Vieillot's black weaver (Ploceus nigerrimus) is a species of bird in the family Ploceidae. It is found in southern Nigeria to Uganda, west Kenya, Angola and the Democratic Republic of the Congo. The common name is after the French ornithologist Louis Pierre Vieillot.
This species was formerly considered to be conspecific with chestnut-and-black weaver (Ploceus castaneofuscus). The species were split based on the striking differences in the colour of the plumage. Vieillot's black weaver - Species text in Weaver Watch. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Vieillot's Weaver is recorded against all the birds logged in Brazzaville (9 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.
