, 1859,

Sahara of southern Algeria

.

Form named as S. ticehursti, described on basis of single specimen from S Morocco (near Ouarzazate), and traditionally treated either as separate species or as race of present species, is probably an aberrant individual of race maroccana (which it resembles in general structure and in tail and tertial patterns), or a hybrid between it and S. deserti (which it resembles in having pale sandy-brown upperparts). Two subspecies recognized.

Subspecies and Distribution
  • S. d. maroccana E. J. O. Hartert, 1917 – Anti-Atlas and High and Middle Atlas, from Jebel Igdet (Morocco) E to Tlemcen (NW Algeria); non-breeding also S to W Sahara oases (as far S as Nouakchott, in W Mauritania).
  • S. d. deserticola Tristram, 1859 – Saharan Atlas and Aurès Mts, from Aïn Sefra (NW Algeria) E to Gafsa area (Tunisia); non-breeding also S to C & S Algeria (Tademaït Plateau, Tassili n-Ajjer, Ahaggar Mts), NE Mali and C Libya.
