The surf scoter (Melanitta perspicillata) is a large sea duck native to North America. Adult males are almost entirely black with characteristic white patches on the forehead and the nape and adult females are slightly smaller and browner. Surf scoters breed in Northern Canada and Alaska and winter along the Pacific and Atlantic coasts of North America. They are diving ducks and mainly feed on benthic invertebrates, mussels representing an important part of their diet.
In 1750 the English naturalist George Edwards included an illustration and a description of the surf scoter in the third volume of his A Natural History of Uncommon Birds. He used the English name "The great black duck from Hudson's Bay". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay area of Canada by James Isham. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the surf scoter with the ducks and geese in the genus Anas. Linnaeus included a brief description, coined the binomial name Anas perspicillata and cited Edwards' work. The surf scoter is now one of six species placed... Wikipedia →

Rare
Under 5% of wildlife watchers report a Surf Scoter sighting in Miami on a given day, based on 488 verified sightings from GBIF citizen-science data. It is the 168th most-seen of the 325 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.
December
In that month about 10% of wildlife watchers report a Surf Scoter in Miami on a given day, against under 5% in January to November, the lowest months. That is one of Miami's driest months, with about 50 mm of rain against 190 mm in June.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Surf 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.
8th of 20
Of the 20 cities where we can rate Surf Scoter sightings, Miami ranks 8th at under 5%. The best odds are in Seattle (United States, about 10%), San Diego (United States, about 10%) and San Francisco (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Surf Scoter is recorded against all the birds logged in Miami (488 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.
