Typical Owls (Strigidae)

Japanese Scops-owl (Otus semitorques) - HBW 5, p. 158

French: Petit-duc du Japon German: Japan-Zwergohreule Spanish: Autillo Japonés

Taxonomy: Otus semitorques Temminck and Schlegel, 1844, Kyushu, Japan.
Probably forms superspecies with O. mentawi, O. bakkamoena, O. lettia, O. lempiji, O. fuliginosus and O. megalotis. Formerly treated as subspecies of highly variable O. bakkamoena, but significant differences in vocalizations, as well in eye colour, indicate separate species. Sometimes considered to include race ussuriensis of O. lettia, which closer to present species in voice and plumage characters, and also intermediate in eye colour; possibly better included as race of present species. Two subspecies recognized.
