Abstract: 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.
