Statistic analyses of the proportions of the three major bones of the hindlimb（femur, tibiotarsus and tarsometatarsus）from 137 skeletons belonging to 59 families of 18 orders of living birds with different perching habits show that they can be used as a good indicator of their living styles.

通过对18目59科137例现生不同栖息习性鸟类的后肢3块骨骼长度比例的观察和特征分析，推断出鸟类的栖息习性与后肢3块骨骼中各骨骼长度所占总长度的比例存在密切的关系。
