Fairly common, but strictly nocturnal and infrequently seen. Favors woodland, forest, parkland, urban areas and churchyards with large trees; tends to roost well hidden in foliage during the day, when may be detected by tracking down the excited sound of small birds mobbing the owl. Comes out at night to hunt in clearings and more open areas. Most often detected by its quavering hoots and "kee-wik!" shrieks, given at night. Brown to gray-brown overall with big rounded head, dark brown eyes.
