Demon Duck

The Demon Duck is a species of large fligless 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 second largest species of modern day bird in the world, about 420 pounds, almost 200 pounds bigger than an African ostrich, but the moa and the elephant bird is much bigger than a Genyornis or demon duck.
