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 →

Rare
Under 5% of wildlife watchers report an Olive-naped Weaver sighting in Accra on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 104th most-seen of the 162 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February–April, September and December
In those months about 10% of wildlife watchers report an Olive-naped Weaver in Accra on a given day, against under 5% in January, May–August and October–November, the lowest months.
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.
7th of 7
Of the 7 cities where we can rate Olive-naped Weaver sightings, Accra ranks 7th at under 5%. 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 Accra (21 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.
