This, the Eastern race of the preceding bird, takes its place in the hills South of the Brahmapootra, the Chin Hills to Yunnan in the East, and South through the Shan States and Siam and the central hills of Burma to Karenni. In the Chin Hills Hopwood and Mackenzie found it breeding at about 5,000 feet, while in the Khasia Hills I found a few nests between 5,000 and 6,200. They seem to keep entirely to thick wet forest with much undergrowth, wandering about in the lower branches of the higher trees and the taller under¬growth. I never saw them in forest composed entirely of Pine but, where this grew, closely mixed with Rhododendron, Oak (Quercus serratifolia) and other trees, a few pairs of these birds were sure to be met with all the year round and, during the breeding season, making their nests, in every case seen by myself, in holes or crevices in gnarled and aged Rhododendron-trees. The nests were all placed just inside small holes, so that the outer part of the nest was flush with the outside of the hole, and all were within reach of my hand when I stood on one of the moss-covered rocks by which they were surrounded.
They were very carefully concealed, blending so well with their green and dripping surroundings that I never succeeded in finding a nest that was not shown me by the bird flitting off it when I was within a few feet of her.
The nests were all just like those of the Western form—very neat little cups of green moss, lined with fur (that of bamboo-rats in those I found), and well finished off with cobwebs and down. Between the fur and the body of the nest there was always an inter¬vening layer of fine roots.
The breeding season in the Chin Hills seems to be from the end of April to the middle of May but, in the Khasia Hills, the few nests we found were from the 29th May to the 17th June.
The full clutch of eggs is three only and they are quite indis¬tinguishable from those of the Western form.
Twenty eggs average 15.8 x 12.0 mm. : maxima 17.2 x 12.1 and 15.6 x 13.0 mm. ; minima 13.1 x 10.8 mm.
