长江大学西校区灰喜鹊巢址选择

Nest-Site Selection of Cyanopica cyana in West Campus of Yangtze University

摘要: 2021年3月至2021年5月对长江大学西校区的灰喜鹊巢址选择进行了调查研究，共调查了30个巢址样方的巢树参数和环境因子。结果表明，灰喜鹊筑巢树种主要为路边高大的针叶树，尤其是池杉(Taxodium ascendens)和水杉(Metasequoia glyptostroboides)，两种树共占86.7%。营巢树高、胸径，巢位高度，支撑巢枝数，巢距树顶端高度和5 m内树株数是影响灰喜鹊巢址选择的主要影响因子。研究结果对校园建设与绿化及鸟类保护具有一定指导作用。

Abstract: From March 2021 to May 2021, the nest-site selection of Cyanopica cyana in the west campus of Yangtze University was investigated, and the nest tree parameters and environmental factors of 30 nest sites were investigated. The results showed that the major nesting species of the magpies were tall conifers, especially Taxodium ascendens and Metasequoia glyptostroboides, which accounted for 86.7% of the total. Nest height, DBH, nest height, number of supporting branches, nest height from the top of the tree and the number of trees within 5 m were the main factors affecting the selection of nest site. The results of this study have a certain guiding effect on campus construction and greening and bird protection.
