卧龙血雉繁殖期行为特征分析

Blood Pheasant Behaviour during the Breeding Season in Wolong Nature Reserve,China

1 995年 4～ 6月在四川卧龙自然保护区五一棚地区 ,采用无线电追踪技术结合野外行为观察 ,对血雉繁殖期行为特征进行了研究。结果表明 ,繁殖前期雄鸟在警戒行为的频次及持续时间上均显著地高于雌鸟 (T test,频次 ,t=-4 73 ,P <0 0 1 ;时间 ,t=-2 80 ,P <0 0 5 ) ;孵卵期 ,雄鸟在警戒行为的总持续时间上显著地高于雌鸟 (T test,t=-4 75 ,P <0 0 1 ) ,雌鸟在取食行为的总持续时间上显著地高于雄鸟 (T test,t=3 41 ,P <0 0 5 ) ;对雌雄个体行为同时进行观察的结果表明 ,雌鸟维持行为的时间与雄鸟警戒行为的时间显著正相关 (Y =49 68+0 2 693X ,r=0 71 79,P =0 0 0 2 6)。繁殖前期和孵卵期雄鸟的警戒行为可以提高雌鸟用于取食、理羽、沙浴的时间 。

From April to June 1995,the behavioural characteristics of Blood Pheasant pairs( Ithaginis cruentus) were studied in the Wuyipeng area of Wolong Nature Reserve in Sichuan Province by radiotelemetry and field observations.Focal sampling and tape recording methods were used to observe Blood Pheasant behaviour and analyse its total duration and frequency.The results show that males were more vigilant than females during the pre incubation period( T test,frequency, t =-4 73, P <0 01;total duration, t =-2 80, P <0 05).During the incubation period males were more vigilant than females( T test, t =-4 75, P <0 01) and females spent more time feeding than males ( T test, t =3 41, P <0 05).Simultaneous observation showed that females′ maintenance beha\|viour was related to males' vigilance ( Y =49 68+0 2693 X,r =0 7179, P =0 0026).Increased male vigilance during pre incubation and incubation period may allow females to reduce theirs,thereby increasing the proportion of time they spend feeding,preening and dusting.
