White-winged Snowfinch (Montifringilla nivalis)
Chiffchaff (Phylloscopus collybita)
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.

Olive green upperparts, yellowish chest with gradual transition to off-white belly. Very similar to Willow Warbler, and most field characters are subtle and often hard to see. Distinguished by (usually) black, or dark-brown legs, only faint dark framing to ear-coverts, less marked supercilium. Shorter primary projection (1/2 to 2/3'rds the lenght of tertials), with regularly spaced tips (visible when wing folded). Wings more fan-shaped and less pointed than in Willow Warbler. Juveniles much less yellow below than in W.Warbler. Generally leaves a duller and greyer impression than W. Warbler, but plumage very variable. Frequently flicks tail, even sideways. Generally also more active when moving among the foliage.
Sound:Contact/alarm call a soft, plaintive ascending "hooeet". Similar to W.Warbler, but shorter with a monosyllabic feel. Song a very distinct: "chiff-chaff-chiff-chiff-chaff-chiff", in a regular clock-like rhythm. Each syllable at seemingly random pitch, but no large intervals tonally. Sometimes "get stuck" at one note.
