Taxonomie

The species was formally described in 1805 by the French ornithologist Louis Pierre Vieillot, who named it Malimbus nigricollis. The description was based on a specimen that had been collected near Malimbe, now Malembo, in the Cabinda Province of Angola. The species epithet nigricollis combines the Latin words Latin words, niger meaning "black" and collis meaning "necked".<p>There are two subspecies recognized:<p>The black-necked weaver was formerly considered to be conspecific with the olive-naped weaver. The two species differ in plumage and in the colour of the iris. A molecular study published in 2019 found that the two species are genetically very similar.
