哈尔滨市区灰喜鹊巢址选择研究

2010年6月至9月在哈尔滨市园林科学研究所实验基地采用样方法对灰喜鹊的巢址选择特征进行研究,并且利用主成分分析法对灰喜鹊巢址样方生境因子进行检验.结果表明,灰喜鹊主要选择针叶树筑巢;在同一生境中巢间距变化小,呈均匀分布;灰喜鹊巢址选择的主要因子包括营巢树高、距最近巢距离、样方内树均高、巢树胸径、距干扰源距离、距最近树距离.这说明灰喜鹊在巢址选择过程中选择巢树和其周围的小生境.

Nest-site Selection of Azure-winged Magpie in Harbin

Selection of nest-site of azure-winged magpie in experimental bases of garden science institution in Harbin was surveyed from June to September in 2010 by quadrat sampling method,and factor habitats of nest quadrate were examined by factor analysis method.The results indicated that coniferous forests were mainly selected for nest construction;little variation and homogeneous distribution were presented in distance of the nests in the same habitat;factors including tree height of nest,distance of the nearest nest,the average altitude of arbor in quadrat,the diameter of nest tree,distance to disturbance,distance to the nearest tree were measured and analyzed.This indicated nest trees and small surrounding habitats were chosen by azure-winged magpie in selection of nest habitats.
