In accord with AOS-NACC (Chesser et al. 2022), Lesser Kiskadee is removed from Pitangus and is placed in the genus Philohydor Lanyon 1984, based on genetic evidence that Lesser Kiskadee is not the sister species to Greater Kiskadee Pitangus sulphuratus, and indeed the two species are not at all closely related (Harvey et al. 2020); Lesser Kiskadee also differs markedly from Greater Kiskadee in cranial and syringeal morphology and in nest structure (Lanyon 1984).
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.
