The Powerful Owl is found in forests of southeast Australia as residents. They are nocturnal, and hunt their prey during the night. Their prey are mainly small to middle-sized tree-dwelling mammals. In this illustration the owl has captured a koala cub. The female is slightly smaller than the male. Like most birds of the owl family, they make their nests in hollows of trees. The breeding season of the Powerful Owl is winter, beginning in May. They create nests in the tops of high trees in crowded forests, and lay two eggs. The female incubate the eggs, and they hatch on about the 38th day.
