Bubo africanus (Spotted Eagle-Owl)

Wikipedia Abstract

The spotted eagle-owl (Bubo africanus) is a medium-sized species of owl, one of the smallest of the eagle owls. Its length is 45 centimetres (18 in) and its weight is from 480 to 850 grams (1.1 to 1.9 lb). It has a 100 to 140 centimetres (39 to 55 in) wingspan. The facial disk is off white to pale ochre and the eyes are yellow. It has prominent ear tufts, and the upper body is dusky brown, the lower parts off-white with brown bars. Prior to 1999 the spotted eagle-owl was considered conspecific with the greyish eagle-owl, but now it is classed as a separate species.
