The Tibetan Siskin breeds in Sikkim, Tibet and Ladak, in which latter place Ward and Whymper’s collectors obtained a single nest on the 27th July, the parent bird of which was secured and is now in the Museum of the Bombay Natural History Society.
Before this Vidal had received the eggs from Otto Muller, taken in Native Sikkim at about 14,000 feet. One of these eggs and a clutch of three, sold by the Mullers to Dr. H. N. Coltart, are now in my collection, the latter dated 19.6.06, the former single egg 22, 6. 86, but I can trace no description of nest or any further details concerning the taking of the egga.
Both Masson and Macdonald also sent me eggs, said to have been of this bird and to have been taken at nearly 14,000 feet. The nests of these birds were described as having been made almost entirely of grass, mixed with roots and dead moss and lined with a felting of vegetable down. They were placed in Juniper-bushes close to the ground. The birds sent with the eggs were certainly of this species ; the eggs are what one would expect this bird to lay and are probably correct.
The eggs are like dull specimens of eggs of the Himalayan Green¬finch, a very pale blue, the larger ends speckled with dull dark red-brown, the specks mostly tiny but mixed with a few larger blotches. In two eggs the markings form dense rings, in the others they are dense at the larger end but form neither ring nor cap. They vary in size from 18.6 x 13.8 to 19.0 x 14.1 mm.
