White-bellied spider monkey  (Ateles belzebuth)

This New World monkey is found in Colombia, Brazil, Ecuador, Peru and Venezuela (1). Its range in Colombia has previously been greatly overestimated; it is found in the lowlands where there has been massive colonisation by humans, as well as in the piedmont forests of the north. It is currently the most threatened species in the Colombian Amazon (6). In Ecuador, the population has declined by 30% in the previous three generations (1). In Brazil, this monkey is found to the north-west of the Amazon (1).

Inhabits subtropical or tropical lowland and montane forests (1).
