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.

Appearance:

Breeding male easily recognized by all black head, prominent white moustache stripe and white collar. Rufous greater coverts in young birds. Females and juveniles otherwise plain and rather characterless, and are easily confused with other rare buntings. Reed bunting however, lacks the pale eye-ring and plain cheeks of Little Bunting, and the rufous rump of Rustic Bunting.

Sound:

Song variable between individuals and breeding status: A short sequence of 3-5 brittle and buzzing sounds, repeated consistently with marked pauses. Last sound in phrase often has a conclusive feel, but not always. Paired males sing slower than unpaired. Unpaired male song also more contracted, making the pauses between each phrase stand out. Contact call a sharp, descending and drawn "tseeeoo". A bit similar to Yellow Wagtail, but not as sharp and explosive. In migration a thick, and unmusical "chong" is often heard.
