在贵州草海越冬的斑头雁粪便中共检出３６种植物，其中天然植物２８种，栽培作物８种。禾本科植物是斑头雁主要食物，在其粪便中的平均检出率是６５０％，白花三叶草平均为１６４％，莎草科植物为９７％，农作物仅占５６％，其他的材料为３３％。随着月份的不同，六种主要植物及栽培作物在斑头雁粪便中的变化非常明显（Ｐ＜００００１，ｄｆ１＝４，ｄｆ２＝７０）。
36 species of plants were detected in the feces of Barheaded Geese wintering at Cao Hai, Guizhou Province. 28 of them were natural plants and 8 were cultivated plants.

White Clovers accounted for 164%, Sedge family plants accounted 97%, crops accounted for 56% and the other materials accounted for 33%.
