The foraging behavior, comparing sexes foraging on and off the pond in a large enclosure is described and the effect of physical characters is shown. Foraging rate in the enclosure was considerably lower than previously reported for this sp. in the wild. The sexes did not differ in foraging rate. Phenotypic characters were correlated only weakly with foraging rate, but weight was significantly positively correlated with how often males foraged, while fat content correlated negatively. Foraging rate was also correlated with time of day.
