Medium-sized owl with a heart-shaped facial disc and deep dark eyes. Varies somewhat across a wide range, but always note white-and-black speckling on the upperparts, beautiful gray-and-tawny wings, and large round head with ghostly white facial disc. Compared with various other masked-owls and grass-owls that overlap in range, Eastern Barn generally has a brighter white face. Hunts in open areas by night, foraging with a slow and buoyant flight. Roosts in old buildings, tree hollows, caves, and nest boxes by day. Gives a bone-chilling, rising shriek, as well as shorter rasping calls.
