In the Rwenzori mountains, the wide source area of the Nile contains a spectacular feature. One snow-covered peak reaches 5000 metres (5500 yards) above sea level. Underneath its glacier, a fairy-tale forest expands, covered with Giant Lobelia and Aster plants. In this damp and cold world, the stunningly beautiful Lobelia Scarlet-tufted Malachite Sunbird lives its life. The males defend their plants, until the female birds arrive from warmer climes for the mating season. Forests at lower altitudes provide a paradise for reptiles like the insect-hunting chameleons unique to these mountains. The source furthest away from the Nile delta lies in Rwanda´s Nyungwe National Park. Thirteen species of primates live there, most notably the truly acrobatic Angola Colobus.
