Alauda is a genus of larks with three species found across much of Europe, Asia and in the mountains of north Africa, and one species (the Raso Lark) endemic to the islet of Raso in the Cape Verde Islands.
They are fairly undistinguished: streaked brown above and pale below, with a short, blunt, erectile crest. In flight, they display a short tail and short broad wings. The tail and the rear edge of the wings are edged with white.
