Subspecies
No subspecies.
Nesospiza acunhae (Sibley and Monroe 1990, 1993) has been split into Inaccessible Finch (Nesospiza acunhae) (Inaccessible Island) and Nightingale Finch (Nesospiza questi) (Nightingale Island), while subspecies dunnei of Wilkins's Finch (Nesospiza wilkinsi) (Inaccessible Island) has been transferred to Inaccessible Finch (Nesospiza acunhae) following Ryan (2008) who provides compelling phylogenetic evidence for this arrangement and points out the morphological and vocal differences supporting the treatment of paraphyletic forms questi and wilkinsi as species.
Not recognised as a species by BirdLife International.
Considered by some authors to be a subspecies of Inaccessible Finch (Nesospiza acunhae).
