The Yellow-bellied Tit is a small tit that forms flocks in mountain forests. Males have black-and-white heads and yellow underparts; females are duller greenish grey.
It is about 9-11 cm long. Males have a black head, white cheeks and nape, and yellow underparts. Females have an olive-grey head, grey-green upperparts, and pale yellow-green underparts.
It forages in flocks in mountain forests, but is seen alone or in pairs during breeding. It mainly eats insects and also takes pine seeds, other nuts, and grass seeds in winter.
