A small, compact lark with dark brown upperparts that appear scaly in fresh plumage, a streaked crown that can be raised as a crest, an indistinct tawny eyebrow, a striking pale throat, and a pale belly with dark breast streaks. The bill is bicolored: pale below with a dark ridge on the upper mandible. The tail is mostly dark with white outer feathers that are conspicuous in flight. Movements of this very localized lark are poorly known, but small groups are probably partial migrants and nomads in dense grassland with scattered bush; likely often goes undetected when not singing. Best identification feature is the diagnostic song, a single-note strident loud up-and-down “wheeeeoooo” whistle, repeated incessantly every two seconds for minutes at a time.
