| Abstract: | For enriching biological material of Buteo hemilasius,the systematical observation on morphological structures of digestive system of Buteo hemilasius in winter was carried out.Results are as follows: the longitudial plica of Buteo hemilasius oesophagus is well developed and crop is obvious.Its muscular stomach wall is thinner than its gland stomach wall,and its muscle and the inter keratinized membrane is not so developed.The bird has short intestines which is about 1.6 times the length of its body and the small intestines is quite developed,making up 94.3 percent of the total length of its intestines. The appendix is not developed.In all the bird digestive system has the typical characteristics of prey bird. |
