Given the different morphs that a number of species have, yes it does beg the question as to why one would invoke a new taxa. Consider the variation in Gouldian Finch head colour. I don't believe there has been any taxonomic splitting on the basis of GF plumage.

It is all most peculiar. I don't understand why, if there is an odd Fig-Parrot there (which there could be) it is not just ascribed to an unusual colour variant of Coxen's Fig-Parrot (of the sort that happens occasionally in many species). I don't see the need to suggest a hitherto unnamed sub species or species. That is a long bow to raise. I also don't buy the competitive exclusion principle argument either. There are lots of other sets of sympatric species, such as lorikeets, fruit pigeons etc. The competitive exclusion principle is an idea that is an interesting concept upon which to do biological investigation. It is not a fundamental rule of life.
