The Cape long-billed lark (Certhilauda curvirostris), also known as the Cape lark, Cape longbill or long-billed lark is a species of lark in the family Alaudidae. It is found in south-western Africa. Its natural habitats are semi-arid Karoo shrub and subtropical dry shrubland and subtropical or dry lowland and highveld grassland. This lark is also found in croplands, farmlands and coastal fynbos.
The Cape long-billed lark was formally described in 1783 by the French naturalist Johann Hermann under the binomial name Alauda curvirostris. The specific epithet combines the Latin curvus meaning "curved" or "bent" with -rostris meaning "-billed", from rostrum meaning "beak". Hermann based his account of "Le Sirli" from the Cape of Good Hope area of South Africa that had been described in 1778 by the French polymath, the Comte de Buffon in his book Histoire Naturelle des Oiseaux. An engraving by François-Nicolas Martinet was published to accompany Buffon's account. The Cape long-billed lark is now one of five larks placed in the genus Certhilauda that was introduced in 1827 by the English zoologist William Swainson.

Possible
About 30% of wildlife watchers report a Cape Lark sighting in De Hoop Nature Reserve on a given day, based on 143 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 65th most-seen of the 189 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January and November
In those months about 40% of wildlife watchers report a Cape Lark in De Hoop Nature Reserve on a given day, against about 10% in May and December, the lowest months. June has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cape Lark sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Cape Lark sightings, De Hoop Nature Reserve has the highest daily chance: about 30%. Next come West Coast National Park (South Africa, under 5%).
Same family: Alaudidae
The closest relatives of the Cape Lark that you can see in De Hoop Nature Reserve (family Alaudidae, Larks) are Red-capped Lark (about 30%) and Large-billed Lark (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cape Lark is recorded against all the birds logged in De Hoop Nature Reserve (143 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
