Chunky, large-billed lark of desolate sandy deserts and open arid plains from the western Sahara east to the Arabian Peninsula. Plain sandy-brown above and paler below, with faint and indistinct white markings on the face. Also note pinkish bill and inky black outer tail feathers, which are most apparent in flight. Generally similar to other desert larks, such as Desert Lark, Bar-tailed Lark, and Kordofan Lark, but combination of unmarked upperparts, black tail feathers, and the uniformly pink and bulbous bill is diagnostic. Runs about on the ground singly or in pairs (larger groups only during non-breeding season), stopping abruptly. Song, a series of beautiful burbling phrases, is given both from the ground and in song flight. Calls include a low, wet rattle and a mellow two-note whistle.
