Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Ceyx. This
happens when we can't automatically assign an identification to one of the
output taxa.
Review identifications of Ceyx erithaca 2623
This is a retroactive split - Ceyx rufidorsa was added when it should have been split off from Ceyx erithaca. We are now splitting Ceyx erithaca after the fact to sort out existing identifications of Ceyx erithaca that now apply to Ceyx rufidorsa

@rjq and @maxkirsch - can you advise here. Is a retroactive split necessary here? I see that the range of Ceyx erithaca 2623 is wrong. But we can update the range (e.g. with the one on Ceyx erithaca 850880)
but a retroactive split would only be necessary to deal with obs ID'd as Ceyx erithaca 2623 what should have been split off as Ceyx rufidorsa 72646
Clements says Ceyx erithaca is "partially migratory, wintering to the southern Thai-Malay Peninsula and Sumatra" - so are those obs from there obs that should be split off as Ceyx rufidorsa, or are they just migratory Ceyx erithaca?
I guess I'm asking whether we need to split here or whether we can just let IDers sort out confusion between sympatric Ceyx erithaca and Ceyx rufidorsa south of the Isthmus of Kra?
Still necessary, for similar reasons to the vireo. Please note that range for 850880 is wrong as excludes wintering range, but atlas is correct (erithaca also reaches Borneo, not stated in Clements). Have added an atlas for rufidorsa.
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.
