In accord with AOS-NACC, the monotypic group Broad-billed Hummingbird (Tres Marias Is.) Cynanthus latirostris lawrencei is elevated to species rank as Tres Marias Hummingbird Cynanthus lawrencei (Chesser et al. 2022). Tres Marias Hummingbird is genetically distinct, although levels of genetic differentiation are low (Hernández-Baños et al. 2020), and exhibits plumage differences that comparable to those between other species in the genus (Gómez de Silva 2020, Hernández-Baños et al. 2020)
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.
