Message: <blockquote data-quote="Shi Jin" data-source="post: 1754834" data-attributes="member: 74596">Thanks for posting Zou's paper.While reading it I realised that I have seen all 4 species of "grey-cheeked" fulvetta in China (food for thought as I've only been counting one species).I can't understand much of the science, but I was intrigued to see that they sourced their "fratercula" birds from the Tengchong area of western Yunnan.  As has been pointed out already on this thread, Fratercula has now been split by the IOC, and takes the name Yunnan Fulvetta (presumably on the basis of Zou's study).I've just got back from Yunnan and, until I read Zou's paper, was convinced that I had seen ssp yunnanensis in the Gaoligongshan, only 20km from Tengchong.  The ("northwestern") Yunnan population of yunnanensis is thought by Zou to be related to the central clade of davidi/schaefferi via Sichuan, and is now treated as a ssp of what I would prefer to call Pere David's Fulvetta.It would be remarkable if these two newly-described species lived side by side; the obvious explanation is that I misidentified the many flocks of birds I saw near Tengchong ;-)</blockquote>
