Small brown owl with large dark eyes and small, soft-looking ear tufts. Dark brown, almost black, eyes separate it from otherwise similar species such as Mountain, Oriental, and Rajah scops-owls. Reddish Scops-Owl is also dark-eyed, but it is darker-faced and tinged with rufous overall. Like most other small scops-owls, Sunda is more readily heard than seen: it gives yelping hoots at widely-spaced intervals. Relatively tolerant of human habitation; often encountered in gardens, plantations, and parks, as well as forests.
