Demon Duck

The Demon Duck is a species of bird that evolved from a prehistoric Genyornis that survived and remained mostly unchanged since the Pleistocene. It is named because it can sometimes get aggressive to humans and other animals in its area if it has high amount of testosterone in its body. Unlike its ancestors, It is usually a herbivore that feeds mostly on fruit, nuts, leaves, and shrubs, but also feeds on insects, fish, and carrion to supplement its diet. It is indigenous to Australian outbacks. It is the world's largest species of modern day bird of Pacific islands, about 420 pounds, almost 200 pounds bigger than an African ostrich, but the extinct moa was much bigger than a modern Genyornis or demon duck.
