The Kenyan, or Mackinder’s eagle owl, is a subspecies of the eagle owl. Mackinder’s eagle owls in central Kenya are generalist predators capable of exploiting an agricultural niche that is devoid of most other predators.  

This is a large owl, (the largest of the eagle owls), though intermediate in size among other large Bubo owls. Its total length ranges from 46 to 61 cm (18 to 24 in). Males weigh from 905 to 1,387 g (1.995 to 3.058 lb) while the larger females range from 1,240 to 1,800 g (2.73 to 3.97 lb).[4] The wing chord measures 34.3–41.8 cm (13.5–16.5 in) while the tail measures 15.5–26.6 cm (6.1–10.5 in). This owl is dark brown above with prominent ear-tufts and yellow or yellowish-orange eyes. It is dark below with the sides of the breast being blotchy brown and the paler chest overlaid with white, black and tawny-fulvous markings, variously. The facial disc is fulvous-brown, with a distinct black or dark brown frame that becomes broader towards the neck. Both the tail and wing feathers are barred with light and dark brown. The toes and tarsi are densely feathered, with the little visible skin being brown above and yellowish below the feet.

The song of the male Cape eagle-owl consists of a powerful, explosive hoot, followed by a faint note: boowh-hu.[4] The female’s voice is similar but slightly higher pitched. Pairs on occasion will duet. When alarmed, both sexes let out a barking wack wack wack.
