Abstract

ABSTRACT: Sex differences in foraging can be explained by avoidance of competition, reproductive strategies or breeding roles. We investigated foraging behavior and potential intersexual differences in the Restinga Antwren over the year, recording foraging tactics, their timing, substrate and their height above the ground. We found significant differences between sexes in foraging tactics, substrates and height of foraging. Females foraged mostly on the ground while males in the middle and top of the vegetation. Smaller differences in foraging height between sexes in the breeding season compared with non-breeding season support the reproductive strategies model, although the avoidance of competition cannot be excluded.
