Smoky Warbler Phylloscopus fuligiventer

Dark sooty leaf warbler with a pale brow stripe and no wingbars. Yellow wash to the underparts tends to be absent in worn birds. Extremely similar in appearance to Dusky Warbler, which averages larger and darker overall, and has a longer, brighter brow stripe. Breeds in scrubby areas above the treeline and moves downhill into shrubby and grassy foothill and lowland areas. Forages low on the ground, often around rocks or water. Song is a repetitive series of liquid notes. Calls are dry, hard “chuck” or “tick” notes.
