Abstract: Foraging site selection by dabbling duck broods in constructed ponds were examined at three spatial scales: within pond, between ponds, and between pond clusters. Brood densities from 1991, 1992, and 1993 were used in analyses with plant, invertebrate, physical, and chemical measures collected in 1992. Observations on brood foraging locations were collected in 1993. Invertebrate abundance influences brood use and movements at all three scales. Pond size, location, water depth, composition of the submersed plant community, and the daily movements of invertebrates were variables that affected brood density and foraging site selection.
