Siberian Jay (Perisoreus infaustus)

Marked transition between dark neck and white front, and the dark grey crown extends below the eye. In all plumages: Heavier neck and bill than Red-Throated, and bill usually held straight. Visibly protruding chest when swimming. Head shape sometimes squarish. Usually shows big white flank patch.
Sound:Song: a strong, very resonant, full bodied, low whistling with most syllables rising in pitch: "co clooo-eee, co clooo-eee, co clooo-eee". Also a short grunting "karr".

CCPretty unmistakable. Dark brown to grey plumage, with conspicuous rusty patches on wings and tail. Noticeably smaller and slimmer than Jay. Seems all brown when perched, but rusty wings and tail immediately apparent when flying. Flight undulated and several birds are usually following eachother. A social, and very little shy bird.
Sound:Rich repertoire but not very vocal. Song a subdued chirping stream of squeaky notes and mimicry. Alarm call a loud, mewing, buzzard-like "eeeeaaah".
