Body length: 14-15 cm. Breeds in caves and cavities on cliff faces, rarely also in holes in buildings and walls. Found at all levels, even high up in remote mountain areas. Migrant in N, resident or short-distance migrant in S.

Identification: Rather large and compact swallow with heavy body, broad neck and broad but pointed wings. Drab-grey-brown above with flight-feathers a shade darker, and dirty brown-tinged greyish-white below on breast and gradually darkening rearwards towards undertail-coverts. At moderate range and in good light, throat is seen to be faintly streaked or dusky. Underwing pattern characteristic, with rather pale brown-grey remiges and clearly contrasting sooty-black coverts. An important character is visible only when the shallow forked tail is spread: small white windows on most tail-feathers. Flight powerful and agile, often glides on flat wings held straight out, twists and turns, sweeps rapidly along, gives a few quick beats, and so on. Often seen high up in air like a swift, or patrolling back and forth along vertical cliff high in mountains. Juvenile: Same plumage differences as for Sand Martin.
