对8只(4♀,4♂)画眉消化系统的形态学作了初步的观察与研究,画眉的舌成细长三角形,前端有刺毛状结构,雌鸟的刺毛数目多且较细,雄鸟的刺毛则数量少,但是相对较粗大.舌后端有1～2排尖端后指的栉状突.雌雄鸟在舌前端正中央还有一"V"形的凹缺,雌鸟深约1.22 mm,雄鸟深约1.87 mm.食管管径较细,整体宽窄不等,无明显可见的嗉囊.腺胃乳突短而小,分布均匀,肌胃发达,具角质膜.肠道长与体长基本相等,小肠较发达,雌鸟小肠长178.53 mm,占肠道总长87.43%;雄鸟小肠长186.62 mm,占肠道总长89.01%.具有不发达的双侧盲肠,盲肠有未倒置现象.肝为体内最大的消化腺,分左右两叶,右叶又分一小叶.胰位于十二指肠袢内,细长形,分两小叶.并与同科的蓝翅希鹛、灰胸薮鹛进行了比较.

The morphological construction of the digestive system of 8 individuals (4 females, 4 males) of Garrulax canorus has been observed visually and microscopically. The results indicate that the tongue is a thin triangle, with many setas in the front, and the seta of the female is numerous and thin, while that of the male is fewer and crassituder. On the root of the tongue there are many tuber-like structures pointing backward in one or two lines. The apex of the tongue is furcate, and the furcate depth of the female is 1.22 mm and the male is 1.87 mm. The esophagus is thin, while the width of whole esophagus is different, and there is no crop that can obviously be seen. On the surface of glandular stomach there are short and small papilla, and the muscular stomach is growth with a flat of developed horniness on the inside. The length of the intestine is almost as long as that of the whole body. The small intestine is relatively developed, with a length of 178.53 mm in females accounting for 87.43% of the total length of the intestinal tract, while the male is 186.62 mm and 89.01%. The caecum is degenerate and the rightward caecum of one swatch is not inverted. The liver is the biggest digestive gland in the coelom and separates into two parts, and the right one separates into two parts too. The pancreas is located in the bend of the duodenum and is thin and long, which all divides into two parts. We also compare the digestive system of Garrulax canorus with that of Minla cyanouropter and Liocichla omeiensis.
