Large-billed lark


The large-billed lark or southern thick-billed lark is a small passerine bird found in southern Africa. The name "large-billed lark" may also refer to Bradfield's lark. The name "thick-billed lark" more commonly refers to the species of the same name.

Taxonomy and systematics

The large-billed lark was originally placed in the genus Alauda, and then Calendula until that genus was subsequently re-named to the present Galerida. Another alternate name used for the large-billed lark is the long-billed lark.

Subspecies

Three subspecies are recognized:
The large-billed lark is 18 cm in length. It is relatively short-tailed and has a thick bill with a yellow base to the lower mandible. It has streaked brown-grey upperparts, and a long white supercilium. Like other species in the genus, it has a crest that can be raised in display or alarm. The underparts are cream-coloured with heavy dark streaking on the breast. The heavy bi-coloured bill distinguishes this species from all other African larks.
The call of this very vocal species is a soft creaking "treeeeleeeeleee".

Distribution and habitat

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.

Behaviour and ecology

Like other larks, the large-billed lark nests on the ground. Its food is seeds and insects, the latter especially in the breeding season.
