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

It’s for the best, house cats torture the birds and frogs around here and I hate it. I never knew frogs could scream.

There was a prize-winning photo of a lynx doing that to a rat, a few days ago.

Then further down the page, "A sika deer carries the interlocked severed head of a rival male that had died after their battle". Nature, eh.

Something interesting about the octopus is that it is independent and learning from the time it is tiny. It continually learns from the real world, as more and more neurons accumulate. This layered learning may be an advantage in terms of compact representations. No doubt, the human fetus brain learns much earlier than birth, or even from emergence of first neurons. But it isn't learning from the environment directly…

The zero parenting thing is what gets me. Pretty much every other animal we'd call intelligent leans hard on social learning -- crows, primates, parrots all spend ages learning from adults. Octopuses hatch alone, figure everything out solo in 1-2 years, and then die. That's the wild part. If they had even a 5 year lifespan with overlapping generations, honestly no idea where the ceiling would be. Maybe the octopi in…

Yes, a five year lifespan octopus would be something.

Unfortunately they can't parent, as both parents die directly after reproduction. But octopus can learn from observing, so some kind of mentoring or modeling between individuals could be encouraged or arranged.

And perhaps animatronic or video animations could contribute? If it turned out octopus could learn from video, the potential experiments would be unlimited. Most of an octopus eye's field of vision, maybe all, is monocular.

One of my dreams is to have an octopus reserve and a parrot reserve. And breed and create situational and living contexts for both species, where both individual and social intelligences are brought to the surface and encouraged to flourish.

I view those two animals as the most and 2nd-most (peak, for their separating phylums/classes) alien intelligences on Earth. The octopus intelligence is a true alien from a functional perspective, in that our common ancestor only had a rudimentary nervous system. A bilateral marine worm, 600 mya.

Our common ancestor with parrots would be something like the Hylonomus, 320 mya. something like a primitive gecko.

The differences in managing the two species would be extreme. Water, air. Hermit vs. tight knit social bents. Extremely short generations vs. very long ones.

But both are highly curious and actively engage and bond with people, other creatures and artifacts they find interesting.

Short octopus lives would ironically, be an exceptional boon for breeding longevity. Not only would changes be very apparent quickly, but the short lifecycle makes breeding vast numbers, to implement a broad gene/morph search, relatively inexpensive.

We have 94 parrot genomes [0], and at least one octopus genome. [1] Octopus genes are as trippy as everything else about them.

My guess is with both creatures, a significant intelligence uptick could happen very quickly simply by mining their current very high diversity of genes, across large populations and numbers of sub-species. They are both ideal creatures in that respect.

The west side of Hawaii's Big Island had both an octopus lab and a parrot reserve. The reserve is still there. I was able to visit the lab twice before it was shut down.

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.

How did you arrive at the conclusion that birds like cages?

How did you arrive at the conclusion that they don't?

Not OP but of some bird owners I've see that let their birds hang out in their house / on their shoulders and such the birds willingly go to their cage to rest.

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 relati…

> Animals' intelligence have evolved for survival What do you mean by this? Surely this applies to humans too, we are animals after all. So what distinction did you intend to make?

I mean regarding the domains of intelligence and how to test them.

With humans, performance in one cognitive test correlates with another and so on, generally. So, intelligence across domains.

Researchers test the same with animals. The issue being animals' intelligence being tied to their ecology. The dilemma being what is it worth for an animal solving a task that has no significance in its life. The other argument being if the animals' intelligence is closer/similar to human intelligence, we will find similar results in both.

That's a little different, no? A cage that is open that you can willingly access and leave versus being locked in a cage.

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.

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.
