north coast of Sea of Okhotsk, Russia.
Recent reviews and analyses#R#R#R#R suggest that two taxa long associated with present species merit separate species status as, respectively, P. examinandus and P. xanthodryas (see both), but that long-standing race kennicotti (W Alaska) should not be recognized. Other proposed races are talovka (Scandinavia E to S Siberia and NW Mongolia), transbaicalicus (E Siberia and N Mongolia) and hylebata (NE China and SE Russia S to N Korea). Monotypic.
N Europe (N & E Fennoscandia, N Russia) E through N Siberia to R Kolyma and Russian Far East (excluding Kamchatka), S to SC Siberia (L Baikal), Mongolia and NE China (NE Inner Mongolia, Heilongjiang), also NW USA (W Alaska); non-breeding SE Asia (S Myanmar E to Vietnam), SE China (Fujian, N Guangdong) and Taiwan S to Sundas and Moluccas.
