Editing Common scoter (section)

==Description==
The common scoter is characterised by its bulky shape and large bill. The male is all black with a bulbous bill which shows some yellow coloration around the [[nostril]]s. The female is a brown [[bird]] with pale cheeks, very similar to female black scoter. This species can be distinguished from other scoters, apart from black scoter, by the lack of white anywhere on the drake and the more extensive pale areas on the female. The black scoter and common scoter have diagnosably distinct vocalisations.<ref name=Sangster2009/>
