Eurasian Reed Warbler and African Reed Warbler have very similar morphologies and songs, and do not differ in habitat choice (Dowset-Lemaire and Dowsett 1987, Kennerly and Pearson 2010), and genetic divergence between the two species also is shallow (Olsson et al. 2016). Therefore African Reed Warbler is lumped with Eurasian Reed Warbler. Change the English name of the combined species to Common Reed Warbler. African Reed Warbler continues to be recognized as a new polytypic group, Common Reed Warbler (African) Acrocephalus scirpaceus [baeticatus Group], with subspecies ambiguus, guiersi, cinnamomeus, hallae, suahelicus, and baeticatus.
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.
