Taxonomy:

Nesospiza wilkinsi

Lowe

, 1923,

Nightingale Island, Tristan da Cunha Group

.

Usually considered conspecific with large-billed race (dunnei) of N. acunhae, but genetic evidence suggests independent evolution on each island. Cytochrome b sequence of present species appears identical to that of N. questi, but the two are highly distinct morphologically and behave as separate species, with separate vocal systems and no evidence of hybridization between them. Monotypic.

Distribution:

Nightingale I, in S Atlantic.
