Treść dostępna tylko w języku angielskim
The bar-tailed lark, or bar-tailed desert lark, is a species of lark in the family Alaudidae. Two other species, the rufous-tailed lark and the Cape clapper lark are both also sometimes referred to using the name bar-tailed lark. It is found from Morocco to Pakistan. Its natural habitat is hot deserts. This is in many places a common species, but elsewhere rather less common. It has a very wide distribution and faces no obvious threats, but surveys have shown that it is slowly decreasing in numbers. The International Union for Conservation of Nature has rated its conservation status as being of "least concern".

The upper parts are sandy-buff washed with grey, while the underparts are whitish with little if any streaking, and the breast and flanks washed with buff. The rufous wings have dark trailing edges and the rufous tail has a terminal black band.
