Appearance:

Similar to Starling, and may be difficult to tell apart in winter and immature plumages. Most birds are in breeding plumage from March on, completely lacking spots, and with a purple (not green) sheen. Flight feathers lacks pale fringes, and the overall look is much darker than Starling. Elongated head and throat feathers are slightly longer than in Starling. Winter and immature plumage birds difficult to identify, but has small and spearhead-shaped spots, and darker wings (due to lack of pale fringes). Leg colour generally paler pink, than Starling, but some overlap occurs.

Sound:

Similar to Starling in form and variation, but the long, descending whistling notes are more dominant and accented. Sometimes uttered as trills, or "stuttered". Whistles also used as contact calls when not breeding.

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.
