Goldfinch (Carduelis carduelis)
Rook (Corvus frugilegus)
Plumage stunningly colourful. Adults easily recognized by red face boldly framed in black and white. In all plumages; black wings with broad yellow panels, forked tail with white patches, and flashing white rump. Bill fairly long and pointed. Juveniles lack the red, black and white head, and are best identified by the contrasting wing-panel and white rump/tail patches. Light and bouncing flight, with bursts of wing-beats and variable acceleration.
Sound:Contact-call distinct, and also constitutes a major part of the song. A sharp and explosive "witt", or "tzee-witt". Sometimes given as a single syllable, di- or trisyllabic, or as continuous series. The song is comprised of rapid series of the contact call, interrupted by drawn-out melodic notes and trills. Other calls: A harsh budgerigar or house martin-like "trrrtt-trrrrt".

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.
