摘　　要：对昆明动物园内干香柏树上营巢的野生小白鹭进行研究,测算其最低适宜营巢枝干和实际最低营巢枝干占树高的百分比,并检测两者的差异显著性。结果表明,实际营巢高度与适宜营巢高度占树高百分比存在显著差异,可能因为亲鸟为避免来自地面的干扰,选择离地较高的位置繁育后代。通过分析坠落鸟巢的构成材料,发现其由268根植物枝条构成,其中91%为干香柏,与主要营巢树一致,说明此地可能由于提供丰富的营巢材料而被鹭群选择成为繁殖地。建议公园积极加强野生涉禽的科学管理,降低繁殖区内及周边的干扰。This paper studied the nest of wild Egretta garzetta on Cupressus duclouxiana trees in Kunming Zoo,and calculated the percentage of the suitable lowest nesting branch and the actual lowest nesting branch in the height of the tree,the significant difference of which was tested..The difference statistically significant indicated that higher positions of a tree were preferred possibly because the parental birds avoided disturbances coming from the ground level in order to protect their offspring.A fallen nest was used to analyze nesting materials,which composed of totally 268 twigs,of which 91.4%were C.duclouxiana,consistent with the main nest-trees indicating that availability of nesting materials was probably one of the reasons for the site selection for breeding by the birds.This paper suggested that the park should strengthen the scientific management of wading birds and reduce the interference in and around the breeding area.
