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:

Differs from Arctic Tern in longer head, and more orangy red, rather than deep red, bill. Tip of bill usually black. Legs longer, but tail streamers shorter than AT. Underparts of primaries with diffusely bordered dark trailing edge (sharply bordered in Arctic Tern). Upper side of primaries with dark wedge (less apparent in winter). Secondaries opaque. Crest more apparent than in Arctic Tern and underside whiter. Juveniles with buff back.

Sound:

Similar to Arctic Tern but deeper. Lacks latter's high pitched "tip-tip-tip" call, and the drawn out "kree-aaahh" call falls more distinctly in pitch.
