Any of four species (genus Gavia) of diving birds of North America and Eurasia.

Loons range in length from 2 to 3 ft (60–90 cm). They have small pointed wings, webs between the front three toes, legs placed far back on the body, making walking awkward, and thick plumage that is mainly black or gray above and white below. They feed mainly on fishes, crustaceans, and insects. Almost wholly aquatic, they can swim long distances underwater and can dive to a depth of 200 ft (60 m). They are generally found singly or in pairs, but some species winter or migrate in flocks. They are known for their eerie, "laughing" cries.

bird
also called  diver  
 any of five species of diving birds (bird) constituting the genus Gavia, family Gaviidae. Loons were formerly included, along with the grebes (grebe), to which they bear a superficial resemblance, in the order Colymbiformes, but they are considered to constitute their own separate order. Loons range in length from 60 to 90 cm (2 to 3 feet). Characteristics include a strong tapered bill, small pointed wings, webs between the front three toes, and legs placed far back on the body, which makes walking awkward. Loons have thick plumage that is mainly black or gray above and white below. During the breeding season the dorsal plumage is patterned with white markings, except in the red-throated loon (Gavia stellata), which during the summer is distinguished by a reddish brown throat patch. In winter the red-throated loon develops white speckling on the back, while the other species lose these markings.

      Almost wholly aquatic, loons can swim long distances underwater and can dive from the surface to a depth of 60 metres (200 feet). Besides having solid bones, loons can further decrease their buoyancy for these dramatic dives by compressing air from their lungs, feathers (feather), and internal air sacs (air sac). (Young loons, however, are buoyant and pop up like corks from their first attempts at dives.) Loons are generally found singly or in pairs, but some species, especially the Arctic loon, or black-throated diver (G. arctica), winter or migrate (migration) in flocks. The voice is distinctive, including guttural sounds and the mournful, eerie wailing cries that in North America may have given rise to the common name loon. (Some sources suggest it arises from the Old Norse word lōmr, which means “to moan.”) Loons feed mainly on fishes (fish), crustaceans (crustacean), and insects (insect). The nest is usually a heap of vegetation at the water's edge, in which two (or, rarely, three) olive-brown spotted eggs (egg) are laid. The parents share the task of incubation. The chicks hatch in about 30 days and, as soon as their down is dry, enter the water with the parents. (Loons are precocial birds; that is, they are well-developed at birth.) Although loons are strong fliers, all but the small red-throated loon need a broad expanse of water for takeoff. Thus, except for G. stellata, they are limited to large lakes. The red-throated and arctic loons are virtually circumpolar in distribution, the latter being most abundant on the Pacific coast of North America.

      The common loon, or great northern diver (G. immer), is the most abundant loon in North America, and its haunting voice, heard in summer on northern wooded lakes, is considered a symbol of the wilderness. Because of its mournful songs, the Ojibwa considered the loon an omen of death, and the Cree saw it as the spirit of a warrior denied entry to heaven. Common loons make a variety of calls, which carry long distances across water. A wail calls to and locates (by response) a missing mate. A “yodel” is given in aggressive defense of territory. (Each male has a different version of this call, which persists year after year.) A tremolo of 8–10 notes, resembling human laughter, is heard in spring in the loon's defense of territory or chicks. It is the only call made in flight and is frequently combined with other calls. Parents also hoot or “kwuuk” to chicks that may have strayed too far away. Parents often swim with the young on their backs. The common loon's counterpart across Eurasia is the similar white- (or yellow-) billed diver (G. adamsii).
