摘　　要：笔者于2006年3～4月对吉林莫莫格国家级自然保护区的夜鹭的巢区结构进行研究。研究内容包括夜鹭巢的数量、巢间距、巢位高、每棵树上的夜鹭巢数及分布类型等。结果表明夜鹭筑巢主要选择树高20．04m(±1．96m)、树径20．9cm(±3．3cm)且离水源较近的杨树林,巢位置在距地面高度为19．81m(±1．26m),距树顶的距离为2．23m(±1．47m)。夜鹭巢的巢间距6．27m(±3．64m),且50．9％夜鹭选择一棵树上仅筑一个巢。夜鹭巢分布状态服从集群分布。Nest site was studied during structure of the Night Heron, a medium-sized bird and wide distributed in most provinces of China, March and April, 2006 in Monoge National Nature Reserve, Jilin province. Following items in the nest site structure were recorded： height of trees selected for nesting 20.04m±1.96m;diameter of trees at chest 20.9cm± 3.3cm; height of nest from the ground 19.81m±1.26m and 2.23m±1.47cm below the top of trees; distance between two nests 6.27m±3.64m; one nest per tree 50.9%; in poplar forest near water source and nests of clumped distribution.
