摘要:

[目的]对北海市鸟类资源进行全面调查分析。[方法]于2005-2016年对广西壮族自治区北海地区的鸟类进行调查,结合查阅历史资料文件记载,归纳总结全市的鸟类资源。[结果]在北海地区共记录鸟类455种,留鸟种类均较少,多数鸟类在北海为候鸟,其中国家一级重点保护鸟类3种,数量均极为稀少,国家重点保护动物69种,包括数量众多的隼形目猛禽。[结论]北海是西伯利亚、东亚、东北亚候鸟迁往西太平洋群岛、东南亚、南亚以及非洲大陆的重要通道和停歇地。北海地区候鸟数量众多,但由于内陆和滨海湿地退化,以及盗猎野生鸟类行为导致大型水鸟在该地区缺失。因此需在春秋两季迁徙季节加强候鸟保护工作。

Abstract:

[Objective] Complete survey and analysis of bird resources in Beihai City were conducted.[Methods] A survey of birds in Guangxi Beihai region was carried out from 2005 to 2016.Combined with historical records, the bird resources of the city were summarized.[Results] A total of 455 species of birds were recorded in the Beihai region, and there were fewer species of resident birds.Most of the birds were migratory birds in this region, including 3 species of the first class of national key protected birds.The numbers were extremely rare and there were 69 species of national key protected animals, including numerous raptors.[Conclusion] Beihai is an important passage and stopover for those birds which migrate from Siberia, East Asia and Northeast Asia to the Western Pacific Islands, Southeast Asia, South Asia, and the African continent.There are a large number of migratory birds in the Beihai region, but the degradation of inland and coastal wetlands and the poaching of wild birds have resulted in the loss of large water birds in the area.Therefore, it is necessary to strengthen the protection of migratory birds during the spring and fall seasons.
