分类信息
The Taiwan whistling thrush was collected by Robert Swinhoe and described as Myiophoneus insularis by John Gould in 1862. Swinhoe called it the "Formosan cavern-bird" because it inhabits the dark, forested ravines in the mountains. It was formerly considered a subspecies of the Malabar whistling thrush (Myophonus horsfieldii). The species is monotypic.
