The Hoatizin, a bizarre bird of South America's rainforest. A chicken-sized bird that eats only leaves, the hoatzin flies in short bursts. Their chicks, however, have a fascinating swimming ability! When threatened by predators the chicks jump from their nests into the river below and swim to safety. Once they have outsdistanced their predators they climb from the water using special claws on the ends of their wings to scale low hanging vines.
