Stratal distribution and resource partitioning of birds in the Knysna Forest, South Africa

Habitat subdivision and resource partitioning of the birds of the evergreen high forest of the southern Cape are investigated. Most species utilize a wide stratal range with insectivores predominating in the lower strata and mixed-feeders and frugivores in the upper strata. Members of the respective foraging guilds used a different stratum or were separated by differences in morphology or mass, suggesting different sized prey and limited competition.
