Hardhead: Facts You Won't Believe!

Hardhead facts can be interesting to many.

The hardhead duck, also known as the Australian white-eyed duck, is the family of birds that is the only diving duck found in Australia. It is scientifically known as hardhead Aythya australis. They are medium-sized birds that are commonly found in wetlands, swarms, and freshwater. Overall, it is chocolate brown in color. Apart from southeast Australia being the major place for their presence, they are also found in New Guinea and other islands in limited numbers. They generally weigh 800-900 g and some even up to 1 kg.

The white-eyed duck usually stays in areas of favorable habitat, but they migrate great distances when drought threatens. They spend most of their lives in freshwater, and they are rarely seen in coastal marine areas or land. In Australia, when the weather conditions are favorable with high rainfall years that create inland lakes and large wetlands, these birds are less nomadic and breed in large numbers. Their powerful webbed feet make them very proficient swimmers. These ducks feed on aquatic plants and vertebrates, mussels, small fish, and shellfish. Read on to learn more about this diving duck.
