白颈长尾雉的夜宿地选择研究

Studies on the selection of roosting sites of Elliot's Pheasant

1995年 3至 6月 ,采用无线电遥测和样方等技术 ,对浙江省开化县水坞山区白颈长尾雉的夜宿地选择进行研究 .研究结果显示 ,白颈长尾雉在针叶林内分散夜宿 ,多选择在陡坡、高乔木层盖度较大和地面较空旷地带作为其夜宿地 .夜宿树一般为夜宿地内胸径较大、相对高大和树冠盖度较高的树木 .影响白颈长尾雉夜宿地选择的最重要因素是隐蔽条件 .

The selection of roosting site of Elliot's Pheasant were studied by radio telemetry and quadrat sampling in Shuiwu, Kaihua county of Zhejiang Province from March through June in 1995. The results show that Elliot's Pheasants roost in coniferous forest separately. Most of them choose the patches with steep slope, higher tree cover or open ground as their roosting sites. Roosting trees are usually higher trees with large canopy in the sites. Good shelter is the most important factor in choosing roosting site whatever the site is on a tree or on the ground.
