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 blue-eared pheasant (Crossoptilon auritum) belongs to the family Phasianidae, Order Galliformes.
Therefore, the aims of this study were to measure habitat characteristics in breeding and non-breeding seasons of blue-eared pheasant, and to identify what key variables influence habitat selection.
In study area, there are some farmlands on the foot of a mountain which can provide the deciduous grain as potential food source for blue-eared pheasant (Liu and Ma, 1997).
The variables comparisons between summer habitat and control site of the blue-eared pheasant during breeding stage.
Stepwise discriminate analysis indicated that the Blue-eared Pheasant selected to nest in habitats with higher vegetation cover at heights of 1 m and 2 m, lighter disturbance and higher slope position.
Key words: Blue-eared pheasant, Crossoptilon auritum, Gahai-zecha Nature Reserve, nest-site characteristics, stepwise discriminate analysis.
The Blue-eared Pheasant (Crossoptilon auritum) is endemic to China and is mainly found in the east and northeast Qinghai Province, northwest and south Gansu Province, northwest Sichuan Province, and west Ningxia Autonomous Region (Lu et al.
Nests characteristics of Blue-eared pheasant (n=12).
