Ruddy Duck

Oxyura jamaicensis

The ruddy duck is a species of duck, one of six extant species of stiff-tailed duck. In the 1940s, the ruddy duck was introduced to the United Kingdom, where it established a population. Outside the Americas, the ruddy duck is considered a highly invasive species, prompting many countries to initiate culling projects to eradicate it from the native ecosystem. Source
