Abstract: | Summary Avery, G., Robertson, A. S., Palmer, N.G. 4% Black-headed Heron Ardea melanocephala was the most common bird representing 14,8 % of the mass. Accipitridae (buzzards and harriers) and Tytonidae (owls represented 10,1 % of the mass. Leporidae (hares) were the most common mammals represented 10,7% of the mass. A single bone of an adult Grysbok Raphicerus melanoris represented 20,1% of the mass and was almost certanly taken as carrion. Similarities with diet data from other areas are apparent. The Giant Eagle Owl is omnivorous, its diet being determined bayrhabitat and local abundance. Comparison with the diet of Cape Eagle Owl Bubo capensis confirms that separation of habitats, with associated differences in the accessibility and availability of prey, explains the differences in prey taken by these species.Summary Avery, G., Robertson, A.
