From February to May in 2012, we conducted a study on nest space partitioning in one mixed-species heronry by direct counting and locating nests in homogenous forests of Dali old city, Yunnan province. The results showed that the heronry was comprised of black-crown night heron ( Nycticorax nycticorax), cattle egret ( Bubulcus ibis) and little egret ( Egretta garzetta), with nest number of 195, 132 and 112, respectively. No difference in nest horizontal distribution was discovered, which was different from the natural one. There was a significant vertical nest stratification among the three species ( x 2=114.6679, df=2, P <0.01), and the distance of nests from the tree trunk varied significantly ( x 2=53.5004, df=6, P <0.01). The majority nests of black-crown night herons were clumped, and the niche width of nest horizontal distribution (from east to west), vertical stratification and the distance of nests from the tree trunk were the smallest among the three species, and the value were 0.750, 0.288 and 0.554, respectively. The bigger body size and earlier arriving at the colony made black-crown night heron individuals concentrated in higher and trunk nest sites. No obvious overlap was found in the four studied spatial factors after comparison of niche overlap values among the three species, indicating a fine scale nests spatial segregation. 2015,34(3): 357-363 收稿日期：2014-7-28 DOI：10.3969/j.issn.1000-7083.2015.03.006 分类号：Q959.7;Q958.15 基金项目：水体污染控制与治理重大专项(2013ZX07105005-02-03); 云南省生物多样性保护专项(云南省环保厅); 大理市洱海治理实施效果研究项目(kyrh201014) 作者简介：赵俊松(1991—),男,在读本科生,主要从事鹭科鸟类生态学研究,E-mail：zhaojunsong5@gmail.com *通讯作者：肖文, E-mail：xiaowen.dali@gmail.com; 张淑霞,sx01.zhang@gmail.com 参考文献： 大理白族自治州苍山保护管理局. 2008. 苍山志[M]. 昆明: 云南民族出版社: 35-43. 戈峰. 2010. 现代生态学(第二版)[M]. 北京: 科学出版社: 318-332. 谭飞, 林英华, 张明海. 2013. 福建漳江口繁殖期鹭科鸟类觅食及巢位空间生态位分离[J]. 野生动物, 34(2): 79-83. 王维奎, 周材权, 龙帅, 等. 2008. 四川南充太和鹭类鸟类群落空间生态位和种间关系[J]. 四川动物, 27(2): 178-182. 王文林, 张丽琴, 李长看, 等. 2004. 郑州鹭类的生态习性[J]. 河南科学, 22(6): 792-795. 文祯中, 王庆林, 孙儒泳. 1998. 鹭科鸟类种间关系的研究[J]. 生态学杂志, 17(1): 27-34. 伍烈, 陈小麟,
