Fan-tailed Warbler on Taiwan (1 Viewer)

[Andy Adcock]

The book 'A field guide to the birds of Taiwan' Forestry Bureau, gives volitans as the race here but, that seems not to be recognised by the IOC so which is it?

tinnabulans ?
volitans is a race of Cisticola exilis, not a race of C. juncidis. (And it is recognised by the IOC.)

tinnabulans is what's listed in Clements.

Cheers Jeff,
not got access to my books, that's why I'm making so many requests.

Seventeen up as I write with still fair bit to go

I'm going square eyed, too long looking at excel sheets!

Given that brunniceps apparently occurs both to the north (Japan & Korea) and south (N Philippines) of Taiwan, and is migratory, it seems reasonable to think that this would also occur on Taiwan.
Personally I suspect the taxonomy of this species is not properly resolved in the region (or, in fact, globally). We seem to have two subspecies here in Hong Kong (based on biometrics, plumage and seasonal occurrence patterns) but are only officially in range for tinnabulans from published lists.

I saw that in the Clements data, but didn't know that ssp. was migratory. Good info, John.
