Hikers often experience a powerful sense of accomplishment after finishing a difficult trail, and 71-year-old Jon Anderson was no exception. In September 2022, Anderson completed one of the toughest hikes out there—the 2,650-mile Pacific Crest Trail, which stretches from the U.S.-Mexico border to Canada. He carried over 20 pounds of supplies on his back throughout the journey.
According to the Backpackers Magazine, the Pacific Crest Trail, also known as the PCT, is the second-longest of America’s Triple Crown long trails, stretching from Mexico to Canada through the states of California, Oregon, and Washington. The adventure is a long-term commitment that takes about 4 to 6 months to complete. The journey of the old man, nicknamed Pa’at, reached completion alongside two fellow hikers, Auti and Chris, who documented his last steps to the finish line. They shared a short clip of the moment on their Instagram page @humping_north. The clip was shared over multiple social media platforms and soon went viral. The couple admired the old man’s endeavor and wrote, “Pa’at reaching the northern terminus of the Pacific Crest Trail after having walked every single step of the 2,653-mile trail. Not many people can say they’ve accomplished such an incredible feat – especially not at 71!”

After crossing the finish line, the man started singing a song that he had penned down during his trek. “Walking such a long way. Such a long way, just to be here, just to be here. Across deserts. I walked through rivers, I climbed mountains, just to see you. Just to see you. I’ve been waiting. Such a long time.” Auti and Chris, who also completed the PCT, wrote that they didn’t meet Pa’at until Stehekin, only 80 miles from the northern terminus, so they only knew him for a few days before finishing. Adding to this, they wrote, “He’s one of those people you instantly feel like you’ve known a lifetime. He has a heart of gold, the kindest soul, and unmatched optimism and fortitude. Thank you for being such an inspiration to us, Pa’at!”
According to Outside Online, Pa’at, which means bighorn sheep in the native language of the Cahuilla, a tribe from Southern California, is just a trail name chosen by Jon. Jon chose the name after it was suggested to him by one of his friends. His five-and-a-half-month journey started on March 17 and ended on August 30, and his wife walked alongside him for the first 1,800 miles. Talking about his song, Jon from Corvallis, Oregon, told Outside Online, “That song I sang was the pent-up emotion in me for my journey, but it was also the song for everybody else who walked. They weren’t as old as me, most of them, or none of them, but it was hard for them, too.”

Jon also reported that before he set out on the PCT in March, he settled into a daily routine. He would wake up in the dark, around 4:00 a.m. He would pack his belongings under the light of a headlamp, skip an early meal, and instead hike until he got hungry. Each day he walked at least 18 miles, occasionally stretching it up to 25 miles. During the hike, he often posted detailed photos of what he noticed on the trail for his family and friends to see. These included sights such as bright orange mallow flowers, white blooms of datura, a lengthy gopher snake, and more. During the trek, he even suffered from snowblindness on one occasion. “I hardly slept because the pain was so excruciating,” he says. “It wasn’t just the pain, it was also the fear; I was afraid that I had damaged my eyes for the rest of my life,” he recalled. Jon arrived at the Canadian border on August 30, smudged with mud and singing melodious tunes. Sharing his two cents for young backpackers, he says, “One foot in front of the other will take you a long way.”

But it wasn’t until the 1960s that methodical research into dolphin communication began. Scientists like John Lilly and the husband-and-wife team of Melba and David Caldwell tried various experiments to decipher the sounds dolphins can make.
The Caldwells figured out a way to record isolated animals in human care. They discovered that each individual dolphin communicated mostly with one unique whistle, which they called the “signature whistle.” Researchers now know that these whistles convey identities much like human names do. Dolphins use them to stay in touch with each other in their murky habitat, where vision is limited. It’s like announcing “I’m over here!” when someone can’t see you.
This collaborative study, led by Randall Wells of Brookfield Zoo Chicago’s Sarasota Dolphin Research Program, involves numerous researchers from a variety of institutions, who study different aspects of dolphin biology, health, ecology and behavior. Begun in 1970, this is the longest-running research project on a population of wild cetaceans – whales, dolphins and porpoises – in the world.

Experienced researchers can sometimes identify them by sight in the field, and they photograph them to confirm their identity in the lab.
Recording and observing
Researchers know the age, sex and maternal relatedness of almost all of the approximately 170 dolphins in the Sarasota community. This depth of knowledge provides an unprecedented opportunity to study communication in a wild cetacean species.
The dolphins in the Sarasota project are periodically subject to brief catch-and-release health assessments, during which researchers, including me, briefly handle individual dolphins.
Our team attaches suction-cup hydrophones directly onto each dolphin’s melon – that is, its forehead. We then record the dolphins continuously throughout the health assessments, taking notes on who is being recorded when, and what is happening at the time.
This is how my colleagues and I were able to confirm that wild dolphins, like captive animals, produced large numbers of individually distinctive signature whistles when briefly isolated from other dolphins. Through observations and recordings of known free-swimming dolphins, we were further able to confirm that they produced these same signature whistles in undisturbed contexts.
We have organized these recordings into the Sarasota Dolphin Whistle Database, which now contains nearly 1,000 recording sessions of 324 individual dolphins. More than half of the dolphins in the database have been recorded more than once.
We identify each dolphin’s signature whistle based on its prevalence: In the catch-and-release context, about 85% of the whistles that dolphins produced are signature whistles. We can identify these visually, by viewing plots of frequency vs. time called spectrograms.

Signature whistles and ‘motherese’
The Sarasota Dolphin Whistle Database has proved to be a rich resource for understanding dolphin communication. For instance, we have discovered that some calves develop signature whistles similar to those of their mothers, but many do not, raising questions about what factors influence signature whistle development.
Dolphin mothers modify their signature whistles when communicating with their calves by increasing the maximum frequency, or pitch. This is similar to human caregivers using a higher-pitched voice when communicating with young children – a phenomenon known as “motherese.”
Also similar to humans is how dolphins will initiate contact with another dolphin by imitating their signature whistle – what we call a signature whistle copy. This is similar to how you would use someone’s name to call out to them.
Our team is interested in finding out if dolphins also copy whistles of others who aren’t present, potentially talking about them. We have seen evidence of this in our recordings of dolphins during health assessments, which provide a rare context to document this phenomenon convincingly. But we still have more work to do to confirm that these are more than chance similarities in whistles.
Shared whistle types
Another exciting development has been our recent discovery of shared whistle types — ones that are used by multiple animals and that are not signature whistles. We call these non-signature whistles.
I could hardly believe my ears when I first discovered a repeated, shared non-signature whistle type being produced by multiple dolphins in response to sounds we play back to them through an underwater speaker. We had previously believed that these non-signature whistles were somewhat random, but now I was hearing many different dolphins making a similar whistle type.
Our team originally had been using the playbacks to try to determine whether dolphins use “voice cues” to recognize each other – similar to how you can recognize the voice of someone you know. Although we found that dolphins did not use voice cues, our discovery of shared non-signature whistle types has led to an entirely new research direction.

So far, I’ve identified at least 20 different shared non-signature whistle types, and I am continuing to build our catalog. We are hoping that artificial intelligence methods may help us categorize these whistle types in the future.
To understand how these shared non-signature whistle types function, we are carrying out more playback experiments, filming the dolphins’ responses with drones. We’ve found that one such whistle often leads the dolphins to swim away, suggesting a possible alarm-type function. We have also found that another type might be an expression of surprise, as we have seen animals produce it when they hear unexpected stimuli.
More difficult, more interesting
So far, the main takeaway from our experiments has been that dolphin communication is complex and that there are not going to be one-size-fits-all responses to any non-signature whistle type. This isn’t surprising, given that, like us, these animals have complicated social relationships that could affect how they respond to different sound types.
For instance, when you hear someone call your name, you may respond differently if you are with a group of people or alone, or if you recently had an argument with someone, or if you’re hungry and on your way to eat.
Our team has a lot more work ahead to sample as many dolphins in as many contexts as possible, such as different ages, sexes, group compositions and activities.
This makes my job more difficult – and far more interesting. I feel lucky every day I am able to spend working on the seemingly infinite number of fascinating research questions about dolphin communication that await answers.
Gavin, with help from aquarium staff, had secretly planned to propose right in front of the beluga whale tank. As he got down on one knee, a whale named Qinu swam into view.
The 16-year-old marine mammal paused right at the glass and appeared to drop her jaw in shock.
I’ve been interning with the beluga training team for the last 3 months so this was the most thoughtful way he could’ve done it 🥺 #georgiaaquarium#belugawhale#proposal
The moment was caught on video, and when Olivia shared it on TikTok, the comment section exploded. It looked exactly like the whale was gasping at the size of the ring.
“The most perfect proposal I could’ve asked for,” Olivia wrote.
Viewers immediately anthropomorphized the whale’s hilarious expression.
“The beluga NEEDS to officiate the wedding now,” one user joked.
Another simply commented: “The beluga: :O”
Even the official Play-Doh account chimed in to insist that the whale deserved a wedding invite.
According to People, Qinu’s involvement wasn’t a planned stunt. Katie Lorenz, the associate curator of mammals and birds at the Georgia Aquarium, confirmed that the reaction was entirely natural.
“Qinu’s behavior at the window was her own,” Lorenz said. “She was not intentionally trained to have any type of reaction.”
Unlike many other whales, belugas have unique physical characteristics that allow for this kind of “human” expression. They have a flexible neck and unfused cervical vertebrae, which allows them to nod and turn their heads.
Furthermore, their “melon” (the rounded forehead) is flexible and capable of changing shape, which often makes them appear to be smiling or making faces.
The moment was even more poignant because Olivia wasn’t just a random visitor. She had actually been a beluga whale training intern at the aquarium for the past three months.
“My fiancé is the most thoughtful person,” she wrote in a reply. “He knows how much I’ve loved working with the whales and truly made it the most special moment.”
The Conversation
Of course, viral videos involving captive animals often spark debate. Some commenters questioned the ethics of keeping an animal like Qinu in a tank.
“Nothing cute or adorable about these sentient creatures being kept confined in glass houses for human amusement,” one user wrote.

However, for the vast majority of viewers, the video was a moment of pure joy. The clip has racked up over 7 million views on TikTok alone, and Qinu has officially become the internet’s favorite wedding crasher.
For those who want to see more of the star, the Georgia Aquarium maintains a live beluga cam where fans can check in on Qinu. As for the happy couple, they now have a proposal story that is going to be very hard to top.

During mating season, male gentoo penguins are tasked to find pretty and smooth rocks to present to prospective mates. This is meant as a gesture to woo them and to be used to build a nest with them, too. Well, this season, the penguins at the Edinburgh Zoo in Scotland got some help.
Kids being supported by the Edinburgh Children’s Hospital Charity gathered together to paint pebbles with vibrant colors for the penguins. The hospitalized children do this every year with the first stone traditionally placed in the penguin enclosure. The children often watch a livestream of the gentoo penguin enclosure to see the penguin pick their favorite rocks that they’ve painted.
The Edinburgh Zoo posted this year’s pebbling pickings on Instagram, delighting the commenters:
“I would cry if a penguin picked MY pebble 😭 It’s a life goal lol.”
“This is just brilliant! How wonderful to see a creative health initiative that actively connects the children with a purpose like this!”
“This is heartwarming ❤️❤️❤️”
“This is brilliant for the penguins and the children! Can’t wait to see the beautiful nests.”
“My grandson painted a pebble he’s hoping it gets picked.🤞🤞🤞”
“Penguin pebble pilfering season is upon us! So pleased it makes so many people (and penguins) happy.”
“Oh no, now I’m questioning if penguins have favourite colours.”
“Any that aren’t picked would make an awesome rock garden that kids visiting the zoo could pick from!!”
“This is the cutest thing I have seen probably ever.”
Pebbling practices for human relationships
As mentioned, this mating ritual called “pebbling” is a gesture made by male penguins to their mate to not just build a nest. It’s their version of saying, “I saw this and I thought of you.” In fact, psychologists and couples therapists recommend adopting a version of pebbling for human relationships.
Now to “pebble” in dating or married relationships doesn’t literally mean giving your partner rocks (unless they’re a geologist that would love that sort of thing). For humans, pebbling your partner means to share or give a small gift like a flower, toy, or object that has some meaning to one or both of you. It doesn’t always have to be a gift either, but it could be a photo, social media post, or a meme you can text them. It’s essentially anything that conveys “I saw this and thought of you” in order to showcase affection to them and initiate closer conversations.
Pebbling isn’t just for romantic couples either. Many autistic people find it more difficult to navigate socially due to high anxiety, sensory sensitivities, or having trouble interpreting social cues. By texting a GIF to a friend, giving a small flower to their parent during a walk, or other such pebbling, it allows some autistic people the ability to communicate their affection and connection without the pressure of using words.
Whether it’s a colorful rock or something else, pebbling can be a valid form of communication between friends, partners, or potential mates. It all depends on who you choose to build a nest with.
