长尾雉(Syrmaticus ellioti)和黑颈长尾雉(Syrmaticus humiae)4种;列入国家Ⅱ级保护动物的有68种。列入IUCN红色名录的有20种,包括2种濒危(EN)、8种易危(VU)和10种近危种(NT)。区系上,东洋界种类最多(77.34%),广布种次之(15.42%),古北界种最少(7.24%)。在繁殖鸟中,有89.02%的鸟类偏好于林地生境,其中72.43%属东洋界鸟类,而古北界和广布种鸟类生境偏好则相对多样。在桂西南喀斯特地区和桂南沿海地区,繁殖鸟类非常丰富,其种类分别占整个广西繁殖鸟类的82.24%和61.21%。因此,建议在优先保护这两个地区的基础上,加强保护区外、尤其是林区生境的保护。

Abstract: Species richness and composition of breeding birds in Guangxi Province were evaluated based on the publications and field records (updated to 2015). A total of 428 breeding species were recorded in Guangxi Province, which belong to 20 orders and 67 families. 81.07% of them are residents (347 species). Aquila chrysaetos, Tragopan caboti, Syrmaticus ellioti and S. humiae are listed as grade I national protected species in China. Sixtyeight species are listed as grade Ⅱ national protected species. Twenty species are listed in the IUCN Red List, including 2 Endangered, 8 Vulnerable and 10 Near Threatened. More species were found in Oriental realm (77.34%) than in Palearctic realm (7.24%) and in both realms (15.42%). 89.02% species, mostly Oriental species (72.43%), prefer woodland, whereas species in Palearctic realm and both realms are generalists. A high number of species were found in southwestern Guangxi and coastal area of southern Guangxi, and accounted for 82.24% and 61.21% of all breeding species in the province, respectively. Thus, these areas, particularly woodland habitats, should be considered with conservation priority.
