校园内人工巢箱招引鸟类初报

2007年12月至2008年8月，在昆明西南林学院校园内开展人工巢箱招引鸟类工作，希望籍此了解某些园林中的次级洞巢乌选择巢箱的条件。校园内挂2种类型的巢箱共72个，有树麻雀和鹊鸲2种鸟利用巢箱29个，利用率达40．28％。分析显示，巢箱利用与否和巢口朝向、巢高、巢箱所在分枝等级及隐蔽度没有明显关系，而巢箱类型是影响2种乌成功利用的最主要因子。

Preliminary Report on Bird Attracttion by Artificial Nest-boxes on SWFU Campus

72 nest-boxes of two types were hung on the campus trees of Southwest Forestry University from December of 2007 to August of 2008 to explore the way how the secondary hole nesting birds which are commonly observed in landscaping green spaces choose the nest-boxes, The observation indicated that Eurasian Tree Sparrow （ Passer montanus） and Oriental Magpie Robin （ Copsychus saularis） occupied 29 nest-boxes of the 72, accounting for 40.28% of the total. The analyses showed that the occupation rate of the nest-boxes was not significantly related to the opening direction, height, hidden extent and the branch position where the nest-boxes to be hung. Whereas the nest-box type was the most important factor to influence upon the occupation rate of these two bird species.
