 The powerful owl (Ninox strenua), also known as powerful boobook, is a species of owl native to south-eastern and eastern Australia, the largest owl on that continent. The powerful owl lives permanently in breeding pairs once in adulthood. These owls have been observed roosting singly, in pairs and in family groups of 3 to 4. They frequently roost during the day on branches in tall, open trees, often while still holding the prey caught the prior night.
