Abstract
The purpose of this problem was to gather information on food habits of migratory water fowl using Cheyenne Bottoms Waterfowl Refuge, and to determine the most important duck-food species. Ducks were examined as hunters checked through the headquarters building. Food staples were removed from the crops of these birds and numbered. The species of duck, age, sex, plumage, and date of collection were recorded. Contents of the samples were examined and identified. Plant species represented in the crop samples were tabulated by the percent frequency method, and the most important plant species determined. Food preferred by each species of duck was determined by this method. Grain sorghum (Sorghum vulgare), spikerush (Eleocharis palustris), sprangletop (Leptochloa fascicularis), barnyard grass (Echinochloa crusgalli), and purple ammannia (Ammannia coccinea) were the most important plant species.
