The Willow Warbler (Phylloscopus trochilus) is a small, delicate migratory songbird that passes through Lebanon during spring and autumn migration. It prefers woodlands, gardens, orchards, and vegetated valleys, where it moves actively among foliage in search of insects. Recognized by its pale greenish upperparts, whitish underparts with a soft yellow wash, and a faint eyebrow stripe, it can be difficult to distinguish from similar leaf warblers. It feeds mainly on insects and larvae, occasionally taking small berries. Despite its subtle appearance, its sweet, descending song is one of the most recognizable sounds of migration across its range.
