【摘要】 利用无线电追踪技术测定了北京小龙门林场黄眉姬鹟(Ficedula narcissina elisae)和白眉姬鹟(F.zanthopygia)繁殖期的活动区,活动区面积为2 000~5 000 m2,2种姬鹟主要在距巢60~70 m的山沟底部和山坡下部活动,繁殖前期的个体的活动区面积大于孵卵和育雏期的个体.黄眉姬鹟活动区内的林冠盖度、高大乔木的数量和枯树树桩的数量显著大于白眉姬鹟的活动区(P<0.05).黄眉姬鹟活动区内的优势树种是棘皮桦(Betula dahurica),白眉姬鹟活动区内的优势树种是核桃楸(Juglans mandshurica).更多还原

【Abstract】 The home ranges of Narcissus Flycatcher（Ficedula narcissina elisae） and Yellow-rumped Flycatcher（F.zanthopygia） are measured by radiotelemetry method in subalpine forest near Beijing,China.The home range is calculated by 100% Minimum Convex Polygon,and area varies from 2（）000（）m² to 5（）000（）m².The majority of positions of flycatchers lies in the bottom of valleys and the underside of mountains.It is fairly rare for both of Flycatcher species to leave their nests more than 70（）m.Individuals of the species in pair-banding and nest-detecting periods have larger home ranges than those in incubation and rearing periods.The levels of canopy coverage in the home ranges of Narcissus Flycatchers are significantly higher than that of Yellow-rumped Flycatchers.And there are also more tall trees and stumps in home ranges of Narcissus Flycatchers than in that of Yellow-rumped Flycatchers.The dominant tree species in the home ranges of Narcissus Flycatchers is Dahurian Birch（Betula dahurica）,whereas Manchurian Walnut（Juglans mandshurica） is the dominant tree species in the home ranges of Yellow-rumped Flycatchers’.更多还原
