Wildlife

Human development—such as roads—affects wildlife. But so does the presence of people.

The Mere Presence of Humans—Not Just Our Changes to the Land—Can Alter Wild Animals’ Behaviors, a New Study Suggests

Researchers examined GPS tracking data from thousands of animals representing 37 species and anonymized cellphone location data from 2020, a year of Covid-19 lockdowns, and the previous year

The researchers studied four captive belugas housed at the New York Aquarium of the Wildlife Conservation Society.

Belugas Can Recognize Themselves in Mirrors, Joining a Short List of Nonhuman Species That Show Signs of Self-Awareness

The researchers hope that this new understanding of cognition in the toothed whales will increase human empathy and concern for the animals, leading to more efforts to protect them

Researchers found evidence of degenerative joint disease, trauma and other health problems.

Whalers Didn’t Just Sing Sea Shanties and Seek Adventure. Proof of Laborers’ Grueling Work Is in Their Skeletons, Buried in the Arctic

Remains buried on Svalbard show the brutal toll whaling took on men in the 17th and 18th centuries. Climate change threatens these kinds of archaeological sites across the Arctic

Mediterranean monk seals are among the rarest pinnipeds in the world.

Mediterranean Monk Seals Hide in Underwater ‘Bubble Caves’ to Avoid Tourists During the Busy Summer Season, a Study Suggests

Researchers caught the rare pinnipeds resting and sleeping in a secluded chamber on the Greek islet of Formicula. The findings suggest that these small caves should be included in efforts to protect the animals’ habitat

Gentoo penguins have been considered a rare beneficiary of climate change due to their population growth on the Antarctic Peninsula. Splitting the birds into four species brings to light regional threats and declines.

Gentoo Penguins Are Actually Four Different Species, Scientists Say, Revealing They’re Not Quite ‘Winners’ of Climate Change After All

A new study indicates that the adaptable birds evolved into distinct lineages as isolated populations shifted to match their environmental conditions over time. The work has implications for how conservationists assess threats to gentoos

Tuerkayana hirtipes, a true crab species examined in the study

When Did Crabs Evolve Their Iconic Sideways Scuttle? Scientists Traced It to a Common Ancestor That Lived 200 Million Years Ago

The findings suggest that their famous lateral movement evolved just once. It may have helped the animals rapidly spread and diversify because moving in two directions meant they could easily escape predators

The skeleton first emerged from an eroded road cut in 2000 or 2001.

Likely Kicked by a Kangaroo, This Dingo Healed a Millennium Ago Thanks to Help From an Aboriginal Community That Continued to Honor It for 500 Years

New research shows that the ancestors of the Barkindji people in Australia ritually added river mussel shells to a burial site for centuries after the dingo died, suggesting they cared for it deeply

A chick hatches around 18 days after embryo transfer to the artificial egg, according to the company.

‘De-Extinction’ Company Says It Hatched Chicks From Artificial Eggs, Paving the Way for Resurrecting Dodos and Other Bygone Birds

Colossal Biosciences announced that 26 live baby chickens have emerged from 3D-printed honeycomb structures. But the company does not plan to detail the system in a paper, and its mission has faced criticism

Each by-the-wind sailor is made of a community of genetically identical organisms called "zooids" that perform different tasks.

Millions of Bright Blue Blobs Called ‘By-the-Wind Sailors’ Are Littering Beaches Along the West Coast

The strange creatures are washing up on shores across California, Oregon and Washington this spring—and making the coast smell especially fishy

Artist's reconstruction of newly described koala species. 

A Dimpled Koala Fossil Found in a Cave in Western Australia Revealed Why This Previously Unknown Species Went Extinct

The new study found that they lost their arboreal habitat due to a drying climate, a dire warning for the modern-day marsupials that face a similar threat

In laboratory experiments, house crickets groomed an antenna that had been touched by a hot soldering iron.

Can Insects Feel Pain? New Research Suggests That Crickets Do

Used for food, feed and research, the critters are among the most widely farmed bugs. The study authors say humans should work to reduce harm in insect farming, handling and experimentation

To estimate the wolf population, researchers observed animals from planes, followed tracks on the ground and inspected kill sites this year.

Wolves Are Thriving at Michigan’s Isle Royale National Park, Reaching Their Highest Numbers in Almost 50 Years, New Data Suggests

Scientists estimate that 37 of the animals now roam the rugged archipelago, which has contributed to the dwindling moose population. But the predator-prey ratio might be stabilizing

Two Alpine ibexes butt heads, slamming their horns together in a powerful battle that can be heard from far away. They wandered up the slope together afterward.

See 15 Stunning Images That Won the German Society for Nature Photography’s Annual Contest

From a lunging frog to the majestic movements of penguins, the honored photographs capture the wonder of wildlife and beauty of natural landscapes

Researchers studied social learning in the birds by introducing a novel food item: colorfully dyed almonds.

Wild Cockatoos Learn Which Snacks Are Safe to Eat by Copying Their Friends, New Research Suggests

Munching on the wrong items can lead to illness, but social learning might help the birds avoid making a potentially deadly mistake. The phenomenon could help explain why certain cockatoos have fared so well in urban environments

About 50 organisms have been named for David Attenborough or elements of his legacy, from an orchid to a marine worm to one of the earliest known predators.

David Attenborough Has Inspired Countless Scientists. To Mark His 100th Birthday, Here Are Ten Living Things They’ve Named After Him

Researchers around the planet grew up watching documentaries hosted by the English broadcaster and naturalist, which sparked their love of the natural world. Now, their discoveries become tributes to his legacy

Chonkers, a Steller sea lion, is much larger than his companions, California sea lions.

Chonkers the Massive Sea Lion Drew Crowds to San Francisco’s Famed Pier 39. Then, a New Chunky Showstopper Stole His Identity

The Steller sea lion was an unusual visitor to the pier, which typically hosts smaller California sea lions. However, he may have moved on days ago, during which time a humongous member of the area’s more common species tricked onlookers

A bison herd on the American Prairie reserve roams at sunset on October 18, 2018, in Montana

The Bison Is America’s National Mammal. Here’s How Indigenous Tribes and Conservationists Aided Its Return to the Prairies After Near Extinction

The past, present and future of the giant bovine are front and center in a new exhibition as the country approaches its 250th birthday

Timmy the Whale Was Released Into the North Sea After Being Stranded Off the German Coast for Weeks. Was That the Right Call?

The humpback whale first entered shallow water at the end of March, but its health deteriorated over the past few weeks. Experts have criticized efforts to rescue the animal, which may have done more harm than good

About 47 percent of wolves in Italy are considered wolf-dog hybrids, according to a recent genetic analysis.
