Each of the two monotypic groups is recognized as a separate species, based on based on differences in size and in female plumage, and on differences in song (Alström, unpublished). Therefore the group Vivid Niltava (Chinese) Niltava vivida oatesi becomes Chinese Vivid Niltava Niltava oatesi, and the group Vivid Niltava (Taiwan) Niltava vivida vivida becomes Taiwan Vivid Niltava Niltava vivida. Revise the range of Chinese Vivid Niltava from "SE Tibet to sw China, ne India, Myanmar and n Vietnam" to "breeds in southern China (from southeastern Xizang east to southwestern Sichuan and Yunnan) and probably adjacent northern Myanmar; winters from northeastern India (where possibly resident), Myanmar, and northern Thailand".
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.
