Alauda is a genus of larks with four 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. These birds are 14–18 cm long and live in cultivation, heath, natural steppe and other open habitats. The long, unbroken song is a clear, bubbling, warble delivered high in the air while the bird is rising, circling or hovering.
