Scientists, on two separate occasions, have observed orcas ramming into heavy sunfish with such force that the boney fish literally explodes. But why? Scientists, at least currently, have no idea. They could be doing it to portion of food to feed the pod. Or they might just be doing it because they’re bored. Scientists plan to observe more such events to study and understand this behavior better. Watch this video to learn more.This article was originally published on Mongabay

What do snakes, poisonous frogs, and wind turbines have in common? Scientists tested whether warning color patterns inspired by nature could help birds avoid deadly collisions with wind turbines. In video-game-style experiments, great tits, distinctive small birds, were shown different blade designs, including a new pattern based on the bold visual colors used by some animals to deter predators. The birds hesitated longer and approached less often when warning patterns were present — especially the bio-inspired design. Scientists hope that copying nature’s own safety signs could help make wind energy safer for birds.This article was originally published on Mongabay

When researchers mapped almost 100,000 square kilometers of South Africa, or nearly 40,000 square miles, they only found 83 mature adults. They called their project the Free-Roaming Cheetah Census, and it’s the most comprehensive survey of cheetahs ever conducted in the region. The cheetahs that inhabit the unprotected areas here move naturally across borders, going between South Africa, Botswana, Namibia, and Zimbabwe. But farming, construction, development, and fences are making it harder for them to move around. Cheetahs need vast connected landscapes to survive. If they don’t mix with other cheetah groups, their genetic pool can be lost. There’s another big challenge for these animals: farmers. They sometimes kill cheetahs, because they believe cheetahs kill their livestock. But the researchers found that cheetahs hunt mostly wild prey. The species is currently listed as vulnerable, but the census suggests they should be reclassified as endangered in South Africa.This article was originally published on Mongabay

PATAGONIA NATIONAL PARK — Chile. Mongabay traveled to Chile’s Patagonia National Park to follow a women-led team on a mission to bring 13 Darwin’s rheas back to the wild in April 2026. Working with Rewilding Chile Foundation, these dedicated rangers care for the birds around the clock, facing harsh weather, predators like pumas, illegal livestock grazing, and other threats to the park’s fragile ecosystem. For more than a century, the Chacabuco Valley, where the park is located, was dominated by sheep and cattle ranching. Fences fragmented the vast Patagonian steppes and rheas (Rhea pennata) nearly disappeared. But one of South America’s most ambitious rewilding efforts is helping to turn the tide. Tompkins Conservation, the organization behind Rewilding Chile, acquired former ranchlands and began removing thousands of kilometers of fencing, allowing native wildlife to reclaim the landscape. Now, the team is preparing for another milestone: Releasing 13 Darwin’s rheas into the wild. Mongabay followed the rangers in the days leading up to the release, documenting their preparations, the challenges they faced, and their determination to give these birds the best possible chance of survival. Will they succeed? Watch the video to find out. Mongabay’s Video Team wants to cover questions and topics that matter to you.

In a remote community in Malaysian Borneo, fishermen are facing an existential threat: their water source is being polluted. The fish they depend on is dying. Long Jawe village sits on the banks of the vast Bakun Reservoir. It is so remote that most residents only make the five-hour journey to the nearest town once a year, and visitors are rare. When the reservoir was created in the 1990s, the surrounding landscape was flooded. The community has since adapted to this enormous body of water, which is now crucial to their way of life, providing transport, food and livelihoods. But what happens when that water source becomes polluted? Join Conservation Entangled host Izzy Sasada as she travels to Long Jawe to investigate what could be behind the pollution.This article was originally published on Mongabay

Every year, thousands of salamanders and frogs try to cross from their wooded winter homes in the U.S. state of New Hampshire to the swamps they breed in. But the road is a dangerous place — unless you have the help of New Hampshire’s Salamander Brigades.This article was originally published on Mongabay

Vast tracts of Thai farmland have been poisoned by chemicals linked to mining in Myanmar, With toxins carried into Thailand by at least six transboundary rivers. A Mongabay investigation has found more than 50 companies in Thailand importing minerals from Myanmar’s polluting mines. Antimony, copper, lead, manganese, tin, tungsten and other critical minerals worth millions of dollars are imported from Myanmar to Thailand And mostly sold on to China. Few Thai companies know where in Myanmar the minerals come from, If the mines are legal, whether they’ve contributed to river pollution or if the minerals imported are even what’s listed on paper. Thai, Burmese and Chinese companies are all profiting from mines that have contaminated rivers, leaving downstream communities with no clean water, food security or livelihoods as a public health crisis unfolds.

12 critically endangered Nubian Giraffes were recently relocated from their home at Murchison Falls National Park to a reserve over 100km away. One of the reasons? Murchison Falls is now being opened up for oil extraction, as almost half of Uganda’s oil reserves are thought to lie there. National parks are home to some of the world’s most important biodiversity, and they are increasingly recognised as vital tools in tackling both biodiversity loss and climate change. But around the world, these protected areas are increasingly being undermined by political and economic priorities. So how protected are they, really?

A giant octopus devouring a jellyfish. An ultra-fast gossamer worm. These are just a couple of the 31 new species scientists discovered on a recent expedition off the coast of Brazil. They explored the ocean’s midwater zone — the vast space between the sunlit surface and the seafloor — which is the Earth’s largest and least explored habitable ecosystem. While it can take researchers decades to identify and describe new species, state-of-the-art technology like 3D lasers and advanced microscopes helped the team confirm these new species within a matter of days.This article was originally published on Mongabay

Fireflies are disappearing from the Indonesian island of Bali… but local Wayan Wardika is trying to bring them back. Fireflies in Southeast Asia are vanishing due to habitat loss, light pollution, pesticide use, and climate change—and the same is happening on this rapidly developing island. In 2020, he launched Bring Back the Light, Indonesia’s only firefly conservation initiative. He and his small team of scientists focuses on breeding fireflies to return to the wild. But through this work, Wayan has also gathered the importance of habitat protection – only by doing so will firefly numbers be able to grow sustainably. He is now focused on encouraging neighboring farmers to ditch the chemicals and go organic, in order to boost firefly numbers. Watch the full video.This article was originally published on Mongabay

BALI — Indonesia. Wayan Wardika used to see “clouds of fireflies” as a child growing up among the rice fields of Bali, Indonesia. But 40 years later, he realized that the fireflies in his village had all but disappeared. Fireflies in Southeast Asia are vanishing due to habitat loss, light pollution, pesticide use, and climate change—and the same is happening in rapidly developing Bali. Which is a loss for us all, as fireflies are both ecologically and culturally significant. In 2020, Wayan decided to bring the fireflies back, by launching Indonesia’s only firefly conservation initiative called Bring Back the Light. He and his small team of scientists focuses on breeding fireflies to return to the wild. But through this work, Wayan has also gathered the importance of habitat protection – only by doing so will firefly numbers be able to grow sustainably. He is now focused on encouraging neighboring farmers to ditch the chemicals and go organic, in order to boost firefly numbers.
