The thrush is thought to have evolved from an ancestor in the genus Turdus from South America, and resembles an immature Austral Thrush, but its adaptations to life on a small island group, including an unusual brush-tipped tongue modified for extracting the contents of eggs, have been used as reasons to warrant its separation into the monotypic genus Nesocichla.
