Large lark with a strong, thick bill and an obvious pale eyebrow. Thick black patches at the neck sides can vary with posture and between individuals. In flight, dark underwings with white trailing edge to upperwings are diagnostic. "Slow-motion" wingbeats in song flight make it look bigger than it is. An inhabitant of open farmland and natural steppe. May form large flocks in winter. Jumbled song consists of trills and chips, and frequently mimics other species.
