Harlequin Duck
Histrionicus histrionicus (Linnaeus, 1758)
HQ
HARDU
2110
Family: Anseriformes > Anatidae
Males of this small duck are unmistakable with their blue plumage. Sadly, this is only an extremely rare winter visitor to northern Britain from the northernmost reaches of Europe.
When engaged in behavioural interactions, the Harlequin Duck gives a series of distinctly unduck-like squeaks, the source of one of its local names in Canada: 'sea mouse'.
