Perisoreus infaustus

The Siberian jay is the smallest of the western Palearctic corvids, about 30cm long and 75–90g, with a widespread distribution in the coniferous forests of North Eurasia. The plumage is grey-brown with a darker brown crown and a paler throat, rusty-red in a panel near the wing-bend, on the undertail coverts and on the sides of the tail. The sexes are similar and the eggs are pale green, blue or grey spotted with grey (Wikipedia, general species account).

Both sexes sing, mainly during the breeding season and from a short distance away, with a wide repertoire of sounds. The general species text used here does not describe its status in China (Wikipedia, general species account).
