The common pochard (Aythya ferina), known simply as pochard in the United Kingdom, is a medium-sized diving duck in the family Anatidae. It is widespread across the Palearctic. It breeds primarily in Scandinavia and the steppe regions of Siberia, and winters farther south and west.
Swedish taxonomist Carl Linnaeus first assigned a scientific name to the common pochard in the tenth edition of his landmark treatise Systema Naturae; this was the first edition which included such names. He called the duck Anas ferina. In 1822, German zoologist Friedrich Boie created the genus Aythya for various diving ducks, and moved the common pochard to that new genus. Uptake of Aythya as the genus for the common pochard was mixed for much of the next century, with some authors leaving the duck in the genus Anas or assigning it to various other now-defunct genera instead. The common pochard is considered a superspecies with the canvasback. In the past, the redhead of North America was thought to be a subspecies, but the common pochard is now agreed to be monotypic, with no subspecies. It is known to have hybridised with tufted duck and ferruginous duck in captivity, and... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Common Pochard is recorded against all the birds logged in Nizhny Novgorod (44 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.
