It undertakes one of the longest migrations of any Old World warbler, wintering in Southeast Asia and the Philippines. Its pale supercilium and olive-green plumage are typical of Phylloscopus warblers in forested habitats.
Alström's Warbler
Alström's Warbler is a tiny leaf warbler weighing just 8 g with a short 11.1 cm wingspan, found in dense forest undergrowth. It gleans insects from foliage with quick, restless movements typical of its family Phylloscopidae.
