Red-rumped Swallow/ Masjid-ababil is the size of a sparrow and is a glossy deep blue with a white chest and lower parts streaked with brown. A chestnut band runs from the face to the hindneck. The tail is long and forked that becomes visible in flight as does the red-brown rump. The flight is swift and graceful with the forked tail assisting in the flying maneuvers as it catches insects in flight. Makes nests of mud collected from rain-puddles that is then used for plastering. The mud plastered nest is usually reinforced with grass and stuck against the ceiling of an overhanging rock or even an occupied dwelling.
