The Powerful Owl is the largest strigid in Australia, and the most impressive of its entire genus. It is restricted to the eastern seaboard of Australia, where the species occurs from southern Queensland south to Victoria, with a single record from South Australia, and comparatively few records west of the Great Divide. This Ninox clearly favours old-growth forests, both wet and dry sclerophyll, and routinely nests in tall, hundreds of years old trees, but has apparently adapted to areas impacted by logging and habitat fragmentation, clearly accepts a degree of urbanization, and is tolerant of some human intrusion into its habitat. It is possible that the availability of suitable nest sites and reasonably abundant prey, which is centered on mammals, especially marsupials, but also includes birds to varying degrees, are the key factors determining this owl’s distribution. Powerful Owl is listed on the Red Lists of all three key Australian states across its range—Queensland, New South Wales, and Victoria—and estimated numbers are clearly rather small, probably just a few thousands of individuals, but overall the species’ global conservation status is estimated as Least Concern by BirdLife International.
