So, very close to the taxonomic treatment adopted in Ferguson-Lees & Christie 2001 (Raptors of the World).

Annoying that the diagram is not quite legible :C

But Fig 1 and Fig 2 are (using Laurent's crafty .sml > .jpg trick).

 

[Nutcracker]

Thanks! Can't even see thumbnails of those two figures in the abstract, how does the trick work?

Guess there's going to be some major dismembering of Accipiter soon, into at least 5 genera.

Eastern Marsh Harrier now monotypic.

Northern Harrier sister taxon to Cinereous Harrier, these two being a sister group to Hen Harrier. Neat.

Right-click on figure, and 'Copy Image Location'. Then paste link into browser, and replace extension '.sml' (= small) with '.jpg'.

Thanks, though the figure already has a jpg extension, so it doesn't work:

Nobody has discussed the paraphyly of the genus Accipiter revealed by this work. Was this an unexpected finding or has this been known about before?

Also isn't it surprising that Montague's is more closely related to the marsh harrier clade rather than the steppe harrier clade?

Ian, see discussion of this paper (amongst others) here.

New to me though is how way distant Crested Goshawk (A. trivirgatus) is from the others, even outside aquiline eagles!

Hope this version is legible enough

Thanks! How did you manage to magnify it?

No wizardry involved - just a cropped screenshot of the diagram in the paper pdf

Support is certainly better now, but see [this].

Interesting paper! I wonder if there will be another proposal to the AOU to split the two species. The data in this paper certainly argue for it and they do address some of the concerns from the last proposal, though the genetic sample sizes are still fairly small. For anyone wanting to read the comments from the 2015 harrier proposal, they are here:

But odd that they didn't include any Circus cinereus data?
