The double-spurred spurfowl (Pternistis bicalcaratus) is a gamebird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. Like most spurfowls, it is restricted to Africa. It is a resident breeder in tropical West Africa, but there is a small and declining isolated population in Morocco.
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the double-spurred spurfowl in his Ornithologie, based on a specimen that had been collected in Senegal. He used the French name "La Perdrix du Sénégal" and the Latin "Perdix Senegalensis." Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766, the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the double-spurred spurfowl. Linnaeus included a brief description, coined the binomial name Tetrao bicalcaratus and cited Brisson's work. The specific epithet bicalcaratus combines the Latin bi meaning "two" and calcaris meaning "spur". The species... Wikipedia →

Likely
About 60% of wildlife watchers report a Double-spurred Francolin sighting in Niokolo-Koba National Park on a given day, based on 256 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 215 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
February and September
In those months about 70% of wildlife watchers report a Double-spurred Francolin in Niokolo-Koba National Park on a given day, against about 30% in April, the lowest month. Those are among Niokolo-Koba National Park's wettest months, with about 110 mm of rain a month against almost none in January. May–July and October have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Double-spurred Francolin sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Niokolo-Koba National Park, in our data
Niokolo-Koba National Park is the only park on Wallace's Line with enough records to rate Double-spurred Francolin sightings: about 60% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Double-spurred Francolin is recorded against all the birds logged in Niokolo-Koba National Park (256 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.
