Clearly very closely related to D. spilorrhoa, D. subflavescens and D. luctuosa; species limits in this group are unclear, and all four sometimes considered conspecific (a position which the scoring system used herein would seem likely to endorse), while other authors recognize up to five species; further study of genetic, morphological and acoustic details required in order to clarify the situation. There is evidence that nominate bicolor and proposed taxon “melanura“ (sometimes classified as a race of bicolor) occur sympatrically on Kai, Ambon, Bacan, Halmahera and perhaps other islands, which has been interpreted as evidence that the forms are reproductively isolated full species or, conversely, that they are mere colour morphs; latter view followed here, particularly as differences are minor and appear to be individually variable, with many intermediate forms occurring. In past, birds of Moluccas sometimes separated as race siebersi. Monotypic.
