崇明东滩鸻鹬类迁徙路线的环志分析

Migration Routes of Shorebirds across Chongming Dongtan Based on Recovery of Bird-banding

崇明东滩为东亚-澳大利西亚鸻鹬类迁徙路线上的重要迁徙停歇地。本文通过分析崇明东滩回收的异地环志鸻鹬类记录及异地回收的崇明东滩环志的鸻鹬类记录,研究崇明东滩鸻鹬类的迁徙路线。1979-2008年间,崇明东滩共回收到来自澳大利亚西北部、澳大利亚维多利亚、美国阿拉斯加及新西兰北岛等17个国家与地区环志的鸻鹬类265只,包括大滨鹬（Calidris tenuirostris）、斑尾塍鹬（Limosa lapponica）、红腹滨鹬（C.canutus）等16种鸟类,其中春季北迁期间的记录占总数的93%;2003-2008年间,澳大利亚西北部、新西兰南岛、中国大陆及新西兰北岛等10个国家与地区回收到崇明东滩环志的大滨鹬、斑尾塍鹬、红腹滨鹬等12种鸟类,共计164只。在所有与崇明东滩鸻鹬类存在迁徙连接的20个国家和地区中,澳大利亚西北部的回收记录占全部回收记录的55%。根据斑尾塍鹬和红腹滨鹬不同亚种的越冬地分布,崇明东滩回收的斑尾塍鹬有L.l.menzbieri与L.l.baueri两个亚种,红腹滨鹬有C.a.piersmai和C.a.rogersi两个亚种。

Chongming Dongtan is an important stopover site for shorebirds along the East Asian-Australasian Flyway. Based on the recoveries of shorebird banding and leg-flagging records, we analyzed the migration routes of shorebirds across Chongming Dongtan. A total of 265 shorebirds of 16 species banded in 17 countries and regions were recaptured at Chongming Dongtan,including Great Knot （Calidris tenuirostris ）, Bar-tailed Godwit （Limosa lapponica ） and Red Knot （C. canutus ）. 93 % of them were recaptured during spring migration. In addition, 164 shorebirds of 12 species banded at Chongming Dongtan were recaptured at ten countries and regions, including Northwest Australia, where 55% of the total recoveries occur. Two subspecies of Bar-tailed Godwit （L. l. menzb/er/ and L. l. baueri） and Red Knot （ C. c. piersmai and C. c. rogersi） that reported wintering in northwest of Australia and in east of Australia and New Zealand were captured in the study area.Those birds are stopover at Chongming Dongtan during migration.
