In flight, the Red-throated Diver has a distinctive profile its small feet do not project far past the end of its body, its head and neck droop bel In flight, the Red-throated Diver has a distinctive profile its small feet do not project far past the end of its body, its head and neck droop below the horizonta Within weeks, this first down is replaced by a second, paler set of down feathers, which are in turn replaced by developing juvenile feathers. Primarily dark brown to dark grey above, it is slightly paler on the sides of its head and neck, as well as on its throat, chest, and flanks, with a pale grey lower breast and belly. The nostrils are narrow slits located near the base of the bill, and the iris is reddish.Īn adult in non-breeding plumage shows the speckled back which gives the bird its specific name.When it first emerges from its egg, the young Red-throated Diver is covered with fine soft down feathers. Though the colour of the bill changes from black in summer to pale grey in winter, the timing of the colour change does not necessarily correspond to that of the bird's overall plumage change. Its bill is thin, straight and sharp, and the bird often holds it at an uptilted angle. The non-breeding plumage is drabber with the chin, foreneck and much of the face white, and considerable white speckling on the dark mantle. It is the only diver with an all-dark back in breeding plumage. In breeding plumage, the adult has a grey head and neck (with narrow black and white stripes on the back of the neck), a triangular red throat patch, white underparts and a dark mantle. The sexes are similar, although males tend to be slightly larger and heavier than females. Like all divers, it is long-bodied and short-necked, with its legs set far back on its body. The Red-throated Diver is the smallest and lightest of the world's diver species, ranging from 55–67 centimetres (22–26 in) in length with a 91–110 centimetres (36–43 in) wingspan, and averaging 1.4 kilograms (3.1 lb) in weight. The word "loon" is thought to have derived from the Swedish lom, the Old Norse or Icelandic lomr, or the Old Dutch loen, all of which mean "lame" or "clumsy", and is a probable reference to the difficulty that all divers have in moving about on land. "Diver" refers to the family's underwater method of hunting for prey, while "red-throated" is a straightforward reference to the bird's most distinctive breeding plumage feature. The specific epithet stellata is Latin for "set with stars" or "starry", and refers to the bird's speckled back in its non-breeding plumage. The genus name Gavia comes from the Latin for "sea mew", as used by ancient Roman naturalist Pliny the Elder. It is thought to have evolved in the Palearctic, and then to have expanded into the Nearctic. Its relationship to the four other divers is complex though all belong to the same genus, it differs more than any of the others in terms of morphology, behaviour, ecology and breeding biology.

By 1788, however, German naturalist Johann Reinhold Forster realized that grebes and divers were different enough to warrant separate genera, and moved the Red-throated Diver (along with all other diver species) to its present genus. Pontoppidan initially placed the species in the now-defunct genus Colymbus, which contained grebes as well as divers. A monogamous species, the Red-throated Diver forms long-term pair bonds.įirst described by Danish naturalist Erik Pontoppidan in 1763, the Red-throated Diver is a monotypic species, with no distinctive subspecies despite its large Holarctic range. Fish form the bulk of the diet, with invertebrates and plants sometimes eaten as well. During the breeding season, it acquires the distinctive reddish throat which gives rise to its common name. It is the smallest and most widely distributed member of the loon or diver family.Īround 55–67 centimetres (22–26 in) in length, the Red-throated Diver is a nondescript bird in winter, greyish above fading to white below. The Red-throated Diver (Gavia stellata), known in North America as the Red-throated Loon, is a migratory aquatic bird that is found in the temperate regions of the northern hemisphere.
