If you're in tune with animals and spend time around a parrot, it's obvious there is a lot going on in their minds. They have incredible memories and their own understanding of their world. It looks simple to us but they are not simple creatures. That being said, I don't know how a bird lover can keep a bird in a cage.

That's kind of how I feel about most pets.

I've thought about getting a pet turtle or tortoise [1] because they are my favorite animal, but I found out that in order for them to be happy and healthy they need a lot more room than I could easily fit in my house. Either a very large aquarium or a very large area for them to walk around depending on the species, neither of which I can easily have in my house.

And I think a lot of animals are like that. Ultimately a lot of these animals evolved in areas that really aren't that "confined" in any meaningful sense, and forcing confines seems kind of cruel.

[1] To be clear, ethically, not one of those shady endangered black market things that you can find.

Many animals (including birds, dogs, horses) like the sanctuary and comfort of a cage and choose to use them, but obviously it shouldn't be used like a prison.

We have a 3-year-old African Grey - he has 3 cages dotted around the house, but he only sleeps in one which is in our bedroom at night, and we never lock him in even if we leave the house.

He knows when we are leaving him when we say goodbye - the garage door opening - the car - the gate opening and closing.

During the day he sits in the home office with me and my office days he is around my daughter.

Most of the time he sits on the top or the side of the cage perching on wooden sticks.

Occasionally he will dismount if the gardening services are busy making a racket with the weed whacker and will walk to the bathroom and climb to the top of the shower.

The one cage is close to an outside gate so he will climb on the window or the gate itself during summer.

We also have 3 cats, but he just walks past them, and he talks and even scolds them in my voice.

I feel similarly about cats. I absolutely love cats but I didn’t have one for five years because I refuse to own one in an apartment. It seems like people torture animals to make sure that they have some attention when they get home
[−] paulryanrogers 46d ago
For those with outdoor cats, please put a bell on their collar. Give the birds a fighting chance.

If you're referring to keeping parrots in cages outside of their natural habitats, that ship sailed when they were brought to non native locations. I'm being hyperbolic, but I assume you don't want them to be released in the wild and die, right?

We have some feral colonies set up in places like Miami and San Francisco, but not all species thrive in warm locations.

That said, my palm sized green cheek conure is rarely in his extremely large cage (it's 4 by 4 feet). Door is always open unless he's sleeping or we're out of the house. Usually he's with me on my shoulder when I'm working during the day and gives his "2 cents" when I'm in meetings.

Most parrots kept as pets prefer it locked for security reasons. He'll get anxious if it's not when he's trying to sleep.

I've seen a lot of terrible bird owners, but I also know plenty that enrich their bird's lives. My little conure has a surprisingly extensive vocabulary for a species not known for speaking.

He says "poo" when when he has to poop, "what's up?" when he greets anyone, "whatcha doing", "", "yeah!" (mimicking Little Jon), "stop" (when he doesn't like what we're doing), "good boy", "Love you" and a few others I can't recall off the top of my head.

> If you're in tune with animals and spend time around a parrot, it's obvious there is a lot going on in their minds.

Not saying there isn't and somewhat offtopic, but if you apply this to LLMs those are much, much 'smarter' than all the animals people like to call intelligent (or something similar). If you disagree, please tell me for which task requiring intelligence you'd rather have an animal's wit than that of an LLM.

I really do feel we should be taking the current state of affairs as a starting point to recalibrate what counts as smart or worth 'protecting', whether it's our beloved animal friends or something inorganic. Simultaneously believing "birds are super smart" and "LLMs are just stochastic parrots" seems absurd.

> I don't know how a bird lover can keep a bird in a cage

I'm convinced that people that keep (uninjured) birds in cages are narcissistic sociopaths. This is based on the conversations that I've had with them about it. Life's too short to deal with people like that. I'm thankful for the indicator to avoid them, but I'm sad that it's at the expense of a bird.

I work on some aspects of intelligence in birds, primarily in songbirds. There have been some effort finding general intelligence ("g" cognitive factor) in birds since last 15-20 years. The results have been mixed as you would expect. Animals' intelligence have evolved for survival and designing experiments to test those are quite hard.

Research has shown brain size matters but not that much, we should look at relative brain size.

[−] junon 46d ago
Parrot owner here. This doesn't surprise me at all. I'm actually a bit surprised they cared about the gyms!

This fits right into the ABC model of parrot psychology:

If you'd like to read a long-form version of this, take a look at Jennifer Ackerman's "The Bird Way" from 2020. Really loved this book.

https://www.jenniferackermanauthor.com/the-bird-way

Also, just my opinion, but Kea's are the best bird there is.

> Dr. Irene Pepperberg studied an African grey parrot named Alex for 30 years. Alex could identify objects, colours, shapes, and numbers. He understood abstract concepts like "same" and "different." His vocabulary exceeded 100 words. When he died in 2007, his last words to Pepperberg were reportedly "You be good. I love you. See you tomorrow." I don't care how you define intelligence -- that one's hard to brush off.

The author takes forgranted the claim of intelligence; and does not assess at all whether the researcher simply said those words to the parrot every night. (Why not? It sounds exactly like what a researcher would tell a parrot before turning off the lights.) A quick search on Wikipedia says the parrot was also found dead in the morning, not in the implied "parrot has last words" scenario.

[−] Sharlin 46d ago
Makes sense, given that to birds, optimizing for weight is everything. But seeing that the ridiculously smart border collies have a comparatively low density of neurons, clearly there’s more to intelligence than that.

Worth nothing that the "mirror test" may not be accurate for a lot of animals - like dogs. Dogs are a lot more sensitive to smell, and can pass smell-based mirror-test-equivalents.

I love watching magpies. I have seen them tease cats by "foraging" just out of sprint and leap distance. They quickly fly up to a tree when the cat moves, always keeping an eye on it, and resume when the cat resets, as other magpies in the group watch from above. I've seen them harass a hawk try to eat a fresh hunt, six magpies surrounding it, taking turns pecking at the hawk's tail until it leaves.

They have interesting interactions with the hooded crows, tolerant of each other but still competitive over food. If a white tailed eagle enters they area they will together team up and attempt to chase it away.

They have complex social interactions with each. I've seen a younger magpie in a group get pinned down by a dominant one while several in the group pecked at its belly, because it ate out of order. They acknowledge even me, their neighbor, who occasionally leaves some winter food out for them.

Anyone who is fortunate to spend real time in or at the edge of nature, and takes the time to observe, should be humbled by the complexity and intelligence of the world around us. Some species stand out, of course, like the magpies.

Most of what we have created as the human race is best characterized as complication rather than complexity, when compared to the utter complexity of the natural world. In the era of AI I find it amusing that we believe we're approaching being able to construct a kind of real intelligence when so many can barely recognize, let alone understand, the "lesser" forms of intelligence around us.

“More neurons = intelligence” always felt like an oversimplification. If that were true, we wouldn’t be surprised by birds or octopuses anymore.

Been to NZ once. Keas are indeed the coolest parrots ever. Climb to the top of Avalanche Peak and you’re guaranteed to see some soaring in the sky, with snowy Mt. Rolleston in the background. Kiwis call them alpine parrots, but they are not. They were common on both islands before Polynesian/Maori hunted many of them, and European ranchers forced them to retreat to high beech forests and alpine zones. Another place is Dart Hut, I even found some kea feathers there.

The Australian sulfur-crested cockatoos are pretty smart. They would teach each other how to open heavy bin lids to raid the garbage. I seem to remember they would even team up to do it. There are studies about how this behaviour spread from suburb to suburb in Sydney.[1]

More recently they've figured out how to operate drinking fountains.[2][3]

One of my all time favourite short stories, with or without intelligent parrots.

Time for me to read it again. This is the Arecibo story, don't miss if you haven't read it before.

"You be good".

Strangely enough, was having a lot of difficulty coaxing google to fetch this link.

Intelligence seems to have evolved on Earth at least three times - mammals, octopuses, and corvids. These are different branches of the evolutionary tree, and the brain architectures are quite different. Octopuses have a distributed system. Corvids get more done with less brain volume and power than mammals.

Before our first trip to New Zealand, March of 2001, we did a lot of research because the plan was to drive up the South Island from the southern tip to the northern, then ferry across to the North Island. We consulted three different Travel books and they all said to be sure to get the rental car insurance and specifically mentioned the Keas.

Sure enough, when we pulled over to a scenic pull over where other cars were, on the way to Milford Sound, there were a couple of Keas attacking a car windshied rubber gasket. I shooed them away, only to see them return. They are really beautiful, mischievous creatures.

Birds are highly optimized. For example, all cells contain a full genome. The genomes in birds are a lot smaller - less trash DNA - which saves them weight and generally makes the cells more efficient.

Makes me think of our current quest with creating AGI, that the metrics for measuring animal brains don't necessarily correlate nicely with "intelligence" or capability.

I imagine an alternate world filled only with intelligent robots that are trying to create "biological-agi" from scratch and are supremely frustrated at the results, throwing neuron count and density at the problem without understanding the fundamental properties that actually create intelligence.

[−] bitwize 46d ago
I think that dogs and cats fail the mirror test not because they are unintelligent or lack a "sense of self", but because their sense of self is tied up with their sense of smell. Mirror reflections don't smell like themselves, so they don't recognize the reflection as themselves. They might recognize the reflection as a strange dog or cat, which may provoke aggression.

> A macaw's brain weighs 20 grams and has roughly the same number of forebrain neurons as a macaque monkey's brain at 70 grams. Ounce for ounce, bird brains are some of the most computationally dense organs in the animal kingdom.

Given parrots can talk, there must be a neuron count that activates language (assuming anatomy allows it), similar to LLM parameter count.

It seems like animals that have to memorize a really wide variety of plants, fruit, flowers, etc tend to have complex and dense brains

Parrots are definitely smart, but birds generally pack a lot into a small mass. That's required for flight.
[−] roywiggins 46d ago
It makes you wonder how smart their ancestors- dinosaurs- were.
[−] api 46d ago
Birds are evolutionarily optimized for low mass.
[−] awinter-py 46d ago
is this a straight-up advantage, or is the trade-off lower connectivity?

> Calling someone a "bird brain" is honestly more of a compliment.

Well no. Some birds are flat-out dumb. Chickens for example.

I have to imagine that given birds are descendants of dinosaurs, which evolved quite a long time ago, they've had a lot more time to optimize certain things.
