Taxonomic Split 57606 (Guardado el 17/01/2020)

This is a retroactive split - Vireo chivi was added when it should have been split off from Vireo olivaceus. We are now splitting Vireo olivaceus after the fact to sort out existing identifications of Vireo olivaceus that now apply to Vireo chivi

Why are we developing a new taxon for Vireo olivaceus?

Anotado por birdwhisperer hace casi 5 años

My understanding is that when taxa are split, it is better to create two new taxa. The new olivaceus sensu strictu is a different taxon concept to the old broader taxon, with a different range and different component subspecies.

@rjq this is another situation (similar to where Vireo olivaceus migrates pretty much down to the southern limit of Vireo chivi. Do we need a retroactive split to deal with identifications of Vireo olivaceus 17366 that should now be considered Vireo chivi or can this be sorted out in the IDing process - doesn't look like there's too many observations of Vireo olivaceus 17366 in the overalp area

I think this needs the split, there are 146 South American obs of olivaceus which will need confirming (or leaving as the genus). In general, observers seem more willing to make changes when a split has been made, than when a new ID is made with a comment about a split
