The Pacific Robin (Petroica multicolor), is a red-breasted Australasian robin in the passerine bird genus Petroica found on Norfolk Island, Melanesia and Polynesia. It is similar in plumage to the Scarlet Robin of Australia, and until recently the two were considered conspecific until split in 1999 by Schodde and Mason. 14 subspecies of Pacific Robin are currently recognised, and these subspecies display considerable variation in plumage, foraging preferences and habitat.
