The red-throated loon (North America) or red-throated diver (Britain and Ireland) (Gavia stellata) is a migratory aquatic bird found in the Northern Hemisphere. The most widely distributed member of the loon or diver family, it breeds primarily in Arctic regions, and it winters in northern coastal waters. Ranging from 55 to 67 centimetres (22 to 26 in) in length, the red-throated loon is the smallest and lightest of the world's loons. In winter, it is a nondescript bird, greyish above, fading to white below. During the breeding season, it acquires the distinctive reddish throat patch, which is the basis for its common name. Fish form the bulk of its diet, though amphibians, invertebrates, and plant material are sometimes eaten as well. A monogamous species, red-throated loons form long-term pair bonds. Both members of the pair help to build the nest, incubate the eggs (generally two per clutch), and feed the hatched young.
The red-throated loon has a large global population and a significant global range, though some populations are declining. Oil spills, habitat degradation, pollution, and fishing nets are among the major threats this species faces. Natural predators—including various gull species, and both red and Arctic foxes, will take eggs and young. The species is protected by international treaties. Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-throated Loon sighting in Moscow on a given day, based on 59 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 171 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and October
In those months about 10% of wildlife watchers report a Red-throated Loon in Moscow on a given day, against under 5% in July–September and November–May, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red-throated Loon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 26
Of the 26 cities where we can rate Red-throated Loon sightings, Moscow ranks 3rd at under 5%. The best odds are in Antalya (Turkey, about 10%) and Dublin (Ireland, under 5%).
GBIF citizen-science records
It is estimated from how often the Red-throated Loon is recorded against all the birds logged in Moscow (59 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
