“…Brown spider monkeys Ateles hybridus are one of the most endangered primates in the Neotropics (Mittermeier et al 2009), and only a single previous study has focused on describing their feeding behavior (Link et al 2012). At Serranía de Las Quinchas, an inter-Andean forest site in northern Colombia, brown spider monkeys fed almost exclusively on ripe, fleshy fruits all year (Link et al 2012) and only complemented their diet with leaves and other items for approximately 6% of the time they spent feeding.…”

Brown spider monkeys Ateles hybridus are one of the most threatened primates in the Neotropics. Most of the remaining populations of this species already live either in forest fragments or in areas that face imminent anthropogenic disturbance. Understanding how these animals cope with the challenge of living in small fragments, while at the same time being a large, frugivorous mammal is crucial to design effective conservation and management strategies. We studied the diet of wild A. hybridus and measured forest productivity in a small (~65 ha) fragment in the Magdalena Region of northern Colombia over a period of 26 mo. Spider monkeys at this site spent far less time feeding on fruits than reported in previous studies of Ateles spp. living in less fragmented sites. Moreover, we registered a high consumption of leaves in every month (on average 37% of their feeding time) as well as the consistent inclusion of decayed wood in the diet. Ficus trees can be considered staple feeding items, as they were present in high proportions in the monkeys' diet throughout the study. Although wild populations of spider monkeys can have flexible diets that include large proportions of leaves over long periods of time, they may also be exposed to a suboptimal diet which may have negative implications for their reproduction and well-being in the long run, further compromising the viability of wild populations living in disturbed habitats.

“…These regions are home to Peru's 3 endemic primates: the 'Vulnerable' Andean night monkey Aotus miconax, the 'Critically Endangered' Andean titi monkey Calicebus oenanthe, and the 'Critically Endangered' yellow-tailed woolly monkey Oreonax flavicauda (classification according to the International Union for Conservation of Nature [IUCN]). The latter has been listed by the International Primatological Society (IPS) as one of the world's 25 most threatened primate species 3 times since 2006 (Mittermeier et al , 2007(Mittermeier et al , 2009. Primates are especially sensitive to hunting pressures (Peres 2001) and are often used as indicators or flagship species for conservation efforts (Marsh & Mittermeier 1987, Dietz et al 1994, Harcourt 2000 and were thus the main focus of this study.…”

The yellow-tailed woolly monkey ( Lagothrix flavicauda) is Critically Endangered and endemic to a small area of the Andean forest in northern Peru. I collected data on the home ranges, daily path lengths, diet and habitat use of two groups of L. flavicauda. Group follows took place at La Esperanza, Amazonas department, for 15 months between October 2009 and February 2011. The study site comprised a matrix of disturbed primary and regenerating secondary cloud forest. Home ranges were between 95 and 147 ha using 95 % minimum convex polygons, and home range overlap between the two groups was 1.6 ha. The range used by both groups varied between the wet and dry seasons. Daily path lengths were between 1.03 and 1.2 km. Fruit was the most commonly consumed dietary item followed by leaves and insects; a total of 16 plant resources were identified. There was a significant increase in consumption of leaves and insects during the dry seasons. Both groups used a variety of habitats but were only occasionally observed to use areas of white-sand forest. Home range and daily path length estimates are similar to results from studies of other woolly monkeys ( Lagothrix spp.), although home ranges were among the smallest recorded for woolly monkeys. L. flavicauda at La Esperanza are less frugivorous than Lagothrix spp., and the estimates here are lower than those from the previous preliminary work at this site. My results suggest that L. flavicauda are able to survive in disturbed habitat with small home ranges and at high group densities. More research is urgently needed at other sites with different ecological conditions to enable proper conservation planning and actions.
