iNaturalist follows Clements - not the Checklist of the Birds of New Zealand - for bird taxonomy, and Clements considers the North and South Island Robins to be conspecific.
Clements, J. F., T. S. Schulenberg, M. J. Iliff, D. Roberson, T. A. Fredericks, B. L. Sullivan, and C. L. Wood. 2016. The eBird/Clements checklist of birds of the world: v2016. Downloaded from http://www.birds.cornell.edu/clementschecklist/download/ (Vínculo)
(Note - due to an error in the taxon change a few months ago that split these taxa [going against Clements], the original iNaturalist taxon concepts for New Zealand Robin and South Island Robin were synonymized, so all New Zealand Robin IDs from the North Island became South Island Robin; if you IDd any robins from the North Island over 5 months ago or so, please check to make sure your IDs are of the right taxon)
Los desacuerdos no intencionados ocurren cuando un grupo padre (B) se adelgaza al cambiar un grupo hijo (E) a otra parte del árbol taxonómico, provocando que las Identificaciones existentes del grupo padre sean interpretados como desacuerdos con las Identificaciones existentes del grupo hijo cambiado.
Identification
La ID 2 del taxón E será un desacuerdo no intencionado con la ID 1 del taxón B después del intercambio de ancestros
Si el adelgazamiento del grupo padre provoca más de 10 desacuerdos no intencionados, deberías dividir el grupo padre después de intercambiar el grupo hijo para substituir las identificaciones existentes del grupo padre (B) con identificaciones con las que no esté en desacuerdo,
