Medium-sized owl with significant variation in plumage and vocalizations across its large range. Either gray or brown in coloration, with prominent pale ear tufts and pale face outlined in black. Fond of open wooded habitats from lowlands to foothills, often found roosting in temples, houses, and gardens, particularly in rural areas. Larger and more strongly tufted than both Oriental and Mountain Scops-Owls; both also lack the black facial border. Taiwan birds give an incisive, short hoot every 4-10 seconds.
