An old male bald eagle who adopted a rock as an egg finally got his own real foster baby

Murphy became a real dad after he spent weeks nurturing his "RockBaby."

Murphy meets a rescued eaglet—his new foster baby.

On March 8, 2023, a keeper at World Bird Sanctuary in St. Louis County, Missouri, noticed something odd. A male bald eagle named Murphy was guarding what appeared to be a large depression in the ground. “The spot was sparsely but carefully decorated with leaves and branches, and featured a simple rock right in the center,” the nature preserve shared on its Facebook page.

Murphy began sitting on the rock, nudging it and becoming fiercely protective of it, as it if were an egg. People visiting the sanctuary would inquire about the bald eagle just sitting there, wondering if he was okay. The keepers finally put up a sign that read:

“If you see an eagle lying down in the back left corner under a perch, that’s Murphy! Murphy is not hurt, sick, or otherwise in distress. He has built a nest on the ground, and is very carefully incubating a rock! We wish him the best of luck!”

In case you’re wondering if this is unusual behavior for a 31-year-old male bald eagle, the answer is "not really, but…." Male bald eagles do share equally in nesting and baby-raising, so the paternal instinct part is normal. Murphy's channeling of that instinct onto a rock…maybe not so much. And at 31, he's more like a great-granddad than dad, as bald eagles usually live 20 to 30 years in the wild (though they do live longer in captivity).

Murphy takes fatherhood seriously, though. Soon he began screaming and charging at the four other eagles in the aviary if they came anywhere near RockBaby. (That's the official name the keepers gave Murphy’s…well, rock baby.) Naturally, the screaming and charging caused a fair amount of stress for all involved, so Murphy and RockBaby were moved to their own enclosure for everyone's protection.

People who saw this unfold started suggesting sanctuary staff replace Murphy’s rock with a real egg or get him a mate, but 1) Eagle eggs aren’t just lying around waiting to be given to wanna-be dads, 2) hatching a different kind of bird's egg would be potentially dangerous for it, and 3) Murphy had two females right there in the aviary, and none of them were interested in each other. Alas, the heart cannot be forced.

However, a different opportunity presented itself in late March when an aerie with two chicks in it was blown down by high winds. One chick didn’t survive the fall, but the other was brought to World Bird Sanctuary’s Wildlife Hospital.

A bit bruised, but otherwise healthy, the chick was given a good prognosis. Staff began feeding it while wearing a camouflage suit and holding an eagle stuffy to prevent the eaglet from imprinting on humans. What the baby really needed was a foster parent—an adult eagle who would feed and care for it.

“Murphy’s dad instincts were already in high gear,” the sanctuary wrote on April 11, “but at 31 years old, he had never raised a chick before. It’s definitely a gamble, but also the chick’s best chance.”

Introducing an eaglet to an adult eagle isn’t as simple as dropping it in the enclosure. First, the eaglet is put into what the sanctuary refers to as a “baby jail," which is a heated, comfy cage made of wood and wire that protects the eaglet but still allows some interaction between the birds so they can get used to one another. Once the desired bonding behavior is observed, then they try out some direct one-on-one interaction without the cage.

On April 12, World Bird Sanctuary announced, "IT'S HAPPENING!!!!"

The eaglet (referred to as Bald Eaglet 23-126—they don't name foster babies at the sanctuary for superstitious reasons) was released from baby jail, and after an hour or so Murphy approached it with curiosity. Was he wondering if his RockBaby had hatched? Maybe. Would he be the nurturing dad everyone hoped he would be? It appears so.

As the sanctuary shared:

"This morning, Murphy got his chance to be a full parent as 23-126 left the nest to go be closer to Murphy. The food is being dropped through a blind drop tube into the nest and baby appears unable to be able to get over the lip to get back into the nest to get the chopped food. When we checked back, we found that baby was still out of the nest and all the chopped food was still in the nest. However, Murphy’s whole fish had been removed from the nest and baby had a full crop. 23-126 is not yet old enough to tear food which means MURPHY FED THE BABY!!!!"

The comments on the update, of course, were pure gold as people became fully invested in this story and even gave the eaglet a real name—Dwayne, as in The Rock:

"I can’t believe I’m crying over eagles!"

"Murphy’s going to be giving a TedTalk: Manifest The Eaglet You Need In Your Life."

"So happy for Murphy & eaglet Dwayne (the rock Johnson)."

"'Rock, I am your Father.'"

"Omg I’m crying! Murphy never gave up on his rock and now has a baby of his very own❤️The wonders of nature never cease. Ty, WBS, for making this possible. These two are saving each other❤️🦅❤️🦅🪨🐣."

Many people lamented that there is not a live cam at the facility so people could watch this pair as their relationship developed, but staff reminded everyone that the sanctuary is out in the middle of the woods and they don't have a strong enough signal for a live stream. But WBS staff posted regular updates on social media on how Papa Murphy and "Dwayne" were doing.

Murphy was honored on Father's Day for his stellar fostering skills as he returned to the aviary:


"We'd like to thank Murphy for his service and applaud his outstanding job in raising 23-126," the sanctuary wrote. "Murphy may have had a few moments in his parenting duties where he regretted choosing to sit on that rock, but we believe that the overall experience has been very enriching for him. We know that Murphy has enriched 126's life. Thanks to Murphy, 126 has grown up knowing that he is a Bald Eagle! 126 has learned so much from Murphy and, thanks to his efforts, will have a much greater chance of thriving in the wild after he is released. Happy Father's Day Murphy, and thank you, we couldn't have done this without you."

Sadly, Murphy passed away at age 33 in March of 2025, after having fostered two eaglets in his final years. He lived a long life for a bald eagle and the World Bird Sanctuary offered a beautiful tribute to his extraordinary bird.


"His resilience, spirit, and dedication as a foster dad touched the hearts of millions of people throughout the world, leaving an especially profound impact on those fortunate enough to have worked with him. While Murphy has delighted guests along Avian Avenue for years with his distinct vocalizations and charismatic personality, it wasn't until 2023 when he decided to incubate a rock that he gained an international following. Murphy's transition from rock incubating to rockstar foster dad of an injured eaglet brought daily joy to thousands as we watched their journey together. As Murphy's eaglet grew so did our love of him. Their journey together taught thousands about eagle growth and development, the bonds between eagle parents and their young, and the critical work that goes into wildlife rehabilitation. Murphy's eaglet continued to grow strong under his watchful gaze and went on to be released back to the wild. The following year, Murphy fostered a second eaglet in need with the same dedication he gave the first. His second eaglet is still in our care, but is making good progress toward release and we expect he will be ready by mid summer.

We could not have asked for a better ambassador and role model. We are incredibly grateful for the community that came together as a result of his heartwarming story. We are devastated by this loss and know that the community mourns with us. Murphy's foster eaglets were the first ones our hospital received in over a decade and we learned a lot about their care and space needs from observing Murphy with them. With what we learned from this, we've designed a series of special aviaries to serve the specific needs of injured and orphaned raptors, including an aviary specialized for eaglets. In honor of Murphy's legacy, we plan to name the eventual eagle fostering aviary Murphy's Manor, so that we can continue to remember him for decades to come. Murphy will be deeply missed, but his legacy will live on in the memories of those who loved him."

Rest in peace, Papa Murphy.

A scientist created a 'utopia' for mice and then they all started dying

The results are fascinating, but are they relevant to humanity?

How could Mouse Heaven go so terribly wrong?

In 1968 John Calhoun, a scientist and animal behavioralist, decided to create a "utopia" for mice. It would have unlimited food and water, with beautiful nesting spaces and plenty of materials for the mice to make cozy homes with. Sweet experiment! the mice were probably thinking. Much better than the Maybelline trials we're used to.

However, there was a catch, of course. There was one thing the utopia would be lacking, and that would be physical space. As the mouse population grew, overcrowding would become an issue, and Calhoun wanted to study the problems this would potentially cause. That sound you hear is the collective sigh of the disappointed mice who were stoked about the 24/7 all-you-can-eat buffet.

The experiment, dubbed Universe 25, began when Calhoun introduced four mouse "couples" into the utopian complex. A year or so later, it was overrun and the conditions had turned hellish, even though the mice had not run out of food or water.

Initially, for just the eight original mice, the square box Calhoun built included 256 nesting boxes (or apartments) stacked on top of one another. Water bottles and food dispensers were located all along the nesting spots, and mice could travel throughout the complex at will via mesh tunnels. The starter mice were also screened for diseases and the population was obviously protected from predators. The climate was controlled and comfortable. Conditions were perfect.

The first mouse pups showed up a little over three months later, with the population of the colony doubling every 55 days. Nineteen months later, there were 2200 mice living inside the box. With such perfect surroundings, the infant mortality rate was practically zero, leading to the rapid rise in numbers.

By month 19, this rodent utopia had become an overcrowded hellscape. Calhoun noticed three alarming trends, in particular.

In short, everything was devolving into chaos and the very society of the mice began to collapse at a rapid rate.

The "Beautiful Ones" and the "Dropouts": Mice have a complex social hierarchy ruled by dominant alpha males. Sam Kean of Science History Institute Museum & Library notes that, in the wild, non-dominant males (the ones who lose macho showdowns) can skip town and start over somewhere else. But in the close quarters of Calhoun's experiment, with nowhere to hide, they were forced to hang around and viciously battle with each other over scraps. Eventually, non-dominant male mice, which Calhoun called the "Beautiful Ones," withdrew from society completely and only ate, slept, and groomed themselves.

Though resources were unlimited, certain aggressive males hoarded them anyway: The alpha males ruled over everything in the once-utopian mouse society. They kept harems of females in the apartments to mate with and fought fiercely to defend their territory. But new waves of hungry young male mice kept coming and coming, and eventually even the most dominant alphas abandoned their posts. This led to more attacks on nursing females, which in turn led to more mothers kicking their pups out of the nest early.

Birth rate declined dramatically: With the non-dominant males giving up completely and focusing on #SelfCare, dominant males too exhausted from endless battles, and females sick and tired of it all (many became asexual hermits by the end), stopped mating and giving birth entirely. Once this happened, the society was doomed. Even with plenty of food still available, cannibalism was rampant.

Calhoun was not shy about drawing parallels between his research and humanity. "I shall largely speak of mice, but my thoughts are on man, on healing, on life and its evolution," he once wrote.

There are aspects of his wild experiment that certainly sound familiar.

We live in a world with plenty of resources for everyone, but a few select people hoard more than their fair share. When you think of the rodent "apartments," it's hard not to picture densely packed urban environments where people are stacked on top of each other at every turn. Maybe on some level some of us can relate to the “Beautiful Ones” and their urge to not participate in all the ugliness and just sequester and groom themselves. You can make an argument that when the mice stopped having to worry about food and shelter, it removed the element of challenge from their lives and left them lost–like many of us are lucky enough to not have to wonder where our next meal comes from, and maybe that has something to do with our never-ending search for meaning. Some even go so far as to link more people choosing to delay having children, or not have children at all, with the collapsing society of the mice.

But Calhoun's work has also been heavily scrutinized, with some claiming it's based on shaky science. And in the end, there’s the small matter that humans are not mice. We are infinitely more complicated, and so much better suited to adapting to our environments. Kean writes, "Ultimately Calhoun’s work functions like a Rorschach blot—people see what they want to see."

It's fascinating and thought-provoking nonetheless.

Mama orangutan's tender moments with her 3-month-old baby melt everyone's hearts

Such a good mama.

Toronto Zoo/YouTube

Mama Sekali takes good care of her 3-month old.

There's nothing like the magic of new motherhood, when you find yourself spending hours marveling at the incredible being you helped create and gazing at their impossibly tiny and adorable features. It's sweet when humans do it, but seeing animals have those kinds of tender moments with their babies is so endearing.

Sekali, a Sumatran orangutan who lives at the Toronto Zoo, gave birth to a baby in April 2022. In a video shared by the zoo, the baby gets some "tummy time" while Sekali gently strokes and cuddles him. "Sekali continues to take excellent care of her little one, and he appears to be more alert and mobile," the zoo shared. "Keepers are seeing the baby standing up while holding onto mom and sitting up on his own now, so he is growing stronger each day."

The little guy is cute cute cute, but Sekali picking up his foot and "kissing" it is the sweetest darn thing ever.

People gushed over the video on the zoo's Facebook page.

"LOOKS LIKE ALL MOMMA'S COUNTING THOSE LITTLE TOES AND FINGERS.... SHE APPEARS TO BE SUCH A TENDER MOM!! 🙂❤ I LOVE THIS!!!! 🙂" wrote one commenter.

"Clearly his Mom just adores him so much," wrote another. "She is such a good Mom.........he's so sweet and bright-eyed .....a happy and content little guy."

"I’m going to get in trouble for saying this, but, that little one is cuter than a lot of babies!!!! Just look how gentle she is with baby!!!" shared another.

A few months later in August 2022, the Toronto Zoo announced in a press release that the baby orangutan had been christened "Wali," which means "guardian" in Indonesian. Dolf Dejong, CEO of the Toronto Zoo, noted that the name was chosen from a batch of suggestions from the Wildlife Care keepers. Though there were many great suggestions, one stood out as the "clear winner," said DeJong. According to the Zoo's press release, the name felt "fitting since Sumatran Orangutans are the guardians of the rainforests."

While the Sumatran orangutans are seen as guardians, the sad truth is that the species is in trouble.

In 2017, Sumatran orangutans were moved from the International Union for Conservation and Nature (IUCN) Red List of Threatened Species' "endangered" category to "critically endangered," with their habitat in the wild threatened by deforestation, primarily due to palm oil plantations replacing rainforests. According to the Sumatran Orangutan Conservation Programme in 2022, there were only around 14,000 orangutans left in the wild. According to the World Wildlife Fund (WWF), that number has dipped even lower as of 2025.

Orangutan breeding in captivity is not without its controversy, however. The purpose of captive breeding programs like the Orangutan Species Survival Plan is not to release the animals into the wild, but rather to maintain genetic diversity, enable research, and educate the public about these magnificent creatures. Zoos have come a long way in recent decades, creating habitats that look and feel much less like cages and more like the wild, and studies have shown that zoos have a positive impact on people's interest in conservation. Orangutans in human care, like Sekali, may help motivate more people to care about what's happening to the species in their home habitats.

“We are incredibly excited to welcome this new addition to the Toronto Zoo family,” said DeJong. “This orangutan baby is an important contribution to a genetically healthy Sumatran orangutan population in human care. Meanwhile, Sumatran orangutans are under increasing pressure in the wild due to habitat loss and the palm oil crisis, which we are working with partners to address. We are proud to play an important role in the conservation of this amazing species.”

Today, Wali is thriving with mama Sekali and dad Budi. A compilation of his "adorable antics" was shared on YouTube in early January, showing the public what Wali has been up to the last few years. Watch:

Forget what you know about bed bugs. Avoiding and getting rid of them is pretty simple.

And thankfully, there are no toxic chemicals involved.

Mark Rober/YouTube

Mark Rober subjected himself to bed bug bites in the name of science.

"Good night! Sleep tight! Don't let the bed bugs bite!" This sing-songy rhyme that has been around for centuries alludes to the fact that bed bugs were prevalent in the past. After a significant decrease post-WWII, however, the sneaky pests have been making a comeback. Since the 1990s, bed bug infestations have risen dramatically, leading people to look for ways to avoid and get rid of the blood-sucking little buggers.

Unfortunately, a lot of the information about how to do that is flat-out wrong. Popular YouTube science communicator Mark Rober invites viewers to forget what we think we know and go on an educational journey with the leading bed bug researchers at Rutgers University's urban entomology lab. Not only did Rober subject himself to bed bug bites on purpose to see what happens when they feed, but he also conducted a series of experiments in the lab to find out what is actually effective at killing them and what is not.

Bed bugs have a reputation for being nearly impossible to get rid of, which isn't really the case, according to Rober. When you know what works, it's actually a fairly simple process to kill an infestation. And the good news is that it doesn't entail any toxic chemicals—in fact the pest control chemicals sold for bed bugs don't work at all, according to Rober's tests.

In the process of learning about bed bugs, Rober shared a few "super wild" facts about the infamous creatures.

Fact #1: Bed bugs can live 3 to 10 months without feeding.

Eek. No wonder it seems like it's impossible to get rid of them. Starving them doesn't work. They can live in the resting stage for 3 to 6 months, and if the environment is cold enough, they can survive around 300 days, or 10 months, without eating.

Fact #2: Bed bugs don't transmit disease

Some good news here: Unlike blood-sucking mosquitoes, bed bugs don't carry or transmit disease. The bad news on the front is that because they don't pose a disease threat, only an annoyance, there's not a big incentive to fund research to eradicate them.

Fact #3: Bed bugs are attracted to vertical objects

In one of Rober's experiments, he placed a dish with a cylindrical vertical post inside it an a dish without a column, and nearly all of the bed bugs in the enclosure ended up in the dish with the column. "If you think about it, humans sleep at the highest elevation any given room. So their logic is just crawl up any vertical surface you see until you eventually find a warm-blooded meal at the top."

Part of how they find humans is by smell, which is why certain strong-smelling items can act as a deterrent for bed bugs. In Rober's experiment, Bounce dryer sheets, moth balls, baking soda, and essential oils all seemed to repel bed bugs (as opposed to ultrasonic pest repellers, which appeared to have no effect). However, none of those things did anything to kill them.

Fact #4: Before 1950, one in three homes had bed bugs

Yikes. Even with the resurgence, we're still nowhere near those numbers, thank goodness.

Fact #5: The way bed bugs mate is weird

The term used to describe it is called "traumatic insemination," and really, you should just let Mark Rober explain it with his visual metaphor. Start at minute 11:30.

Two things work well to kill bed bugs—diatomaceous earth and heat

In testing chemical sprays, foggers, and other items marketed for killing bed bugs, Rober found a "superstar" in a natural, non-toxic substance. Diatomaceous earth—pulverized fossilized remains of tiny aquatic organisms called diatoms—was the most effective at killing the buggers with a 90% mortality rate after 10 days as opposed to 12% with the Hot Shot bed bug spray. Diatomaceous earth is mostly silica, which absorbs moisture, and when the silica dust sticks to the bed bugs as the walk through it, it dehydrates them. A light dusting of diatomaceous earth around all the cracks and crevices of a room is one way to kill off an infestation, though that process can take days.

The other way to kill bed bugs is heat. Steam kills bed bugs, as does heating up a room to over 122 degrees Fahrenheit does the trick. Temps over 122 degrees kills bed bugs instantly, and as Rober points out, there's no way for them to build immunity to this kind of treatment. So steamers and clothes dryers set to high are the average person's best bet for killing off bed bugs if they have them. The "nuclear option" is to have a pro come in with big heaters and cook your home for a day.

How do you avoid getting bed bugs in the first place?

An ounce of prevention is worth a pound of cure, and that's true for bed bugs especially. Avoiding an infestation if there's already one in your apartment building is trickier, but a lot of people inadvertently bring bed bugs home from hotel stays. Checking the underside of a hotel mattress as soon as you come in the room is a good habit to be in. Bed bugs poop a lot, and there will be spots along the edges of the mattress if bed bugs are present.

The other tip is to use the luggage rack to store your suitcase instead of leaving it on the floor or furniture and to hang clothes on the closet hangers instead of putting them into the hotel room's dresser drawers. Some people may even put their suitcase in the bathtub, at least until they've checked the bed for signs of poop.

Nobody wants to deal with bed bugs, but at least now we have clear evidence of what actually works to get rid of them and what doesn't. Cook them with heat/steam and dehydrate them with diatomaceous earth, and take some simple steps when traveling to lessen your chances of getting them in the first place.

Sleep tight, everyone!
