Taxonomy
The Island Thrush is a member of the cosmopolitan genus Turdus (Linnaeus, 1758), one of the most widely distributed bird genera in the world. The taxonomy of the Island Thrush is complex, and has defied attempts to split the group based on the four suspected morphological types. The subspecies Turdus poliocephalus niveiceps from Taiwan represents the most distinct taxon and may be a separate species. This subspecies lives at the northerly range of the species, and is the only one in which the males and females differ in colour. There are also thought to be at least two further subspecies not yet described scientifically, both from the Indonesian island of Sulawesi.
