Abstract:From November 2006 to January 2007, the roost-sites of brown-eared pheasant Crossoptilon mantchuricum was investigated in the Beisishan Forest of Huanglong Mountains, Shaanxi Province. A total of 34 roost-sites and 34 random plots were measured. The resource selection functions of the roost sites is a log-linear model: logit(p)=11.537+2.245×slope degree+3.452×cover of trees+2.001×number of trees2.903×the distance to the nearest village. From this model, the roost-site selection probability can be estimated as P=e logit(p)/(1+ e logit(p)), the overall classification model developed from those four variables was successful to distinguish the roost-sites from random ones at probability of 93.8%. The model also indicated that the roost-sites selection of brown-eared pheasant was positively related to the slope degree, the cover of trees and number of trees, negatively related to the distance to the nearest village.
