Arctic Redpoll (Acanthis hornemanni)
Chiffchaff (Phylloscopus collybita)
Differs from Common Redpoll by white, almost unstreaked rump (young birds may have some streaks). Under tail coverts white, with only very narrow black center, or no black at all. Upperparts greyer, underparts whiter with less prominent streaking. Wing bars brighter. Bill shorter and less deep, and face "flatter". Juveniles difficult to distinguish from Common Redpoll, even when held in hand. Species status debated.
Sound:Very similar to Common Redpoll, but possibly with a softer tone and slightly longer pauses between each syllable. See Common Redpoll.

CCOlive 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.
