The oriole finch (Linurgus olivaceus) is a small passerine bird in the finch family. It is found in Africa and is native to Burundi, Cameroon, Democratic Republic of the Congo, Equatorial Guinea, Kenya, Malawi, Nigeria, Rwanda, South Sudan, Tanzania and Uganda. It lives in subtropical or tropical moist evergreen montane forests.
The male has a black head, a yellow body, black flight feathers and a stout bright yellow-orange conical bill. The female is a dull greenish-olive but has black flight feathers and a yellow bill. The oriole finch was formally described in 1843 by the British zoologist Louis Fraser under the binomial name Coccothraustes olivaceus. It is now the only species placed in the genus Linurgus that was introduced by Ludwig Reichenbach in 1850. The exact relationship of this species to other finches is unclear. In their phylogenetic analysis published in 2012, Zuccon and colleagues found that the oriole finch was sister to the genus Serinus. This contrasts with an earlier 2009 analysis by Nguembock and colleagues which found that the oriole finch was sister to the genus Carduelis.

Rare
Under 5% of wildlife watchers report an Oriole Finch sighting in Nyungwe National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 220th most-seen of the 252 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Oriole Finch in Nyungwe National Park on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Oriole Finch sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Oriole Finch sightings, Nyungwe National Park ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Arusha National Park (Tanzania, under 5%), Bwindi Impenetrable National Park (Uganda, under 5%) and Ngorongoro Conservation Area (Tanzania, under 5%).
Same family: Fringillidae
The closest relatives of the Oriole Finch that you can see in Nyungwe National Park (family Fringillidae, Finches, Euphonias, and Allies) are Streaky Seedeater (about 50%), Western Citril (about 20%) and Thick-billed Seedeater (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oriole Finch is recorded against all the birds logged in Nyungwe National Park (7 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.
