[edit] Taxonomy

[edit] Subspecies

Passer simplex has three subspecies:1

  • P. s. saharae
  • Sahara of south-eastern Morocco to Algeria, southern Tunisia and central Libya. New work shows that this subspecies may be invalid and has to be lumped into simplex.
  • P. s. simplex
  • Southern Sahara from Mali to northern Niger (Aïr Massif), northern Chad and central Sudan
  • P. s. zarudnyi
  • Deserts of south-central Asia (eastern Iran, Uzbekistan and Turkmenistan)
  • Split by Sibley & Monroe2 as Asian Desert Sparrow. New scientific work3 supports the split and introduces a new name, Zarudny's Sparrow.

[edit] Habitat

Sandy plains at desert edge; also oases and settlements.

[edit] Behaviour

An erratic species, at times common in an area and absent in another.

[edit] Diet

Feeds an seeds of desert bushes and ground vegetation. Nestlings are fed with insects.
Forages in pairs or small groups collecting food on the ground.

[edit] Breeding
