Common breeding resident locally occurs from lowlands to higher hills, often near large rocky outcrops. It usually speeding through the air in search of small flying insects, as large scattered flocks, often with other species of swifts and swallows. Flying insects form their main food. The breeding season is during the first half of the year and the nest is a large cup shaped structure made up of grass, straws and feathers glued together with the bird's saliva and stuck to the roof of a cave or underside of a bridge or the like. They breeds in colonies and often use nests for the roosting as well. So birds frequent at their nesting places all the year round.
