摘　　要：本文对国家II级重点保护野生动物白冠长尾雉消化系统的形态学作了观察与研究 .结果表明 ,白冠长尾雉的小肠相对较长 ,盲肠发达 .文中还就白冠长尾雉的消化系统与部分鸡形目鸟类及猛禽进行了比较 .This paper gives an morphological observation on the digestive system of White-crowned Long-tailed Pheasant by naked eyes and OLYMPUS dissection telescope. It indicates: ① There are dispersal comb-like papilla around larynx and cleft palate and there are 3 rows of them on the roof of buccal cavity and 2 raws on the floor of buccal cavity. The ends of these papilla toward behind the buccal cavity, by which the bird can prevent food falling and escaping; ② The intestine is relatively developed, like some other birds in Phasianidae, and the rectum is average developed; ③ The ratio of liver weight/body weight is positively correlated to the degree of earth-life, namely,if one bird is more earth-lived, the ratio is smaller.
