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:

Dark blue metallic upperparts, deep red forehead and throat and light underparts. Long tail-streamers in adults and deeply forked tail. Both the metallic blue and the deep red appears black at a distance. Combination of dark throat/breast and light underparts and vent is diagnostic, and distinguishes it both from Red-rumped Swallow and the smaller martins. Juveniles are less brightly coloured with a dull red throat, and short streamers.

Sound:

Characteristic calls and song. Contact call a short and sharp "weet" or "kee-weet". Song a sparkling, squeaky energetic improvisation with interspersed contact calls, often with diagnostic ending; an electric and drawn-out "su-eerrrrrrrrrrrrrrr".
