Physical 

The male Black Scoter is a striking bird, entirely black with the exception of its bright orange-yellow bill and a small white patch on the wing. It measures about 17 to 21 inches in length and has a wingspan of roughly 33 inches. Females are more muted, with dark brown plumage and a paler face, and a dark cap that contrasts with the lighter cheek.

Habitat

Black Scoters frequent coastal marine environments, especially during non-breeding seasons. They can be found on open waters, bays, and estuaries. For breeding, they prefer freshwater lakes and ponds in northern boreal forests or Arctic tundra.

Feeding 

Diving beneath the water’s surface, Black Scoters search for mollusks, crustaceans, and small fish. They have a particular fondness for mussels and will often be seen in areas abundant in this shellfish.
