Hab.~ The Eastern Himalayas from Bhootan to Nepaul. Occurs also in 

 Sikkim, Darjeeling, the Khasia hills, and in British Burmah, east of Tonghoo. 

 Hume, quoting Hodgson's notes and figures, says that it breeds in Sikkim 

 and Nepaul, up to an elvation of 6,000 or 7,000 feet. The nest is placed at a 

 height of 6 to i O feet from the ground, between some leafy, horizontal fork, 

 between which it is suspended. It is composed of moss and moss roots and 

 vegetable fibres, beautifully and compactly woven into a shallow cup, some 

 4 inches in diameter, with a cavity some 4 5 inches in depth. Interiorly 

 the nest is lined with hair-like fibres and moss roots and exteriorly adorned 

 with lichen. The eggs are two or three in number, very regular ovals, 

 about 077 in length x 0*49 in width ; ground colour a delicate pinky lilac, 

 speckled and spotted with violet or violet purple, the markings being more 

 numerous towards the large end, where they have a tendency to form a 

 mottled zone.
