Merganser Ducks

Mergus are seaducks that primarily feed on fish. Along with the Smew and Hooded Merganser, they are therefore often known as “sawbills” – so named because of the serrated edges to their bills to help them grip their slippery prey.

Most of the merganser species favor riverine habitats, the exception being the Red-breasted Merganser, which is common at sea.
