Probably forms superspecies with O. senegalensis, O. scops, O. sunia and O. flammeolus. Has often been considered race of O. scops or O. sunia, but significant differences in voice and morphology, and no hybridization in areas of range overlap. Socotran form socotranus and Arabian pamelae currently placed with O. senegalensis, but sometimes included with present species, or may be specifically distinct. Geographical boundaries of races unclear, with apparent intergradation, and individuals showing intermediate characters (e.g. bet.. View all taxonomy...

Taxonomy: Ephialtes Brucei Hume, 1873, Rahuri, Ahmednagar, Maharashtra.
Probably forms superspecies with O. senegalensis, O. scops, O. sunia and O. flammeolus. Has often been considered race of O. scops or O. sunia, but significant differences in voice and morphology, and no hybridization in areas of range overlap. Socotran form socotranus and Arabian pamelae currently placed with O. senegalensis, but sometimes included with present species, or may be specifically distinct. Geographical boundaries of races unclear, with apparent intergradation, and individuals showing intermediate characters (e.g. between obsoletus and exiguus); Turkish birds sometimes placed in exiguus; obsoletus and semenowi sometimes considered only intergrades between races. Four subspecies recognized.

Subspecies and Distribution:

  • brucei (Hume, 1873) - E Aral Sea to Kirgizia and Tadjikistan.
  • obsoletus (Cabanis, 1875) - S Turkey, N Syria, N Iraq, Turkmeniya, Uzbekistan and N Afghanistan.
  • semenowi (Sarudny & Härms, 1902) - S Tadjikistan and W China (E to C Tarim Basin) S to E Afghanistan and N Pakistan.
