- Abstract
From 2007 to 2009, a study on the seasonal changes in the ranging area of blue-eared pheasant (Crossoptilon auritum) and its affecting factors was conducted in the Gahai-zecha National Nature Reserve, Gansu Province, China. The foraging-site samples and random-plot samples were selected by line transects crossing the study area. Fifteen factors related to the changes of vegetation factors, terrain factors, and food factors, etc were measured in each site. The main result of this study indicated there are significant difference on seasonal habitat change in altitude, slope degree, position on slope, cover of tree and grasses between breeding season and non-breeding season. Our results suggested that vegetation features and food resources were the most important habitat factors influencing habitat selection of blue-eared pheasants. High quality vegetation features with adequate camouflaged foraging-sites and fewer human disturbances in the breeding stage is important to ensure the maximum reproduction and survival of birds. However, in the non-breeding stage, due to lack of abundant food, blue-eared pheasants in winter always have larger habitat territories such as different types of forest or a larger range of altitudes to find more food resources.
