Canada Jay
Perisoreus canadensis
The Canada jay is a relatively large songbird, though smaller than other jays. A typical adult Canada jay is between 25 and 33 cm (9.8 and 13.0 in) long. Its wingspan is around 45 cm (18 in). It weighs about 65 to 70 g (2.3 to 2.5 oz). Adults have medium grey back feathers with a lighter grey underside. Its head is mostly white with a dark grey or black nape and hood, with a short black beak and dark eyes. The long tail is medium grey with lighter tips. The legs and feet are black. The plumage is thick, providing insulation in the bird's cold native habitat.

Siberian Jay
Perisoreus infaustus
The Siberian jay is the smallest of the western Palearctic corvids, weighing 75 to 90 g (2.6 to 3.2 oz) and measuring about 30 centimetres (12 inches) in length. The adult plumage is greyish brown, with a dark brown head, paler forehead and buff breast. The rump is yellowish and the chin and throat are grey. There is also rufous streaking on the outer feathers, and the bill and legs are black. Their overall colouration is fairly inconspicuous to visually conceal them from predators within their forest habitat. Voice: The Siberian jay is mostly silent, but it can emit a loud screech similar to that of a buzzard (Buteo spp.). Both sexes perform the song, which is mainly heard during the breeding season from a short distance away, and it comprises a wide repertoire of sounds. These range from sequences of separate soft and harsh notes to bouts of whistling, creaking and trilling.
