Loons are the size of a large duck or a small goose. Loons can be hard to find because they are shy around people. The name "loon" is from the Scandinavian word for "clumsy". Loons are the state bird of Minnesota. Loons are found in most parts of North America (there are five North American species) and northern Eurasia. They enjoy cool climates in the summer and migrate to ocean coasts in the winter.
