Hi all,
I now retract part of what I said the other day.

I got Alstrom and Mild's excellent volume on the Pipits and Wagtails =
yesterday, and after studying their account, I now think that one 
should =
recognise two species in the Yellow  Wagtail complex: M. flava Western =
Yellow Wagtail and M.tschutschensis Eastern Yellow Wagtail, as the AOU =
has done.

The nuclear DNA data from Alstrom & Mild on page 265 shows that =
tschutschensis, macronyx and taivana group as sister species to each =
other in a branch with 100% bootstrap support.  That branch is a =
sister-clade to a branch containing M. cinerea cinerea, and that =
combination of these two branches has 92% bootstrap support.  The rest =
of M. flava is relatively distantly related to the M.tschutschensis =
complex.

The mtDNA data in Pavlova et al.2003 in Auk 129 (3) 744-758, as well as 
=
the mtDNA data in Alstrom & Mild p.264 does not agree with all aspects =
of the nuclear intron data.  But all data sets support the distinctness 
=
of  the Eastern tschutschensis complex from the Western flava complex.

So if you have seen Yellow Wagtail in OZ, the species is M. =
tschutschensis, Eastern Yellow Wagtail.  By far the most common is =
"simillima" which has been lumped into nomnate tschutschensis; =
M.t.taivana is considerably less common; and M.t.macronyx also a rare =
vagrant.

And I don't think Christidis and Boles could come to any other =
conclusion!
John Penhallurick
