Great Northern Diver, or Loon

A long-bodied, low-slung diver. Many people consider the loon a symbol of wilderness; its iconic yodeling and haunting calls, heard by day or night, are characteristic sounds of early summer in the north woods and across lakes. In winter, silent and more subtly marked, the Common Loon inhabits coastal waters and large southern lakes. In such places they are solitary while feeding but may gather in loose flocks at night. The Common Loon is an indicator of aquatic health.
