Abstract:
Coexisting Crowned Plovers Vanellus coronatus and Blackwinged Plovers V. melanopterus were studied to determine whether niche partitioning occurred or was necessary to facilitate their coexistence. The results of this study show that niche partitioning did not occur. We suggest that the association of these two species potentially enhances the ability of each to detect and avoid predation, in spite of any possible deleterious effect of interspecific competition (e.g. reduced per capita food intake).
