BUBO AFRICANUS - THE SPOTTED EAGLE OWL
Nocturnal hunters, the spotted eagle owl spends most of the day concealed in trees, rock ledges or abandoned burrows. The Spotted Eagle Owl is a medium to large owl with prominent ear tufts. The upper-parts of the body are dusky brown with pale spots, the under-parts are whitish and finely barred.
Despite being one of the smaller eagle-owl species, the spotted eagle owl has an impressive one metre wingspan. The facial disk is whitish to pale ochre and the eyes are yellow. The Spotted Eagle owl can easily be mistaken for the Cape Eagle owl. Differences are the yellow eyes, smaller claws and striped legs.
