His size and strength are not the river Congo to see if it arises as Chambeshi in northern Zambia. Once a year, the source region of the Congo is the arena for one of the largest wildlife spectacle of the world: Millions of bats boarded a tiny piece of wood to beat their bellies full of ripe fruit. The Chambeshi flows Bangweulu, in a giant swamp. Hidden in the jungle lurks the Shoebill on prey. Standing upright, this bird is almost as big as a man. To survive in the Congo, the animals had to adapt to extreme conditions. Thus, the evolution has produced unique beings here, for example, fish with lungs or wings or those who hunt on land go. The river follows the river journey continues into the jungle in the south east of the Democratic Republic of Congo. Behind the city of Kisangani, the Congo is wide and quiet, house-high sand islands pile up in the river. Made up of small jungle rivers, they form their own little habitats. Wondrous creatures such as the butterfly fish and Aalwels have here developed very own strategies to survive in nutrient-poor water. The Congo feeds the second largest rain forest in the world. It is the home of the forest elephant. Again and again, she is drawn to a single, magical place: the forest glade Dzanga Bai, which means as much as the village of elephants. With them come countless other forest dwellers. What makes this place so special? This is another secret of the Congo.
