Three Dunnocks. (1 Viewer)

Apologies if this has a thread already, but it’s news to me. (And a tick eventually)

Anyone know if IOC are looking at this? It’s not on their website.

There is a thread about this split somewhere on the forum

Which is here:

Prunellidae

Lucky me. I add two new species to my life list.

Don't count your Dunnocks before they hatch! The IOC seem to reject as many proposed splits as accept them and as they haven't acted on this one yet doesn't bode well.

Ian

PS I'd get two ticks out of it too.

And the most recent update diary suggests lumping Arabian and Radde's Accentor (spurred by recent discussion here?)

The basis of the lump probably lies with the difference in suggested divergence times in Drovetski et al 2013 and Liu et al 2017, the former being 0.19MYa and the latter 0.7MYA. Kirwan et al 2021 challenged the latter conclusion, suggesting that the genetic interpretation of one aspect of the methodology was not as robust as it had seemed, techniques having improved in the interim. Kirwan et al 2021 also noted that the samples of Radde's Accentor in both papers came from a narrow geographical basis.
