Perisoreus infaustus
The Siberian Jay, *Perisoreus infaustus*, is a charismatic medium-sized corvid, measuring 26-29 cm in length with a wingspan of 40-46 cm and weighing 75-95g. Its plumage is characterized by a sooty-brown cap and dark eye-stripe contrasting with paler cheeks, a grey-brown back, and striking rusty-red patches on the rump, tail, and flight feathers, giving it a warm, somewhat fluffy appearance.

Exclusively inhabits boreal and taiga forests, predominantly coniferous forests of spruce, pine, and fir, but also mixed stands. Typically found at low to mid-elevations.
Omnivorous and highly opportunistic, their diet primarily consists of insects (larvae and adults), spiders, berries, seeds (especially pine), fungi, small rodents, bird eggs and nestlings, and carrion. They are adept at finding and exploiting a wide range of food sources.
