Two Field Techniques for Estimating Relative Abundance of Galliformes

Galliformes are often difficult to count adequately in their natural habitats due to low detectability of them. In the present study, we confirm availability of feather-count and feces-count as two useful field techniques to estimate the relative abundance of eared-pheasants (Crossoptilon spp. ). The former is suitable to forest environments during the post-incubation period, whereas the latter is best in areas with dry climate conditions during the fall-winter season. With the advantages of reduced survey effort and high repeatability, the two techniques are potentially applicable to other Galliform species in habitat selection studies and long-term population monitoring.     

夏季褐马鸡(Crossoptilon mantchuricum)取食、梳羽等行为的初步观察

1 999年 6月对笼养条件下褐马鸡的取食、梳羽等行为进行了观察 .运用生物学统计方法 ,分析了 1 2d的数据 .结果发现 :笼养褐马鸡的取食和走动具有两个高峰期 ,分别在早 6 :0 0～ 7:0 0和晚 1 7:0 0～ 1 8:0 0 .梳羽和休息在白天呈现一个高峰期 ,为 9:0 0～ 1 4:0 0 .取食和走动相伴随 ,休息和梳羽相一致 .走动是影响取食的原因之一 ,休息成为影响梳羽的因素之一 .
