Yes, besides gorilla and chimpanzee trekking Rwanda is also a wonderful bird watcher's paradise.  Rwanda's Nyungwe National Park is home to over 300 bird species. Twenty-seven of these can only be found in the Albertine Rift.
Birdlife International described it as "the most important site for biodiversity conservation in Rwanda".  During a bird watching safari, travellers enjoy a wonderful trail through the forest grounds as bird song are all around.  The expert guide identifies birds, including the Rwenzori Turaco and the Grey-Chested Kakamega.
