Mergellus albellus

Native Range: Eurasia

Notes: a tiny duck with strong sexual dimorphism; drake is mostly white-plumaged with black highlights; hen is grayer-bodied with a reddish-brown crown and white face; the silly name of this bird comes from the drake's call, which sounds like "smew"; bill has a serrated edge that helps hold slippery fish; nests in forests in tree cavities such as the abandoned holes of Black Woodpeckers; forms large flocks in winter.
