Each of the two polytypic groups is recognized as a separate species, based on differences in size, wing-tip structure and plumage (especially tail pattern), following (Schodde and Mason 1999). The group Australasian Pipit (Australian) Anthus novaeseelandiae [australis Group], with subspecies exiguus, rogersi, bilbali, australis, and bistriatus, becomes Australian Pipit Anthus australis; and the polytypic group New Zealand Pipit Anthus novaeseelandiae, with subspecies novaeseelandiae, chathamensis, aucklandicus, and steindachneri, becomes New Zealand Pipit Anthus novaeseelandiae.
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.
