Fostering Appropriate Behavior in Rehabilitant Orangutans (Pongo pygmaeus)
Orangutan Cultures and the Evolution of Material Culture
Geographic variation in some aspects of chimpanzee behavior has been interpreted as evidence for culture. Here we document similar geographic variation in orangutan behaviors. Moreover, as expected under a cultural interpretation, we find a correlation between geographic distance and cultural difference, a correlation between the abundance of opportunities for social learning and the size of the local cultural repertoire, and no effect of habitat…
A preliminary study of food selection by the orangutan in relation to plant quality
Postcrania and the specific mate recognition system
On the Comparison of Primate Social Systems
Birth spacing patterns in humans and apes
Comparative studies of birth interval dynamics in wild primates suffer from several problems of analysis and interpretation: (1) the data are always right‐censored, (2) sample sizes are usually small, (3) the distribution of birth intervals is expected to be non‐normal, (4) early offspring mortality is a confounding variable, and (5) differences in life history (e.g., presence or absence of menopause) can complicate interpretation of the results.…

Orangutan sociality at Tanjung Puting
During a four‐year period, more than 6,800 hours of observation were collected on 58 individually recognized wild orangutans in a 35‐km 2 study area at the Tanjung Puting Reserve, Kalimantan Tengah (Central Indonesian Borneo). As in other areas, although small temporary associations of orangutans recurred, the basic units of populations consisted of (1) adult males, (2) adult females with one or two dependent offspring, and (3) independent immatu…
Subadult male orangutan sociality and reproductive behavior at Tanjung Puting
During a four‐year period at Tanjung Puting Reserve, Central Indonesian Borneo, subadult males were observed for 670.5 observation hours, 463 hours of which were as focal individuals. Subadult males were quite gregarious, participating in groupings for 40.9% of the time they were observed as targets. Subadult male sociality centered around females; 83% of the time subadult males spent in groupings was exclusively with females, as compared to 3% o…
Brief report
An immature crab‐eating macaque ( Macaca fascicularis ), which was sitting on the river bank near the Orangutan Research and Conservation Project base camp in the Tanjung Puting Reserve, Kalimantan Tengah, Indonesia, was seized by a crocodile which rapidly emerged from the water and then resubmerged with the monkey in its jaws. As crocodile populations are in a decline throughout Borneo, crocodile predation on crab‐eating macaques was probably mo…
