The Ruddy Duck is a stiff-tailed duck from North America and the Andes of South America.

The Ruddy Duck is now established in the United Kingdom from escapees and they have also widely spread across Europe.

Due to the Ruddy Ducks aggressive courting behaviour and its tendency to interbreed with the native White Headed Duck, there is a controversial scheme to extirpate the duck as a British breeding species.
