Key words: Blue eared pheasant, golden pheasant, lady Amherst pheasant, brown eared pheasant.
From an evolutionary perspective, this strategy of habitat selection of the breeding blue- eared pheasant may be a behavioral and ecological adaptation to avoid predators and maximize their fitness, and an optimal ecological tactic to obtain a high survival rate of their population and maintain a stable population size (Sun, 2002).
Diurnal Behavior of blue- eared pheasant in winter in Zecha, Gansu.
The four species of eared pheasants (Crossoptilon spp.
blue- eared pheasants preferred these forests with higher tree and grasses, higher position on slope, higher species richness, and steeper slope.
The present study also revealed that breeding blue- eared pheasants preferred mid-high and high positions on slopes with more species richness and higher cover of grasses (Table I) because in those areas, more types of plant and higher cover of grasses can provide not only the seeds and roots of grasses for their foraging but also a good place for different kinds of insects, which are the major food resources of their fledglings.
