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 Arusha National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 261st most-seen of the 373 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.
May, August and October
In those months about 10% of wildlife watchers report an Oriole Finch in Arusha National Park on a given day, against under 5% in June–July, September and November–April, the lowest months.
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.
Yes
Of the 4 parks where we can rate Oriole Finch sightings, Arusha National Park has the highest daily chance: under 5%. Next come 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 Arusha National Park (family Fringillidae, Finches, Euphonias, and Allies) are Southern Citril (about 20%), Streaky Seedeater (about 20%) and Yellow-fronted Canary (about 10%), 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 Arusha National Park (15 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.
