白马鸡配对期两性行为的比较

COMPARISON OF MALE AND FEMALE BEHAVIOR OF WHITE EARED-PHEASANT(Crossoptilon crossoptilon)

2003年4月和2004年4月在四川省稻城县著杰寺采用瞬时扫描取样法对野生白马鸡(Crossoptiloncrossoptilon)配偶行为进行了研究.结果表明,白马鸡配偶中雌、雄个体全天伴随活动,无特殊情况不会分离.在不受其他个体干扰的情况下,配偶移动时雌性多在前并控制移动方向.雌、雄鸟间距离平均为(1.75±0.03)m,在雄性驱逐其他个体时间距最大.在全天行为记录中,雄性警戒的时间最多,之后依次为取食、移动、驱逐、站立、休息和其他行为.雌性在一天中行为时间分配依次为取食、移动、休息、站立、警戒和其他行为.驱逐行为完全由雄性承担.两性共有行为中雄性用于警戒的时间显著高于雌性(P<0.05),用于取食、休息的时间显著低于雌性(P<0.05),用于移动和站立的时间与雌性差异不显著(P>0.05).

In April 2003 and 2004, the behavioral characteristics of breeding pairs of White Eared-pheasant （Crossoptilon crossoptilon） were studied by the methods of scan sampling in Zhujie monastery in Daocheng county Sichuan province. Without serious disturbance, thd male and its mate accompanied each other in whole daytime. Mean distance between thd male and female was （1.75±0.03） m. The distance was the largest when thd male was driving other individuals. When pairs were moved, the female tended to be in the front and controlled the direction. In whole day time observations, the male spent most of the time in guarding, followed by feeding, moving, driving, standing, resting and other behavior; The female spent most of the time in feeding, moving, resting, standing, guarding, and other behavior. Driving was only found on the male. The male spend more time in guarding and less in feeding and resting than its mate. The time spent on moving and standing did not show significant differences between the male and female.
