how dangerous are chimpanzees

[154] Trials already under way were however allowed to run their course. In addition, 19% of feeding time was spent on arboreal leaves, mostly Broussonetia papyrifera and Celtis mildbraedii. [40] According to Japan's Asahiyama Zoo, the grip strength of an adult chimpanzee is estimated to be 200 kg (441 lb),[41] while other sources claim figures of up to 330 kg (727 lb). [28] Wild adult males weigh between 40–70 kg (88–154 lb)[29][30][31] with females weighing between 27–50 kg (60–110 lb). Chimpanzees in the wild lead complex social lives; They form tribes, they make friends, they break up with friends. [107], Chimpanzees display numerous signs of intelligence, from the ability to remember symbols[109] to cooperation,[110] tool use,[111] and perhaps language. The feet are adapted for grasping, the big toe being opposable. Chimpanzees mate throughout the year and their pregnancy is similar to that of the human species. Animal testing on non-human primates § Chimpanzees in the U.S. One Small Step: The Story of the Space Chimps, "Going the whole orang: Darwin, Wallace and the natural history of orangutans", "A molecular phylogeny of the hominoid primates as indicated by two-dimensional protein electrophoresis", "Divergence population genetics of chimpanzees", "Evidence for a complex demographic history of chimpanzees", "Chimpanzee genomic diversity reveals ancient admixture with bonobos", "Chimps Belong on Human Branch of Family Tree, Study Says", "Pan troglodytes ssp. Some 12 chimpanzees are currently held at the facility. [100] A captive study suggests males can safely immigrate to a new group if accompanied by immigrant females who have an existing relationship with this male. . It prefers fruit above all other food items but also eats leaves and leaf buds, seeds, blossoms, stems, pith, bark and resin. %%EOF [147] Research chimpanzees tend to be used repeatedly over decades for up to 40 years, unlike the pattern of use of most laboratory animals. Arboreal locomotion consists of vertical climbing and brachiation. Blog are chimpanzees dangerous. [149] Five hundred chimps have been retired from laboratory use in the U.S. and live in animal sanctuaries in the U.S. or Canada. [90][84] While it was traditionally accepted that only female chimpanzees immigrate and males remain in their natal troop for life, there are confirmed cases of adult males safely integrating themselves into new communities among West African chimpanzees, suggesting they are less territorial than other subspecies. Chimpanzees in the wild lead complex social lives; They form tribes, they make friends, they break up with friends. [115], A 30-year study at Kyoto University's Primate Research Institute has shown that chimps are able to learn to recognise the numbers 1 to 9 and their values. While chimpanzees, gorillas and bonobos might not form a large part of the trade, their biology and ecology mean that they are disproportionately affected by the threat of hunting. [61][51], Chimpanzees do not appear to directly compete with gorillas in areas where they overlap. [3], "Chimp" redirects here. Afterward, they avoided the spot where the elder died and behaved in a more subdued manner. [172], The biggest threats to the chimpanzee are habitat destruction, poaching, and disease. [4] It is derived from Vili ci-mpenze[5] or Tshiluba language chimpenze, with a meaning of "ape". There are other problems: constant messes, demanding feeding schedule and the natural need chimpanzees have for mental stimulation. Chimpanzees can be very dangerous if they decide to attack someone. An adult chimpanzee is about twice a strong as a human. [67] Chimps may react to a leopard's presence with loud vocalising, branch shaking and throwing objects. [104], Vocalisations are also important in chimp communication. [80] There is also at least one recorded case of females securing a dominant position over males in their respective troop, albeit in a captive environment. When fruit is abundant gorilla and chimp diets converge, but when fruit is scarce gorillas resort to vegetation. But also, let's say we don't get along and we get in a fight instead. Farmers sometimes kill chimpanzees that threaten their crops; others are unintentionally maimed or killed by snares meant for other animals. [65] The oldest known captive chimp to have been documented lived to 66 years. Note: info to answer this is throughout the movie. h�bbd```b``Z"C�d$�d��d. The Common Chimpanzee is the more common and more vicious of the two. [85] Females in Taï have also been recorded to form alliances. The most common call in adults is the "pant-hoot", which may signal social rank and bond as well keep groups together. They know how to comfort one another, to fight, to steal, to beg, to tease, to intimidate, and to submit. [149][151], Other researchers argue that chimps either should not be used in research, or should be treated differently, for instance with legal status as persons. [132] Ant dipping is difficult and some chimps never master it. Chimpanzees can live up to 35 years in the wild, but females may only give birth once every five years. In this regard, chimpanzees share more in... See full answer below. Here at Save the Chimps, we are able to obtain nutritious food items year-round to provide three balanced meals per day. The chimps further show an aptitude for photographic memory, demonstrated in experiments in which the jumbled digits are flashed onto a computer screen for less than a quarter of a second. Some hundreds have been kept in laboratories for research, especially in America. [155], Chimpanzees including the female Ai have been studied at the Primate Research Institute of Kyoto University, Japan, formerly directed by Tetsuro Matsuzawa, since 1978. This is due to the differences in environmental and dietary adaptations; human internal parasite species overlap more with omnivorous, savanna-dwelling baboons. Stories have been told of chimps kidnapping and raping women. [117], Chimpanzees have displayed different behaviours in response to a dying or dead group member. They are also taken, often illegally, for the pet trade, and are hunted for medicinal purposes in some areas. Since the early reports on Washoe, numerous other studies have been conducted, with varying levels of success. This allows them to easily corner the monkeys when chasing them in the appropriate direction. This was evident after the attack and near death of former NASCAR driver St. James Davis, who was mauled by two escaped chimps while he and his wife were celebrating the birthday of their former pet chimp. [47] At Bossou, the chimpanzee inhabits multistage secondary deciduous forest, which has grown after shifting cultivation, as well as primary forest and grassland. They are especially suited for the latter role on account of their prominent facial features, long limbs and fast movements, which humans often find amusing. It normally lasts around 8 months. Chimpanzees are legally protected in most of their range, and are found both in and outside national parks. One suggestion is that drones, camera traps and remote microphones should be used to record and monitor chimpanzees rather than direct observation. Finally, "ambushers" hide and rush out when a monkey nears. [135], Scientists have attempted to teach human language to several species of great ape. During the adolescence stage which is about six or seven the chimps are no longer cute and fun but a bundle of raging testosterone. "Chasers" move quickly and try to make a catch. Chimps may also express themselves with the "pout", which is made in distress, the "sneer", which is made when threatening or fearful, and "compressed-lips face", which is a type of display. [70] Four chimpanzees could have fallen prey to lions at Mahale Mountains National Park. When witnessing a sudden death, the other group members act in frenzy, with vocalisations, aggressive displays, and touching of the corpse. National Geographic is reporting violent [146], A five-year moratorium was imposed by the US National Institutes of Health in 1996, because too many chimps had been bred for HIV research, and it has been extended annually since 2001. Unable to reason in the... See full answer below. Chimpanzees and all other nonhuman primates have only the working version; in other words, they’re on the powerful, “sprinter” end of the spectrum. Other mammalian prey include red-tailed monkeys, infant and juvenile yellow baboons, bush babies, blue duikers, bushbucks, and common warthogs. [105][85] Whimpering is made by young chimps as a form of begging or when lost from the group. The masks may also serve to guard households and protect both human and plant fertility. Males remain in their natal communities, while females generally emigrate at adolescence. [82] Being in a coalition allows males to dominate a third individual when they could not by themselves, as politically apt chimps can exert power over aggressive interactions regardless of their rank. Chimps may react to lions by fleeing up trees, vocalising or hiding in silence. [111] When foraging for honey, chimps use modified short sticks to scoop the honey out of the hive, that is, if the bees are stingless. Nevertheless, the status of an adult female may be important for her offspring. Though they may be docile at a very young age, they usually grow up to become aggressive wild animals. Chimpanzees can be very dangerous if they decide to attack someone. [83], Chimpanzees have been described as highly territorial and will frequently kill other chimps,[87] although Margaret Power wrote in her 1991 book The Egalitarians that the field studies from which the aggressive data came, Gombe and Mahale, used artificial feeding systems that increased aggression in the chimpanzee populations studied, and might not reflect innate characteristics of the species as a whole as such. It lives in a variety of habitats, including dry savanna, evergreen rainforest, montane forest, swamp forest and dry woodland-savanna mosaic. Chimps may also hunt as a coordinated team, so that they can corner their prey even in a continuous canopy. Chimpanzees in the wild lead complex social lives; They form tribes, they make friends, they break up with friends. For the … Nearly all chimpanzee populations have been recorded using tools, modifying sticks, rocks, grass and leaves and using them for hunting and acquiring honey, termites, ants, nuts and water. National Geographic is reporting violent chimpanzees are becoming a very dangerous problem for some locals in Uganda. It formerly held 108 chimpanzees among 1,300 non-human primates. How did Darwin know that the mountains rose from the sea? Chimpanzees are between 3 feet 3 inches and 5 feet 6 inches (1 to 1.7 meters) tall when standing upright like a … [39] The physical strength of chimps is around 1.5 times greater than humans, due to higher content of fast twitch muscle fibres, one of the chimpanzee's adaptations for climbing and swinging. The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. Most such laboratories either conduct or make the animals available for invasive research,[146] defined as "inoculation with an infectious agent, surgery or biopsy conducted for the sake of research and not for the sake of the chimpanzee, and/or drug testing". Keep in mind that I'll be nice to it. Low-ranking males benefit from an unstable hierarchy and often find increased sexual opportunities if a dispute or conflict occurs. The biggest threats to the chimpanzee are habitat loss, poaching, and disease. Chimpanzees Intentionally Warn Their Friends About Danger A new study shows that the apes make specific warning calls when near other chimps, and … The enjoyment of tickling in chimpanzees does not diminish with age. The most prevalent species was the protozoan Troglodytella abrassarti. The reason we have them behind bars in zoos and research settings is because chimpanzees can be very dangerous—it's to protect ourselves. In one case chimps cared for a dying elder, then attended and cleaned the corpse. Darwin’s Dangerous Idea. Chimpanzee habitats have been limited by deforestation in both West and Central Africa. [b], The chimpanzee is a highly adaptable species. A Chimpanzee Genome Project was initiated after the completion of the Human Genome Project. Because no species other than Homo sapiens has survived from the human line of that branching, both chimpanzee species are the closest living relatives of humans; the lineage of humans and chimpanzees diverged from gorillas (genus Gorilla) about seven million years ago. 1. They succumb to many diseases that afflict humans, because the two species are so similar. One chimp, Ayumu, was able to correctly and quickly point to the positions where they appeared in ascending order. June 26, 2017 — For years, anecdotes and some studies have suggested that chimpanzees are 'super strong' compared to humans, implying that their muscle fibers are … He told National Geographic: "I don't think we should make a distinction between our obligation to treat humanely any species, whether it's a rat or a monkey or a chimpanzee. In the reanalysis, Terrace and Bever concluded that Nim's utterances could be explained merely as prompting on the part of the experimenters, as well as mistakes in reporting the data. )mi��AUQ��g�%�Ҏ�Ԓ��B:��jmǥ:�/�.��[�-�h��%��#d��F�Ȧ>�s�|Lq�duA�K��"�._\��|Z[�_��x��{U&t��bȅp1��RzJ\v ��~ ��6�V׉�jV��*p��U fT0��Y�M� [104] Chimps use distance calls to draw attention to danger, food sources, or other community members. Chimps are promiscuous; during oestrus, females mate with several males in their community, while males have large testicles for sperm competition. They are sometimes kept as pets, though their strength and aggressiveness makes them dangerous in this role. Advertisement However, in all cases, the majority of their diet consists of fruits, leaves, roots, and other plant matter. Wolfgang Köhler, for instance, reported insightful behaviour in chimpanzees, but he likewise often observed that they experienced "special difficulty" in solving simple problems. "Chimp survives 420-mile ride into space", "Next of Kin: A Report on the Use of Primates in Experiments", "Building an inner sanctuary: complex PTSD in chimpanzees", "Europe brings experiments on chimpanzees to an end", "Lab chimps face housing crisis: Experiments on apes end, but problems remain", "Texas man saves friend during fatal chimp attack", "Chimp attack kills cabbie and injures tourists", "Online Extra: Frodo @ National Geographic Magazine", "Birthday party turns bloody when chimps attack", "911 tape captures chimpanzee owner's horror as 200-pound ape mauls friend", "Chimp attack 911 call: 'He's ripping her apart, "Chimpanzee reservoirs of pandemic and nonpandemic HIV-1", U.S. Cultural Intelligence It is generally accepted that chimpanzees possess culture, in the sense of acquired information being passed down the generations and shared with other members of an animal's social grouping. Unlike domesticated animals, such as cats and dogs, chimps are wild animals and they need to … Why was, and still may be, Darwin’s idea of evolution dangerous? When they reach two years of age, they are able to move and sit independently, and start moving beyond the arms reach of their mothers. [107] While both adults and infants are taken, adult male colobus monkeys will attack the hunting chimps. & Sommer, V.", "Pan troglodytes ssp. [141][142] Animal rights groups have urged a stop to such acts, considering them abusive. Captive chimps tend to live longer, with median lifespans of 31.7 years for males and 38.7 years for females. The skin may range from pale to dark, and females develop swelling pink skin when in oestrus. [145], Hundreds of chimpanzees have been kept in laboratories for research. All three are tremendously strong and that alone makes all of them potentially dangerous, but chimpanzees are by far the most likely to come unglued for literally no reason whatsoever. [111] Chimpanzees have used stone tools since at least 4,300 years ago. [75], Male chimpanzees exist in a linear dominance hierarchy. Never mind that it's illegal to keep chimps as pets in most of the US, it's also incredibly foolish. Chimpanzee laughter is not readily recognisable to humans as such, because it is generated by alternating inhalations and exhalations that sound more like breathing and panting. [149] With the publication of the chimpanzee genome, plans to increase the use of chimps in America were reportedly increasing in 2006, some scientists arguing that the federal moratorium on breeding chimps for research should be lifted. I love chimpanzees and I want to make friends with one someday. As such, males in a community are more likely to be related to one another than females are to each other. [88], Chimpanzees have attacked humans. Darwin’s Dangerous Idea Did Darwin’s idea of evolution go against common beliefs? [67][68] It is possible that much of the mortality caused by leopards can be attributed to individuals that have specialised in chimp-killing. They are hunted for their meat, which is seen as a delicacy for the wealthy in Central Africa. It has four confirmed subspecies and a fifth proposed subspecies. Nut cracking is also difficult and must be learned. An adult chimpanzee is about twice a strong as a human. h��W]N�H�w�wh��P��nw[��ϐ�ey0I܀+p��8'��j�!�XX�q��g��6�iW2/`�p��g�� q�㾫��k�뒹�t��+h��|l5s��V� ��97]X2�Q��4�̕��|��h�۾��z��~��_��b��I��O�`k{�qh] ,�g�ff��g\��Y�;I7��a/�kqM�KQ�gF&��"�@B1\��a�1Ѕc��{-�8c� What are the chances that I get seriously injured or killed if I'm alone in a room with it? troglodytes: Maisels, F., Strindberg, S., Greer, D., Jeffery, K., Morgan, D.L. [a], The chimpanzee is more robustly built than the bonobo but less than the gorilla. [164], A chimpanzee's strength and sharp teeth mean that attacks, even on adult humans, can cause severe injuries. What is REALLY dangerous is interacting with any animal if you don't understand how the animal behaves and, how it will react to your behavior. But aren't they supposed to be many times stronger than any human? [163] At least six cases of chimpanzees snatching and eating human babies are documented. They also do this when encountering individuals from other communities. Existing chimpanzee populations in West and Central Africa do not overlap with the major human fossil sites in East Africa, but chimpanzee fossils have now been reported from Kenya. [167][168], Two types of human immunodeficiency virus (HIV) infect humans: HIV-1 and HIV-2. Note: info to answer this is throughout the movie. [52][53] A study in Budongo Forest, Uganda found that 64.5% of their chimp feeding time concentrated on fruits (84.6% of which being ripe), particularly those from two species of Ficus, Maesopsis eminii and Celtis durandii. [132][111] Some forethought in this activity is apparent, as these tools are not found together or where the nuts are collected. But chimps in the wild are not used to people—they're afraid of them. [13], DNA evidence suggests the bonobo and chimpanzee species separated from each other less than one million years ago (similar in relation between Homo sapiens and Neanderthals). HIV-2 crossed species from a different strain of HIV, found in the sooty mangabey monkeys in Guinea-Bissau. [69][67] There is at least one record of chimps killing a leopard cub, after mobbing it and its mother in their den. Humans and chimpanzees share similar ticklish areas of the body, such as the armpits and belly. [66], Leopards prey on chimpanzees in some areas. The 1972 film Conquest of the Planet of the Apes, the third sequel of the 1968 film Planet of the Apes, portrays a futuristic revolt of enslaved apes led by the only talking chimpanzee, Caesar, against their human masters. They remain in continual contact for the rest of their first year. The more allies a male has, the better his chance of becoming dominant. Infant chimpanzees normally receive 24-hour attention from their mothers. 35 0 obj <>/Filter/FlateDecode/ID[<188E92D23060F8BD92CA349D6850A53B><561A876380CF474C81AE9B9C1DED0972>]/Index[18 33]/Info 17 0 R/Length 91/Prev 152494/Root 19 0 R/Size 51/Type/XRef/W[1 3 1]>>stream The pelvis is long with an extended ilium. [91], Chimpanzees mate throughout the year, although the number of females in oestrus varies seasonally in a group. [75], At the core of social structures are males, which patrol the territory, protect group members, and search for food. In Uncategorized by April 2, 2021 0 Comments Uncategorized by April 2, 2021 0 Comments Chimpanzee violent attacks are on the rise. A study published in 2010 found that the chimpanzees' wage wars over territory, not mates. [156], Jane Goodall undertook the first long-term field study of the chimpanzee, begun in Tanzania at Gombe Stream National Park in 1960. `1��>��t�;��h��#J:��r +��8eV�8�ד��3��=�+Q�x�s��؉�p`��/�Z\$�kY؏:��o��X�Tm�sG�0KF�_\\H�32��Y�N�Ξ�Ҍ"��W]R%$�/ai �9>��p��N��r&}�\�0͕�KG�V`%XM��JL�p��(/�2��@ZP�5�s�釃�m�l��i�iT�]�� tB��a~��)S�s��ݗR8�Ô��i�ݠ��-��w��K�Wў�3A��A�m��wSJ3c�vNٗT歇��~n�ck��Q�B��z��Q�(�:��/�.\@:�`"�C3��.l��)�fu�~�7��Q��Ρ��D��Lh�.2a��~��.�(��If�G}�4��Q/��H��+�S�[a�3;��6��7��k�N��|)�↽�T��"�&�jW�i*nX&gr�I@��MҔ��5%�R��R�X�Ү� *aܕ��TUP��L��ϊo*BV!�Q�t��i�x�{(=W�|>p�h��a�T�� [88] In the years following her artificial feeding conditions at Gombe, Jane Goodall described groups of male chimps patrolling the borders of their territory, brutally attacking chimps which had split off from the Gombe group. endstream endobj startxref Oestrous females exhibit sexual swellings. No other organization is as closely aligned to the work of understanding and protecting chimpanzees as the Jane Goodall Institute. "Drivers" serve to keep the prey running in a certain direction and follow them without attempting to make a catch. Chimpanzees can feel empathy for others. Although deforestation rates are low in western Central Africa, selective logging may take place outside national parks. Depictions of chimpanzees as individuals rather than stock characters, and as central rather than incidental to the plot can be found in science fiction. [137], Debate is ongoing among scientists such as David Premack about chimpanzees' ability to learn language. The Dutch ministry of science decided to phase out research at the centre from 2001. [165][166] Another example of chimpanzees being aggressive toward humans occurred in 2009 in Stamford, Connecticut, when a 90-kilogram (200 lb), 13-year-old pet chimp named Travis attacked his owner's friend, who lost her hands, eyes, nose, and part of her maxilla from the attack. Typically, males will kill and eat the infant of another female, usually in their own group but occasionally in another. Chimpanzees appear in Western popular culture as stereotyped clown-figures, and have featured in entertainments such as chimpanzees' tea parties, circus acts and stage shows. [7] The genus name Pan derives from the Greek god, while the specific name troglodytes was taken from the Troglodytae, a mythical race of cave-dwellers. [53][59] Female chimpanzees appear to consume much less animal flesh than males, according to several studies. [153] Stuart Zola, director of the Yerkes laboratory, disagrees.

Adolescent males spend time with adult males in social activities like hunting and boundary patrolling. schweinfurthii: Plumptre, A., Hart, J.A., Hicks, T.C., Nixon, S., Piel, A.K. [116], Great apes show laughter-like vocalisations in response to physical contact, such as wrestling, play chasing, or tickling. [17], Four subspecies of the chimpanzee have been recognised,[18][19] with the possibility of a fifth:[16][20], Human and chimpanzee DNA is very similar. ��) Coalitions can also give an individual male the confidence to challenge a dominant or larger male. [169], The chimpanzee is listed on the IUCN Red List as an endangered species. The hands have long fingers with short thumbs and flat fingernails. What is REALLY dangerous is interacting with any animal if you don't understand how the animal behaves and, how it will react to your behavior. [92] Female chimps are more likely to come into oestrus when food is readily available. There are four subpopulations of the chimpanzee — the western chimp, the Nigeria-Cameroon chimp, the central chimp, and the eastern chimp. [58], Despite the fact that chimpanzees are known to hunt, and to collect insects and other invertebrates, such food actually makes up a very small portion of their diet, from as little as 2% yearly to as much as 65 grams of animal flesh per day for each adult chimpanzee in peak hunting seasons. Nim never initiated conversations himself, rarely introduced new words, and mostly imitated what the humans did. Chimpanzees are genetically closest to humans, and in fact, chimpanzees share about 98.6% of our DNA. They can attack and when they do so they will bite with fierce canine teeth which exert 20 times more force when biting than a human. [84], Low-ranking males frequently switch sides in disputes between more dominant individuals. Juveniles remain close to their mothers, but interact an increasing amount with other members of their community. What is REALLY dangerous is interacting with any animal if you don't understand how the animal behaves and, how it will react to your behavior. In Virunga National Park in the east of the country, the park authorities regularly confiscate chimpanzees from people keeping them as pets. [104] Submissive individuals make "pant-grunts" towards their superiors. [72] A 2017 study of gastrointestinal parasites of wild chimps in degraded forest in Uganda found nine species of protozoa, five nematodes, one cestode, and one trematode. This indicates that both humans and members of the Pan clade were present in the East African Rift Valley during the Middle Pleistocene. These are among the largest monkeys as well as one of the most dangerous monkeys to avoid. ANSWER: The reason we have them behind bars in zoos and research settings is because chimpanzees can be very dangerous—it's to protect ourselves. [35] As a result, individual chimpanzees often forage for food alone, or in smaller groups as opposed to the much larger "parent" group, which encompasses all the chimpanzees which regularly come into contact and congregate into parties in a particular area. [78][83] Chimpanzee alliances can be very fickle and one member may suddenly turn on another if it is to his advantage. Both males and females sometimes travel alone. We also both play, have complex emotions and intelligence, and a very similar physical makeup. Between 172,700 and 299,700 individuals are thought to be living in the wild,[3] a decrease from about a million chimpanzees in the early 1900s. No human can approach this level of caretaking. For their first 30 days, infants cling to their mother's bellies. [35] Care for the young is provided mostly by their mothers. endstream endobj 19 0 obj <> endobj 20 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/XObject<>>>/Rotate 0/Type/Page>> endobj 21 0 obj <>stream [8][9][11], Despite a large number of Homo fossil finds, Pan fossils were not described until 2005. h�b```g``re`a`��d�c@ >f�(G�B�)��?ptpt��@��\��X ,� HW��1�0|g�c��èǨ��(_/��s@Ut/�dn�> �D In fact, chimpanzees are our closest cousins; we share about 98% of our genes. [50] The chimpanzee makes a night nest in a tree in a new location every night, with every chimpanzee in a separate nest other than infants or juvenile chimpanzees, which sleep with their mothers. "Much of the apes' behavior is pure drill", he said. The chimps eat tropical fruits and vegetables bought from local farmers, and sleep in large night cages for protection from poachers. & Pintea, L.", "Initial sequence of the chimpanzee genome and comparison with the human genome", "Bipedal tool use strengthens chimpanzee hand preferences", "Inhibition of endotoxin-induced activation of coagulation and fibrinolysis by pentoxifylline or by a monoclonal anti-tissue factor antibody in chimpanzees", "Independent evolution of knuckle-walking in African apes shows that humans did not evolve from a knuckle-walking ancestor", "Chimpanzee super strength and human skeletal muscle evolution", The Chimpanzee: A Topical Bibliography, Second Edition, "The Tai Chimpanzee Project in Cote d'Ivoire, West Africa", "Feeding ecology of chimpanzees in the Kibale Forest, Uganda", "The Predatory Behavior and Ecology of Wild Chimpanzees", "Africa's Oldest Chimp, a Conservation Icon, Dies", "An Encounter between a leopard and a group of chimpanzees at Gombe National Park", "Gastrointestinal parasite infections and self-medication in wild chimpanzees surviving in degraded forest fragments within an agricultural landscape mosaic in Uganda", "Variation in hunting behaviour in neighbouring chimpanzee communities in the Budongo forest, Uganda", "Agonistic behavior, dominance, and social structure in wild chimpanzees of the Gombe National Park", "The Rise and Fall of a Chimpanzee Matriarchy - Przekrój Magazine", "Reciprocity and interchange in the social relationships of wild male chimpanzees", "Chimpanzee females queue but males compete for social status", "Trade-offs in the production of animal vocal sequences: insights from the structure of wild chimpanzee pant hoots", "How chimpanzees cooperate in a competitive world", "Behavioural Diversity among the Wild Chimpanzee Populations of Bossou and Neighbouring Areas, Guinea and Côte d'Ivoire, West Africa", "Pestle-pounding and nut-cracking by wild chimpanzees at Kpala, Liberia", "Chimpanzees using stones to crack open oil palm nuts in Liberia", "Chimpanzees (Pan troglodytes) and the question of cumulative culture: an experimental approach", "Complex tool sets for honey extraction among chimpanzees in Loango National Park, Gabon", "Chimpanzees routinely fish for algae with tools during the dry season in Bakoun, Guinea", "4,300-year-old chimpanzee sites and the origins of percussive stone technology", "Female Chimps Seen Making, Wielding Spears", "PG Tips chimps: The last of the tea-advertising apes", "Chimpanzee Research: Overview of Research Uses and Costs".
