Sixteen Elephants dead in series of poisoning incidents in Amboseli National Park, Kenya.

Sixteen Elephants have been found dead with apparent cyanide poisoning in the Amboseli National Park in Kenya since 24 June 2026. This has raised concerns about a potential new wave of Human-wildlife conflict in the park, where Elephants were once almost wiped out by poaching, but which is now home to a population of 36 000. All of the Elephants died outside of the Amboseli National Park itself, but within the greater Amoseli ecosystem, in the area around Kimana Sanctuary and Kuku Ranch, community-run wildlife projects linking Amboseli National Park to the Tsavo National Park to the east.

Initially, park authorities were concerned that the Elephants may have been poisoned by a cyanide-based insecticide sprayed on crops on one of the farms surrounding the park, as several of the dead Elephants had stomachs filled with tomatoes. Elephant raids on croplands close to Amboseli are a known problem, and while cyanide-based insecticides are illegal in Kenya (which maintains strict rules on the use of agricultural chemicals in order to gain access to lucrative European markets), they are legal in neighbouring Tanzania, with occasional incidents of smuggling and illegal use in Kenya being reported.

However, local farmer's representatives have strongly denied this, claiming that despite the problems of crop raiding, most farmers love the region's Elephants and would not voluntarily harm them. Furthermore, they note that that it would take a considerable amount of cyanide to kill an Elephant, and farms are also impacted by crop raiding by other large Mammals, none of which seem to have been affected.

Another possibility is that the cyanide could have been used in an illegal gold mining operation either within, or close to the Amboseli National Park (while gold is not generally soluble, it can be dissolved in solutions of sodium cyanide, a method which can be used to leach gold from ore rock), although the Kenya Wildlife Service are confident that no such activities are taking place. This makes deliberate poisoning of the Elephants the most probable cause, and while the reason for this is unknown, the most likely explanation would be that it relates to the extensive farmland now surrounding Amboseli and the other parks of the region, which supply vegetables to cities such as Nairobi as well as overseas markets. While many Animals occasionally raid such farms, Elephants are uniquely destructive, with individual Elephants able to consume over a tonne of vegetables within a short period of time.

Manis pentadactyla: The Chinese Pangolin confirmed to be living in Pakyong District, Sikkim.

Pangolins are solitary, nocturnal, and generally cryptic Mammals, found across Africa and Asia. They feed on Ants and Termites, and have a covering of scales, made from fused hairs, which are their main defence against predators, rolling into a ball with these forming the outer covering. There are eight recognised species of Pangolin, four in Africa and four in Asia, two of which are listed as Vulnerable under the terms of the International Union for the Conservation of Nature's Red List of Threatened Species, three as Endangered, and three as Critically Endangered. One of these Critically Endangered species is the Chinese Pangolin, Manis pentadactyla, which is found across parts of Nepal, Bhutan, northern India, Bangladesh, Myanmar, China, and Taiwan. In India it is known to be present in Arunachal Pradesh, Meghalaya, Nagaland, Manipur, Tripura, Mizoram, and Assam, with occasional reports of its presence in Sikkim and West Bengal, although none of these have been confirmed.

In a paper published in the Journal of Threatened Taxa on 26 June 2026, Prashanti Pradhan of the Sikkim Alpine University, and the Assam Downtown University, Jampal Dorjee Bhutia, also of the Sikkim Alpine University, and Prem Kumar Chhetri and Bharat Kumar Pradhan of the Forest & Environment Department of the Government of Sikkim, document the first confirmed sighting of the Chinese Pangolin in Pakyong District, Sikkim, and provide photographic evidence to support this.

Pradhan et al.'s report is based upon a Pangolin which was found in Barapathing Village in Pakyong District on 31 March 2024. Barapathing Village is located at an altitude of between 1150 and 1700 m in an area where subtropical to temperate broad-leaved forests are being encroached upon by agricultural land and Human settlements, with anthropogenic pressures increasing due to the construction of the 717B National Highway, and associated infrastructure. 

The Pangolin was found by a local villager wandering within their backyard, and apparently lost and looking for food. The villager, who was unfamiliar with the species, attempted to drive the Pangolin away, though it was unperturbed by this, and apparently tolerant of Humans, potentially indicating that it had been living in a Human-dominated environment for some time. The Pangolin was eventually allowed to settle in a room, while the resident called the Barapathing Territorial Range Forest & Environment Department, who collected the Animal and relocated it to a subtropical forest downstream of the village.

The rescued Animal was identified as a Chinese Pangolin, Manis pentodactyla, on the basis of its distinct morphological characteristics, such as overlapping keratinous scales, an elongated snout, and robust body form. The photographic evidence collected by Pradhan et al. constitutes evidence that this species is present in the Pakyong District of Sikkim. Local people were able to identify the Animal as a Pangolin using the Nepali word 'Saalak', but reported that they had never seen one so close to a Human habitation before.

The photographs and a description of the Animal were later sent to Vikram Aditya, the principal scientist at the Centre for Wildlife Studies in Bengaluru, Karnataka State, and a member of the International Union for the Conservation of Nature's Pangolin Specialist Group, who confirmed the diagnosis of this being a Chinese Pangolin.

Pangolins are threatened by habitat loss and fragmentation, driven by deforestation, forest fires, and road development, across their range. Sikkim has had one of the greatest expansions of its road network of any state in India during the last decade, with a major road upgrading project close to the village of Barapathing, which is likely to have contributed to both habitat destruction and a greater rate of Human encounters for Pangolins in the area. 

Animals can sometimes survive in altered landscapes by adapting their behaviour, however, this can lead them vulnerable to additional hazards, such as increased hunting. The hunting and trafficking of Pangolins is known to be a hazard for Pangolins in Sikkim, in 2021 a group of five people was arrested trying to smuggle a dead Pangolin from Sikkim into Bhutan, and when questioned they confessed the Animal had been killed in a wildlife sactuary in Sikkim. They also hinted at there being an international wildlife trafficking network operating across the eastern Himalayan region. 

Pradhan et al. suggest that there is an urgent need for a baseline ecological study on Chinese Pangolins in Sikkim, in order to better understand the threats linked to development-related habitat fragmentation, illegal hunting and transboundary trafficking, and to enable the development of a conservation plan for the species in the state,

Bison which killed woman in South Dakota to be relocated.

A Bison which killed a 70-year-old Canadian woman in Custer State Park, South Dakota, is to be relocated to another area. The incident happened on 18 May, when the woman and her husband encountered a group of five Bison bulls on the Grace Coolidge Trail, which runs through the park. At this time the bulls were about 500 m ahead of the couple, who allowed them to move off before following. A little while later the couple encountered the Bison again, though this time they were only about 15 m away. The couple waited for them to move before starting to follow, but this time moved while the Animals were still in site, causing one of the bulls to turn and charge.

The initial charge resulted in the woman being thrown about two metres in the air, sustaining serious injuries to the leg and abdomen. The Bison then stood over the injured woman for about 15 minutes while her husband hid behind a tree and called the local sheriff's office. During this time the woman remained conscious, and was able to talk to her husband. The bull eventually wandered off, after which the husband approached the woman, but this caused the Animal to turn and charge again, this time throwing her about three meters into the air and causing fatal injuries. After this the Bison walked off, and the husband attempted to perform CPR, being joined shortly after by first aid-trained park staff, but it was impossible to save her. The death was the first Bison-related fatality in the park for 21 years.

Following the incident, rumours began to circulate that the park authorities planned to euthanize the Bison, leading to a public outcry, and many people contacting the South Dakota Governor’s Office, the South Dakota Game, Fish, and Parks and Custer State Park, asking for the Animal to be spared. On Wednesday 10 June the Rosebud Sioux Tribe Game, Fish and Parks announced that they were willing to rehome the bull and take care of its welfare. 

Bison are large animals, the American Bison can reach 1.8 m in length and weigh around 900 kg, and have notoriously unpredictable tempers, often appearing placid and indifferent to their surroundings, and then charging without warning. They can reach speeds of 35 km per hour, and both sexes have horns, which can make unexpected charging highly dangerous.

North America is thought to have been home to about 50 million Bison at the beginning of the nineteenth century, a number that fell to less than a thousand individuals by the middle of the twentieth century due to over-hunting, not just for the purpose of food, but as part of a conscious effort to change the landscape from one amenable to traditional, Native American, lifestyles to a landscape suitable to European-style farming. However since the mid-twentieth century conservation efforts and breeding programs have reversed this decline, with the population now about 530 000 across the continent, including around 40 000 in South Dakota.

Woman killed by Elephant in Kerala State, India.

A woman has died after being trampled by an Elephant on Monday 8 June 2026 in the village of Sinkukandam near the town of Suryanelli in the Idukki District of Kerala State, India. The woman, identified as Mari, a 36-year-old widow, mother of two, and day-labourer, encountered a mother Elephant with a calf while escorting her 11-year-old son to catch a school bus, at about 8.30 am local time. Both were attacked by the Animal, and subsequently rushed to a local hospital by a passing auto-rickshaw driver. Here Mari was pronounced dead, while her son, Dakshan, was transferred to the Kottayam Government Medical College Hospital for further treatment.

The village is close to the Chinnakanal Reserve, which is home to a population of 18 Elephants. About 50 people are thought to have been killed by Elephants in and around Chinnakanal since 1990, ten of them by a single male known as 'Arikomban' who was eventually relocated away from the area by the Kerala Forest Department in 2023. This has placed considerable strain on the local Human population, and their ability to live alongside the area's Elephants.  

The major problem appears to be that the Chinnakanal Reserve covers an area of about 4 km², although only about half of this is utilised by the Elephants, who instead spill out into nearby farms and villages, often stealing food from Humans and coming into conflict with them. In an attempt to manage this conflict the Forest Department has set up a system alerts on social media and messaging platforms, which message people warning them that Elephants are in their area. However, local people have complained that they are not simply able to simply stop going about their daily business whenever Elephants wander into the area. On the day of the latest incident an alert had been put out, but visibility was very low due to rains and fog, apparently causing the victims to come close to the Elephants without realising the danger they were in until too late.

In 2022 Raju Francis of the Kerala Forest Development Corporation produced a report recommending the construction of a series of solar-powered electric fences to protect farmland and residential areas from Elephants emerging from the forest. Despite agreeing to this proposal, four years on the Forest Department has yet to install a single stretch of fencing, and is unable to confirm when this will begin, something which local people have described as grossly negligent, leaving their property and families vulnerable to Elephant attacks.

Asian Elephants, Elephas maximus, are classified as Endangered under the terms of the International Union for the Conservation of Nature's Red List of Threatened Species, as the population has declined by more than 50% over the last three generations (about 75 years for Elephants). There are currently about 50 000 Asian Elephants (although Elephants are notoriously difficult to count, despite being such large Animals) scattered across Bangladesh, Bhutan, Cambodia, China, India, Indonesia, Laos Malaysia, Myanmar, Nepal, Sri Lanka, Thailand, and Vietnam. However, this population is now highly fragmented, with most Elephants living in small groups, reproductively isolated from other groups, and often coming into conflict with local Human populations as the land allocated to Elephants shrinks.

Observing Animal and Human interactions around a Marburg Virus-infected Bat colony.

Zoonotic infections, diseases which spread from an Animal host into a Human population, are a serious threat to public health, in some cases being the source of pandemics which kill millions of people around the globe, such as the Influenza and Covid Viruses and the medieval Plague outbreaks. Filoviruses, such as the Bundibugyo, Ebola, Marburg, and Sudan Viruses, can cause outbreaks of hemorrhagic fever which kill hundreds or even thousands of people in tropical Africa, after jumping from a natural host, usually a Fruit Bat. The Bats themselves seem to suffer little harm from infection with these Viruses, but Humans and other Animals often succumb very rapidly. 

Since the nature of the wild host of these Viruses became apparent, public health campaigns in many countries have tried to minimise the extent to which people interact with Fruit Bats, but the often remote nature of the communities most at risk, combined with the ability of the Virus to jump from Bats into a variety of other hosts before infecting Humans, has limited the effectiveness of these, underlining the need to better understand the nature of interactions between Fruit Bats, Humans, and other Animals.

In a letter published in the journal Current Biology on 20 April 2026, Bosco AtukwatseOrin CornilleJohnson MuherezaWinfred Nsabimana, and Yahaya Ssemakula of the Kyambura Lion Project of the Volcanoes Safaris Partnership Trust, Eric Enyel of the Uganda Wildlife Authority, Charlie Gould of the School of Biological Science at the University of EdinburghArjun Gopalaswamy of Carnassials Global, and Alexander Braczkowski, also of the Kyambura Lion Project of the Volcanoes Safaris Partnership Trust, present the results of an study in which camera traps were deployed at Python Cave in the Queen Elizabeth National Park, the dwelling place of a colony of  Egyptian Rousette Bats, Rousettus aegyptiacus, known to act as a reserve for Marburg Virus.

The camera traps were deployed as part of a carnivore-monitoring program in Queen Elizabeth National Park between 16 February and 23 June 2025, with a total of 8832 hours of filming producing evidence of at least 14 species of Animal visiting the size, including Carnivores, Primates, Raptors, and Reptiles. The most common visitors to the cave were Nile monitors, Varanus niloticus, (72 visits), Large Spotted Genets, Genetta tigrina, (69 visits), and Palm-nut Vultures, Gypohierax angolensis, (35 visits). The cave was visited twice by Olive Baboons, Papio anubis, and ten times by Blue Monkeys, Cercopithecus mitis, which were seen actively preying on Bats. African Fish Eagles, Icthyophaga vocifer, made 33 visits to the cave, Black Sparrowhawks, Astur melanoleucus, made 19 visits, Crowned Eagles, Stephanoaetus coronatus, made 17 visits, and Verreaux’s Eagle-owls, Bubo lacteus, made six visits. Seventeen Leopard visits were directly recorded, but parts of a cycle in which the same Leopard repeatedly entered the cave, captured Bats, and exited with them were recorded, leading the team to conclude at least 43 such hunts took place during the study time. A total of 63 incidents of hunting or scavenging Bats by different species were recorded, with a further 258 incidents of Animals entering the caves for less clear reasons.

The distribution of detections per species across 368 trap nights at Python Cave recorded using  6 remote, solar-powered camera traps. Blue indicates predation and scavenging events, whereas  orange represents detections where cave exploration, entry, exit, or resting was observed. Atukwatse et al. (2026).

More alarmingly, over the course of the study Atukwatse et al. also observed 214 individual Humans approaching the cave. These came in 22 different groups, including school groups, researchers, and tourists, many of whom came within meters of the cave entrance (a direct contradiction of park regulations), bypassing a designated observation platform 30 m from the entrance. Only one person, a tourist, was observed to wear a mask when approaching the cave.

Atukwatse et al. do not suggest that these observations represent evidence of Virus transmission, but rather a direct record of ecological interactions at a potential spillover site. This included direct predation of potentially-infected Bats during repeated visits to the cave, and provide direct evidence of the predator-guild targeting Bats in this setting.

(ix) A group of Olive Baboons, Papio anubis, at the cave mouth, possibly foraging on Bat guano. Atukwatse et al. (2026).

Unlike other famous tropical Bat roosts within caves, such as Kitaka Mine in Uganda, Kitum Cave in Kenya, Goroumbwa Mine in Democratic Republic of Congo, or Macaregua Cave in Colombia, Python Cave lacks a vertical space separating the Bats from ground-based predators. Parts of the cave roof have collapsed, and the cave is partly filled with large volumes of guano, providing predators a way of directly reaching the Bats where they roost. This it turn provides an easy opportunity for any Virus present in the Bat community to spread to other wildlife within the cave. Atukwatse et al. observed instances of bats falling from the overcrowded roof of the cave, then having to crawl over the floor, presenting another tempting target for both terrestrial and airborne predators.

The presence of piles of Bat bones and frequent and repeated visits to the caves by a variety of predators indicates that the site has become a prime feeding site for both predators and scavenges, and that to some extent the richness of the resource has led to a relaxation of normal inter-species hostilities, with, for example, Fish Eagles feeding alongside Vultures, Nile Monitors feeding alongside Pythons, and even a Genet and Python seen together. This implies a loss of territoriality and aggression only seen at the most abundant food sites, although on one occasion  Atukwatse et al. did observe a Crowned Eagle and a Nile Monitor squabbling over a Bat.

These interactions are all the more remarkable in that they are occurring at a site with a frequent Human presence, something which many Animals avoid where possible. The Uganda Wildlife Authority has placed an observation platform about 30 m from the entrance to Python Cave, with the specific intention of limiting Human exposure to Marburg Virus-infected Bats, but despite this Atukwatse et al.'s camera traps recorded Tourists, students from a nearby wildlife training institute, and even school trips approaching the cave mouth without any form of protection. It is particularly concerning that this was happening during the Bat's birthing season, when they are known to shed the Virus at a higher rate. Atukwatse et al. recognise that Bat-viewing is a valuable contribution to the nation's ecotourism income, but nevertheless recommend that the Uganda Wildlife Authority imposes stricter regulation on the site, with mandates for protective gear, enforced distancing, and locally trained guides to serve as sentinels for biosurveillance and education.

It has generally been assumed that the spillover events which lead to outbreaks of Marburg Virus Disease, and other zoonotic infections, occur in locations effectively beyond the observation of science. Atukwatse et al.'s results refute this, providing an example of a site where Marburg-infected Bats are interacting with a variety of other Animals, which is also integrated into the local tourist industry. Some of the species observed, such as Blue Monkeys, have previously been associated with Marburg Virus, and are commonly hunted and consumed by Humans as bushmeat. The consumption of Bats by these Monkeys presents a new route by which Marburg Virus could make its way from the wild Bat reserve into Human populations. Atukwatse et al. recommend that serological surveys are carried out of both the predators seen frequenting Python Cave, and of park rangers who regularly enter the site, in order to assess potential exposure to Marburg or other Filoviruses. This, combined with enhanced surveillance of Python Cave and other similar sites, could enable the development of a new dataset to complement the genomic tools already being developed.
