Nidification. Breeds in Sikkim in May and June and occasionally as early as April at between 6,000 and 8,000 feet, making a bulky, cup-shaped nest of twigs, bamboo leaves, grass, roots and stems of plants, lined with finer roots and fern-rachides and placed in small trees or high bushes at any height between 5 and 15 feet. The eggs, two or three in number, are pale blue-green, very like those of Garrulax moniliger, but the texture is smoother and closer though not nearly so hard or glossy as those of the ruficollis group. Fifteen eggs average 30.5 x 22.1 mm.
Habits. Similar to those of the rest of the genus. This bird, however, is one of high altitudes, being found principally between 3,000 and 5,000 feet, and ascending up to 6,000 feet in summer and descending to about 2,000 in winter.
