| 摘 要： | 本对大鵟消化系统的形态学结构特点作了观察，结果表明，大鵟的喙锋利，食管粗大且收缩性较大，嗉囊较发达，肌胃不太发达，仅具单侧盲肠，相对体长而言肠管较短，但小肠较发达．这些结构都与其肉食性生活相适应．

| Abstract: | The observation on morphological structures of the digestive system of Buteo hemilasius has been carried out by OLYMPUS dissection microscope in this paper.It conveys that this species of bird has sharp beak which can lacerate the food.It also shows that the small intestine is well developed but cecum is degenerate. Buteo hemilasius has one side cecum only. According to the comparison between Buteo hemilasius and some other birds,the carnivorous birds have well developed small intestine and undeveloped cecum, while the herbivorous birds have mild developed small intestine and well developed cecun. |
