As expected (see my post from June below):
Quote from http://jboyd.net/Taxo/List18.html ;(just posted by Paul Taylor in a
post discussing the taxonomy of Crested Bellbird): "The
genus Gymnorhina (Australian Magpie) has been merged
with Cracticus and Strepera has been reordered based on Kearns et al. (2013).
The Black Butcherbird has been split into New Guinea
Black-Butcherbird, Cracticus quoyi, and Australian Black-Butcherbird, Cracticus
spaldingi. Kearns et al. (2011) found substantial genetic distance between
these allopatric groups of taxa. However, Kearns et al. (2013) found little
genetic distance and relationships that did not match the allopatric species in
the Gray (or white-throated) Butcherbird group. Recognition of the
Silver-backed Butcherbird, Cracticus argenteus, has always been controversial
(e.g., IOC does not recognize it). The Black-backed Butcherbird, Cracticus
mentalis, has been considered separate. In fact, some argenteus grouped
with mentalis and some grouped
with torquatus. All were genetically close, with a common ancestor probably
about 200,000 years ago. Because of this I've lumped them with the Gray
Butcherbird, Cracticus torquatus."

Forgot one thing. There is another take-home message:
Either split Black BB into Australian BBB and New Guinea BBB or leave them
lumped. In the latter case consequently, all three 'white-throated BBs' (Grey,
Black-backed and Silver-backed) should be lumped, too, as these three seem to
be more closely related to each other than the two populations of BBB to each
other.

Philip,
No, it's not that simple. Kearns et al. 2013 clearly shows that Australian
Magpie is more closely related to Black Butcherbird than Black Butcherbird to
all other butcherbirds. So, following your 'opinion idea', there are two
options: (1) AM is a butcherbird and all butcherbirds including AM are lumped
into one genus [as proposed by Kearns et al. 2013 and earlier by Christidis &
Boles 2008] or (2) Black Butcherbird is a 'magpie' and consequently lumped with
it in Gymnorhina and the remaining butcherbirds in Cracticus.
Also very interesting is that some Silver-backed BBs appeared to be closely
related
to Grey BB but others to Black-backed BB. It looks like that another
manuscript discussing this more into detail is in preparation.
Cheers,
Nikolas

It is a formality of moving from being in the same family to being in the
same genus. As all taxa are really expressions of opinion as to where the
dividing line lies, it is not such a big change. Even casually, the
similarity is suggestive.

Hi John,
Interesting, though this was surely this has been on the cards for a while
before this
study. It was already listed as Cracticus tibicen by Christidis
& Boles 2008, though I note IOC currently still has it in Gymnorhina (see
http://www.worldbirdnames.org/n-batises.html). Not too surprising given
quite a few similarities in morphology and voice. Ron Johnstone from the WA
museum also mentioned that there are records of Pied Butcherbirds
hybridising with Australian Magpie in central Aus.
Cheers,
John
