Arctic Redpoll (Acanthis hornemanni)
House Sparrow (Passer domesticus)
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.

CCMale told from Tree Sparrow by grey crown, grey cheeks with no cheek-patch, larger black bib and grey rump. Female rather featureless, and thus not likely to be confused with Tree Sparrow. Confusion with female Scarlet Rosefinch possible, but underparts unstreaked. Profile of House Sparrow differs from Tree Sparrow by larger, less rounded head and less heavy bill.
Sound:Most calls very similar to Tree Sparrow, but lacks said species' distinct high pitched call (chew-itt), and alarm call is less dry and raucous. Song a primitive, monosyllabic, or slightly disyllabic "chilp", hard to distinguish from Tree Sparrow.
