Hmm... How it's going? Former Sylvia cantillans moltonii is now Curruca subalpina, Moltoni's Warbler? And Sylvia cantillans cantillans is now Curruca cantillans, Eastern Subalpine Warbler? I'm little bit confuse... :brains:
There's a summary in a post on the taxonomy forum. Basically there are now 3 species and thanks to the wonderful rules of taxonomy the species name "subalpina" now applies to the only one of the 3 that isn't called "subalpine" in English.
IOC made the split on 6 May, see their updates diary entry.
Doesn't affect me as I've never seen any of them...
