【摘要】 野外观察结合无线电遥测研究表明 ,河南董寨鸟类保护区白冠长尾雉在非繁殖期倾向于集群活动。雄性集群、雌性集群和两性混合集群是其常见的 3种集群方式 ,但以单性集群为主 ,并且性别隔离现象明显 .繁殖期观察到亚成体仍集群活动 ,但发现成体也有集群行为 ,推测其原因可能是繁殖的需要 .观察期内平均群体大小为 (3 87± 2 2 4 )只 ,而雄群、雌群和混合群平均群体大小依次为 (2 54± 0 31) ,(3 81± 0 4 0 )和 (6 4 2± 1 2 5)只 ,三者之间均存在极显著差异 (p <0 0 1) .群体活动对研究区内 7种生境类型的利用有明显选择性 (χ2 =93 545,d =6 ,p =0 ) ,其中混交林、幼林和茶灌是集群活动利用的主要生境 .集群活动对坡位的利用存在时空变化 .冬季和繁殖前期对坡位的利用相似 (z =- 0 36 ,p =0 79) ,而与繁殖期和繁殖后期存在明显差异 (χ2 =0 0 2 8,d=3,p =0 0 2 8) ,表现在对坡下位的利用方面 .白冠长尾雉集群个体的组成相对稳定 ,群体内个体间关系多样化 .遥测结果表明 ,雄性集群的形成过程依次是 :独立活动、靠近、尾随、一起活动更多还原

【Abstract】 Reevess pheasant is an endangered bird native only to China. From December 1999 to August 2000, the flocking behavior and activities of reevess pheasant ( Syrmaticus Reevesii) were studied using radio telemetry in Dongzhai Bird Nature Reserve. The study sites lie in the north slope of West Dabie Mountain, which is the core area of reevess pheasant ranges extant in China. The results show that there exist 3 flock patterns in the group of reevess pheasant in non or breeding season, i.e. male group, female group and mix group; but the motivation caused flocking behavior may be distinct between the two seasons. It is likely the stimulus of reproduction, which cause the flocking behavior for breeding season rather than the factors such as food or predation for non breeding season. Males and females can be seen in a mix group, but they are more inclined to flock separately. The average size of all groups observed is (3 87±2 24) birds ( n =101) and those of male group, female group and mix group are (2 54±0 31) ( n =24), (3 81±0 40) ( n =27), (6 42±1 25) ( n =24 ) birds respectively ( χ 2 =36 957, d =2, p =0). Yong growth of forest, Tea farmland and Cropland are the three of seven habitat types, which are used high frequently by groups in all time. In winter and pre reproduction period, it is easier to witness flocking behavior in the under part of mountain than in the up part ( z =-0 36, p =0 79). However, the result is distinctive from the period of reproduction ( z =-2 426, p =0 015). The relationship between the members of group maybe diversity but 3 of them known so far are stable. The research suggests that the process for males flock forming might be: living alone, approaching, tagging and flocking orderly.更多还原
