A smart little Mountain Leaf Warbler (Phylloscopus trivirgatus parvirostris) with striking head markings. I wondered if this was a first year bird. Although the markings all look like an adult, including the bare parts, note the clear white patch at the belly (also seen in other views); Wells (2007) states that juveniles have a white belly.
However, I looked at all my older images and the belly is whitish even in adult birds that are nesting. Perhaps a feature not often noted.
Note that both the supercilium and median stripe broaden/widen as they progress posteriorly (Wells 2007).
