(22) Urocissa flavirostris flavirostris (Blyth).

This Yellow-billed Magpie breeds in Sikkim, Bhutan and, almost certainly, in the sub-Himalayas between 5,000 and 9,000 feet in Assam, North of the Brahmapootra.
Very little is on record about this bird’s breeding. A single egg was sent to me with nest and parent taken on the 7th May, 1917, on the Sikkim-Tibet road and labelled “Chumbi.” The nest is a shallow cup of sticks, quite well made for a Magpie’s, and lined with roots, and it had been taken from a tree, evidently a Pine of some kind, at about 15 feet from the ground. The egg, judging from those taken later by Osmaston, is abnormal. The ground¬colour is pale cream, richly blotched with bright reddish-brown, with a few secondary blotches of pale neutral tint. It measures 32.0 x 22.9 mm. and was taken on the 7th May, probably at an elevation of about 9,000 feet, a nest and eggs of a Tragopan being taken close by.
Osmaston took two nests in Darjiling on the 23rd May and 3rd June, each containing four fresh eggs. He describes the nests—“open cup-shaped nests made of small sticks and lined with rootlets, rather small and flimsy nests in comparison with the size of the builder. Both nests were placed on small trees in open forest, one 15 feet from the ground and one 18 feet. They were taken at altitudes of 8,000 and 9,000 feet.” The eggs are handsome replicas of those of the next bird and can be matched with many of them.
Nine eggs average 34.8 x 23.4 mm. : maxima 37.1 x 23.9 and 34.5 x 24.1 mm. ; minima 32.0 x 22.9 and 32.2 x 22.8 mm.
