 due to very incomplete lineage sorting.

The Yellow-billed Kite is apparently a good species, as indicated by mtDNA phylogeny, biogeography, and morphology. The Black-eared Kite is somewhat distinct morphologically, but is better considered a well-marked parapatric subspecies. The status of the Cape Verde Kite is in doubt; while not a completely monophyletic lineage according to mtDNA data, it is still best regarded as a distinct species. Whatever its status, this population is extinct.
