2011年4-7月,在贵州宽阔水自然保护区对矛纹草鹛（Babax lanceolatus）的巢址选择进行了调查.野外共发现矛纹草鹛的巢32个,其中23巢（72%）位于灌丛,8巢（25%）位于茶地,1巢（3%）位于农耕地.对其中17巢的主成分分析表明,影响矛纹草鹛巢址选择的主要因素包括灌木因子、草本密度和高度因子、水平隐蔽因子和距林缘距离等.矛纹草鹛倾向于选择灌木、草本都较密集的生境营巢,巢址具有较高的隐蔽性.在5 m×5 m尺度下,巢址中心小样方和巢址内随机样方在各参数上都不存在显著差异,表明矛纹草鹛在巣址尺度内对微生境的选择没有明显的倾向性.

Nest-site choice of Chinese Babax Babax lanceolatus was conducted in Kuankuoshui Nature Reserve, Guizhou, south-western China, from April to July of 2011. Totally 32 nests were found which distributed only in three types of habitats: bush, tea plantation and farmland. Of these nests, 23 (72%) were found in bush, 8 (25%) in tea plantation and l (3%) in farmland. The principal component analysis indicated that the main factors for nest-site choice by Chinese Babax are bush density and height, herb density and height, nest concealment, and the distance to forest. Our resuits showed that Chinese Babax favors the habitat with high density of bush and herb, and nest concealment. Comparisons between nest samples and controls within nest-site scale showed no significant differences in any parameter, which revealed that factors (e.g. habitat type) at a larger scale might play a more important role in the nest-site choice of Chinese Babax.
