Dull brownish leaf warbler. Brown above with brownish-yellow underparts. Extremely similar in appearance to Radde’s Warbler, but Yellow-streaked has a more contrastingly pale brow stripe, finer bill, and fine yellow streaks on the breast. The breast streaks themselves are often not visible, instead appearing as a faint yellow wash from a distance. Dusky Warbler is somewhat similar but is much browner overall with a darker brow stripe and less contrast between upper- and underparts. Breeds in subalpine shrubbery and descends into foothills to winter in similar habitat. Song is a series of cascading tinkling, buzzy notes. Gives metallic “tinks”.
