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 →

With luck
About 10% of wildlife watchers report an Olive-naped Weaver sighting in Kumasi on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 26 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report an Olive-naped Weaver in Kumasi on a given day, against under 5% in April–May and October–November, the lowest months. January–February and June–September have too few records to rate.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Olive-naped Weaver sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 7
Of the 7 cities where we can rate Olive-naped Weaver sightings, Kumasi ranks 5th at about 10%. The best odds are in Abuja (Nigeria, about 30%), Serrekunda (Gambia, about 20%) and Freetown (Sierra Leone, about 10%).
GBIF citizen-science records
It is estimated from how often the Olive-naped Weaver is recorded against all the birds logged in Kumasi (7 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.
