西藏东南部原始森林夏-秋季节鸡类的栖息地利用(英文)

Summer-autumn habitat use by Galliformes in a primary forest,southeastern Tibet

本文报道了1995年夏-秋季节西藏东南部原始森林鸡类栖息地的利用方式。记录有7个物种,这些物种大多喜欢在阳坡环境,而回避相对潮湿的阴坡环境。在这一鸡类群落中,白马鸡(Crossoptilon crossoptilon)与藏马鸡(C. harmani)的杂交类型在数量上是最丰富的,其次是血雉(Ithaginis cruentus)和斑尾榛鸡(Bonasa sewerzowi)。随后于2001年的调查表明,由于地处偏僻,这些鸡类依然没有遭受人类狩猎和栖息地干扰的影响。

Habitat use by Galliformes in an ornithologically unexplored region,a forest area in southeastern Tibet,was investigated during the summer and autumn periods of 1995.A total of seven species were recorded,most of which preferred habitats on south-facing slopes and avoided those on north-facing slopes where conditions were relatively humid.A hybrid population of White (Crossoptilon crossoptilon) versus Tibetan Eared-pheasants (C.harmani) was predominant among the Galliforme community,followed by Blood Pheasants (Ithaginis cruentus) and Chinese Grouse (Bonasa sewerzowi).A further investigation in 2001 showed that on account of little human activity in the distant primary forests,the birds suffered less of a threat from hunting and habitat disturbance.
