Which bird of the family "Tytonidae" is in the picture?

The greater sooty owl ("Tyto tenebricosa") is a medium to large owl found in south-eastern Australia, Montane rainforests of New Guinea and have been seen on Flinders Island in the Bass Strait.

The lesser sooty owl ("T. multipunctata"), is sometimes considered to be conspecific with this species, in which case they are then together referred to as sooty owls. It is substantially smaller and occurs in the wet tropics region of North Queensland, Australia.

Greater sooty owls are nocturnal and roost in large tree hollows, caves and in dense foliage during daylight hours. Rarely seen or heard, they can be found in areas with deep gullies in moist forests, where smooth-barked gum trees, tree ferns and wet forest under-storey are present. They may hunt in drier areas but usually roost and breed in the moister areas.

Mammals, ranging from large arboreal marsupials such as the greater glider, through ringtail possums and sugar gliders, to bandicoots, rodents, and antechinus comprise the most common items in the greater sooty owl diet. They also occasionally take birds, bats, and insects.

Greater sooty owls are territorial and are thought to remain in the same area throughout their adult lives. Sooty owls have a distinctive range of calls including typical barn owl like rasps and screams, a distinctive "falling bomb" call and an insect like twitter used during close contact with other sooty owls.
