THE SIMLA GREEN SHRIKE-BABBLER.
Pteruthius xanthochloris occidentalis Harington, Bull. B. O. C, xxxiii, p. 82 (1913) (Dehra Dun).
Vernacular names. None recorded.
Description.— Male. Differs from the last in having the crown and nape ash-grey instead of blackish and the whole plumage is somewhat paler and less vivid. The female differs in having the head greenish with a wash of grey.
Colours of soft parts and Measurements as in the last.
Distribution. N.W. Himalayas from the Sutlej Valley to Garhwal and, possibly, W. Nepal.
Nidification. Nests taken by Osmaston and Rattray are described as deep cradles of root-fibres and lichen, bound together with cobwebs, lined with the finest black roots and rhizomorph of a fungus and attached to small forks in the outer branches of spruce or deodar. They apparently breed from April to July at elevations between 5,000 and 9,000 feet and lay two to four eggs. These are miniatures of those of P. erythropterus and ten eggs average about 19.4 x 14.6 mm.
Habits. Practically nothing recorded. It keeps much to heavy tree-forest in pairs or solitary, frequenting the higher branches, where it attracts no attention either by voice or its quiet movements.
