Yellow-vented Warbler Phylloscopus cantator is uncommon resident from Nepal across India and Bangladesh to Thailand and Laos. Two subspecies, both with records in China: nominate reported in Nyingchi Prefecture in Tibet and around Ruili in western Yunnan and pernotus in Xishuangbanna, Yunnan. HABITAT Breeds and winters mainly in evergreen deciduous forests between 300-2000 m (980-6,560 ft.). ID & COMPARISON Distinguished from Sulphur-breasted Warbler P. ricketti by white lower breast and belly and sometimes by less strongly contrasting black-and-yellow crown pattern. Distinctly offset white belly contrasting with yellow vent and throat also distinguishes Yellow-vented Warbler from yellowish Blyth’s Leaf Warbler P. reguloides, Hartert’s Leaf Warbler P. goodsoni, Kloss’s Leaf Warbler P. ogilviegranti, and Davison’s Leaf Warbler P. davisoni; all of which have more or less white in tail. VOICE Short, high-pitched, six-note song: see-see sa-chew sa-chew, emphasis on last note. Double-note call also has emphasis on last syllable. — Craig Brelsford
