Tyto tenebricosa Gould, 1845

Dark eyes set in a round facial disc. The upperparts are sooty black, finely spotted white on the head with larger but sparser white spots on the wings. The Facial disc is large, round and sooty black through to dark grey or silver and is heavily edged black. The underparts vary from sooty black to dark grey, (never as dark as the upperparts) finely spotted with white. The Belly is always paler than the breast. The tail is very short, the legs feathered and eyes very large with a black iris. A Sooty Owl's Bill is horn coloured and feathered almost to the tip. Toes are dark grey and the large talons black. Sexes are similar in plumage and Females are usually slightly larger than males. They are distinguished from lesser Sooty Owls by much larger size and darker plumage, sparser white spots on upperparts and darker underparts which have white spots on a dark background where the lesser Sooty Owl has dark chevrons on a pale background
