[edit] Taxonomy
Separation of Apus pallidus from Common Swift Apus apus, is discussed at length here.
There are three races generally recognised.
Nominate pallidus is found from inland North Africa and the Middle East to Iran and Pakistan is pale greyish-brown with extensive white throat.
Brehmorum from the Canary Islands to Cyprus and Turkey including coastal North Africa is darker and browner with a reduced throat patch.
The darkest race is illyricus from around the eastern Adriatic.
Race illyricus has occurred in Denmark as a vagrant and the first Scottish record, in Orkney in 1996, appeared to belong to race brehmorum.

Coastal and river valleys.
[edit] Behaviour
Feeds over open country and towns, breeds in crevices in buildings or cliffs.
