The olive-naped weaver (Ploceus brachypterus) is a bird species in the family Ploceidae. It is found in West Africa from Senegal and Gambia to Cameroon. The olive-naped weaver was formally described and illustrated in 1837 by the English naturalist William Swainson. He did not specify the origin of his specimens but they probably came from Senegal. He placed the species in the genus Ploceus and coined the binomial name Ploceus brachypterus. The specific epithet is from Ancient Greek brakhupteros meaning "short-winged".
The olive-naped weaver was formerly considered to be a subspecies of the black-necked weaver (Ploceus nigricollis). The two species differ in plumage and in the colour of the iris, but a molecular study published in 2019 found that they are genetically very similar. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Olive-naped Weaver is recorded against all the birds logged in Freetown (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.
