Common pochard
species of bird
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.
Taxonomy and systematics
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 these known combinations resemble suspected hybrids seen in the wild, which may share the same parentage.
The public source identifies “Common pochard” as species of bird. This brief keeps that definition visible, then builds a research path around Common, pochard and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Common pochard”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 6, 2026. The linked authority identifier is Q26742. The Library of Congress control number is sh85103645. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1822.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
