Mésange montagnarde Parus monticolus

Colorful small songbird of foothill and montane forests (up to 2800 m). Similar to Japanese Tit in appearance but with a bright yellow belly, greenish back, and two narrow white wingbars rather than one broad one. Forages at middle and upper levels in forests, often in pairs or as part of mixed-species flocks. Song a series of 3-4 whistles. Calls infrequently, a gruff “deedeedee.”
