Shelley's Eagle-Owl Ketupa shelleyi

Very large, dark rainforest owl. Note the dark brown upperparts, heavily barred underparts, and dark eyes. Rare and local in lowland rainforest, including forest edge. The call is a single long, descending whistle: “hrroooooouw,” repeated after long pauses. Shelley’s Eagle-Owl is much larger than other rainforest eagle-owls. Overall coloration most similar to Akun Eagle-Owl, but Shelley’s has dark rather than yellow eyes. Similar in size to Verreaux’s Eagle-Owl, but darker and heavily barred below.
