Common Scoter Duck

The Common Scoter Duck is characterized by its bulky shape and large bill. The male is all black with a bulbous bill which shows some yellow coloration around the nostrils. 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.

Notes: – The Common Scoter Duck is a large sea duck which form large flocks over coastal waters during the winter.

The different types of wild ducks can be grouped into puddle, aka “dabbling” and diving ducks. The dabblers mostly feed in smaller bodies of shallow water or along shorelines, where they are able to tip their bodies forward to reach their food on the bottom. There are divers who feed in deeper water where they dive and pursue their quarry. Some of these birds, the Harlequin Duck for example, actually dives to the bottom of fast-flowing waters and feeds on life forms attached to rocks.
