A recent Danish language paper (a somewhat popular one) mentioned strong indications that the Eurasian Blackbird should be split into several species, with black plumage in males having appeared independently maybe four times. Is this based on published information or on personal communications to the author? I cannot remember having seen it mentioned before.

Cheers

Turdus maximus Tibetan Blackbird (incl 'buddae') and T simillimus Indian Blackbird (incl nigropileus, 'spencei', bourdilloni, kinnisii) are split from T merula by Rasmussen & Anderton 2005 (Birds of S Asia), Collar 2005 (HBW10) and IOC.
[And R&A 2005 and Collar 2005 comment that T s kinnisii (Sri Lanka Blackbird) is also probably better treated as a distinct species.]

T mandarinus Chinese/Eastern Blackbird (incl intermedius, sowerbyi) is split by R&A 2005 and Robson 2008 (Birds of SE Asia), and noted as a possible species by Collar 2005.

T merula mauritanicus Moroccan Blackbird (incl 'algirus') is suggested as a possible candidate for species status by Small 2006 (More Moroccan birds. Birding World 19(6): 254-262).

Also interesting in this article is the position of Turdus (poliocephalus) niveiceps. I'd also like to know what an alternative generic name for mupinensis would be.
I would not want to draw any conclusions on mandarinus yet.

Hall & Moreau (1970) (An atlas of speciation in African Passerine Birds) considered that T. mupensis, T. philomelos and Psophocichla litsipsirupa formed a superspecies. SO maybe the alternative generic name for mupinensis would be Psophocichla???

Have Fudickar & Parteke overlooked a simpler hypothesis, that migrant Blackbirds might proceed to their wintering grounds in relatively short hops, and so evolutionary pressures for 'long-distance' wings wouldn't exist...?:eek!:

PS. I'd previously missed the fact that Nylander et al 2008 groups intermedius with merula rather than mandarinus, contra Collar 2005 (HBW 10).

HBW Special Volume 2013

Box 5, p. 141: The Common Blackbird (J. Fjeldså)

...some of these populations have different songs, and molecular studies have now confirmed that they are genetically very different and do not even belong near each other in the global phylogeny of Turdus thrushes. The western blackbirds (subspecies merula to intermedius in 10: 645) represent one of the oldest lineages in the Turdus phylogeny. The eastern Chinese mandarinus is another deep branch, most closely related to some African thrushes. The four taxa making up the Indian Blackbird (Turdus simillimus 10: 646), until very recently treated as races of the Common Blackbird, form part of an oriental group with the Grey-winged Blackbird (Turdus boulboul 10 : 646-647) and the Japanese (Turdus cardis 10: 642), Grey-backed (Turdus hortulorum 10: 654-655), Tickell's (Turdus unicolor 10: 654) and Black-breasted Thrushes (Turdus dissimilis (10: 655); and the Tibetan form maximus, already treated as a full species in HBW (10: 646), is related to the White-backed Thrush (Turdus kessleri 10: 649) and various Siberian thrushes (Nylander et al. 2008). ...

TiF update April 18
Following IOC, the Groundscraper Thrush (Psophocichla) has been moved into Turdus.

"Finally, if Nylander et al. (2008) are correct, the Groundscrapper Thrush is more likely sister to the Chinese Thrush than to all of Turdus. In any event, the Groundscrapper Thrush is similar to the Turdus thrushes and I follow IOC in merging Psophocichla into Turdus."

Turdus mandarinus

IOC Update Diary:
Mar 30 Accept Chinese Blackbird

AS 5.2 – Chinese Blackbird – Turdus mandarinus – Chinese Blackbird incl intermedius, sowerbyi recognized by Rasmussen & Anderton 2005, Collar 2005, Robson 2008, Nylander et al 2008, H&M4
www.jboyd.net/Taxo/List26.html#turdidae
Based on Nylander et al. (2008), the Chinese Blackbird, Turdus mandarinus, including the subspecies sowerbyi, but not intermedius, has been split from the Eurasian Blackbird, Turdus merula...
H&M4 also excludes intermedius (citing Nylander et al 2008), contra Collar 2005.

PS. Inclusion of intermedius now tbc ("?")...
