The chestnut-and-black weaver (Ploceus castaneofuscus) is a species of bird in the family Ploceidae. It is found in West Africa from Sierra Leone to southern Nigeria. The chestnut-and-black weaver was formerly treated as a subspecies of Vieillot's black weaver (Ploceus nigerrimus). The species were split based on the striking differences in the colour of the plumage. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Chestnut-and-black Weaver is recorded against all the birds logged in Freetown (8 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.
