Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Ploceus. This

Review identifications of Ploceus nigricollis 13825
The monotypic group Black-necked Weaver (Olive-backed) Ploceus nigricollis brachypterus is recognized as a separate species, Olive-naped Weaver Ploceus brachypterus. The plumage and iris color of Olive-backed Weaver are strikingly different from those of Black-necked Weaver (del Hoyo and Collar 2016). The two apparently hybridize where their ranges abut, a contact zone that has not been studied in detail, but any hybrid zone appears to be quite narrow in comparison to the widespread distributions of each of the two species.
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
