【Abstract】 The morphological construction of digestive system of Milvus migrans has been observed primarily by naked eyes and dissecting microscope.The results indicate that the tip of the tongue is obtuse,while the root of the tongue is bifurcate,and there are many bomblike papillas pointing towards hind section on the fork of the mucous membrane.The esophagus is wide and flat ,and there is no crop that obviously can be seen. On the inside of muscaular stomach there is no obvious construction that is similar to cutin membrane.The length of intestine is 2.3 times as long as that of the whole body. The small intestine is relatively developed,which length is 1275mm,and it is 93.6% of the length of intestine.The cecum is degenerate.The pancreas is short and thick.At last,the digestive system of Milvus migrans is compared with that of Spilornis cheela and Buteo lagopus .更多还原
