Appearance:

Relatively characterless plumage. Differs from Linnet in warmer, yellowish base colour, yellow bill (grey in breeding plumage), bolder wing-bars and coarsely streaked back. Male with pinkish rump. Told from Redpoll by white base of primaries (like Linnet), and missing red and black head markings. Slightly longer tail and shorter bill than Linnet.

Sound:

Contact call a short "chep" given in series, similar to Brambling, Redpoll and Linnet. Easiest identified by other distinct call given both in flight and on ground; a peculiar, nasal and twangy "twite", from which the species name originates. Each "twite" gives the impression of the pitch being "out of control", like cartoon-like sound-effects. Song a rapid alternation of trills and nasal "twites", given in an even tempo with phrases of variable length. Lacks Linnet's frequent inclusion of "gig-gig" sounds.

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.
