Claude lived at the California Academy of Sciences for 17 years and became a beloved celebrity.

Claude, San Francisco’s Beloved Albino Alligator and ‘Unofficial Mascot,’ Dies at Age 30

Veterinarians will conduct a full exam and necropsy to determine the cause of death, but Claude had been undergoing treatment for a suspected infection in recent weeks

For the study, the researchers worked with two adult male macaques that had previously been trained to tap in time with a metronome.

These Monkeys Learned to Tap to the Beat of the Backstreet Boys. Can They Teach Researchers About the Origins of Human Musicality?

Two macaques learned to keep time with various songs, which might point to how humans got their sense of rhythm. But some scientists doubt that the primates’ feat, which required extensive instruction, can give evolutionary clues

The unfamiliar monk parakeets got to know each other slowly before moving on to behaviors like preening, pictured here.

Monk Parakeets Are Highly Social Birds, but They Slowly ‘Test the Waters’ When Making New Friends

The bright green parrots start with low-cost social behaviors—like sitting near each other without touching—when first interacting with unfamiliar birds within their species, possibly to avoid aggressive encounters, new research suggests

Genetic analyses revealed some of the winding paths behind the spread of domestic cats.

When Did Domestic Cats Take Over the World? New Research Suggests They Arrived in Europe and China Centuries Later Than We Thought

Two genetic analyses suggest that our feline friends reached China around 1,400 years ago via the Silk Road, and that they traveled from North Africa to Europe around 2,000 years ago

A male golden pheasant (Chrysolophus pictus) with its vision-obscuring head feathers. 

For Some Male Pheasants, Love Really Is Blind. Their Elaborate Feathers That Impress Females Also Obstruct Their Vision

The adornments on the heads of male Lady Amherst’s and golden pheasants partially block their sight, according to new research, marking the first known sex-based differences in field of vision within bird species

Pigeons can sense magnetic fields via their inner ears, new research suggests.

Pigeons Rely on the Earth’s Magnetic Field to Navigate. Now, Researchers May Have Uncovered How They Do It

The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ability

The new research may help scientists and conservationists better monitor African lion populations. 

Listen to a Lion’s Second Type of Roar, Which Was Just Discovered by Scientists

Researchers uncovered the previously unknown vocalization while creating an algorithm that can identify and monitor lions based on audio recordings

European starlings were the best at imitating R2-D2's multphonic sounds because they can control both sides of both sides of the syrinx independently, the researchers say.

Birds Are Beeping and Booping like R2-D2. Their Mimicked Sounds Are Helping Unlock the Secrets of Avian Communication

European starlings were better than parrots at imitating R2-D2’s high-pitched chattering, possibly because of their special control over a vocal organ

Chimpanzees, like some other apes, kiss each other on the lips. 

How Did Humans End Up Smooching on the Lips? It May Have Started Out With a 21-Million-Year-Old Kiss

Our ancient primate relatives—including Neanderthals—may have enjoyed a nice peck on the lips. But researchers still don’t know why we do it

Seabirds are just some of the marine animals known to eat plastic. 

More Than 1,200 Marine Animal Species Eat Plastic. Ingesting Even a Tiny Amount Can Kill Them, a New Study Suggests

Researchers examined more than 10,000 animal autopsies to figure out how much plastic is too much for ocean wildlife

Two new studies explored the impact beavers have on bats and pollinator insects.

Beavers are Dam Good for Biodiversity, Bringing Bats, Butterflies and Other Critters to Their Neighborhoods

Two new studies suggest that the semi-aquatic rodents provide food and habitat for bats and pollinator insects within their engineered ecosystems

Members of the Haíɫzaqv (Heiltsuk) Nation caught the crafty female wolf on camera.

Watch a Wolf Cleverly Raid a Crab Trap for a Snack. It Might Be the First Evidence of a Wild Canid Using a Tool

Footage from British Columbia shows just how intelligent wild wolves can be, but scientists are divided as to whether the behavior constitutes tool use

Elephant seals on South Georgia island

Bird Flu Wiped Out Nearly Half of the Females in the World’s Largest Elephant Seal Population, Drone Images Suggest

Scientists recorded a 47 percent drop in breeding females in South Georgia’s three largest elephant seal colonies after bird flu hit. Scaled to the whole island, that’s a potential loss of more than 50,000 of the animals

Chubby the macaw arrived with self-plucking injuries, which are typically caused by stress, boredom, anxiety or life changes. Chubby was 22 at the time of being photographed in 2025, and she has since been adopted.

The Nation’s Biggest Animal Sanctuary Operates Under a Mantra to ‘Save Them All.’ How Could That Be Controversial?

Best Friends Animal Society has a sprawling campus in the canyons of Utah, but its influence has grown to reach almost every shelter in the country

Amabala, a 5-year-old female who was born in captivity, is raising four healthy cubs.

Watch Four Furry and Adorable Cheetah Cubs on the Smithsonian National Zoo’s Online Feed

The “strong, active” and “vocal” babies were born during the government shutdown, and they and their 5-year-old, first-time mother, Amabala, are thriving

Tiny but mighty: Downy woodpeckers drill into trees with a force 20 to 30 times their body weight.

Downy Woodpeckers ‘Grunt’ as They Turn Their Bodies Into Hammers to Drill Into Trees

Researchers studied the combination of muscles and breaths that the tiny birds use as they strike trees with their beaks

The specimen was discovered in Western Australia. 

This Newly Discovered ‘Lucifer’ Bee From Australia Was Named After Its Devil-Like Horns

Researchers hope the discovery shines a light on bee conservation Down Under

More than 200 river dolphins died in Brazil's Lake Tefé in the fall of 2023, with water temperatures soaring as high as 105.8 degrees Fahrenheit, according to a new study.

Water Temperatures in Amazon Lakes Reached Hot Tub Levels in 2023, Killing Fish and Dolphins

Brazil’s Lake Tefé reached 105.8 degrees Fahrenheit during the severe drought and heat wave

Eastern hellbenders are known as "snot otters" because they're covered in a slimy, protective coating.

Scientists Are Releasing the Lovingly Nicknamed ‘Snot Otters’ Into Ohio Waterways in a Big Success for Conservation

Eastern hellbenders, the largest amphibians in North America, are in trouble, but conservationists are hard at work to help the wrinkled wonders survive

Iguanas Are Native, Not Invasive, on This Mexican Island, DNA Study Suggests, Rewriting Conservation Ideas

The spiny-tailed iguanas of Clarion Island predate human presence in the Americas by tens of thousands of years, researchers say
