Appearance:

Approaching Eagle Owl in size, but shape more elongated, with head being extremely large. Differs from Ural Owl in yellow eyes, concentric markings in facial disks, bold white bars between eyes and black "beard". Wings and tail long. Characteristic pale patch at base of primaries shows in flight, but the species leaves an overall darker impression than Ural Owl. Tail with dark terminal band.

Sound:

Song: Cyclic, repetitive, very deep calls rising and falling in volume. Accented start and end of each "hooh". As the call fades away in volume, the speed accelerates. Sometimes disyllabic "ho-ho,ho-ho,ho-ho,ho-ho".

Appearance:

Slate grey upperparts with barred white underparts. Female and juvenile sometimes rufous brown. Male with defined grey breast in contrast to barred white belly, female with diffusely barred chest and throat. Yellow iris and thin bill. Wings and tail long and slender, often giving the impression of a small falcon. Often perches with a more horizontal posture than hawks or falcons, i.e. tail pointing backwards and not towards the ground, and drooping wings. In flight wings are not raise above horizontal plane, and it seldom glides like raptors.

Sound:

Song: the well known disyllabic "cuck-coo" with emphasis on first note, and the second note a third lower than the first one. Also a harsh "tchaa tchaa", and a bubbly trill, reminiscent of Little Grebe, uttered by the female.

Male:
