Migrant Willow Warblers Phylloscopus trochilus observed foraging preferentially in low desert shrubs much in the manner of Asian Desert Warblers Sylvia nana, Lulu island, Abu Dhabi

摘要

The Willow Warbler Phylloscopus trochilus is a common spring migrant through the United Arab Emirates (Pedersen & Aspinall 2010) and occurs predominately in areas with native though often planted trees, especially Ghaf Prosopis cineraria and to a lesser extent Sidr Zizyphus spina-christi. In these it feeds arboreally, in typical Phylloscopus manner. This generally involves active gleaning and sallying through the canopy with birds often concentrating on the outermost branches.
