It is a distinctive and critically endangered subspecies, formerly considered a full species, of the Yellow-tufted Honeyeater, that exists in the wild only as a tiny relict population in the Australian state of Victoria, in the Yellingbo Nature Conservation Reserve. It is Victoria’s only endemic bird, and was adopted as one of the state’s faunal emblems in 1971.
