【摘要】 本文报道了卧龙自然保护区冬季血雉的活动区、夜栖行为及行为特征.血雉冬季营集群生活.越冬早期活动区较为固定,至后期受雪被的影响而大范围游荡觅食,活动区面积增大.血雉喜选择灌木夜栖.应用主成分分析法对冬季33株夜栖树进行了分析,结果表明,栖树(栖位高度、栖树胸径)、地形(海拔高度和坡向)是影响冬季夜栖树选择的主要因素.冬季雌雄性别间的行为无显著性差异(T-test,P>0.05),取食行为是雌雄鸟此期的主要活动.更多还原

【Abstract】 In this paper we reported the winter home range, roosting behaviour and behavioural characteristics of Blood Pheasant (Ithaginis cruentus) at Wolong Nature Reserve. In winter, Blood Pheasant lived in flock. The home range of wintering flock was stable in early winter. The flock moved more frequently in February than in January. Blood Pheasant preferred to roost in shrub. Principal content analysis showed that the roosting tree factor (roosting heights and roosting trees DBH) and the terrain factor (altitude and aspect) were the main factors affecting selection of roosting trees in winter. Focal sampling was used to observe the behaviour of Blood Pheasant. No significant differences were detected between sexes in winter (T - test, P >0.05). Feeding was the main behaviour in winter.更多还原
