The group name 'mountain-tanager' has been applied to species in several different genera (Buthraupis, Tephrophilus, Cnemathraupis, Anisognathus, Dubusia, and Pseudosaltator), and does not form a monophyletic group; therefore change the English name of Buthraupis wetmorei from Masked Mountain-Tanager to Masked Mountain Tanager. Masked Mountain Tanager is more closely related to Grass-green Tanager than it is to Hooded Mountain Tanager Buthraupis montana; change the scientific name from Buthraupis wetmorei to Tephrophilus wetmorei.

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.
