In Chile’s Patagonia National Park, Mongabay meets a women-led team preparing to release to the wild 13 Darwin’s rheas, a bird that nearly went extinct in the region just 20 years ago. Mongabay follows the preparations for the reintroduction and witnesses how the women’s efforts are helping to protect the birds and rebuild a self-sustaining population of this flagship Patagonian species.This article was originally published on Mongabay

A newly discovered Australian ballista spider has evolved one of the most specialized hunting strategies ever seen. Instead of chasing prey, it builds a spring-loaded silk snare that appears to target a single species: The aggressive green tree ant. Scientists think the spider may even lure the ants into attacking the trap, causing them to trigger the catapult on themselves. It’s the first known spider whose web is designed for one prey species — and the first where the prey activates the trap.This article was originally published on Mongabay

Camera traps in Spain have captured a behavior never documented before in a wild cat: Iberian lynxes soaking their prey in water before eating it. Over five years, researchers recorded multiple females carrying dead rabbits to water troughs and repeatedly dunking them underwater. Scientists aren’t sure why. The behavior may help lynxes stay hydrated during hot summers, soften prey for cubs, or serve another unknown purpose. The discovery comes from long-term monitoring of the Iberian lynx, a species that has made a remarkable recovery from the brink of extinction and continues to surprise researchers with previously unseen behaviorsThis 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

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.
