Azores Chaffinch Fringilla moreletti, Madeira Chaffinch F. maderensis, Canary Islands Chaffinch F. canariensis, andAfrican Chaffinch F. spodiogenys are split from Common Chaffinch Fringilla coelebs (Clements 2007:625626)
Details: While all European forms (except the nominate) long treated as conspecific under Fringilla coelebs (Mayr 1968) were originally described as subspecies, all taxa from Macaronesian islands and northern Africa were described as full species. The complex has long been recognized for its marked polytypy and has been well-studied (summarized in Illera et al. 2016), including the considerable vocal disparity which however is of unclear significance for species limits in this complex due to vocal learning (e.g., Lachlan et al. 2013). Illera et al. (2016) proposed considering the taxa of each of the three main Macaronesian island groups as separate species, but this has not been widely followed. Shirihai and Svensson (2018) concluded based on unexpected results in early genetic analyses that all should be considered conspecific. However, the integrative taxonomic analysis of Recuerda et al. (2021) provided a solid framework in terms of morphological and genetic analysis that WGAC, Gill et al. (2023, IOC v.13.2), and Clements et al. (2023) agree strongly supports the recognition of five species, with the African forms being the weakest species candidate, despite the most obvious plumage differences.

Los desacuerdos no deseados ocurren cuando un padre (B) es
disminuido al mover un hijo (E) a otra parte del árbol taxonómico,
resultando en que los IDs existentes del padre sean interpretados
como desacuerdos con los IDs existentes del hijo movido.
Identification
ID 2 del taxón E será un desacuerdo no deseado con la ID 1 del taxón B después del cambio de taxon
Si disminuir a un padre resulta en más de 10 desacuerdos no deseados, debes dividir al padre después de cambiar al hijo para reemplazar las identificaciones existentes de
el padre (B) con identificaciones que no están en desacuerdo.
