In November 2017, an ecologist was in the middle of a research expedition in central Amazonia when he spotted something strange: a black-chinned antbird resting on a branch with an erebid moth on the back of its neck. The moth was probing one of the bird's eyes with its proboscis and appeared to be drinking from it. About 45 minutes later, they came across a different moth drinking from the eye of another resting antbird. Butterflies and bees also drink the eye secretions of other animals—butterflies are partial to basking crocodiles, whereas bees like turtle tears. But fast-moving birds are unlikely hosts for these insects. Learn more: #ScienceMagArchives

Most salamanders live in streams and under rocks or logs, but the wandering salamander has a high-flying lifestyle. These 13-centimeter-long amphibians spend much or all of their lives in coastal redwoods, some of the tallest trees in the world. In 2022, a laboratory study showed how they can descend by jumping, slowing their fall by spreading their limbs like a skydiver. Learn more during #AmphibianWeek:

Hammer a nail into a tree, and it will get stuck. So why doesn't the same thing happen to the sharp beaks of woodpeckers? Scientists may finally have the answer. In a 2021 study, researchers took high-speed videos of two black woodpeckers pecking away at hardwood trunks in zoos and analyzed them frame by frame to see how the head and beak moved throughout each peck. The bird's secret: an ability to move its upper and lower beaks independently, the team reports. Learn more: #ScienceMagArchives

In November 2024, environmental police in Rochedo, Brazil, stumbled on an unexpected sight: thousands of orange-and-black bumblebee catfish scaling the slippery rocks behind waterfalls on the Aquidauana River. A week later, a team of Brazilian scientists arrived to document the unprecedented event, detailing their findings. These videos provide rare insight into the lives and migrations of these little-studied catfish, the authors said. This genus of small South American fish, which inhabits the rocky bottoms of fast-flowing streams, only became known to science in 2017. Learn more:

About a decade ago, a baker in a small mountainous village in southern Austria noticed his cow doing something unusual. When Veronika had an itch, she would grab a stick in her mouth and use it to scratch her body. Over the years, the brown bovid’s technique improved. She could pick up objects as large as a broom or rake and move them around with her prehensile tongue, changing their length and orientation to ensure the best possible scratch. The behavior isn’t just a clever trick: It’s the first documented case of tool use in cattle, scientists report. And, it turns out, one of Veronika’s skills has only been seen in humans and chimpanzees. Learn more:

Dragonflies perform an amazing stunt so quickly most people never see it. After emerging from a pond dive, the insects execute several summersaults in midair—a feat scientists have captured for the first time with high-speed video. The bugs aren’t showing off: The quick dip cools them down, and the loop-the-loops help them dry off by flicking away the water. Learn more:

In July 2023, researchers on a whale watching expedition in the Caribbean Sea encountered an unusual scene: 11 sperm whales clustered tightly at the water’s surface. The animals began to inch closer and closer together in the waters off the island of Dominica, with their attention turned to one individual, until a burst of blood tinted the water. At first, the scientists—part of Project CETI, a nonprofit that studies how sperm whales interact—thought the animal had been attacked. But then they saw a tiny tail pop out of the water. The researchers quickly realized they had in fact observed a group of whales helping a calf take its first breath. Even more fortuitous, they had captured it on video from a drone. Read more:

In a Southern California aquarium, a young leopard shark rushes headfirst toward a plastic squid toy and then—as if in a game of chicken—makes a last-minute dash to the left, barely clearing the dangling rubber tentacles. Meanwhile, his tankmate, a California skate, grabs an orange ring with her mouth, rolling the textured plastic around with her tongue. And over at the tank’s sandy bottom, a hovering horn shark glides over to a bright yellow hoop and squeezes himself—along with all his jutting fins—right through it. These cartilaginous fish aren’t putting on a show. It seems they’re playing—just for the fun of it, according to the team behind the new study. The findings, the researchers say, offer the strongest evidence yet that sharks engage in play behavior. Learn more:
