贵州省的鹤类

Cranes in Guizhou Province

该文综述了贵州省现有的3种鹤类,即灰鹤(Grus grus)、黑颈鹤(Grus nigricollis)和白头鹤(Grus monacha)的分布、迁徙和研究现状。贵州省鹤类目前仅分布于西部的草海,根据记载和标本资料,黑颈鹤还曾见于普安县和习水县,灰鹤也在贵阳市红枫湖有过记录。对黑颈鹤进行的环志研究,查清了贵州的黑颈鹤种群是在草海和四川西部若尔盖沼泽之间迁徙。以在贵州回收的红嘴鸥(Larus ridibundus)环志和环志放飞的绿翅鸭(Anas crecca)都与灰鹤有共同的越冬区为依据,提出分布于贵州省的灰鹤有来自俄罗斯西伯利亚的可能性。

There are three species of cranes in Guizhou Province–Common(Grus grus),Black-necked(Grus nigricollis)and Hooded Crane(Grus monacha).Currently cranes are found only at Caohai in western Guizhou Province.Historically,Black-necked Cranes were recorded in Puan County in the early 1900s,and an injured bird was found in Xishui County in 2008;a small number of Common Cranes were recorded in Hongfeng Lake near Guiyang City in 1970s.Black-necked Cranes wintering in Guizhou Province migrate to Ruoergai of Sichuan Province to breed.According to one return of banded Black-headed Gulls(Larus ridibundus)and one of the Green-winged Teal(Anas crecca),these birds share the same wintering area in Guizhou with Common Cranes.One Black-headed Gull and one Green-winged Teal banded in Guizhou were recovered in Siberia(Russia),which allows us to suggest that Eurasian Cranes wintering in Guizhou may come from Siberia.
