Distribution and habitat

Endemic to southern Africa, occurring from central Namibia though to the Northern Cape, Western Cape and the Free State Province. It generally prefers semi-arid dwarf shrubland (such as Karoo) and grassy shrubland on boulder-strewn plains and rocky ridges.

Food 

It mainly eats insects supplemented with seeds, plucking food items from beneath stones and the bases of plants. It is a pest for farmers, as it sometimes digs up planted grains. The following food items have been recorded in its diet:

  • Insects
  • Arachnids
  • Seeds of shrubs
    • Augea capensis
    • Hermannia
    • Limeum
    • Osteospermum
  • Fruit and seeds
    • Atriplex semibaccata (Australian saltbrush)
    • Lycium (honey-thorns)

Breeding

  • The nest is cup built of roots and twigs and lined with the fluffy seeds of the Karoo rosemary (Eriocephalus). It is typically placed in a shallow excavated hollow at the base of a shrub or stone.
  • It lays 2-3 eggs, usually in the months from August-April.
  • The chicks are fed by both parents, becoming independent several weeks after leaving the nest.

Threats

Not threatened, in fact it is the most common long-billed lark species.
