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:

Small green and yellow finch with contrasting dark wings and tail. Underparts whitish with grey streaking. Secondaries, inner primaries and outer tail feathers with yellow base. Relatively long and pointed bill as opposed to Serin. Male distinct with black crown and bib, bright yellow chest, throat and hind-cheeks. Female less contrasty, with more prominent streaking. Juveniles paler and duller than adults, with even heavier streaking than females.

Sound:

Distinct calls and song. Most often heard is the sharp and disyllabic contact call: "doo-lee", with both notes descending. Sometimes given a in monosyllabic manner "dlyy". The contact call is also prominent in the improvised song. Other typical sounds in the song includes a peculiar wheeze, like someone sucking their teeth, and lots of expert mimicry.
