摘要:

冠斑犀鸟(Anthracoceros albirostris albirostris)属于国家II级重点保护野生动物, 并且是亚洲热带地区重要的种子传播者。冠斑犀鸟在20世纪70年代以前曾广布广西西南部中越边境地区, 但其分布范围持续萎缩, 2000年以后只残存于3个孤立的分布点, 而西大明山林区一直是冠斑犀鸟的主要分布点。为了解此物种在广西的最新分布状况, 我们于2009年在广西西大明山自然保护区首次进行了冠斑犀鸟的同步调查, 同时调查了当地犀鸟可利用的植物资源。结果显示至少有50只冠斑犀鸟在当地栖息, 是广西目前最大的种群, 但数量明显呈下降趋势。本文记录了124种犀鸟可潜在利用的植物, 探讨了广西犀鸟面临的威胁, 并呼吁国家有关部门和科学界加强对中国犀鸟保育研究的关注。

Abstract:

The oriental pied hornbill (Anthracoceros albirostris albirostris) is a State Protected Species and also an important seed dispersal agent in Tropical Asia. Recent studies show that the range of oriental pied hornbill in Guangxi has decreased significantly in the last decades. During the 1970s the species was widespread along the Sino-Vietnamese border but since the 2000s it has been confined to only three isolated areas. Although the population has declined substantially, Xidamingshan still supports the largest hornbill population known in Guangxi. In order to understand the current status of the species in Guangxi, China, we conducted a simultaneous population survey in Xidamingshan Nature Reserve in 2009. At least, fifty birds were recorded during survey and 124 plant species are identified as potential food source of the bird. Human disturbance and hunting are the main threats to the species in Guangxi. Further research and conservation of the species are urgently required.
