This Parrot Loves Earth, Wind And Fire

The last few decades have revealed birds like crows and parrots possess astonishing intelligence. “Bird brain” might not be much of an insult after all.

Meet Kiki the cockatiel, a bird who loves Earth, Wind and Fire so much that he sings the band’s classic hit, September, regularly — whether he’s just chilling by himself, singing along to the recording or driving his human crazy by whistling the catchy hook at ungodly hours.

“Kiki, it’s seven in the morning!” she tells him in one clip, raising an admonishing finger. “Silence!”

Partying without me 😦 #cockatielsoftiktok #birds #fyp #for you

♬ original sound – ✨ Kiki the cockatiel✨

Kiki regards her for moment as if her request is absurd, then launches right back into September.

Hey, hey, hey
Ba-dee-ya, say, do you remember?
Ba-dee-ya, dancin’ in September
Ba-dee-ya, never was a cloudy day

In another video Kiki’s human sets her phone to record and leaves the room, and Kiki busts out his favorite song again. He’s got great taste in music!

I’ve always thought parrots are a fascinating example of animal cognition and further proof that we share our planet with billions of other minds who think and feel.

Humans and birds last shared a common ancestor more than 300 million years ago. That means between them there’s been more than 600 million years of divergent evolution resulting in radically different physiology, abilities and minds.

Yet parrots can speak while non-human primates (apes and monkeys) cannot!

For decades scientists thought apes and monkeys, by virtue of their relative similarity to humans, possessed an inmate affinity for language and that the physical limits of their vocal apparatus is what keeps them from speaking.

But a 2016 study by a team from Princeton University found monkeys do possess the vocal “hardware” to speak, meaning their mouths and throats are capable of making the sounds necessary for human language. It’s the lack of associated brain circuitry that prevents them from talking.

If the ability to speak and the ability to dance/appreciate music and rhythm is uniquely human among the primate order, and birds arrived at it at a different point in their evolutionary history, that means language and appreciation for music/rhythm developed separately along two divergent evolutionary lines!

That’s incredible and has intriguing implications for the cognitive abilities of animals.

A common argument is that birds with the ability to form human speech are simply mimicking sounds and don’t understand what they’re saying. That’s a natural assumption given what we think we know about non-human capacity for understanding language, but research suggests it’s wrong.

Take a look at this video of the famous late African grey parrot, Alex:

When Dr. Irene Pepperberg asks Alex how many blue blocks are present on a tray with a random assortment of blocks, balls and triangular toys in different colors, Alex can’t give a rote answer. First he has to understand that a question is a request for information and not part of the strange human ritual called small talk. He can’t simply count or guess at the number of blocks either.

Instead, Alex has to perform two calculations. He must tally the blue objects and count the number of them that are blocks, or he’s got to count the number of blocks and figure out how many of them are blue.

If he was simply repeating information in context — like saying “Hello!” when a person walks into a room — Alex wouldn’t be able to correctly answer the questions, and Pepperberg’s research funding would have dried up. Instead, Alex became a focal point of research that persisted for decades.

There’s no indication Alex could master syntax, which has proven elusive for even the smartest animals. But the African grey, who died in 2007 at 31 years old, was curious, asking questions that were unique and unexpected of an animal. He once asked his caretakers to describe his physical appearance, and the night before he died, he told Pepperberg: “You be good. I love you. See you tomorrow.”

We’ve talked about parrots before on PITB, including Snowball the dancing cockatiel who not only appreciates music and has a great sense of rhythm, but also has an entire repertoire of unique dance moves. Then there’s my personal favorite, Ruby the African grey, who has demonstrated mastery of absolutely vile, uniquely British insults.

Sure, there may not be much research value in hearing Ruby hurl verbal abuse at her very loving human, Nick Chapman, but few things have made me laugh as hard as that extraordinarily foul-mouthed bird. She has to be seen and heard to be believed. (But if you’ve got kids in the room, stick with the wholesome Snowball. He’s got serious moves.)

Snowball the dancing parrot — Scientists credit Snowball with choreographing his own dance routines, with dozens of individual dance moves and combinations, and moves that change depending on the song he’s rocking out to.

Now if you’ll excuse me, I’m off to teach a certain feline a few Earth, Wind and Fire songs in the hope that he’ll give up on the screeching meows and use his natural falsetto for a more gentle wake-up experience.

Hey, hey, hey
Ba-dee-ya, hey there my Big Buddy
Ba-dee-ya, Little Buddy’s hungry!
Ba-dee-ya, get your lazy ass up and feeeeeed me!

Cat Domestication Was The Start Of A Beautiful Friendship

Domestication’s real goal: to make cats cuddly as well as great mousers.

Cats have been doing things their way since the very beginning.

Unlike literally every other domesticated animal, cats were not domesticated by humans. They did it to themselves.

As if that didn’t make them unique enough, they lay claim to another major distinction: they’re the only species of obligate carnivores to undergo domestication in the entire history of human existence.

That explains why cats, more than any other animal that depends on humans, so closely resemble the wild animals they were before signing up for the good life of naps, warmth, endless rodents to hunt and free food from their new human friends.

In a new essay for The Conversation, evolutionary biologist Jonathan Losos, author of The Age of Cats: From the Savanna to Your Sofa, notes new DNA analysis settles the question of where cats came from once and for all.

Domestic cats are descended from North African wildcats, specifically the species felis sylvestris lybica. Unlike dogs, who underwent telltale physical transformations when they evolved from wolves, house cats “appear basically indistinguishable from wildcats.”

“In fact,” Losos writes, “only 13 genes have been changed by natural selection during the domestication process. By contrast, almost three times as many genes changed during the descent of dogs from wolves.”

While the change in genetics that happen with domestication left cats pretty much as they were physically, the process made dramatic changes in the feline brain, reducing regions governing fear and expanding those related to social behavior. The result? The major difference between house cats and their wildcat ancestors is disposition.

In other words, domestication made cats cuddly.

Notably, felis sylvestris lybica had to be pretty friendly in the first place, as well as bold and driven by the now-legendary feline curiosity to risk padding into human settlements with their bright lights, strange smells, open flames and the two-legged giants striding around them.

They didn’t have a way of negotiating or signaling their intent. They couldn’t say: “Hey guys, we’re here to kill and eat the tasty rodents who have been giving you problems by chowing down on your yums, but we don’t want your yums for ourselves. Plants are disgusting!”

So they had to demonstrate their usefulness, prove their worth, and enjoy the fruits of it by curling up in front of warm fires or on human laps.

That explains why it was the African wildcat that became a human companion species and not European wildcats, whom Losos notes are often “hellaciously mean” in interactions with people, even if they’re raised around humans when they’re young. It was also a matter of being in the right place at the right time, as nascent human civilization took root in the Fertile Crescent.

But ultimately, just like cats decided to domesticate themselves and didn’t really bother to consult us about it, so too do they bend us to their will with an entire repertoire of manipulative behavior, from solicitation purrs to incessant meowing and having a talent for looking their cutest when they want something.

While we may think we set the rules and parameters of our relationship with the furry little ones, as Losos notes, “cats usually train us more than we train them.”

Feline evolution: How house cats and humans domesticated each other

Did A Japanese Scientist Really Double Feline Lifespans?

A new story claims a Japanese immunologist has “created a miracle” with his treatment for cats.

The cat world is abuzz with a new report that hails the efforts of a Japanese scientist, claiming he’s “created a miracle” that can extend cat lifespans to 30 years.

The story on Bored Panda claims the drug has “astounding potential,” boasting “a level of efficacy that has exceeded all expectations and has the potential to revolutionize feline healthcare.” According to Bored Panda, we’re headed toward a gleaming future and “soon we will be able to grow old with our beloved pets and be grey together.”

“Cat Lovers Rejoice As New Medicine Will Extend Cat Lifespan To 30 Years,” the headline declares.

Okay, let’s dial it back a bit and break down what’s true and what’s not.

First and most obvious, the story oversells the treatment and if you’re counting on your cat living to 30, you’ll need to readjust your expectations.

That’s unfortunate because there’s a good story at the heart of this, and there may be real benefits to cats eventually.

Toru Miyazaki is an immunologist who discovered a protein that helps the kidneys flush out toxins. Eight years ago, he realized the protein — apoptosis inhibitor of macrophage, or AIM — doesn’t always work properly in felines, which is why so many cats are susceptible to kidney failure, especially when they reach age 10 or so.

The AIM protein, Miyazaki explained, launches from immunoglobin antibodies “like a jet fighter from an aircraft carrier,” removing waste and debris from the kidneys.

But in cats, sometimes the AIM protein — the fighter jet — is “too tightly bound” to the antibodies, meaning it doesn’t “launch” in the first place and can’t do its job of flushing out toxins.

Miyazaki was continuing his research into feline kidney failure while he was a professor at the University of Tokyo, but funding dried up in 2020 as the lion’s share of research money in immunology was directed toward addressing SARS-CoV-2 and the disease it causes, COVID-19.

When a Japanese newspaper published a story about Miyazaki having to abandon his research, donations came pouring in. Cat lovers across Japan donated an astounding $2.3 million, prompting Miyazaki to leave his post at the University of Tokyo and found a non-profit dedicated to tackling kidney disease in cats.

As of September 2023, Miyazaki’s organization is running clinical trials on his AIM therapy, and it has partnered with a Japanese pet food company on new food that is supposed to reduce the possibility of kidney disease.

There’s not enough data yet to make any definitive statement, and even if the data existed, the AIM therapy is not a cure: Miyazaki says if all goes well, kittens who are given AIM therapy injections from an early age, and eat a diet with the AIM-enhancing formula, could have their risk of developing kidney problems reduced and potentially live longer lives.

That’s a far cry from Bored Panda’s image of cat lovers dancing in the streets, joyous with news of a miracle pill that will allow Socks and Oreo to run around like kittens for three decades.

While it’s natural to be excited about the potential of AIM therapy, calling it a “miracle” that will “revolutionize feline healthcare” and allow us to grow old with our cats can give people false hope.

Even if the trials go perfectly and AIM therapy breezes through the approval process, the soonest the injection therapy could be available in Japan is 2025. The US, UK and Europe have their own regulatory agencies and clinical data requirements. That means it might help kittens born years from now, but it won’t double the lifespans of the cats we love now.

It’s also worth mentioning that not everyone is thrilled to hear Miyazaki has partnered with a pet food company that sells ultra-processed kibble. Over at bark&whiskers, Karen Shaw Becker — a veterinarian who specializes in preventative care — points out that ultra-processed dry food is thought to be a major contributor to the feline kidney problems, with the ingredients, rendering methods and lack of moisture (water) all posing health hazards to cats. Cats have low thirst drives and get most of their hydration from meat.

While Becker writes she’s watching the trials closely, like other veterinarians, she recommends cat lovers continue to feed their furry friends wet and/or fresh food with high quality ingredients, no fillers and lots of protein.

The People Who Clone Pets Want To Bring Back Extinct Species — And Clone Animals For Their Organs

Genetics, gene-editing and cloning have rapidly matured since the days of Dolly the Sheep, which means we have less time than we think to grapple with some heady moral questions.

Should scientists resurrect long-extinct species? Is it ethical to clone thousands of animals who will not live, but have their organs harvested for human patients?

Those are some of the questions people are asking as the cloning industry — once relegated to producing one-off copies and genetically identical versions of deceased pets for wealthy clients — is expanding with new capabilities.

This story by the BBC’s David Cox provides an informative, brief history of cloning before pivoting to the current state of the industry and how it could continue to evolve.

Two of the most fascinating prospects have to do with conservation. One company, Colossal, is working on bringing back the extinct woolly mammoth, while other scientists are turning to cloning as a way to prevent the extinctions of species like the white rhino, which is functionally extinct without any breeding pairs left living.

Dolly_face_closeup — Scottish scientists shocked the world when they cloned Dolly the Sheep in 1996.

As with anything in science, innovations in cloning unlock new applicative branches, and scientists have partnered with the medical field to address human health concerns. Some, like the practice of editing genes to prevent diseases in newborns, tend to fly under the radar. But others, like the push to adapt organs from animals like pigs so they can be replacements for human organs, are much more controversial and have met opposition from animal welfare groups.

Then there’s the elephant in the room, no pun intended. What about cloning humans?

Right now no one’s gone down that route, at least not publicly, because of the inevitable backlash. What’s happening deep in the bowels of clandestine medical facilities in nations with murky ethics laws is another question entirely.

I am opposed to human cloning, but I don’t believe it will remain the immutable taboo some people think it is. Someone will break the dam, and while that pioneer will likely get raked over the coals, the bell cannot be unrung. Things change so fast these days that what’s shocking one day merits a shrug the next, and it’s possible the world will be introduced to a man or woman one day before it’s revealed the person is, in fact, a clone. (Not unlike the way the world was introduced to Imma, a Japanese influencer and model who exists only digitally.)

Imma has more than 400,000 Instagram followers, she models the latest fashions and she appears in adverts for products like beverages and watches, but she doesn’t exist. She’s a digital creation.

They’ll be the Dolly the Sheep of the human race, and ethicists won’t get a say in whether they should exist because it’s already been done.

“See how normal they are?” people keen on cloning will say. “They’re just regular people. Are you going to tell them they shouldn’t live?”

But before that, it looks like the movie Gattaca will become reality, and people will order up a great baseball player or a child with intuitive musical genius just like they might commission a piece of art or a custom car job. Gene editing with CRISPR is surprisingly trivial.

Of course, it won’t be lost on people that we’re cloning humans when there are millions of unwanted, uncared-for street kids in the third world, not to mention people who live without the consideration of their fellow human beings in every nation. Just like it hasn’t escaped the notice of activists that South Korea and China are leaders in cloning pets, yet dogs and cats are also food in those countries.

What separates the dogs and cats bound for restaurant kitchens from the dogs and cats having their cells preserved for cloning?

Nothing except for their individual value to humans, just like pure luck separates a cat who finds a loving home from a cat who ends up euthanized with a needle. We are a fickle species.

Yet both the beloved pet and the unwanted shelter cat are sentient, experience intense emotions and have their own thoughts. That’s not conjecture, it’s fact as confirmed many times over experimentally, but it shocks a lot of people. Our education system has not done right by the billions of non-human minds we share our planet with.

Cloned monkeys — These rhesus macaque infants were cloned in a lab in China. The remaining barriers to human cloning are ethical, not technological.

I’ve thought about what might have happened if Buddy had been adopted by someone else, and what his fate may have been. I love the little guy, but it’s possible that someone else may have viewed him as an annoyance, a loud and incessantly chatty cat who needs an inordinate amount of attention and affection, sometimes lashes out, and needs to be surrendered.

Likewise, unwanted cats have languished in shelters for months before viral posts spark interest in them, and suddenly offers to adopt come in by the hundreds from across the globe. Nothing about those cats changed, but humans formed an emotional attachment to them after learning their stories.

Of course, the ethics of how we treat and consider animals can change depending on where you’re sitting. If you’re young, healthy and energetic, your view may be radically different than the person sitting on an organ donation waiting list, knowing their time may be up before a new liver or kidney becomes available. Suddenly a seemingly simple moral calculus becomes murky and complex.

There’s strong evidence that people who take the first steps toward cloning their beloved cats and dogs spend time wrestling with the ethics of the decision as well. Texas-based ViaGen, the western leader in commercial cloning, told the BBC that 90 percent of its clients are not people who have gone through with cloning, but have only taken the initial step of preserving their pets’ cells for $1,600.

And what of the mammoths? Bringing them back from extinction isn’t as simple as filling in the gaps in their genome, implanting gene-edited eggs in female elephants and hoping gestation takes care of the rest. Mammoths are social animals. Will an elephant mother raise a mammoth baby? Where does that mammoth baby belong? Without a herd of its own kind, can it be happy?

We can’t ask the mammoths, and even if we could, it might not be up to them anyway. As one paleogeneticist put it to NPR last year: What if the technology isn’t used to resurrect the mammoth, but to save the elephant? Does the end justify the means in the latter situation, but not the former?

What Is Schrödinger’s Cat?

Cats are at the heart of one of the most famous thought experiments in science.

If you’ve spent time around physics types, listened to media appearances by science educators like Michio Kaku and Brian Greene, or even watched episodes of The Big Bang Theory, you’ve almost certainly heard of Schrödinger’s cat.

But what is it, why is it important, and what does it really have to do with cats? Most importantly, if you’re a cat lover, does it involve harming cats?

I promise you, if you stick with me and have a little patience, you’ll not only understand Schrödinger’s cat, but a hugely important element of physics will be demystified for you.

Let’s take a step back. First, we all learned in school that Isaac Newton was the “father of physics,” and Albert Einstein came along about two centuries later, revolutionizing physics by adding to Newton’s work and coming up with his own, more accurate model.

To this day, Newton and Einstein are in a class by themselves among physicists because they single-handedly changed everything we know about the natural world.

We all remember the famous story about Newton watching an apple fall from a tree, wondering why the apple fell down instead of up, and eventually developing his theory of gravity. Newton went on to develop his theories, which describe everything we see in the natural world, from that apple falling to the complexities of orbital mechanics.

Everything seemed to work perfectly, until a physicist named Max Planck came along in 1905 and published a paper introducing quantum physics.

What is quantum physics?

Now the word “quantum” has been incorporated into practically everything these days and has been so utterly abused as a marketing buzzword, a way to add a veneer of science to things that are otherwise nonsense, that it’s essentially a meaningless word to most people. Practically everything is described as quantum, from deodorants to claims of psychic telepathy.

But the gist of it is this: While Newtonian physics does indeed describe everything we see with our own eyes accurately, it does not accurately describe things at the subatomic level.

In other words, there are two sets of rules in our universe. Everything larger than an atom behaves according to one set of rules in our universe, and everything the size of an atom or smaller — which includes subatomic particles — behaves according to a different set of rules.

Not only that, but at the quantum scale, things get really, really weird.

They behave in ways that are completely at odds with everything we intuitively understand about reality, so much so that even Einstein himself was disturbed by what he found. Einstein famously described quantum entanglement — the ability of two different objects to be linked and share properties, regardless of how far apart they are — as “spooky action at a distance.”

So what the hell does this have to do with cats?

Ready to get even weirder?

Thanks to Planck, Einstein, John Stewart Bell and innumerable physicists — who are still studying these concepts, and still winning Nobel prizes for them in 2022 — we know that two particles can be “entangled” and will remain that way no matter how far apart they are.

You could take one particle, transport it 10,000 light years away, and it would still be entangled with the other particle.

But it gets even stranger than that.

Our entangled particles have certain properties, such as their spin, which are unknowable until we measure them. In fact, they exist simultaneously in all possible states until the moment when we observe them, at which time the wave function “collapses.” It’s called quantum superposition.

Not only that, but when we measure one particle in an entangled pair, the second particle’s wave also “collapses” (settles on a certain state) and we know its spin instantaneously, regardless of how far apart the particles are.

If I measure an entangled particle here on Earth and find its spin is up, I know the corresponding particle that’s been moved to, say, Epsilon Eridani, 10.47 light years away, is spin down.

You can see why this would be profoundly disturbing to scientists. It violates the speed of light, and it’s completely counterintuitive. How can the mere act of observation change something in the physical world, and how can it change something else potentially thousands or millions of light years away? Everything we know, every gut instinct we have, screams that this should not be true.

But it is true.

These aren’t just ideas kicked around by scientists smoking the sticky stuff, by the way. They’ve been proven experimentally many times over. No matter how much we might dislike the idea, no matter how weird or spooky it may seem, it’s true.

Enter Erwin Schrödinger, an Austrian physicist. He devised a thought experiment that goes like this:

Imagine you have a sealed box with a cat inside. Inside the box are two buttons: One button feeds the cat a yummy treat, the other button kills the cat. There is an equal (50/50) chance of the cat pressing either button. (Other versions use a more complex system involving radioactive material, or poison, that could kill the cat, again with a 50/50 chance.)

We don’t know if the cat is alive or dead until the moment we open the box. So in this thought experiment, we can think of the cat as both alive and dead until we “measure” or “observe” by opening the box.

That’s what’s happening in the above example of quantum entanglement and the idea that a particle is neither in one position or another until we measure it.

Why is measurement the key here? No one knows. Scientists are still arguing about that. Some believe that there’s some special quality of consciousness that interacts with the universe, so the mere act of observing something can change physical reality.

Others scoff at that idea and insist we’re missing something, that it’s not the act of observation that determines the final state of a particle at all.

Regardless, the important thing here for cat lovers is that Schrödinger’s cat is just a thought experiment.

Schrödinger never had a cat, as far as anyone has been able to ascertain, and no one has used an actual cat in an attempt to reconstruct the thought experiment because 1) You wouldn’t learn anything, since cats are not subatomic particles, and 2) Anyone intelligent enough to be a physicist is presumably intelligent enough to understand how absurd, pointless and cruel it would be to use a living being in an experiment that can’t give you any answers.

For those of us who aren’t geniuses, here’s Sheldon explaining the thought experiment as a child (in Young Sheldon) and as an adult (in The Big Bang Theory):
