Ninox strenua
Description
Powerful Owls are the largest owl in Australia, with a wingspan reaching up to 140 centimetres. They are generally found in open forests and woodlands, particularly areas that include densely sheltered gullies along waterways. The breast plate of the owl has distinctive dark v-shaped chevrons.
Unusually in raptors, the male is larger than the female. Powerful Owls need old growth tree hollows to nest. They tend to mate for life, with the female incubating the eggs (usually two) and looking after the young. Young owls remain with the parents for up to a year. Mating usually occurs during the autumn / winter months.

Interesting facts
Powerful Owls need large tracts of land to survive, with a home range of up to 1000 hectares. Local populations are most at threat from land clearing and human development. While the population is considered stable, they are listed as endangered in South Australia, threatened in Victoria and vulnerable in both Queensland and New South Wales.
