It doesn't look like, but this bird is related to the duck family. It is large (75-95cm), can weight up to 4-5 kg consuming roots, leaves, flowers, aquatic vegetation, seeds or small invertebrates. It's an excellent swimmer and flier living in wetlands. Because its meat is not very tasty, it is rarely hunted for meat. Actually the hunters hate them, because they act as sentinels and emit very loud calls (they scream) which can be heard more than 3 kilometers away.
