(546) Tarsiger chrysaeus chrysaeus Hodgs.
THE NEPAL GOLDEN BUSH-ROBIN.
Tarsiger chrysoeus chrysoeus, Fauna B. I., Birds, 2nd ed. vol. ii, p. 95.
This subspecies of Golden Bush-Robin breeds from Nepal, through Sikkim, to the hills of Assam, both North and South of the Brahma¬pootra. It also occurs, and probably breeds, on the higher hills of Manipur, the Chin and Kachin Hills. It has also been recorded from Yunnan, whence one would have expected Stresemann’s Setschuan race, isabellinus.
In the Himalayas it breeds at considerable elevations. Hodgson says that it breeds in the Central Hills of Nepal but does not say at what height. Osmaston took several nests in Sikkim at about 11,000 to 12,000 feet ; Hickley took one nest above Gangtok at. about 8,000 feet, and this latter is probably about its lowest breeding elevation in the mountains North of the Brahmapootra. In the hills South of Assam it, however, breeds much lower down. In North Cachar I obtained one nest at 6,000 feet and in the Naga Hills it breeds at 7,000 feet, and again, from the Chin Hills I have had a nest and eggs sent me taken at about 7,000 feet.
Hodgson says that “it is shy, solitary and bush-loving. It lays from three to four eggs of a pale verditer blue, regular oval eggs about 0.72 x 0.5, and makes its nest on the ground, in holes of rocks or banks, or at the base of some decaying tree The nest is a compact saucer, composed of moss and moss-roots and lined with sheep’s wool and a few soft feathers. One nest obtained in August measured 4.62 in diameter and 1.37 in height externally ; the cavity measured 2.75 in diameter and 1.12 in depth.”
About Darjiling Osmaston found it breeding from 11,000 feet upwards in thin open forest of Rhododendron-bushes, Silver Fir and Birch. The nests were in every instance built on the ground on steep slopes and fairly well concealed. They were made of moss and grass and lined with hair ; cup-shaped and never domed.
The breeding season, according to Hodgson, is May to August. Osmaston took his nests in the last week of May and in the first two of June ; Hickley found his on the 2nd July and Hodgson, as already recorded, obtained one in August.
The eggs are a pure pale verditer blue, decidedly paler than an Accentor’s eggs and distinctly darker than those of Phoenicurus ochruros or P. schisticeps. In shape they are rather broad ovals but often decidedly pointed at the smaller end. The texture is rather fine and close but, though smooth, practically glossless.
Twenty-one eggs average 19.7 x 14.8 mm. ; maxima 20.3 x 14.8 and 20.2 x 15.2 mm. ; minima 19.0 x 14.2 and 19.4 x 14.1 mm.
