Is every Hume's Yellow-browed Warbler identified correctly? (1 Viewer)

There is a fascinating article on www.birdingisrael.com re the ID of a recent Yellow-browed warbler seen in Israel. This individual was first thought to be Hume's but now appears, after being ringed, to be a YB.

Is the call of Hume's the clincher it was always thought to be, or are some eastern YB's calling and looking more like Hume's???

This reinforces the comment I made on the recent thread about the Cornish "Hume's":

"I don't know if the call has been heard but I have a friend who went to Khazakstan recently, where the local expert guide advised that Yellow-browed and Hume's calls are interchangeable!"

The call of this singleton was heard and was very close to the 'diagnostic' call of Hume's.

some are misidentified perhaps

I've seen Hume's on their breeding gounds and could have messed a few up... if YBrows were also present.

the calls were very confusing and i don't think i heard the typical disyllabic call we think of as diagnostic over here.

I don't think most Ybrows would be misidentified as Hume's but i'm sure it hapens the other way round. They have large ranges, probably not fully mapped and maybe variation is quite high across those ranges, or at least in some areas of them.. and shock, horror, might they be hybridising on occassion?
