Mark and I ended up having a good look at three wing-barred phylloscs in Mamzar Park yesterday. Birds 1 and 3 were pretty straight forward and as well as looking the part, they both were very vocal and gave typical Hume's calls. Bird 3 even gave a short burst of song, the distinctive single, descending, high-pitched note.
Bird 2, however, was a different story. It was clearly Mark's bright bird from last week but seemed to be more ambiguous, giving range of calls. At first, it sounded (to my ears) like a classic YBW but then would call like a Hume's. To look at, it seems to be showing a few pro-YBW features like bare-parts colour and a strong second wing-bar, but could it just be a very bright Hume's?
