Hartert gives the breeding range of this bird as Gobi, Kansu in East Tibet, Chuanche and Ditschu and Kuku-nor. Two skins sent me with nests and eggs from Yatung, Gyantse and Rhamtso both appear to me to be referable to this form rather than to nipalensis, as I should have expected. The skins are so fragmentary, so dirty and stained, that one cannot judge the depth of colour, but the broad white edgings to the chestnut flank-feathers forbid. one placing it with nipalensis. If my identification of these fragments is correct, the breeding range evidently extends into South and South-West Tibet.
It appears to be restricted to elevations above 12,000 feet, and pro¬bably breeds at least up to 15,000, where it haunts open plains with scattered scrub-jungle of roses, brambles and small thorny bushes, and with rocks, boulders and smaller stones scattered everywhere. Of the three nests sent me two were built low down in a matted tangle of rose-briars sheltered by boundary walls, whilst the third was in the open, built within a few inches of the ground in a low, very dense, thorny bush. In two cases, once from Gyantse and once from Rhamtso, skins were sent with the eggs for identification.
The nests were described as large, shallow cups of grass, roots and leaves, apparently willow-leaves, lined with soft grass and then with hair or fur. In one nest the inner lining was all of goats’ hair, in the other two fur, which was principally that of the mouse hare. The nests were taken on the 7th May, 14th June and 6th July and contained four, five and four eggs respectively.
A curious point about the three clutches is that they vary from an unusually pale to an exceptionally deep blue for the eggs of this genus, otherwise they are quite characteristic of it.
The thirteen eggs average 21.3 x 15.5 mm. ; maxima 23.0 x 15.8 mm. ; minima 30.0 x 15.2 and 20.1 x 15.1 mm.
