摘　　要：巢址选择是鸟类繁殖的重要环节,其与鸟类繁殖成功率密切相关.2023—2024年对吉林师范大学校园内灰喜鹊营巢特征进行了研究.灰喜鹊的巢呈深碗形,其深度平均为8.1 cm,内径平均为10.1 cm.内垫巢材包括聚酯纤维丝、破布条、旧棉絮、塑料布条、塑料丝带等许多人造材料.灰喜鹊全部选择阔叶树进行营巢,其中83%的巢位于柳树上.经主成分分析发现,巢处分枝数、巢距地高和筑巢树高是影响灰喜鹊巢址选择的主要环境因子,它们的主成分分析贡献率合计为85.88%.灰喜鹊已经成为与人伴居的城市鸟类,其筑巢等行为与当前生存环境密切相关.The selection of nest sites for birds is an important link in bird reproduction,which is closely related to the success rate of bird reproduction.A study was conducted on the nesting characteristics of azure-winged magpie on the campus of Jilin Normal University from 2023 to 2024.The nest of the azure-winged magpie is deep bowl shaped,with an average depth of 8.1 cm and an average inner diameter of 10.1 cm.The inner lining material includes many artificial materials such as polyester fiber,rag strips,old cotton wool,plastic cloth strips,plastic ribbons,etc.All azure-winged magpies choose broad-leaved trees for nesting,with 83%of their nests located on willow trees.Through principal component analysis,it is found that the number of branches in the nest,the height of the nest from the ground,and the height of the nesting tree are the main environmental factors affecting the selection of nest sites for azure-winged magpie,with a total contribution rate of 85.88%in principal component analysis.azure-winged magpies have become urban birds that live with humans,and their nesting behavior is closely related to the current living environment.
