摘　　要：对10只(6♀4♂)红嘴相思鸟消化系统的形态结构进行了较为系统的解剖与观察,并对各器官进行了测量。结果表明,红嘴相思鸟舌前端有刺毛状结构,后端有一排尖端后指的栉状突;咽有不规则乳突,食管较细,无明显可见的嗉囊;腺胃内壁粘膜上均匀分布小而多的圆形乳突,肌胃发达,内有黄色革质层;肠道总长约为体长的0.94倍。The morphological structure of the digestive system of Leiothrix lutea was investigated. 10 （6 ♀4♂） Leiothrix lutea were observed with the naked eye and OLYMPUS dissection microscope. The results showed that there are many setae in the front of the tongue, and tuber-like structures on the root of the tongue pointing backside. Many irregular papillae are distributed on the surface of the pharynx. The esophagus is thin, and there is no craw that could be seen obviously. There are short and small papilla on the surface of the glandular stomach. The muscular stomach is well developed and covered with a yellow horniness inside. The length of the intestine is 0.94 times as long as the whole body.
