This a fairly common bird found from India to the Philippines and all through SE Asia. The swift enjoys an open area and farmland makes it easy for them to be spotted . They have a deep fork in their tail and spend most of their lives flying through the air catching insects while in flight, they will never really touch the ground at all. Their lives are truly in the air with them clinging to rock faces and cracks when they need to rest.
Their nest is quite uniquely made with it being made on the underside of a palm leaf put together with their own saliva. If they do need to drink they will do it in flight and skim over the water they want. They are superb fliers.
