Mountain Leaf Warbler Phylloscopus trivirgatus

Small leaf warbler of montane rainforests throughout Sundaland. Strongly contrasting head pattern with black eye-stripe, pale eyebrow and black stripes either side of the central pale crown stripe. Note the lack of wing bar. In most areas, birds are yellowish green above and brighter yellow below; birds on Mount Kinabalu are gray-green above and off-white below. Forages actively in upper levels of forest, often in mixed flocks. Compare with migratory leaf warblers. Song is a rolling series of high-pitched warbling notes.
