Hello,
I took these two photos at the same place; in Muğla-Göcek (Southwest Turkey) two days ago. There were 3 induviduals, one of them was slightly bigger than other two, and that one’s movements were at least twice as fast. Also it was feeding on higher branches of the tree. Similar disyllabic call was deeper in that bird and it was always chasing the other two (fly after them).
The most noticeable differences are, coloration of lower mandibule (bigger faster bird had almost completely black lower mandibule, but other two had the black color only on the 1/3rd of their lower mandibule. Other part was pinkish yellow), length and color of the wing bars (smaller birds had more prominent and complete wing bars, but faster and bigger bird had less obvious and shorter and discontinuous lesser wing bar), foot and shank colors (smaller birds had paler shanks and claws were creamy yellow, bigger one had blackish foot and shanks) and calls (although they have similar calls, smaller birds had a lower pitched disyllabic call. Bigger one had a characteristic Hume’s Leaf Warbler call). One more thing: smaller ones had slightly yellower eye stripe. By the way size difference was only 8-10 percent.
As a result, I think bigger, faster, black beaked bird was Hume’s Leaf Warbler, and the other two were Yellow-browed (Inonnate) Warbler. I would be glad if you kindly share your opinions. Thanks.
