Recognizable at long distance when in flight, by its peculiar flight pattern and profile. Fluttering, "inefficient" wing beats, short tail, long bill and often a throat bulging with seeds.
Sound:Fairly silent. Warning call a characteristic dry and rasping "karrr karrr karr" in even pitch. Song a quiet improvisation of whistling and clappering sounds, interspersed with mimicry of other birds.

CCSmall martin with dark brown chest-band and white throat. Upperparts dark brown, underparts white. Underside of wings dark. Juveniles with light fringes to brown feathers, and buff throat. Flight more elegant than Barn Swallow and House Martin. Often changes direction but keeps altitude. More fluttering flight than House Martin, with less gliding.
Sound:Contact call a mono- or disyllabic "trrrrt". Similar to House Martin but more raucous and less crisp, with less rolling r's, and with stable pitch throughout. Song a primitive improvisation on the contact call. Alarm call similar to House Martin; a sharp plaintive "tseep", but somewhat purer and more drawn.
