Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Tolmomyias. This
happens when we can't automatically assign an identification to one of the
output taxa.
Review identifications of Tolmomyias assimilis 16546
The monotypic group Yellow-margined Flycatcher (Yellow-winged) Tolmomyias assimilis flavotectus is recognized as a separate species, Yellow-winged Flycatcher Tolmomyias flavotectus; all remaining subspecies remain in Yellow-margined Flycatcher. Yellow-winged Flycatcher is basal to the rest of Tolmomyias, so retaining flavotectus in Yellow-margined Flycatcher would lead to a highly paraphyletic species (Harvey et al. 2020); flavotectus also is the most distinctive member of the Yellow-margined Flycatcher group vocally, although variation in vocalizations across this complex suggests that further splits may be warranted (Boesman 2016f).
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.
