Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Myiopagis. This
happens when we can't automatically assign an identification to one of the
output taxa.
Review identifications of Myiopagis caniceps 16903
Genetic evidence indicates that Gray Elaenia is paraphyletic with respect to Foothill Elaenia Myiopagis olallai (Rheindt et al. 2009b, Cuervo et al, 2014); and there also is significant variation in vocalizations across Gray Elaenia (Cuervo et al. 2014, Boesman 2016). Therefore Gray Elaenia is split into three species: the polytypic group Gray Elaenia (Choco) Myiopagis caniceps parambae/absita becomes Choco Elaenia Myiopagis parambae, with subspecies parambae and absita; the monotypic group Gray Elaenia (Gray) Myiopagis caniceps cinerea becomes Amazonian Elaenia Myiopagis cinerea; and the monotypic group Gray Elaenia (Gray-headed) Myiopagis caniceps caniceps becomes Gray-headed Elaenia Myiopagis caniceps.
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.
