Distribution

Africa and Asia
In Africa south of the Sahara, locally also Northern Africa. In the Middle East in Israel and Turkey. From there east to Iran, Pakistan and India.

Northernmost populations migratory in for example Middle East.

Taxonomy

Forms a superspecies with House Swift Apus nipalensis and is often considered conspecific. Sometimes also called House Swift (and the House Swift is sometimes called Little Swift) so confusion is easily possible.

Behaviour

Breeding

Diet
