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.
