More info: Loons are swimming and diving birds. They are a migratory species that spend the breeding season on inland lakes and overwinter on the ocean. They arrive on their breeding lakes shortly after the ice goes out in the spring and remain late into the fall
Loons have very distinctive bodies: long and low-slung with spear-like beaks and blood-red eyes. Loons walk in a clumsy way on land due to the fact that their legs are situated to the rear of their body – a fact which makes them strong swimmers.
Loons have an eerie, haunting call that some consider a characteristic sound of early summer.
There are five species or types of loon that can be spotted in the United States: the Red-throated Loon, Pacific Loon, Common Loon, Yellow-billed Loon, and Arctic Loon. Of these species, the Common Loon is the most widespread and well-known. It is the only loon species that breeds as far south as New Hampshire.
