Silhouette: Amanda Kuhlman · PhyloPic
The red-billed spurfowl (Pternistis adspersus), also known as the red-billed francolin, is a species of bird in the family Phasianidae. It is found in Southern Africa, including Angola, Botswana, Namibia, South Africa, Zambia, and Zimbabwe.
The species exhibits sexual dimorphism in size. Males are larger, measuring 38 cm (15 in) in length and weighing 340–635 g (12.0–22.4 oz), whereas females measure 33 cm (13 in) in length and weigh 340–549 g (12.0–19.4 oz). The species has barred underparts (in contrast to the related Natal spurfowl) and a conspicuous yellow eye-ring.
The red-billed spurfowl was described in 1838 by the English naturalist George Robert Waterhouse from specimens collected by James Edward Alexander on his expedition to Namaqualand and Damaraland. Waterhouse coined the binomial name Francolinus adspersus and noted that the specimens had come near the Fish River in what is now Namibia. The specific epithet adspersus is Latin for "sprinkling". The species is now placed in the genus Pternistis that was introduced by the German naturalist Johann Georg Wagler in 1832. The red-billed spurfowl is considered as monotypic: the proposed subspecies mesicus is not... Wikipedia →

Very likely
Over 90% of wildlife watchers report a Red-billed Francolin sighting in Waterberg Plateau Park on a given day, based on 204 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 118 birds we can rate there.
May and August–December
In those months over 90% of wildlife watchers report a Red-billed Francolin in Waterberg Plateau Park on a given day, against about 80% in February and July, the lowest months. Those are among Waterberg Plateau Park's driest months, with about 15 mm of rain a month against 110 mm in January. April and June have too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Red-billed Francolin sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Red-billed Francolin sightings, Waterberg Plateau Park has the highest daily chance: over 90%. Next come Moremi Game Reserve (Botswana, about 70%) and Chobe National Park (Botswana, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Red-billed Francolin is recorded against all the birds logged in Waterberg Plateau Park (204 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.
