摘要
2009年和2010年春季,在云南楚雄紫溪山自然保护区对红头长尾山雀的巢址选择进行调查,记述其巢和卵的特征。共记录到34个巢,其中营巢于昆明小檗灌丛中24个,在柳杉小树中营巢8个。对巢址的海拔、坡度等15项数字型参数的主成分分析结果表明:影响红头长尾山雀巢址选择的主要因素依次为:隐蔽因子、地形因子、安全因子、食物因子和营巢树因子;研究地红头长尾山雀巢开口方向多为偏东方向,占76.0%。
Nests, eggs and nest site choice of the black-throated tit Aegithalos concinnus in Zixi Mountain Na- ture Reserve, Yunnan Province were surveyed from 2009 to 2010 in the spring breeding season and all the relevant features were recorded. Among the 34 nests totally found, 24 were nested in the brushes of Berberis kunmingensis tree species, 8 were nested in Cryptomeriafortunei tree branches. The Principal Compositional Analysis （PCA） on elevation, gradient and other 13 factors related to nesting locality of the black-throated tit indicated that the princi- pal factors affecting the nest site choice of the bird were ordered as the hiding factor 〉 relief 〉 safety 〉 food 〉 nest tree species. The study also showed that 76.0% of the nests were open to the eastern direction.
