Nidification. This fine Magpie breeds both in Sikkim and South and East Tibet at heights over 10,000 feet and up to nearly 15,000 feet The nest is similar to that of the Common Magpie but is often placed comparatively low down in thorn-bushes. The eggs number from four to six in a full clutch, and are rather dark as a series but otherwise like those of other species of Pica. They are very big and forty-eight eggs average 38.7x26.7 mm.
The birds breed from early April, when there is still snow about, through May and rarely, possibly a second time, in June.
