Phylogenetic analyses (Qu et al. 2006, Gebauer et al. 2006) provide some support for the recognition of the genus Pyrgilauda Bonaparte, 1850. Pere David’s Snowfinch Montifringilla davidiana now becomes Pyrgilauda davidiana; Rufous-necked Snowfinch Montifringilla ruficollis becomes Pyrgilauda ruficollis; Blanford’s Snowfinch Montifringilla blanfordi becomes Pyrgilauda blanfordi; and Afghan Snowfinch Montifringilla theresae becomes Pyrgilauda theresae; this treatment now aligns with Gill and Wright (2006, IOC v.1.0).

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.
