They are found both in urban areas and at rocky cliffs where they build nests in a way typical of all members of the order Apodiformes.

The Latin specific affinis means similar to or related to, but in this case the species that the little swift supposedly resembles is not clear from the description.

Unlike the more northerly common swift, many birds are resident, but some populations are migratory, and these winter further south than their breeding areas.

[7] The population of the species is expanding and increasing, mainly due to its tendency to build nests in man-made structures.

[8] However, in Turkey a local decline of about 50% was observed due to habitat loss resulting from dam construction.
