Mosquitero del Emei Phylloscopus emeiensis

Brightly-marked medium-sized leaf warbler. Bright yellow-green above with two long yellow wingbars, white underparts, a broad yellowish eyebrow, and a pale crown stripe. Bill is long and bicolored: gray above, orange below. Most similar in appearance to “Blyth’s-type” warblers, but crown stripe narrower and less diffuse. “White-tailed-type” warblers such as Davison’s can also be similar, but Emei averages duller green above with less intense yellow areas. Breeding range highly restricted: only known from a handful of sites in central China, where it is found in mid- to high-altitude hill and montane deciduous broadleaveded or mixed forests. Wintering range essentially unknown, but has turned up in Myanmar. Song is a medium-length resonant trill; calls include “chup” and “chew”.
