The yellow-billed oxpecker (Buphagus africanus) is a passerine bird in the family Buphagidae. It was previously placed in the starling and myna family, Sturnidae. It is native to the savannah of Sub-Saharan Africa from Senegal east to Sudan. It is least common in the extreme east of its range where it overlaps with the red-billed oxpecker, despite always dominating that species when feeding.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the yellow-billed oxpecker in his Ornithologie based on a specimen collected in Senegal. He used the French name Le pique-boeuf and the Latin Buphagus. 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 yellow-billed oxpecker. Linnaeus included a brief description, coined the binomial name Buphaga africana and cited Brisson's work. This species is placed in the genus Buphagus that was introduced by Brisson... Wikipedia →
Rare
Under 5% of wildlife watchers report a Yellow-billed Oxpecker sighting in Niokolo-Koba National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 194th most-seen of the 215 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a Yellow-billed Oxpecker in Niokolo-Koba National Park on a given day, against under 5% in March–April, August–September and November–January, the lowest months. That is one of Niokolo-Koba National Park's driest months, with almost no rain against 300 mm in August. May–July and October have too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Yellow-billed Oxpecker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
30th of 33
Of the 33 parks where we can rate Yellow-billed Oxpecker sightings, Niokolo-Koba National Park ranks 30th at under 5%. The best odds are in Queen Elizabeth National Park (Uganda, about 40%), Masai Mara National Reserve (Kenya, about 40%) and Akagera National Park (Rwanda, about 40%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Yellow-billed Oxpecker that you can see in Niokolo-Koba National Park (order Passeriformes, Perching Birds) are Long-tailed Glossy Starling (about 90%), Yellow-crowned Gonolek (about 70%) and Common Bulbul (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-billed Oxpecker is recorded against all the birds logged in Niokolo-Koba National Park (13 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.
