Surf Scoters are large colorful sea ducks. The male Surf Scoter’s huge red-orange bill is a great tool for eating some of a Surf Scoter’s favorite foods: hard-shelled mollusks like clams and mussels that stick onto rocks. The scoter swallows them whole, crushing them in its gizzard, which is filled with sand. (Source: https://www.birdnote.org/listen/shows/surf-scoters-stand-out)
