Subspecies
Sometimes included in Besra (Accipiter virgatus), but full species status now generally agreed upon. They probably form a superspecies, possibly along with Dwarf Sparrowhawk (Accipiter nanus). Subspecies sometimes rejected, and species considered monotypic.
The following 3 subspecies are recognised:
sibiricus Stepanyan, 1959 - Upper R Ob and Mongolia east to middle R Lena, eastern China and Taiwan; presumably winters from Andaman and Nicobar Is east to southern China and Greater Sundas.
gularis (Temminck & Schlegel, 1844) - Sakhalin, southern Kuril Is and Japan. Winters south to Philippines, Greater Sundas, northern Sulawesi and Timor.
iwasakii Mishima, 1962 - Southern Ryukyu Is (Iriomote, Ishigaki).
