The digestive system of the Chinese Grouse (Tetrastes sewerzowi) was observed for the first time in seven adults from the Lianhuashan Natural Reserve in Gansu,China. The gut length was 161 ± 21 cm,with small intestine and cecum consisting of 40. 2% ± 3. 2% and 44. 9% ± 2. 4% of the total length. The crop volume was 42 ± 9 ml. The ratio of cecum to small intestine was higher than that of other grouse species with the similar weight,such as the Hazel Grouse ( T. bonasia) and the White-tailed Ptarmigan ( Lagopus leucurus), possibly due to the adaptation to fibrous diet.
