2014—2015 in mid-February,in Siping,Jilin province and its surrounding area pylons,We investigated the habitat of kestrels by using the magpie nests breeding. Within the scope of this investigation the magpies 40 nest,determine the kestrels used 20 nest,has not been used 20 nest,by the test analysis. The results showed that this region kestrels using the magpies nest has the characteristics of nest higher and the road wider than the control nest site. Principal component analysis showed that the nest height,direction,the distance from the highway and distance from forest this four habitat loading absolute value is definitely too high. This also illustrated that these several factors has a great influence on the selection of the kestrels’nest.%2014—2015年2月中旬，在吉林省四平市周边及其附近区域的高压线塔上，对利用喜鹊旧巢繁殖的红隼生境进行调查研究。在这一范围内调查喜鹊巢共40巢，确定被红隼利用20巢，未被利用20巢。通过T检验分析。结果表明该地区红隼利用的喜鹊巢址巢高、公路宽2个特征与对照巢址差异显著。主成分分析表明，巢高、巢向、距公路距离和距林带距离这4个生境因子载荷绝对值明显偏高，说明这几个因子对红隼的巢址选择有较大影响。
