Naming chimpanzees
Seasonal hunting for red colobus monkeys by Mahale chimpanzees
With the spread of red colobus hunting by Mahale chimpanzees after the 1990s, hunting became more concentrated from August to October when the party size of chimpanzees increased. In particular, infant red colobus monkeys seemed to be caught more frequently from July to September compared to other age-group prey
Male chimpanzee age affects red colobus monkey hunting success
We used data collected from 1976 to 2010 in Mahale, Tanzania, to explore longitudinal changes in red colobus hunting throughout the life histories of individual male chimpanzees. The relative frequency (z-scores) of successful red colobus hunts by male chimpanzees exhibited an inverted U-shaped distribution with age. Hunting success increases when males are between 8–20 years old. Males in adulthood (20–35 years of age) made the highest number of…
A lone chimpanzee mother–infant pair was indifferent to frequent leopard calls
Leopards are potential predators of wild chimpanzees where the two species are sympatric. However, the relationship between these two species in Mahale, Tanzania, is not so simple: chimpanzees can be eaten by leopards, but they also sometimes attack the leopard cubs and even deprive a leopard of prey. This report describes a case in which a mother–infant pair of chimpanzees in Mahale showed no significant response to repeated leopard rasping call…
Evolution of Humanity
In 1952, Kinji Imanishi wrote a thought-provoking essay on the nature of animal societies. In this essay, he applied the concept of human culture (which he referred to as Karuchua ) to nonhuman animals by giving different taxa a voice in a fable-like conversation, thereby aptly transcending speciesism. While thoroughly inspiring for scholars who have mastered the Japanese language, the essay was only known to non-Japanese-speakers by its English …
Greetings among female chimpanzees in Mahale, Tanzania
Greeting behaviors have been reported in several primate species, although their forms and context may vary across species. Chimpanzees ( Pan troglodytes ) greet each other in various ways when they meet; however, many recent studies of greetings in chimpanzees have mostly focused on pant grunt vocalizations, which are often viewed as equivalent to submissive signals. As most greetings in chimpanzees are directed toward adult males, either from o…

Wild chimpanzees deprived a leopard of its kill
A newborn infant chimpanzee snatched and cannibalized immediately after birth
OBJECTIVES: This study reports on the first observed case of a wild chimpanzee infant being snatched immediately after delivery and consequently cannibalized by an adult male in the Mahale Mountains, Tanzania. We demonstrate "maternity leave" from long-term data from the Mahale M group and suggest that it functions as a possible counterstrategy of mother chimpanzees against the risk of infanticide soon after delivery. MATERIALS AND METHODS: The s…

Lethal aggression in Pan is better explained by adaptive strategies than human impacts
Experimental Primate Archaeology
Non-human primates using stones in nature provide a rare opportunity to compare directly the behaviour of use with the resulting lithic artifacts. Wild Japanese macaques (Macaca fuscata) customarily do “stone handling” (SH = spontaneous, solitary, non-instrumental and seemingly playful manipulation of stones). Ten populations of monkeys show at least 48 behavioral variants, 13 of which entail repeated stone-on-stone or stone-on-substrate contact …
Brief Communication
If a social‐living animal has a long life span, permitting different generations to co‐exist within a social group, as is the case in many primate species, it can be beneficial for a parent to continue to support its weaned offspring to increase the latter's survival and/or reproductive success. Chimpanzees have an even longer period of dependence on their mothers' milk than do humans, and consequently, offspring younger than 4.5–5 years old cann…
Ranging behavior of Mahale chimpanzees
Ontogeny of a Social Custom in Wild Chimpanzees
Among cultural behaviors of chimpanzees, the developmental processes of complex skills involved in tool use are relatively well known. However, few studies have examined the ontogeny of social customs that do not require complex skills. Thus, in this study, we describe the developmental process of the grooming hand‐clasp (GHC), one of the well‐known social customs of chimpanzees at Mahale. We have collected 383 cases of GHC where at least one of …

Ethogram and Ethnography of Mahale Chimpanzees
This paper aims to compile an exhaustive list of the behavioral patterns exhibited by the chimpanzees of the Mahale Mountains National Park, Tanzania. The compilation is based on the glossary compiled by Goodall (1989), but a substantial numbers of new terms have been added. Thus, we list 316 simple anatomical terms, 81 complex anatomical terms, 37 simple functional terms, and 81 complex functional terms, in addition to 116 synonyms. The behavior…

Demography, female life history, and reproductive profiles among the chimpanzees of Mahale
Demography provides critical data to increase our understanding of the evolution, ecology, and conservation of primate populations. The chimpanzees of the Mahale Mountains National Park, Tanzania, have been studied for more than 34 yr on the basis of individual identification and standardized attendance records. From this long‐term study, we derived the following demographic data: The major cause of death was disease (48%), followed by senescence…

Descriptive epidemiology of fatal respiratory outbreaks and detection of a human‐related metapneumovirus in wild chimpanzees ( Pan troglodytes ) at Mahale Mountains National Park, Western Tanzania
Over the past several years, acute and fatal respiratory illnesses have occurred in the habituated group of wild chimpanzees at the Mahale Mountains National Park, Tanzania. Common respiratory viruses, such as measles and influenza, have been considered possible causative agents; however, neither of these viruses had been detected. During the fatal respiratory illnesses in 2003, 2005 and 2006, regular observations on affected individuals were rec…
