摘要
2015年12月与2016年3月,在南昌市江西师范大学瑶湖校区和宜春靖安县宝峰镇对白腰文鸟(Lonchura striata)的巢址选择进行了调查.主成分分析表明,影响白腰文鸟巢址选择的主要因素包括巢树与食物及水因子、安全因子和巢隐蔽因子.用5 m×5 m样方法对巢址和对照样方进行统计分析表明,巢树高和林冠宽度存在显著差异.这一结果表明,白腰文鸟倾向于选择树较高、林冠较宽的小生境营巢,这与巢需要高的安全性有关.
In December 2015 and March 2016 ,nest-site selection of White-rumped Munia Lonchura striata was investigated in Nanchang City and Yichun City, Jiangxi Province. The principal composition analysis indicated that the main factors affecting the nest-site selection of White-rumped Munia were nest-tree, food abundance, water, nest security and nest concealment. Comparisons between the nest-site and control plots revealed significant differences in- nest-tree height and canopybreadth. This study indicated that the White-rumped Munia preferred higher tree and wide canopyas nest-site, which was related with higher security requirement for nest.
