Greater sooty owls are nocturnal and roost in large tree hollows, caves and in dense foliage during daylight hours.

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.

[7] Greater sooty owls are territorial and are thought to remain in the same area throughout their adult lives.

The female roosts in the nest for several weeks before she lays one or two dull white eggs.

Usually nesting commences from January through June but could occur at almost any time of the year depending on location and climatic conditions.
