扎龙保护区人工林内中华攀雀巢址特征分析

作者2011年9 ～ 10月在黑龙江省扎龙国家级自然保护区对人工林内中华攀雀(Remiz consobrinus)的巢址特征进行了研究.研究期间共发现36巢,选取巢距地面距离、巢距主干距离、巢距挂枝末端距离、巢树胸径等9个巢址因子进行主成分分析.结果表明,巢下生境、巢距地面距离和巢距主干距离以及巢距挂枝末端距离在中华攀雀巢址选择中起主要作用；巢树胸径、巢向和巢挂枝年龄次之.中华攀雀巢距地面(5.59±1.44)m,距主干距离为(1.81±0.50)m,距挂枝末段距离为(0.10±0.04)m,巢树胸径(0.29±0.08)m.巢距地面高度(P =0.002 3)和巢距明水面距离(P =0.003 7)在芦苇沼泽与林地草甸2种生境类型之间差异显著,巢树胸径在林地草甸与房屋农田2种生境类型之间差异显著(P=0.003 4),不同生境类型之间巢距主干距离、巢距挂枝末端距离和巢挂枝年龄无显著差异.

The Nest-site Characteristics of Chinese Penduline Tit in Planted Forest of Zhalong Nature Reserve

Thirty six nests of Chinese Penduline Tits(Remiz consobrinus)located in the planted forest were measured in Zhalong Nature Reserve from September to October 2011. Nine nest-site variables, including nest height, distance to the trunk, distance to the branch end, and diameter at breast height (DBH) were measured proceeded by principal component analysis. The nest height (5.59±1.44 m), distance to the trunk (1.81±0.50 m), to the branch end (0.10±0.04 m) were the most important factor for bird to select their nest. DBH (0.29±0.08 m), nest direction and age of nesting branch were also important factors. Among all the variables, distance to ground (P=0.002 3)and distance to water surface (P=0.003 7)were significantly different between nest located in the reed swamp and in the woodland meadow. The difference between DBH (P=0.003 4) of nest trees in woodland meadow and in farmland were significantly; Distance to the trunk and to the branch end, the age of nesting branch were not significant difference between different habitat.
