As now restricted this race of White-headed Laughing-Thrush breeds from the Simla and Garhwal Hills, through Nepal into Sikkim.
Hodgson found it breeding in Nepal from the foot-hills, up to 5,000 and 6,000 feet, from April to June, making its nest in small trees. The nest he describes as a rude cup-shaped nest of dry bamboo-leaves, creepers, scales of the turmeric plant etc. and lined with fine roots. Jerdon had the nest brought to him at Darjiling on several occasions, this being “a large mass of roots, moss and grass.” One such was a broad shallow saucer, composed of dead bamboo-leaves bound together with creepers and lined with coarse roots.
Gammie also found it in the Darjiling district but never above 3,500 feet. He sent many nests to Hume, who described them with others :—“ They are all very similar, large, very shallow cups, from 6 to 8 inches in external diameter and from 2.5 to 3.5 in height. Exteriorly all are composed of coarse grass, of bamboo-spathes, with occasionally a few dead leaves intermingled, loosely wound round with creepers or pliant twigs, while interiorly they are composed and lined with black, only moderately fine roots or pliant flower- stems of some flowering tree, or both. Sometimes the exterior coating of grass is not very coarse ; at other times bamboo-spathes exclusively are used, and the nest seems to be completely packed up in these.”
Whymper found this bird breeding at Naini Tal between 4,000 and 5,000 feet, making their nests in small trees. As a rule, however, as Gammie says, “the nests are generally placed in shrubs, within reach of the hand, among low, dense jungle.” In Sikkim and Nepal they breed in April, May and June, most usually in the two former months, but in Naini Tal Whymper took their eggs as late as the 18th July.
The normal number of eggs in a full clutch is four, but they lay up to six and sometimes three only. The eggs are unlike any other Garrulax eggs. They are a pure china white, very hard, very glossy and yet with innumerable tiny pits scattered over their whole surface, whilst in shape they are very broad ovals, sometimes almost spheroidal.
Thirty eggs average 29.2 x 23.5 mm. : maxima 34.3 x 25.3 mm. ; minima 26.1 x 19.7 mm.
