Recently described S. omanensis is a synonym of present species#R#R. Differs from apparently closely related S. hadorami in its distinctive voice (in all four types compared: compound hooting, pulsed hooting, alarm calls and contact calls), notably in pitch (3) but also in temporal structure (3); differently coloured facial disc (bicoloured dark grey and grey vs uniformly whitish, buffish or grey) (2); vague thin long streaks vs vague thin short bars on underparts (2); dark greyish-brown upperwing with weak paler markings vs greyish to brownish upperwing with stronger pale markings (1); only two obvious bars vs three or four on undertail (ns[1]); broad dark wingtips and trailing edge vs pale tips of wings (ns[1]). Monotypic.
