a young hoatzin ( What-seen ) knows how to get away fast. yhe hoatzin is a bird of tropical South America. it builds its nest directly over streams and other bodies of water. when a hoatzin chick is threatened in its nest by another animal, such as a monkey, it drives into the water and swims away. it often makes its escape by swimming underwater. to getbback home, the chick uses something that few other birds have: wing claws. Digging in with the two claws it has on each wing along with its bill and its feet the chick climbs a tree. it usually doesn't return to its nest, but finds a perch nearby. its parents will visit it there and feed it. when the hoatzin chick is about 10-15 weeks old, it begins to learn to fly. once the chick flies, it loses it wing claws.
