This species occurs in hilly country with rocks, gorges and ravines, caves and cliffs (Jennings 2010, Aspinall and Porter 2011). It is habituated to human presence and regularly occurs in towns and cities, where concrete and high-rise buildings offer attractive nesting sites (Jennings 2010, Aspinall and Porter 2011). The species favours arid environments and avoids forested and humid areas (Jennings 2010). It occurs in pairs during the breeding season, but forms small flocks of up to 30 individuals during winter; these flocks range far away from the breeding areas and are regularly found over wetlands with high food availability (Jennings 2010). It feeds almost exclusively on flying insects (Jennings 2010). The breeding season is highly synchronized among years and regions and always peaks between February and April, when two to four eggs are laid (Jennings 2010). Nests are cups constructed of mud, which is collected from damp soils or puddles, and are lined with feathers, grass, hair, sheep's wool and thin plant downs (Jennings 2010). They are attached to vertical surfaces, e.g. in rock crevices and caves, under rock protrusions, but are increasingly placed on man-made structures like concrete buildings (Jennings 2010). Nests can be re-used in consecutive years (Jennings 2010).
