BWINDI MOUNTAINS, UGANDA: A Silverback male mountain Gorilla sits in the dense jungle canopy on the edge of Uganda's Bwindi National Park in this 29, January 2007 photo. Bwindi, or the 'Impenetrable Forest' as it is known to many tourists is home to the majority of Uganda's rare and endangered mountain gorilla population where plans are underway to habituate two more gorilla family groups to counter growing demand from a flourishing gorilla trek tourism business, a major source of income for the Uganda tourism Authority.
