In Salonga National Park in the Democratic Republic of Congo, researchers and trackers are working to habituate a group of about 60 bonobos. The aim is to help the great apes accept a limited human presence, first for research, and later for carefully managed tourism. The process is slow. Trackers may leave camp around 3 a.m. to reach the previous night’s nesting site before the bonobos (Pan paniscus) wake. They then follow the group through the forest until the endangered apes build new nests in the evening. “The whole idea of habituation is that you meet the group every day in a very friendly, non-interactive way so they accept you as part of the forest,” Felix Bofeko, an assistant researcher in the program, told Mongabay’s David Akana. Habituation requires the same people, same restraint, and same routine, repeated long enough for the animals to stop treating human presence as a threat. When the work began, the bonobos fled at the sight of people. Now, Bofeko says, researchers can sometimes remain with them for two or three hours. Two visitors may be tolerated. Three or four may still be too many. The work has value even before tourism begins. Habituated animals can be observed more closely. Researchers can collect fecal and urine samples for genetic, pathogen, and diet analysis. Salonga is part of the Bonobo Diversity Project gathering standardized data across the DRC. Camera traps and acoustic monitoring are also being introduced, with the hope that real-time systems could eventually detect gunshots and help guide patrols. Health risks must be managed carefully. Great apes are vulnerable to human-borne diseases, including respiratory infections. Salonga’s staff follow screening and hygiene protocols, wear masks near bonobos, and keep a minimum distance from the animals. The closer conservation gets to wildlife, the more it depends on discipline. The project also shows how much field conservation depends on local relationships. Salonga’s managers have hired locals, including former hunters whose knowledge of the forest makes them strong trackers. More than 10 local people now have jobs linked to the project. Park staff have also installed internet hubs and complaints channels in nearby communities, giving residents a more regular way to communicate with management. That work matters because many people around Salonga have long associated the park with restrictions, enforcement, and arrests for poaching. Bonobo tourism remains a future prospect. The more immediate change is that some residents are being paid for knowledge that once supported hunting and is now being used for protection. For funders and conservation planners, Salonga offers a useful lesson. The visible result may one day be a visitor watching bonobos in the forest. The work behind it is less visible: patient tracking, health protocols, local hiring, basic infrastructure, and enough continuity for both people and animals to adjust.

The white-necked picathartes is easy to miss. In Taï National Park, in southwestern Côte d’Ivoire, it nests beneath rocky overhangs, shaping mud cups against stone walls deep inside the forest. It may appear for only a few seconds, long enough to show its bare yellow head, black cheek patches, and long-legged frame, before it vanishes again into the trees. The bird’s elusiveness reflects the kind of habitat it needs, reports contributor Ryan Truscott for Mongabay. Taï is the largest intact remnant of the Upper Guinean rainforest, a forest type that once stretched across much of West Africa. Its boulders, old animal trails, giant mahoganies, duikers, hornbills, monkeys, and river hogs are part of a system that still retains much of its original complexity. The white-necked picathartes (Picathartes gymnocephalus) depends on rocky nesting sites and surrounding forest cover. Other species help maintain the forest itself. Hornbills, primates, and mammals move seeds through the canopy and across the forest floor, helping trees and lianas regenerate far from their parent plants. That makes Taï important beyond the survival of any single rare species. Protected areas are often judged by their boundaries, patrol numbers, and better-known animals. A fuller measure is whether ecological relationships continue: animals using long-established routes, seed dispersers moving between fruiting trees, birds returning to nesting walls, and rangers knowing enough of the forest to find those places again. Keeping those relationships intact depends on ordinary field capacity. Rangers need training, equipment, safe access, and time in the forest. Local organizations need support to monitor species whose decline may be easy to miss until it is advanced. Conservation groups need to treat field signs, ranger knowledge, and repeated observations as evidence. Asked what the white-necked picathartes means to Ivorians, ranger Gliman Hyacinthe gave Truscott a simple answer: “It’s rare. It’s beautiful.” In Taï, the bird also points to a forest where the conditions for rare species are still present. Read Ryan Truscott’s story here.

In a recent paper, researchers detailed how critically endangered hooded vultures (Necrosyrtes monachus) were absent around most slaughterhouses and landfill sites they visited near N’Djamena, Chad’s capital.
“That doesn't really make sense, because there's a ton of food,” said study co-author Nico Arcilla, president of the International Bird Conservation Partnership. Nearly half the local residents interviewed by the researchers said they knew of recent poisoning incidents in the area, and more than one-third stated they were aware of poachers from countries such as Nigeria, Niger, Benin and Cameroon trapping or killing vultures.
“The driver appears to be coming from West Africa, and it generally seems to point back to Benin or Nigeria,” Arcilla said. Belief-based use practices appear to be largely absent in Chad, she added.
In another study, led by Chaffra, surveys in Benin’s traditional markets found that while most vultures on sale originated from other West African countries, such as Ghana, Burkina Faso, Nigeria and Niger, there were also birds from Cameroon and Gabon. Another 2025 market survey in Benin found a small number of birds sourced from Cameroon. A 2014 paper revealed that vulture parts on sale in Nigeria were sourced from as far as Sudan.
“In several cases, trade appears to cross national borders, highlighting the need for regional cooperation to better understand and combat these networks,” Chaffra said.
Darcy Ogada, program director at The Peregrine Fund who wasn’t involved in the research, said it isn’t surprising the supply chain is very far-reaching since vultures in West Africa have become scarce.
“That should raise the alarm,” Ogada added. “It's going to keep moving to where populations are relatively much better.”
Arcilla said that awareness-raising in communities, law enforcement, and conservation efforts are urgently needed, targeting both natural and urban areas where vultures persist.
“It is also necessary to continue research into supply chains and to promote sustainable alternatives in order to reduce demand for vultures and their parts,” Chaffra said.
