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:

An all shiny black crow with diagnostic bare, pale grey base of bill, and "baggy trousers". Juveniles lacks bare bill base and are difficult to separate from Carrion Crow. Young Rooks however, has a steeper forehead and more conical bill with less curved culmen. Tail is more rounded and base of wings more narrow. Flight action includes less gliding than Carrion Crow, and individuals are more spread when a flock flies.

Sound:

Makes similar caws as Carrion Crow, but is harsher, softer, flatter with less rolling r's. Also gives a varied song of soft gurgling and rattling sounds, interwoven with calls at breeding ground.
