In accord with AOS-NACC (Chesser et al. 2021), the nomenclature of cormorants and shags, and the sequence of genera and species, are revised, following Kennedy and Spencer (2014) and Kennedy et al. (2019). The new sequence of genera is Poikilocarbo, Urile, Phalacrocorax, Gulosus, Nannopterum, and Leucocarbo. Change the scientific name of Guanay Cormorant from Phalacrocorax bougainvillii to Leucocarbo bougainvillii.

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.
