- Tail brown with white edges.
- Sexes are similar
Juvenile
- White-spotted brown upperparts, head and face

Distribution
Circumpolar; tundra, and south in mountain plateaux, plains and semi-deserts to the Atlas Mountains in northwest Africa, the Balkans in Europe, the Zagros and Himalaya in Asia, and the northernmost Andes in the Americas. Arctic populations are strongly migratory, while southern mountain populations are resident or short-distance altitudinal migrants.
Taxonomy
Complex. The currently accepted broad circumscription of a single species with 42 subspecies[1] has recently been shown to leave the species paraphyletic with respect to the closely related Temminck's Lark[2]; a split into six species (as arranged below) is likely to be accepted formally in the near future.
Of interest as the sole species of a diverse Old World family to have colonised the New World; a similar example in reverse is the Eurasian Wren.
