The common scoter (Melanitta nigra) is a large sea duck, 43–54 cm (17–21 in) in length, which breeds over the far north of Europe and the Palearctic east to the Olenyok River. The black scoter (M. americana) of North America and eastern Siberia was formerly considered to be a subspecies.
The common scoter was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Anas nigra. Linnaeus specified the type locality as Lapland, England. The common scoter is now one of six species placed in the genus Melanitta that was introduced in 1822 by the German zoologist Friedrich Boie. The genus name combines the Ancient Greek melas meaning "black" and netta meaning "duck". The common scoter was formerly considered to be conspecific with the black scoter (Melanitta americana) but the two taxa are now treated as separate species. The common scoter is monotypic: no subspecies are recognised.
The common scoter is characterised by its bulky shape and large bill. The male is all black with a bulbous bill which shows some yellow coloration around the nostrils. The female is a brown bird with... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Scoter sighting in Vienna on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 97th most-seen of the 126 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Common Scoter in Vienna on a given day, against under 5% in February to December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Scoter sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 16 cities where we can rate Common Scoter sightings, Vienna ranks 9th at under 5%, level with the leaders once rounded. The best odds are in Liverpool (United Kingdom, under 5%), Dublin (Ireland, under 5%) and Minsk (Belarus, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Scoter is recorded against all the birds logged in Vienna (15 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.
