Common Scoter (Melanitta nigra)
Rook (Corvus frugilegus)
Medium sized diving duck. Male all black except orange spot on bill. Female dark brown with contrasting light grey cheeks. Differs from Velvet Scoter in all plumages by lack of white wing-bars, and longer tail. Birds resting on the surface characteristically bow their head when occasionally flapping the wings. Wings held tight against body when diving. Last two characters usable for identification at very long range. Also tend to stay closer together in groups than Velvet Scoter.
Sound:More vocal than other Scoters. Short, whistling sounds, sometimes reminiscent of a male teal, but a little bit deeper in pitch.

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.
