Rwenzori Nightjar does not merit recognition as a species, based on vocal similarities (Dowsett and Dowsett-Lemaire 1993) to Abyssinian Nightjar, and the absence of significant plumage or morphometric differences between the two (Louette 1990, Jackson 2014). The combined species becomes known as Montane Nightjar Caprimulgus poliocephalus.
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.
