Appearance:

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.

Appearance:

Similar to Reed Warbler but note very short primary projection, evenly coloured wings with dull tertials. Under tail-coverts almost white, with very little buff tinge. Legs overall darker than congeners. Immature birds with slightly paler legs and warmer upperparts and fringes to flight-feathers. Leaves a slimmer impression than Reed- and Marsh W., with flatter forehead and tapering bill. Posture often Sylvia-like with frequent cocking, flicking and fanning of tail.

Sound:

Contact call a short and sharp Lesser Whitethroat-like "tek", different from Mars W. Alarm call a dry, rolling "krrrreet", often with a register break splitting into high register overtones. Song recalls Marsh Warbler in timbre but is generally diagnostic. Tempo slow and deliberate, pace recalling that of Song Thrush, with marked pauses. Typical articulate, arpeggio-like whistling motifs alternated by mimicry are often repeated many times. Daytime song less typical than normal song at night, with faster pace and less repetition.
