Nidification. This little Yuhina breeds from 4,000 feet upwards throughout its range in the months of May, June and July. It makes a beautiful cradle-shaped nest of moss roots, a tiny scrap or two of moss and a lining of the finest grass stems. It is placed either in amongst the pendent roots of overhanging banks or in amongst the lichen on the lower side of dead branches, in nearly all cases well concealed and difficult to find. They measure only about 80 to 90 mm. in diameter by about 65 mm. in depth. The eggs number three or four and are pale sea-green in colour, lightly marked all over with freckles of reddish, and they measure about 16.5 x 12.2 mm.

Habits. This little Yuhina keeps much to the higher branches of medium-sized and high trees, hunting about tor insects in the manner of Titmouses, as often hanging head downwards from the under side as scurrying along the upper, or even clinging, Tree-creeper like, to the bark of the trunk itself. They collect in flocks of some size and keep up a constant " chip, chip " the whole time, occasionally breaking out into a louder, shriller call.
