Terrestrial Behavior in Titi Monkeys (Callicebus, Cheracebus, and Plecturocebus): Potential Correlates, Patterns, and Differences between Genera
Diet of a Group of Callicebus torquatus lugens (Humboldt, 1812) During the Annual Resource Bottleneck in Amazonian Colombia
Aspects of the ranging pattern in a group of wild woolly monkeys (Lagothrix lagothricha)
A group of woolly monkeys (Lagothrix lagothricha), studied for 1,800 hr from June 1984 until September 1987 in the eastern Colombian Amazon, used a home range of about 760 ha, 90% of which overlapped the ranges of three other groups. Home range use varied throughout the year, correlating in part with variations in fruit production. The home range exhibited a nonexclusive “core area” in the floristically most diverse part of the home range, althou…

Callicebus torquatus is not a white‐sand specialist
The hypothesis of Kinzey and Gentry [ Primate Ecology: Problem Oriented Field Studies . New York, John Wiley & Sons, 1979] that Callicebus torquatus may be specialized for living in vegetation on white sand was evaluated by reviewing all observations I made of this species, where the substrate had been noted, and including some collection sites of J. Hernández Camacho. There was no evidence for the white‐sand hypothesis. Instead, Callicebus torqu…
Contiguous distribution of two species of Cebus monkeys in El Tuparro National Park, Colombia
The geographic distribution of two congeneric monkeys ( Cebus albifrons and C. apella ) was studied in El Tuparro National Park in the llanos of eastern Colombia. Extensive trips were undertaken by land and river to collect 268 precisely located groups of these two species. The distributions of these monkeys were generally mutually exclusive and parapatric, contrasting with their known sympatry in closed‐canopy rainforest farther to the south. Th…
