Governor of Aceh who signed palm oil permit: plantation in Tripa "morally wrong"
(04/05/2012) The former governor of Aceh, Irwandi Yusuf, told The Sydney Morning Herald today that an oil palm plantation he approved was "not wrong legally, but wrong morally." Irwandi, who is currently seeking re-election, signed off on the hugely controversial plantation in deep peat forest last August, but the issue came to a head this week as satellite images showed a dozen fires burning in the concession area known as Tripa. Environmental groups, which are running an online campaign, warn that the burning is imperiling an important population of Critically Endangered Sumatran orangutans (Pongo abelii).
Featured video: the battle for Tripa is about people too
(04/05/2012) Environmentalists have largely focused on the plight of orangutans as fires burn in Aceh, Sumatra to clear rainforest for a hugely controversial palm oil plantation, however as the video above highlights, local people will also feel the impacts of the destruction of forest for palm oil.
Beyond Bigfoot: the science of cryptozoology
(03/26/2012) Anyone who doubts cryptozoology, which in Greek means the "study of hidden animals," should remember the many lessons of the past 110 years: the mountain gorilla (discovered in 1902), the colossal squid (discovered in 1925, but a full specimen not caught until 1981), and the saola (discovered in 1992) to name a few. Every year, almost 20,000 new species are described by the world's scientists, and a new book by Dr. Karl Shuker, The Encycloapedia of New and Rediscovered Animals, highlights some of the most incredible and notable new animals uncovered during the past century.
Chimp conservation requires protecting fragmented river forests in Uganda
(03/19/2012) Forest fragments along riversides in Uganda may make good habitats for chimpanzees but remain unprotected, according to a new study in mongabay.com's open access journal Tropical Conservation Society (TCS). Researchers surveyed a riverine forest known as Bulindi in Uganda, in-between Budongo and Bugoma Forest Reserves, to determine if it was suitable for the long-term survival of eastern chimpanzee (Pan troglodytes schweinfurthii) populations.
Oil exploration approved in Africa's oldest park, Virunga National Park
(03/19/2012) Permits for controversial oil exploration in Virunga National Park have been released after request by NGO Global Witness. Oil company, SOCO International, has confirmed it has received two permits to undertake preliminary exploration, including seismic tests, in the UNESCO World Heritage Site. Located in the Democratic Republic of Congo (DRC), Virunga is famous for its population of the Critically Endangered mountain gorillas (Gorilla beringei beringei).
Without data, fate of great apes unknown
(03/12/2012) Our closest nonhuman relatives, the great apes, are in mortal danger. Every one of the six great ape species is endangered, and without more effective conservation measures, they may be extinct in the wild within a human generation. The four African great ape species (bonobos, chimpanzees and two species of gorilla) inhabit a broad swath of land across the middle of Africa, and two species of orangutans live in rainforests on the islands of Borneo and Sumatra in Southeast Asia.
Investigation links APP to illegal logging of protected trees
(03/01/2012) A year-long undercover investigation has found evidence of Asia Pulp and Paper (APP) companies cutting and pulping legally protected ramin trees, a practice that violates both Indonesian and international law. Found largely in Sumatra's peatswamp forests, the logging of ramin trees (in the genus Gonystylus) has been banned in Indonesia since 2001; the trees are also listed under Appendix II of the Convention on International Trade in Endangered Species (CITES) and thus require special permits to export. The new allegations come after APP, an umbrella paper brand, has lost several customers due to its continued reliance on pulp from rainforest and peatland forests in Sumatra.
Busted: orangutan trafficker prosecuted and sent to prison in Sumatra for the first time
(02/23/2012) For the first time in Medan, North Sumatra, an orangutan trader has been prosecuted and sent to prison for trafficking in the endangered apes, reports the Wildlife Conservation Society (WCS).
Wild orangutans to watch film about orangutans
(02/22/2012) Born to be Wild 3D, an IMAX documentary in part about the plight of orphaned and injured Bornean orangutans (Pongo pygmaeus), will soon be aired in the rainforest that inspired it. Producer Drew Fellman is setting up a screen in the rainforest to screen the film for orphaned orangutans. "They came to be like members of the crew," Fellman told the Associated Press.
Republic of the Congo expands park to protect fearless chimps
(02/16/2012) The Republic of the Congo has expanded its Nouabalé-Ndoki National Park by 37,295 hectares (144 square miles) to include a dense swamp forest, home to a population of chimpanzees (Pan troglodytes) that show no fear of humans. Known as the Goualougo Triangle, the swamp forest is also home to forest elephants (Loxodonta cyclotis) and western lowland gorillas (Gorilla gorilla gorilla). The expansion of the park to include the Goualougo Triangle makes good on a government commitment from 2001.
The camera trap revolution: how a simple device is shaping research and conservation worldwide
(02/14/2012) I must confess to a recent addiction: camera trap photos. When the Smithsonian released 202,000 camera trap photos to the public online, I couldn’t help but spend hours transfixed by the private world of animals. There was the golden snub-monkey (Rhinopithecus roxellana), with its unmistakably blue face staring straight at you, captured on a trail in the mountains of China. Or a southern tamandua (Tamandua tetradactyla), a tree anteater that resembles a living Muppet, poking its nose in the leaf litter as sunlight plays on its head in the Peruvian Amazon. Or the dim body of a spotted hyena (Crocuta crocuta) led by jewel-like eyes in the Tanzanian night. Or the less exotic red fox (Vulpes vulpes) which admittedly appears much more exotic when shot in China in the midst of a snowstorm. Even the giant panda (Ailuropoda melanoleuca), an animal I too often connect with cartoons and stuffed animals, looks wholly real and wild when captured by camera trap: no longer a symbol or even a pudgy bear at the zoo, but a true animal with its own inner, mysterious life.
Price of gorilla permit increases to $750/day
(02/05/2012) Rwanda has raised the price of a permit to see mountain gorillas to $750 per day starting June 1, 2012, up from $500.
Featured video: plight of orangutans highlighted with new rock song
(01/17/2012) An Indonesian rock band, Navicula, is highlighting the plight of orangutans in their native country through a new song entitled, aptly, "Orangutan." The band has created a music video for the song, including footage of a documentary, Green: The Film that follows a starving female orangutan named Green. The band "dedicated the song to encourage people to do more in orangutan conservation, to protect this endangered species."
Palm oil, pulp companies commit to zero-tolerance policy for orangutan killing
(12/06/2011) Two Indonesian plantation companies have signed an agreement to train workers not to kill or injure orangutans and other protected species. The agreement was brokered by the Indonesian government between Orangutan Foundation International (OFI), a non-profit with operations in Central Kalimantan, Indonesian Borneo, and two major plantation firms: PT Smart, one of Indonesia's largest palm oil producers, and PT Lontar Papyrus, which supplies wood-pulp to Asia Pulp & Paper (APP). Both companies are holdings of the Sinar Mas Group. Under the terms of the deal, OFI will assist the companies 'in delivering a best management practices training program on orangutans and endangered species for its employees, affiliates and pulpwood suppliers.'
World's most endangered primate still losing habitat
(12/04/2011) Just twenty-three Hainan gibbons (Nomascus hainanus) survive in the world. Confined to a single protected area on a lone island, Hainan gibbons are losing their habitat at a steady rate of 20 hectares per day finds a new study by Greenpeace. In all, nearly a quarter of the Critically Endangered lesser ape's habitat has been lost since 2001.
Eat like an orangutan to save rainforests
(11/30/2011) One doesn't have to be a scientist or a government official to help save the world's vanishing rainforests, one can also be a chef. World-renowned chef Andre Chiang has added a new item to his menu called Orangutan Salad, reports the Wall Street Journal, which he hopes will raise awareness for the endangered apes at his Singapore eatery, Restaurant Andre. The new salad gives restaurant-goers the chance to enjoy all the subtle, earthy tastes of a typical orangutan meal, including ferns, tree fungi, figs, berries, orchid leaves, and durian flowers.
Rare apes saved in India
(11/30/2011) Two Hoolock gibbons have been successfully translocated from a fragmented forest to Mehao Wildlife Sanctuary in the beginning of a desperate bid to save 18 family groups of India's last apes. Living near the village of Dello in northeastern India, the apes were straining to survive amid heavy deforestation and fragmentation.
Entertainment media skews public perception of chimpanzees in the wild
(11/14/2011) You've probably seen them: the TV ads showing chimpanzees wearing suits, driving cars, or smoking cigars. These ads may tickle our funny bone, but they warp our perceptions of how chimpanzees are faring in the wild, researchers at Duke University have found. The study, published October 12 in the journal PLoS ONE, examined whether watching commercials featuring chimpanzees influenced people's understanding of their endangered status.
Orangutans in Indonesian Borneo doomed to extinction?
(11/14/2011) A new study finds orangutans in Indonesian Borneo in unprotected areas are being killed at a rate faster than what population viability analysis considers sustainable. Conflict between orangutans and humans is worst in areas that have been fragmented and converted for timber, wood-pulp, and palm oil production, but hunting is occurring in relatively intact forest zones away from industrial development.
If camera traps don't prove existence of Bigfoot or Yeti nothing will
(10/13/2011) Let me state for the record that I am skeptical of the existence of Bigfoot or the Yeti, however I do have a fascination for following the latest news on the seemingly never-ending search for these hidden hominids. This week a Yeti conference in Russia announced 'indisputable proof' of the legendary hairy ape in the wilds of Southern Siberia. What did this proof consist of? Not DNA, photographs, video, or the Yeti itself (dead or alive) as one would expect from the word 'indisputable', but a few alleged Yeti hairs, an alleged bed, and alleged footprints. Cryptozoologists, those who are fascinated by hidden species such as the proposed Yeti and Bigfoot, don't serve their cause by stating the reality of a species without the evidence long-deemed necessary by scientific community to prove it—either a body or DNA samples combined with clear photographic evidence—instead they make themselves easy targets of scorn and ridicule.
'Indisputable proof' of Yeti discovered
(10/10/2011) A conference has announced that given recent evidence they are 95 percent convinced the yeti, a mythical or perhaps actual primate, exists in the cold wilds of Siberia. Scientists and cryptozoologists (those who have a fascination for the 'study of hidden species' such as Bigfoot) met in the Kemerovo region of Russia to exchange information on the yeti, also known as the Abominable Snowman, and to conduct fieldwork. According to a statement from the conference, members found new evidence of the yeti's cryptic existence.
Gorilla poachers brutally murder forest ranger
(10/09/2011) Forest ranger, Zomedel Pierre Achille, was brutally murdered by gorilla poachers near Lobéké National Park in Cameroon, according to the World Wide Fund for Nature (WWF).
New US stamp seeks to raise money for endangered species
(09/20/2011) As of today, buying a stamp may help save some of the world's most beloved and endangered species. The US Postal Service has released a new stamp that will raise money for the Multinational Species Conservation Funds (MSCF) which works to save tigers, rhinos, great apes, marine turtles, and elephants. The new stamp sports the image of an Amur tiger cub, a subspecies of the tiger the Amur tiger (Panthera tigris altaica) is listed as Endangered by the IUCN Red List.
How fruit defines Borneo
(08/01/2011) Among conservationists and biologists, the mega-island of Borneo is a sort of Mecca. Its rich plant and animal biodiversity, as well as high degree of endemism (unique species found nowhere else) make it a naturalist's dream. There is one aspect of this biological richness which applies to the wellbeing and happiness of all of Borneo’s residents, human and animal, in a very direct way: fruit. From wild forest berries to juicy cultivated rambutans, fruit permeates the ecology, landscape and culture of Borneo. On the island there are over 70 wild fruit trees species and around 45 cultivated species that are consumed by people (1). Science has certainly not yet documented all the fruit consumed by wildlife, but we know that the total must be over 500 species.
Saving (and studying) one of Nigeria's last montane forests
(07/26/2011) Between 2000 and 2010, Nigeria lost nearly a third (31 percent) of its forest cover, while its primary forests suffered even worse: in just five years (2000 to 2005) over half of the nation's primary forests were destroyed, the highest rate in the world during that time. Yet, Nigeria's dwindling forests have never received the same attention as many other country's, such as Indonesia, Brazil, Malaysia, or Peru, even though in many ways Nigeria struggles with even deeper problems than other developing nations. Despite vast oil business, the nation is plagued by poverty and destitution, a prime example of what economists call the 'resource curse'. Environmentally, it has been named one of the worst in the world. Yet, not all forest news out of Nigeria is bleak: the success of the Nigerian Montane Forest Project in one of the country's remaining forests is one such beacon of hope, and one example of how the country could move forward.
WWF partnering with companies that destroy rainforests, threaten endangered species
(07/25/2011) Arguably the globe's most well-known conservation organization, the World Wide Fund for Nature (WWF), has been facilitating illegal logging, vast deforestation, and human rights abuses by pairing up with notorious logging companies in a flagging effort to convert them to greener practices, alleges a new report by Global Witness. Through its program, the Global Forest and Trade Network (GFTN), WWF—known as World Wildlife Fund in the US and Canada—has become entangled with some dubious companies, including one that is imperiling orangutans in Borneo and another which has been accused of human rights abuses in the Congo rainforest. Even with such infractions, these companies are still able to tout connections to WWF and use its popular panda logo. The Global Witness report, entitled Pandering to the Loggers, calls for WWF to make large-scale changes in order to save the credibility of its corporate program.
Hundreds of Critically Endangered apes found in remote Vietnam
(07/18/2011) A new population—hundreds strong—of northern white-cheeked crested gibbon (Nomascus leucogenys) has been found in Vietnam by researchers with Conservation International (CI). The group estimates that around 130 gibbon groups—455 individuals—survive in Pu Mat National Park, making it the only known viable population of this species in the world and effectively tripling the global populations. Unfortunately, these newly-discovered gibbons are imperiled by road-building through the park.
Conservationists seek $15M for rarest chimp
(06/27/2011) A new conservation plan calls for $14.6 million to save the world's rarest subspecies of chimp: the Nigeria-Cameroon chimpanzee, reports the Wildlife Conservation Scoeity (WCS).
Over 80 percent of urban Congolese eat bushmeat
(06/27/2011) Bushmeat is one of the major threats to wildlife in parts of Africa: large and medium-sized animals are vanishing from regions in a trend dubbed by biologists the 'empty forest syndrome'. A number of popularly consumed species are also threatened with global extinction. A new study in mongabay.com's open access journal Tropical Conservation Science surveyed 1,050 households in Brazzaville, the capital of Republic of the Congo, regarding their consumption of bushmeat only to find that the practice was practically universal: 88.3 percent of households in Brazzaville consumed bushmeat.

(04/15/2011) A population of the world's largest subspecies of gorilla has increased despite ongoing human conflict, reports the Wildlife Conservation Society (WCS).
Counting orangutans: the best way to survey the great apes
(03/28/2011) How do you count orangutans when they are difficult to spot in the wild given that they are shy, arboreal, and few and far between? To find a solution, biologists have turned to estimating orangutan populations by counting their nests, which the great apes make anew every night. In order to make the most accurate count possible, researchers have studied the different factors that could impact the success, or lack thereof, of nest-counters in mongabay.com's open access journal Tropical Conservation Science.
Elephants cooperate as well as chimps
(03/07/2011) A new study proves that elephants understand how sometimes two is better than one. Working with Asian elephants (Elephas maximus) at the Thai Elephant Conservation Center, researchers reconstructed a classic cooperation test that was originally developed for chimpanzees. Subjects must pull on a rope to receive a reward, such as food, however—and here's the crux—the treat is only released if two subjects cooperate by pulling on two different ropes simultaneously. The paper published in Proceedings of the National Academy of Sciences found that elephants were as capable of cooperation as chimpanzees.
Oil company charged after allegedly forcing entry into Virunga National Park
(02/21/2011) The Democratic Republic of Congo's (DRC) national parks authority, ICCN, has filed a suit against oil company, SOCO International, for allegedly forcing entry into Virunga National Park. The legal row comes amid revelations that two oil companies, SOCO and Dominion Petroleum, are exploring the park for oil.
Rehabilitated orangutans need guards in Borneo, says activist
(02/19/2011) 1,200 orangutans set for reintroduction into the wild in Indonesian Borneo will be immediately at risk from poaching and illegal logging, warned an orangutan welfare group.
UN and conservation organizations condemn big oil's plan to drill in Virunga National Park
(01/20/2011) WWF, the International Union for the Conservation of Nature (IUCN), and the UN have all recently expressed concerns about two oil companies' plan to explore for oil in Africa's oldest and famed Virunga National Park. Home to a quarter of the world's mountain gorillas, as well as chimpanzees, hippos, lions, forest elephants, and rare birds Virunga National Park in the Democratic Republic of Congo (DRC) is one of Africa's most biodiverse parks and is classified by the UN as a World Heritage Site. But according to WWF plans by oil companies SOCO International and Dominion Petroleum could jeopardize not only the wildlife and ecosystems, but also local people.
Teaching orangutans to be wild – orangutan rehabilitation
(12/15/2010) Michelle Desilets, Executive Director of the Orangutan Land Trust, spoke with Laurel Neme on her 'The WildLife' radio show and podcast about the process of rehabilitating orphaned orangutans and teaching them to be wild. This is the second in a two-part interview. The first part covered orangutan biology, habits and the interconnected threats, from the pet trade to habitat loss and expansion of oil palm plantations, facing these creatures. This second part focuses on what happens to surviving orangutans.
Primatologists: the best hope for apes is the best hope for us
(12/15/2010) Distinguished conservation luminaries, eminent primate experts, ape-suited bucket wielders, a group of African drummers and nearly 1,500 people gathered in London last week for an evening of talks to shine the spotlight on the plight of apes and the forests in which they live, sending a strong message to the climate negotiators hammering out a REDD+ mechanism in Cancun. Hosted by conservation heavyweight Sir David Attenborough, Hope 4 Apes was something of a reunion of the first Hope 4 Apes event that took place ten years ago to raise awareness of -- and funding for -- ape conservation.
The problem-solving ape: what makes orangutans special and why they are threatened
(12/13/2010) Michelle Desilets, Executive Director of the Orangutan Land Trust, spoke with Laurel Neme on her “The WildLife” radio show and podcast about orangutans. In the first part of her interview, they discussed orangutan biology, habits and the interconnected threats, from the pet trade to habitat loss and expansion of oil palm plantations, facing these creatures. The second part covers the process of rehabilitating orangutans and teaching them to be wild.
Mountain gorilla population up by 100 individuals
(12/07/2010) Conservation appears to be working for the Critically Endangered mountain gorilla (Gorilla beringei beringei) in the Virunga massif region, as a new census shows an additional 100 individuals from the last census in 2003, an increase of over a quarter. The Virunga massif is a region in three nations—Rwanda, the Democratic Republic of Congo, and Uganda—and covering three protected area.
Logging concession could extinguish endangered Sumatran elephant population
(11/30/2010) Local conservationists are urging the Indonesian government to halt the destruction of a 42,000 hectare forest in the renowned Bukit Tigapuluh Forest Landscape for a pulpwood plantation. According to researchers, the forest concession—owned by PT Lestari Asri Jaya, a subsidiary of Barito Pacific Group—contains the last population of Sumatran elephants (Elephas maximus sumatranus) in the Bukit Tigapuluh and approximately 5% of the island's total population. In a letter being sent to the Ministry of Forests, conservationists write that the destruction of the forest "would immediately lead to local extinction of elephants in Bukit Tigapuluh". They argue that given its ecological importance, the PT Lestari Asri Jaya forest concession should be placed under permanent protection.
Reforestation effort launched in Borneo with nearly-extinct rhinos in mind
(11/18/2010) The Rhino and Forest Fund (RFF) has partnered with the Forestry Department of Sabah in northern Borneo to launch a long-term reforestation project to aid Malaysia's threatened species with particular emphasis on the Bornean rhino (Dicerorhinus sumatrensis harrissoni), one of the world's most imperiled big mammals. The reforestation project will be occurring in and adjacent to Tabin Wildlife Reserve, which is surrounded on all sides by oil palm plantations.
African apes threatened by rising temperatures
(11/10/2010) Most people wish each day had more than 24 hours. But as the planet heats up, that limited number of hours might push endangered African apes even closer to extinction by making their current habitats unsuitable for their lifestyle, according to a controversial study published on 23 July in the Journal of Biogeography.
Photos: surprises discovered in tiny forest fragment surrounded by palm oil
(11/10/2010) Researchers have uncovered an astounding number of species in a tiny protected forest fragment surrounded on all side by palm oil plantations in the Indonesian island of Sumatra. Researchers with the Zoological Society of London (ZSL), Queen Mary, University of London and the Durrell Institute of Conservation and Ecology (DICE – University of Kent) recorded sun bear (Helarctos malayanus), Malayan tapir (Tapirus indicus), the banded langur (Presbytis femoralis), and agile gibbons (Hylobates agilis), but most notable, was the first record ever of the Ridley's leaf-nosed bat (Hipposideros ridleyi) in Sumatra. The discoveries highlight the importance of preserving even small forest fragments surrounded by agriculture.
Saving the best for last: a journey into the final phases of orangutan rehabilitation
(11/08/2010) Rehabilitation is a powerful word these days. Fashionable, too. In wildlife conservation, rehabilitation can serve functions ranging from augmenting threatened animal populations to desperate attempts to save species from permanent extinction. At its base, rehabilitation consists of handling, preparing and releasing wild animals that have been in some way negatively affected by humans. Rehabilitation programs cover the globe (from cottage-scale sparrow and raccoon rescues in suburban parks to well-established raptor protection programs, wolf rehabilitation and public education about these wild predators in Colorado, semi-touristy rehabilitation centers in Thailand housing everything from gibbons to elephants, vet hospitals dedicated to flu-ridden bobtail lizards in Australia, and sexy lion and cheetah hubs in southern Africa which breed endangered serval cats). The motivations behind these programs are also diverse, but the umbrella goal is unified: to aid the continued survival, so often precarious, of animals valued by people.
Environmentalists must recognize 'biases and delusions' to succeed
(10/18/2010) As nations from around the world meet at the Convention on Biological Diversity in Nagoya, Japan to discuss ways to stem the loss of biodiversity worldwide, two prominent researchers argue that conservationists need to consider paradigm shifts if biodiversity is to be preserved, especially in developing countries. Writing in the journal Biotropica, Douglas Sheil and Erik Meijaard argue that some of conservationists' most deeply held beliefs are actually hurting the cause.
Financial crisis pummels wildlife and people in the Congo rainforest
(09/27/2010) Spreading over three central African nations—Cameroon, Central African Republic, and Republic of Congo—the Sangha tri-national landscape is home to a variety of actors: over 150,000 Bantu people and nearly 20,000 pygmies; endangered species including forest elephants and gorillas; and, not least, the Congo rainforest ecosystem itself, which here remains largely intact. Given its interplay of species-richness, primary rainforest, and people—many of whom are among the poorest in the world—the landscape became internationally important in 2002 when under the Congo Basin Forest Partnership (CBFP) conservation groups and development agencies agreed to work together to preserve the ecosystems while providing development in the region.
Into the Congo: saving bonobos means aiding left-behind communities, an interview with Gay Reinartz
(09/23/2010) Unlike every other of the world's great apes—the gorilla, chimpanzee, and orangutan—saving the bonobo means focusing conservation efforts on a single nation, the Democratic Republic of the Congo. While such a fact would seem to simplify conservation, according to the director of the Bonobo and Congo Biodiversity Initiative (BCBI), Gay Reinartz, it in fact complicates it: after decades of one of world's brutal civil wars, the DRC remains among the world's most left-behind nations. Widespread poverty, violence, politically instability, corruption, and lack of basic infrastructure have left the Congolese people in desperate straits.
Orangutans can survive in timber plantations, selectively logged forests
(09/23/2010) Selectively logged forests and timber plantations can serve as habitat for orangutans, suggesting that populations of the endangered ape may be more resilient than previously believed, reports research published in the journal PlosONE. The study, conducted by a team of researchers led by Erik Meijaard of Jakarta-based People and Nature Consulting International, found roughly equivalent population densities between natural forest areas and two pulp and paper plantation concessions in East Kalimantan, Indonesian Borneo.
New ape species uncovered in Asia
(09/21/2010) Discovering a species unknown to science is a highlight of any biologist's career, but imagine discovering a new ape? Researchers with the German Primate Center (DPZ) announced today the discovery of a new species of ape in the gibbon family, dubbed the northern buffed-cheeked gibbon (Nomascus annamensis), according to the AFP. The new species was discovered in rainforests between the borders of Vietnam, Laos, and Cambodia: an area that contains a number of gibbon species.
Scientists warn little known gibbons face immediate extinction
(09/19/2010) It's not easy to be a gibbon: although one of the most acrobatic, fast, and marvelously loud of the world's primates, the gibbon remains largely unknown to the global public and far less studied than the world's more 'popular' apes. This lack of public awareness, scientific knowledge, and, thereby, conservation funding combined with threats from habitat loss to hunting to the pet trade have pushed seven gibbon species, known as 'crested', to the edge of extinction according to scientists attending the 23rd Congress of the International Primatological Society.
