Loon

The loons (N.Am.) or divers (UK/Ireland) are a group of aquatic birds found in many parts of North America and northern Europe. A loon is the size of a large duck or small goose, which it somewhat resembles in shape when swimming.

The plumage is largely black-and-white, with grey on the head and neck in some species, and a white belly, and all species have a spear-shaped bill. All living species of loons are members of one genus (Gavia) in a family (Gaviidae), and order (Gaviiformes) all of their own.
