The genus of Puff-backed Bulbul Brachypodius eutilotus, Black-and-white Bulbul Microtarsus melanoleucos, Yellow-wattled Bulbul Microtarsus urostictus, Gray-headed Bulbul Microtarsus priocephalus, Black-headed Bulbul Microtarsus melanocephalos, Andaman Bulbul Microtarsus fuscoflavescens, and Blue-wattled Bulbul Pycnonotus nieuwenhuisiiis changed to Microtarsus Eyton, 1839. They become Microtarsus eutilotus, Microtarsus melanoleucos, Microtarsus urostictus, Microtarsus priocephalus, Microtarsus melanocephalos, Microtarsus fuscoflavescens, and Microtarsus nieuwenhuisii, respectively, based on e.g., Shakya and Sheldon (2017) and a general WGAC preference for broad genera (and thus differing from the treatment in Gill et al. 2023, IOC v.13.2).

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.
