White-winged Snowfinch (Montifringilla nivalis)
Raven (Corvus corax)
Unmistakalble where there is no overlap with Snow Bunting (almost always). Anonymous brown bird with white wing patch when seen foraging on ground. Views in flight are dominated by the white on wings and tail. Fairly long-tailed and passer-like. Distinguishable from Snow Bunting in all plumages by the combination of grey head and brown back. Bill dark in breeding season, and yellowish in winter. Female similar to male but slightly duller coloured. Does not perch in trees. Erect posture and frequent tail-flicking when foraging on the ground. Flight less loose than Snow Bunting, with more frequent glides on stiff wings.
Sound:Rich repertoire. Song a staccato, variable phrase, consisting of short burst of sharp chattering in uneven tempo. The timbre is ringing, rich in harmonics and partly rolling. Among the various contact call the commonest are a high-pitched, sharp "zeet", a deeper, Brambling-like "veet, or a sparrow-like "peea". Alarm call a rolling "trr-r-r-rt", resembling Crested Tit.

Buzzard size and largest passerine in the region. All black with very heavy bill, flat crown and shaggy throat. Long, broad wings and wedge-shaped tail. Superb, powerful and often playful flight. Often soars like a raptor.
Sound:Quite varied repertoire. Most heard sound a short, coarse, but resonant "korrk. Other sounds may be surprisingly resonant and pure, like a ringing "clong" etc. Shows even more variation when courting.
