Agulhas Long-billed Lark

The Agulhas long-billed lark, or Certhilauda brevirostris, is a modestly sized passerine bird, measuring 18–20 cm in length. It is characterized by its long tail and a somewhat curved bill. The bird's plumage is a blend of streaked buff-grey on the head and back, while its wings, when closed, present a grey hue. The underparts are a creamy color, adorned with dark streaking across the breast and flanks. This species can be distinguished from the Cape long-billed lark by its more buff coloration and comparatively shorter tail and bill.

Identification Tips

When attempting to identify the Agulhas long-billed lark, look for its long tail and curved bill, which are key features. The streaked buff-grey head and back, along with the grey wings and cream-colored underparts with dark streaks, are also indicative. Its shorter tail and bill set it apart from the similar Cape long-billed lark.

Habitat

The Agulhas long-billed lark's natural habitat is somewhat of a mystery, as much of its range has been transformed into stony wheatfields and pasture land. Only about 30% of its habitat remains as coastal fynbos or karoo scrub. Despite this, the species seems to have adapted well to the agricultural landscapes it now frequently inhabits.

Distribution

This bird is endemic to South Africa, with its range focused around the Agulhas arable farmlands. Its distribution extends from east of the Hottentots-Holland mountain range to Mossel Bay, covering an area no larger than 15,000 km².

The Agulhas long-billed lark's behavior and ecological preferences are not well-documented. However, it is known to nest on the ground, as is typical of larks.

Song & Calls

The display song of the Agulhas long-billed lark is a distinctive disyllabic whistle, which can be phonetically described as "seeooo seeeooo."

Breeding

The diet of the Agulhas long-billed lark consists of seeds and insects, with a preference for the latter during the breeding season.

Conservation status

The conservation status of the Agulhas long-billed lark is not explicitly mentioned, but given its restricted range and adaptation to modified habitats, its status warrants monitoring.
