Pale-billed Firefinch is lumped into African Firefinch. Differences between landanae and other subspecies of African Firefinch are so slight (Payne 2004) that we do not even recognize landanae as a monotypic group. Insert landanae immediately following subspecies haematocephala.
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.
