výreček obří Otus gurneyi

The largest scops-owl. Inhabits lowland and lower-elevation montane forest. Brown above and whitish below, with dark teardrop-shaped streaks on the chest and sides, a white V-shape between the eyes, a facial disk with a dotted black border, and orange around the large eyes. Occurs together with Everett’s and Mindanao Scops-Owls, but Giant is much larger and has much bolder marks on the chest. Gives several different vocalizations, including a loud descending screech, a ringing nasal note, and a harsh rasping note.
