于2008和2009年4-8月，在吉林省左家自然保护区和土门岭地区对黑枕黄鹂(Orioluschinensis)的巢树和巢址特征进行了研究.运用逐步判别分析的方法对25处巢址和30个对照样方的生态因子进行分析，通过对 Wilk’sλ值的检测确定各因子对判别模型的贡献率，根据生态因子的重要性和贡献率大小确定影响黑枕黄鹂选择的主要生态因素.在黑枕黄鹂选择的巢树中，蒙古栎(Quercus mongolica)所占比率最高，黑枕黄鹂偏爱选择树身高大、树冠体积较大的阔叶树筑巢.巢均位于水平侧枝上，距树主干平均距离为(3.5±0.9)m .逐步判别分析结果表明，树冠盖度、胸径、乔木密度和乔木高度是影响黑枕黄鹂巢址选择的重要生态因素.

Nest tree and nest site of Black-naped Oriole (Oriolus chinensis)were studied in Zuojia Natural Reserve and Tumenling mountains,from 2008-2009.Twenty-five nest sites and 30 samples were analysed by stepwise DA to find maj or ecological factors affecting nest site selection by this bird.Black-naped Oriole nests were located in 7 tree species.Forty-four percent (N=25)of the nests were located in Mongolian Oaks and only 8% were in Korean Larch (Larix olgensis ).Black-naped Orioles preferred to select big tree with large crown as nest sites.The nests were located on horizontal forks.Distance from nest to tree trunk was averaged at (3.5±0.9)m.Stepwise DA showed that tree height,coverage of tree crown,coverage of shrubs and tree DBH were the major factors for nest site selection by Black-naped Orioles.
