Subspecies
Sylvia crassirostris (Sibley and Monroe 1990, 1993) has been split into Eastern Orphean Warbler (Sylvia crassirostris) and Western Orphean Warbler (Sylvia hortensis) on the basis of differences in coloration, biometrics and mt-DNA (Shirihai et al. 2001), to which Baerlein et al. (2006), although they did not accept the split, added moult pattern. However, the colour differences are minor, the biometric differences (as independently presented in Cramp 1992) show much overlap, the vocal differences are not particularly strong (and with no indication whether they converge where the ranges converge), the moult pattern is difficult to evaluate taxonomically, and the molecular evidence remains unpublished after at least six years. Therefore this split is not accepted by BirdLife International until better evidence is provided.

Considered by some authors to be a subspecies of Western Orphean Warbler (Sylvia hortensis).

The following 3 subspecies are recognised:

  • crassirostris (Cretzschmar, 1826)   -  South-eastern Europe to central Asia. Considered by some authors to be a subspecies of Western Orphean Warbler (Sylvia hortensis).
  • balchanica Zarudny & Bilkevitch, 1918   -  Breeds from south-western Caspian Sea region and north-eastern Iraq east to south-eastern Turkmenistan and south-eastern Iran. Non-breeding southern Iran, southern Pakistan and south-eastern Arabia (United Arab Emirates, Oman). Considered by some authors to be a subspecies of Western Orphean Warbler (Sylvia hortensis).
  • jerdoni (Blyth, 1847)   -  Breeds southern Kazakhstan, eastern Uzbekistan and western Kyrgyzstan south to Afghanistan, also extreme south-eastern Iran and western Pakistan. Non-breeding India. Considered by some authors to be a subspecies of Western Orphean Warbler (Sylvia hortensis).
