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 →

No species of the same family or order lives in Ouagadougou, so these are its closest relatives here: other birds.
Possible
About 20% of wildlife watchers report a Double-spurred Francolin sighting in Ouagadougou on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 59th most-seen of the 86 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March–April, June, October and December–January
In those months about 20% of wildlife watchers report a Double-spurred Francolin in Ouagadougou on a given day, against about 10% in May, July and September, the lowest months. Those are among Ouagadougou's driest months, with about 30 mm of rain a month against 250 mm in August. February, August and November 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.
2nd of 6
Of the 6 cities where we can rate Double-spurred Francolin sightings, Ouagadougou ranks 2nd at about 20%. The best odds are in Abuja (Nigeria, about 30%).
GBIF citizen-science records
It is estimated from how often the Double-spurred Francolin is recorded against all the birds logged in Ouagadougou (14 verified sightings), 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.
