Crestless Fireback is split into two species, based on substantial differences in plumage (del Hoyo and Collar 2014, Eaton et al. 2021). Therefore the monotypic group Crestless Fireback (Malayan) Lophura erythrophthalma erythrophthalma becomes Malayan Crestless Fireback Lophura erythrophthalma; and the monotypic group Crestless Fireback (Bornean) Lophura erythrophthalma pyronota becomes Bornean Crestless Fireback Lophura pyronota.
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.
