The name "thick-billed lark" more commonly refers to the species of the same name (i.e. Rhamphocoris clotbey).

The heavy bi-coloured bill distinguishes this species from all other African larks.

The large-billed lark is a resident breeder in southern South Africa, Lesotho and southernmost Namibia.

Its natural habitat is fynbos, karoo scrub and mountain grassland.

The large-billed lark is also found in cultivated and fallow agricultural land.
