Loons (NA)
From WikiBird
Gaviidae
The loon is a type of aquatic bird found in many parts of North America and northern Europe. A loon is the size of a large duck, to which it is unrelated; its plumage is largely grey or black, and it has a spear-shaped bill. The loons compose a genus (Gavia), family (Gaviidae), and order (Gaviiformes) all their own.
