The karoo korhaan (Heterotetrax vigorsii), also known as karoo bustard, is a species of bird in the bustard family, Otididae, from Southern Africa. The karoo korhaan lives in a range of arid habitats associated with the karoo and other arid scrubland habitats found in western South Africa and Namibia. It is also found in slightly denser scrubland, preferring habitat with cover ranging from 10 to 50 cm (3.9–20 in) off the ground. A small population can also be found in karoo-like fynbos habitat in the Western Cape province.
The karoo korhaan is a small bustard, 60 cm (24 in). Males are larger and heavier, weighing 1,600 g (56 oz) compared to the female's 1,350 g (48 oz). The head, neck and breast of the nominate subspecies is grey-brown, with a black chin and throat edged in white. The belly is pinkish white, and the wings are brown. The female is similar to the male but has less black on the throat. The neck and breast of the subspecies E. v. namaqua is greyer compared to the nominate subspecies.
Karoo korhaans are omnivorous, but plant material is dominant in their diet. Flowers, fruit, leaves and corms all being taken. In particular, flowers from Asteraceae, Brassicaceae and Mesembryanthemaceae are all seasonally important. Wikipedia →

Rare
Under 5% of wildlife watchers report a Vigor's Bustard sighting in De Hoop Nature Reserve on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 173rd most-seen of the 189 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Vigor's Bustard in De Hoop Nature Reserve on a given day, against under 5% in July–October and December–May, the lowest months. June has too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Vigor's Bustard sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only De Hoop Nature Reserve, in our data
De Hoop Nature Reserve is the only park on Wallace's Line with enough records to rate Vigor's Bustard sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Vigor's Bustard is recorded against all the birds logged in De Hoop Nature Reserve (10 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.
