Seeing this Species

 

Salonga National Park, Democratic Republic of Congo

Salonga National Park is the world's second largest tropical rainforest national park, and largest in Africa. Situated at the heart of the central basin of the Congo river, this enormous 3,600,000 ha park is very isolated and accessible only by water [4]. Declared a World Heritage Site in 1984, it is the habitat of many endemic endangered species, notably the Bonobo, Congo peacock, forest elephant and African slender-snouted crocodile.

 

Probability of success: There is apparently high densities of Allen's Swamp Monkey here [3].
