摘　　要：2013年3—6月、2014年3—6月,在广西弄岗地区对长尾缝叶莺(Orthotomus sutorius)和栗头缝叶莺(O.cuculatus)的巢址特征进行调查,以比较两者巢址选择的差异。野外共发现64个长尾缝叶莺和47个栗头缝叶莺的巢,其中长尾缝叶莺有60巢(93.7%)位于村庄林下,4巢(6.3%)位于山脚阔叶林;栗头缝叶莺有3巢(6.3%)位于村庄林下,44巢(93.6%)位于山脚阔叶林。主成分分析结果表明:影响长尾缝叶莺巢址选择的主要生态因子为筑巢植物的高度、距林缘距离和海拔;影响栗头缝叶莺巢址选择的主要因素为筑巢植物的高度、巢四周的隐蔽度和距山峰的距离。判别分析结果表明,距山峰的距离是区分2种缝叶莺巢址选择的最重要参数。Nest site selection and nest characteristics of Common Tailorbird （ Orthotomus sutori- us） and Mountain Tailorbird （0. cuculatus ） in Nonggang, Guangxi, Southwest China, were compared in the breeding season from March to June 2013-2014. A total of 64 nests of O. stttori- us and 47 nests of O. cuculatus were found. Among them, 60 nests （93.7%） of O. sutorius were located in the forest nearby village, while 44 nests （93.6%） of 0. cuculatus were found in the forest at the mountain foot and far from village. The principal component analysis indicated that the main factors for nest site selection by O. sutorius were height of nesting trees, distance to for- est and altitude, whilst the main factors for 0. cuculatus included height of nesting trees, visibili- ty around nest and distance to mountain. Linear discrimination analysis showed that distance to mountain plays the most important role in nest site selection for the two tailorbird species.
