摘要: 为了弄清和监测印度黑颈鹤 (Grus nigricollis) 的现状与分布,作者于2000-2014年开展了长期研究。每年在所有已知的黑颈鹤分布点开展调查,同时探索了新的区域。基于黑颈鹤的历史分布区,包括查谟和克什米尔、锡金等的文献记载和调查,该文对印度黑颈鹤的现状与分布进行了综述,详细列出了黑颈鹤在印度的当前现状与分布。首次对过去15年来印度黑颈鹤种群状况进行了报道:整个研究期间,于2012年在拉达克的繁殖地最多记录到139只黑颈鹤个体,于2006年在印度东北部记录到11个越冬个体。Abstract: In order to understand and monitor the status and distribution of the Black-necked Crane (Grus nigricollis) in India, we carried out systematic long term yearly surveys between 2000 and 2014 at all previously known locations as well as attempted to explore new areas. In this paper, we have summarized the distribution and status of the species in its historic range based on the literature and data collected during surveys in Jammu & Kashmir and at few locations in Northeast India. This paper presents a detailed account of the current status and distribution of the Black-necked Crane in India. The present study is first of its kind which monitored the Black-necked Crane population in India for a period of 15 years. During the entire study period, a maximum of 139 birds were recorded in breeding areas in Ladakh in 2012, and 11 wintering birds were recorded in norteast India in 2006.
