Previously, wild orangutan feeding and ranging behaviors have been described only from populations in hilly or mountainous regions. The Tanjung Puting study focuses on an orangutan population in a swampy lowland area near sea level. Tanjung Puting also differs from other areas in the virtual absence of large figs, which are significant orangutan food sources elsewhere. During a 4-year period and 6804 hr of observation, focal orangutans were recorded in 11,338 foraging bouts accounting for 3805… 
Food preferences of Bornean orangutan in Lamandau Wildlife Sanctuary, Central Kalimantan
The Bornean orangutan (Pongo pygmaeus wurmbii) is one of the world’s most endangered primates. Orangutan food is highly varied, depending on its habitat. This research was conducted in Lamandau
Feeding ecology of Bornean orangutans (Pongo pygmaeus morio) in Danum Valley, Sabah, Malaysia: a 3‐year record including two mast fruitings
Resting increased as feeding decreased in the late stage of each fruiting season, suggesting that the orangutans adopted an energy‐minimizing strategy to survive the periods of fruit shortage by using energy stored during the fruit season.
Monthly range of adolescent orangutans (Pongo pygmaeus wurmbii) based on fruit availability in Tuanan Orangutan Research Station, Central Kalimantan, Indonesia
Adolescent orangutans responded by increasing their monthly ranging area during this time of high fruit availability and decreased their range when fruit vailability was low, and often used areas in their monthly range that had a high to medium abundance of fruit trees.
Grouping behavior of Sumatran orangutans (Pongo abelii) and Tapanuli orangutans (Pongo tapanuliensis) living in forest with low fruit abundance
Orangutans in Sikundur were more likely to form parties when fruit availability was higher, but the size of daily parties was not significantly affected by fruit availability, and between‐site differences in sociality seem to reflect differences in average fruit availability.
Adaptation to Forest Life During the Reintroduction Process of Immature Pongo abelii
It is concluded that social interactions with conspecifics and humans, especially during an early developmental period, can affect adaptation to forest life and probably also influence the success of orangutan reintroduction processes.
Investigating Constraints on the Survival of Orangutans Across Borneo and Sumatra
Investigating the factors constraining the orangutans' ability to inhabit different areas of Borneo and Sumatra, as well as the social group size they are potentially able to adopt in their habitats, finds that resting time was a key behavioral limitation on orangutan distribution.
Female-Female Competition in Bornean Orangutans
Preliminary evidence for core area defense and passive range exclusion may be among the mechanisms responsible for maintaining distinct adult female core areas in Bornean orangutan ranging patterns and feeding competition.
Pedological Analysis of Geophagic Behaviour in Captive Borneo Orangutan (Pongo pygmaeus)
Geophagy (soil-eating) is one of the well-known behaviours in many primate species, but the factors influencing this behaviour have been less known. In the captive environment of Tama Zoological
Apes in Space: Saving an Imperilled Orangutan Population in Sumatra
Findings show that orangutans can survive, demographically, in certain types of degraded landscapes, foraging on a mixture of crops and wild fruits, however, the poor quality habitat offered by oil palm plantations is cause for concern.
Raiders of the Lost Bark: Orangutan Foraging Strategies in a Degraded Landscape
Orangutan adaptations for coexisting with humans are revealed, e.g. changes in temporal foraging patterns, which should be used for guiding the development of specific human-wildlife conflict mitigation strategies to lessen future crop-raiding and conflicts.


A field study on Sumatran orang utans (Pongo pygmaeus abelii Lesson 1827). Ecology, behaviour and conservation.
Comparison of the behavioural repertoire of the Sumatran orang utan with that of the (gregarious) chimpanzee shows that the two species are closely related.

Comparisons with results of studies from other areas indicate that, once samples used in each study are made explicit and aggregations owing to chance encounters at major food sources excluded, orangutan sociality seems relatively consistent over the entire range in which the species is found.

The Orang-utan in Sabah Today
Anyone who has ever kept orang-utans would agree that they are the most lovable and fascinating of animals. Their sad expressions and reserved ways give them a depth of character rare outside our own
On the evolution of Ape Social Systems
Despite theoretical advances in understanding the nature of social evolution (e.g. Hamilton, 1964; Trivers, 1972) a clear procedure for analysing the adaptive functions of social life has not yet

Observational study of behavior: sampling methods.
Seven major types of sampling for observational studies of social behavior have been found in the literature and the major strengths and weaknesses of each method are pointed out.
