滇池湿地的鸻鹬类及铁嘴沙鸻和弯嘴滨鹬云南新分布

Shorebirds in Wetlands of Dianchi Lake and New Records of Birds in Yunnan:Charadrius leschenaultia and Calidris ferruginea

2012年1月至2013年5月在滇池湿地34个样点上开展了每月1次(共17次)的鸟类调查。迄今为止,滇池湿地共发现鸻鹬类850只次,隶属于5科11属20种。其中,铁嘴沙鸻Charadrius leschenaultia和弯嘴滨鹬Calidris ferruginea为云南鸟类新分布;水雉Hydrophasianus chirurgus和蒙古沙鸻Charadrius mongolus为滇池鸟类新纪录。有18种(731只次)鸻鹬类集中分布在滇池整治过程中形成的福保湾湿地。福保湾湿地大面积浅水泥滩、开阔水域和稠密植被,交错形成了鸻鹬类偏好的生境格局,是导致3种鸻鹬类新分布和大量鸻鹬类个体集中分布的主要原因。

An ornithological survey was carried out monthly in 34 sampling sites located in wetlands around Dianchi Lake, SoUthwest China, from January 2012 to May 2013. A total of 850 shorebirds individuals belonging to 20 species, 11 genera and 5 families were recorded. Especially, greater sand plover （ Charadrius leschenaultia） and curlew sandpiper （ Calidris ferruginea） were found to be the new bird records in Yunnan province, and pheasant-tailed jacaca （Hydrophasianus chirurgus） and lesser sand plover （ Charadrius mongolus） were new bird records in wetlands of Dianehi Lake. Of the total recorded shorebirds, 731 individuals belonging to 18 species were mainly found in Fubao Bay wetlands, which were made by human as parts of the Dianchi Lake Restoration Project. It was believed that the special preferred habitats for shorebirds in Fubao Bay wetlands consisted by large area shallow muddy flats, open water and dense vegetation cover might cause the new distribution of 3 sborebirds species and cluster of numerous shorebirds.
