高黎贡山白尾梢虹雉生境利用的初步观察

PRELIMINARY OBSERVATION ON Lophophorus scalateri IN MOUNTAIN GAOLIGONGSHAN

１９９７年４～６月在高黎贡山大塘用鸣声监听和样带、样方法对白尾梢虹雉（Ｌｏｐｈｏｐｈｏｒｕｓｓｃａｌａｔｅｒｉ）的生境利用情况做了初步观察。此间白尾梢虹雉主要活动在海拔３３００～３６００ｍ的箭竹林内，鸣叫集中在１１：００～１７：００，取食贝母、多星韭、牛尾独活、高山羌活、紫花百合。

With the methods of call listening,and counting feces in fixed width transects,and food plants in fixed size quadrats,we tried to collect data on call patterns,range,and diet in Lophophorus scalateri at Mt.Gaoligongshan at west Yunnan in a period from April to June,or its beeding season.The species is endemic to the Eastern Himalayas,poorly known,and highly threatened.The elevation belt of 3400-3600,where the cover was dominated by the bamboo, Fargesiu orbiculata ,(sometimes mixed with few Rhododendron sinogande ) with a few patches of grass lands set in,was freguently used by the pheasant in the seacon according to its calls produced by males.Only one male was found in each valley branch.A female appeared with fledglings in 23 May.The peak period of calls was between 11:00-17:00h.The bird fed mainly on Frotillaria cirrhossa,Allium wallichii,Aralia apioides,Notopteryum forrestii,Lilium sou liei ,and Climtonia udensis etc ,both the parts above and under the ground.This observation is the first step for a proposed long term project of ecological monitoring in the reserve known as one of the richest area in biodiversity in China.
