摘　　要：本文从生态类群角度,对游禽(绿头鸭、秋沙鸭、鹊鸭、斑嘴鸭)、鸣禽(红尾伯劳、白头鹀、白眉鹀)、猛禽(雕鸮、金雕)和涉禽(苍鹭)这4种生态类群中10种鸟的消化系统形态结构进行了比较分析。研究获得各项基础数据,通过比较表明,4种生态类群10种鸟类消化系统形态多处存在明显差异。对于不同生态类群的鸟类来说,食性、食物的质量及活动特点等是影响消化系统形态的重要因素。The digestive systems from 10 species of birds in 4 kinds of ecological groups were compared mophologically. The four groups were swimming birds （Anas platyrhynchos , Mergus merganser, Bucephala clangula, Anas poecilorhyncha ） , song birds （Lanins cristatus, Emberiza leucicephala, Emberiza laucocephala ） , birds of prey （Bubo bubo, Aguila chrysaetos） , and wading birds （Ardea einerea）, There are a number of significant differences in morphology between the digestive systems of these birds. Feeding habits, the quality of food and activities, and other characteristics are the important factors affecting the morphology of the digestive system for birds of different ecological groups.
