Blue-throated Piping-Guan is split into two species, based on differences in plumage and in the color and shape of the wattle, and because there is only limited documentation of hybridization between them (Vaurie 1967). Therefore the monotypic group Blue-throated Piping-Guan (Blue-throated) Pipile cumanensis cumanensis becomes Blue-throated Piping-Guan Pipile cumanensis; and the monotypic group Blue-throated Piping-Guan (White-throated) Pipile cumanensis grayi becomes White-throated Piping-Guan Pipile grayi.

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.
