Hume's Leaf Warbler inhabits the mountain forests of Central Asia up to the tree line. It closely resembles the Yellow-browed Warbler. Its migration routes to the species' south Asian wintering sites are, however, much shorter than those of its twin. In Europe, Hume's Leaf Warbler is spotted more rarely than the Yellow-browed Warbler, occurring mainly in late autumn and winter. It can be distinguished from the Yellow-browed Warbler by its duller plumage, darker beak and legs, and especially its call.
