选择10种隼形目鸟类尾羽，利用扫描电镜观察其绒羽显微结构，同时测量节直径和节间长度。结果表明绒羽主要由节状羽小枝构成，各种类节的形状、节直径和节间距存在差异。单因素方差分析表明除苍鹰和松雀鹰外，其他2个物种间至少有1个参数差异显著或极显著，说明把这2个参数综合起来考虑可为物种鉴定提供帮助。
選擇10種隼形目鳥類尾羽，利用掃描電鏡觀察其絨羽顯微結構，同時測量節直徑和節間長度。結果錶明絨羽主要由節狀羽小枝構成，各種類節的形狀、節直徑和節間距存在差異。單因素方差分析錶明除蒼鷹和鬆雀鷹外，其他2箇物種間至少有1箇參數差異顯著或極顯著，說明把這2箇參數綜閤起來攷慮可為物種鑒定提供幫助。

The downy feathers of 10 species of Falconiformes were selected and observed under scanning electronic microscope. The diameter of nodular and distance between 2 nodular were measured. The results showed that the downy feathers were mainly composed of nodular barbules. There were some differences in the shapes, diameters of nodular and distance between 2 nodular among the species. One-way ANOVA analysis showed that there were significant difference on at least one parame-ter in the two analyzed parameters between two species besides Accipiter gentilis and Accipiter virgatus, indicating that the 2 parameters could be used to identifying species.
