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???
