Black-eared Kite (1 Viewer)

Just back from a trip to China. Mackinnon and Phillips give Black-eared Kite as a separate species Milvus lineatus but others seem to have it as a subspecies or race of Milvus migrans.

What is the current position?
 
Milvus lineatus Black-eared Kite is recognised by BirdLife International, Monroe & Sibley 1993, Dutch Birding, China Ornithological Society, and Brazil 2009 (Birds of East Asia);
but not by IOC, Cornell/Clements, Dickinson 2003 (H&M 3), HBW, OBC, AERC, BWP, or BBRC.

That'll be a no then, I'm guessing.

If you accept these data, lineatus is very, very close to M. m. govinda, which is usually kept in M. migrans.

(It's not completely clear from the paper itself, but the bird labelled "BK (India)" in Fig.2, that clusters with the "BK (Japan)" -- this one can only be a lineatus based on range -- corresponds to a sequence identified as govinda in GenBank; the second Indian bird is ID'd as a lineatus in GenBank; the Pakistan bird is said there to be a govinda -- thus the two taxa would not even appear to have reciprocally monophyletic mtDNA... That said, I'd prefer to see more govinda data before to regard this as proven. Here they had only two specimens, both collected in winter, at localities where lineatus is also possible at this time of the year. They don't really make it clear why these could not have been lineatus as well.)

The lineatus/govinda group is then closer to Australian M. m. affinis than the latter is to M. m. migrans -- thus if you want to make a split, either affinis should be a distinct species as well, or it should be included in M. lineatus.

'Eastern Black Kite' – Identifying hybrids and intergrades between Western Black Kite and Black-eared Kite
...
If lineatus is regarded as a species, then the 'intermedius' Eastern Black Kite creates a taxonomic problem, since it represents a huge, self-sustained hybrid population between the two species, thus by some definitions forming a species in its own right, albeit of hybrid origin.
