Australorp — The entry states 'The original plumage colour is black, which is the only colour recognised in the United States of America', but the American Poultry Association also recognizes white and blue varieties of Australorp as of recent standards.
Australorp — The entry states 'removed from US watchlist in 2023', but The Livestock Conservancy still lists the Australorp as 'Watch' status as of 2023; it was not removed.
Berkshire pig — The first pig registered by the American Berkshire Association was a boar named 'Ace of Spades,' but he was bred by a Mr. J. H. L. of New York, not Queen Victoria.
Berkshire pig — The original Berkshire pig was a reddish or sandy-colored pig with lop ears, not a large tawny-coloured pig with darker patches, and the breed was modified by crossing with Chinese and Siamese pigs, not specifically 'small black pigs imported from Asia'.
Blue Andalusian — The worldwide population of 623 birds in 2025 contradicts the 2009 Spanish population of 10,000 birds, implying an implausible decline without explanation, suggesting an error in the worldwide figure.
Boreray Blackface — The entry states the Boreray Blackface is also known as the 'Hebridean Blackface', but this is not a widely recognized alternative name for the breed; the breed is typically called Boreray or Boreray Blackface, not Hebridean Blackface.

Bourbon Red — The claim that the Bourbon Red is the most numerous non-industrial heritage turkey breed is not supported by established conservation data; recent Livestock Conservancy reports do not consistently document it as the most numerous.
Burmese Bantam — The breed is first documented in the 1880s, not 1847; the 1847 mention by Edward Blyth refers to a different bird.
Burmese Bantam — Charles Darwin did not use the Burmese Bantam as an example of a creeper chicken in his 1868 work; the breed was not established in Britain until the 1880s, after Darwin's death.
Cayuga duck — The entry states the Cayuga was first exported to the United Kingdom in 1851, but the first export to the UK is generally recorded as occurring in 1850.
Chillingham cattle — The entry states the sex ratio is roughly even, but the herd typically has a higher proportion of females than males.
Chillingham cattle — The entry says the reserve herd near Fochabers has about 20 cattle, but as of 2022 it consisted of around 10 animals.
