Large owl with an orange face and big inky-black eyes. Adult is brown with extensive thin barring on the underparts. Juvenile is whitish, with barring all over the body. The closely related Brown Wood-Owl is much darker in adult plumage, with a thinly barred brown breast, and its juvenile plumage is whiter, relatively unmarked, with a more contrastingly dark brown face. Spotted Wood-Owl prefers open forests, and can sometimes be seen on fairly conspicuous perches, even when roosting. Hoots loudly and sonorously, with pairs frequently duetting.
