Common loon
The common loon is a large member of the loon, or diver, family of birds. Loons are swimming and diving birds. They have very distinctive bodies: long and low-slung with spear-like beaks and blood-red eyes. In addition to their unusual bodies, they have an eerie, haunting call that some consider a characteristic sound of early summer. Common loons are the most widespread and well-known species of loon in North America.
