You might be missing the point here, the object of the experiment is not to just feed the birds by helping them with more simple manipulations.

One of my favorite things about your cockatoo videos is how they demonstrate that intelligence and problem solving isn't just about finding the one correct solution, but using what you have to do what's best for you. for cockatoos, that includes just tearing the puzzle apart, because they've got excellent beaks for doing so. It'd be silly not to tear an obstacle apart if that's easier than finding a clever solution. Its wonderful 😊

[@jkixel]

Like others said: I think these birds *can* do multi-stage puzzles, but like you said: each stage needs to be something they learned before. Securing the bar with sticks or dowels, or maybe even rope. Or have them learn with a new puzzle that unscrewing something can lead to a reward (and use a different thread so it only takes like 2 complete turns). THEN integrate that into a multi-stage puzzle. Love these bird videos btw!

Be careful with cotton though as it doesn't decompose in their gut. Sisal & seagrass are the more recommended options, along with things like straw brooms, palm leaf, bamboo etc etc. Cotton's ok if they can't chew it apart though & they do seem to really love the soft texture

I think it fails when you add too many barriers at once and they get frustrated.

But without immediate rewards for a single tadk completion, they don't understand if it was correct or not.

[@tissuepaper9962]

This is exactly what he was talking about when he discussed "sequential trained behavior". They aren't smart enough to get the whole sequence in one go, but if you teach them each step individually then they will remember the solutions they learned and chain them together.

[@axiezimmah]

I think if you use pegs to lock the turning mechanism first, they'll understand that they'll have to remove the lock. Once they figure out that removing the lock is a prerequisite, you can gradually make it more challenging to remove the lock. Screws may be a bit too difficult, especially in combination with locks which they have never seen before.

[@BerryTheBnnuy]

The problem with doing it that way is that it'll teach them that the lock is in the way which defeats the purpose. They're supposed to notice that the lock is blocking the knob and then investigate how to remove the lock. By doing it this way he demonstrates they lack a casual understanding of physical obstruction and multi-step problem solving.

I just wonder what would happen if he started using color and shape to communicate actions more clearly to them, what might happen, you know? I wish we had such a diverse population in my area. We have grackles further in town, which would be interesting to play with. We also have small green parrots. They're usually a bit further into Mexico though.

Popeye might have also learned that the top is a fool's game after watching Chad fail to get into it, so he went for the next most interesting thing. He got to see that nothing interesting happens at the top, so learned pretty quickly that it's not worth the attention.

[@Pixelhurricane]

I think one of the reasons they struggled with the turning knobs is they can't see the mechanism, it goes back to the point you made about object permanence and the knob where if they can't see it they aren't thinking about it. They could turn the knob but it wouldn't be very obvious that doing so helps to remove it from the screw hole since they can't see much effect from just the half turn they'd be able to manage. I'd actually like to see a similar puzzle but instead of unscrewing the locking bolts, have them slot into a clear twist lock on the side so that they can see the effect of turning the knobs. I'd be interested to see if that kind of sequential problem-solving can be done with an easier puzzle to investigate

[@superme63]

Edweena didn't forget about the dial, as such. She just watched you put the seeds in through the top, and figured that that was where the solution was this time, until she went back around and was like "Oh yeah! I gotta spinnamajig it!". And as to them getting stuck with the lock, nuts, and twine, there were just too many new additional steps added at once. If you had of added the lock, then each bolt, then the twine over 4 days, they would have figgured it all out.

[@jeff__w]

“She just watched you put the seeds in through the top, and figured that that was where the solution was this time…” That’s right-under most normal circumstances, the way something goes _in_ is usually the way it comes _out._ Seeing the seeds go in the top was a more powerful immediate stimulus than was the behavior previously learned.

[@laurieleannie]

I wish I could purchase one of these, or knew someone with a 3D printer. I need something like this for my African Grey. He never locked in a cage except at night so he wanders around the house looking for things to “do”. Most bird puzzles with nuts, bolts and washers are his favourite but if he sees you put it together, he figures it out TOO fast. 😂

[@nicofish1000]

Could you try using dowels to hold the knob lock? Maybe put the dowel puzzle next to this one to establish a sequence

[@AmusementLabs]

A hybrid idea; what if you made a channel in the feeder hub that requires they turn it left and then right. Turn it left the seeds fall into a pocket, turn it right they slide down to an opening. Sequential turning.

The other one pulled it back again. That was the end of that game. Many years later I have a Macadamia tree and Black Cockatoos come to visit. Those beaks can crack open a macadamia nut no problem at all. Macadamias give a hammer a run for it’s money. I was lucky to survive my first encounter and still count to 10. Great birds though. It took them a few years to find my tree. Now they come back each year and we share the nuts. Funny watching them eat the seeds out of a lemon though. Great video by the way :)

love these cockatoo challenges. how about combining parts of previous challenges ? Like a mixture of wooden pegs and a spinny thing to get seed

[@KazeKitsune]

I think if you add the bar first, then add one screw, then the other screw, they'll figure it out. It's the layering thing like they do at the free flight zoo thing you mentioned.

[@Maria-chan5863]

Once the screws were removed, the removal of the bar was immediate, so that part obviously works with what they know already. Either using dowels so that it is a series of sequential pulling tasks to free the knob or having a separate test wherein they need to just unscrew something would probably be necessary as an intermediate step, because the only twisting they have experience with is something that only a small amount of turning starts to give rewards.

[@rdmccannic]

Add a peg with a spring return below the rotary output so they have to twist, then pull the peg to get a reward. This would be two separate tasks they've accomplished, but must be done in the correct order every time.

[@Cronin149]

Continuing on with the turning theme, I wonder if they’d be able to solve something that uses essentially an Archimedes screw or a bucket elevator to lift the seeds from the bottom of a container out of the top or side. So far all of your puzzles have involved seeds that are either at the bottom of a container they need to get into or at the top of a container and they need to get the seeds down. I wonder if they’d be able to figure out getting the seeds from the bottom to the top.

[@Operngeist1]

[@mehere8038]

I have a hanging bird feeder for smaller birds that cockies decided to try to land above & pull up with the ropes, which tipped everything off it, so I made them some little bowls on ropes that they could pull up from above & they LOVE them & do them with ease. Takes a little while for them to earn, but one of my smarter ones actually wrapped the rope around something, so that baby could pull it up only half way to get access to make it easier for it to learn & then stood back & encouraged the baby to have a go, while keeping the other cockies away & baby learnt it :) So yes, they CAN pull upwards & enjoy doing so. He could start by just hanging the food in something attached to the top of the railing with a rope & then take it further from there :)

[@Orikon25]

Pretty sure they could figure it out with some small adjustments. Try replacing the side cogs/wheels with sticks that they need to pull out. Pulling things is their first instinct, and the sticks might remind Popeye of earlier puzzles, especially if they're visually identical to the Dow puzzle. Also, I wouldn't be surprised if Popeye was able to figure out the cog by observing Chad or Edweena, like you said. So if you wanna stick with side cogs/wheels, try unlocking the barrier while Popeye is watching you. Then, roll the main cog/wheel to give him seeds, and put the barrier and its cogs back on to see if he'll figure it out.

[@majbach1968]

You could also explain the process of you (Makers Muse) creating increasingly complex challenges for the birds to solve as being "trained behavior."

[@tahunuva4254]

I don't know if somebody had already suggested the idea, but what if you introduce some sort of trigger linkage mechanism?

It would be interesting to see what these birds can identify as a puzzle and how far away you can place a trigger before they no longer see it as a part of a system

[@reonee2801]

I personally think Popeye has enough theory of mind to know that the other birds chasing him away are dumber than them so they just wait until they give up. That’s why they chase of Edweena because Popeye knows that Edweena is smart enough to solve the puzzle so Popeye has to secure the tasty treats by establishing a dominance behavior. And awesome vid btw. I tried feeding the crows nearby for years to test and play with them but they seem less interested or are more frightened of humans so it’s nice to see the nice cooperation between you and the birds. They get snacks and you get someone to play with and awesome content.

[@jaredpoon5869]

One thing you could try is having the same puzzle setup with slightly harder elements set up right next to each other. Maybe the first puzzle is the turning wheel with the second puzzle having two dowels that you take out to release the turning wheel.

honestly, this is a great case study for bird proof trashcan design. If they dont get sequential tasks, seems like thats how locking mechanisms to keep them out of garbage should work

[@shadowgolem9158]

I like your idea of trying pegs on the sides instead of screws.

[@EvelynNdenial]

talking about the training on individual problems and then sequencing them, if you made every puzzle with a consistent design language with each puzzle mechanism having the same color and shape as every other one requiring the same motion. so all dowels would be painted one color, all rotating bits being a triangle shape and the same blue, everything that is not a part of the puzzle being white or clear to make the puzzle more visually simple and easier and not provide any distraction from the actual working parts. if you did that and continued to run different puzzles with these birds you have consistently showing up you probably could increase the complexity over time, since they would learn what to do for each part individually and be able to hit them one at a time like in the example you showed of captive animals.

WOW what an incredibly cool video and a gorgeous pair of birds! I’m really curious if the birds can retain context on multistage puzzles if they can’t see progress. So for example, w.r.t. the 2 pegs puzzle… Puzzle 1 - clear front. Pull out single peg to dispense seeds Puzzle 2 - clear front. Pull out two pegs to dispense seeds Puzzle 3 - clear front from seed hopper to first peg. Opaque below first peg. Pull out 3 pegs to dispense seeds. Thus, the birds must understand that the seeds are still making progress even without seeing them.

my first thought was: it would be a cooperative puzzle -> what if the handle is at the back and needs to be turned by another bird? of course just putting the handle at the back of the box wouldn't do the trick, since one bird coud just walk around after releasing some food - but what if one bird would need to step onto something (maybe a pedal) to release a lid so the 2nd bird could get some nuts or seeds or any other puzzle where two individuals have to work together to get some treats I love this format - thx a lot.

I'm not a professional animal behaviorist by any means, but I have a couple of thoughts/potential explanations for some of the things in the video: 1) When Edweena tries really hard to pry it open even though she should know that it doesn't work, that could be an "Extinction burst". Sometimes an animal has a behavior that's well-rehearsed because it tends to work often; if that behavior doesn't work in a specific situation, the behavior starts going "extinct", but there are "bursts" where the behavior comes back, often even more intensely than before. It's like the animal saying "are we definitely sure this doesn't work anymore? let's really try it to make sure." 2) As far as your question/musing (if you will) toward the end about why some of the birds are so into the puzzles - there's a phenomenon called "Contrafreeloading" where animals do prefer to work for the same reward instead of getting it for free. My personal mental explanation is that maybe it's evolutionarily more beneficial to get the same reward while *also* learning and/or acquiring skills than to just get the reward. So animals evolve to find these kinds of problems intrinsically "interesting". I do think it should be possible to teach a bird to solve a multi-stage puzzle like this. It's just a matter of splitting the stages more, so that they have a chance to see when their actions are actually resulting in "progress" in some way. Like you said, having dowels that pull out instead of twist-off things could be a good start. Especially for the birds who already know that yanking dowels often means progress. It's really cool how they generalize stuff they've learned to new puzzles! Then once they know that taking the things on the sides off is progress, they may be able to figure out the twist-off version. Or maybe start even further back - have the bar there, preventing rotation, but not attached with anything. Here's an interesting experiment that I've never heard of anybody trying: what if you rig it up so that a specific sound is played whenever they are making progress? Can they learn to use the sound as feedback that they are on the right track? Maybe practice first on puzzles they are already familiar with, so they don't have to be learning several things at once, and then increase complexity and see if they are using the sound cues. I love your bird training videos! I really only started watching your channel because of these, then moved on to the neat engineering thingies, and only just recently actually got into 3D printing and started watching the "main" videos.

“I do think it should be possible to teach a bird to solve a multi-stage puzzle like this.” They definitely can. Birds can learn sequences that are 16 or 18 steps long, maybe even more. You train them “backwards,” starting with the last step (e.g., turning the knob), then adding the next-to-last-step, then the one before that, and so on. “Can they learn to use the sound as feedback that they are on the right track?” Of course _but_ it’s a little difficult because the timing of the sound has to be when they are exhibiting the right behavior and not, say, when they've given up or are trying something else. (It’s essentially like encouraging your dog to “keep going!” but a bit more turned to the animals behavior.)

I have one thing to say to Popeye, thank you, thank you for encouraging me to start 3d printing for myself. I cant remember exactly which one, but a video of Popeye encouraged me to buy a 3d printer of my own.I saw a video of you making puzzles with 3d printing quite some time ago, encouraging me to do some research and finding out the usefulness of a 3d printer. Soon, I forgot about Popeye until I saw this video, this video instantly reminded me of the very thing that sparked my creativity, so thank you Popeye, and all the cockatoos that were in this journey.

[@davidspiers6638]

There is a tapestry with a Spanish captain in the 1200s who had a cockatoo as a pet. They're so smart and have individual personalities.

[@xyz7572]

“They’re known for their soothing call.” Cockatoos: *excitedly make the noise of garbage compactor on steroids*

[@Nutririana]

I enjoy a lot this video, i reach your channel trying to learn about 3d printing but this was great

[@VinayVarsani]

Its definitely a lot to do with the sequence of actions and the reward, but if theres a reward between each second action, rather than the third, there's more problem solving skills involed than trained sequential behaviour. E.g. having 1 or 2 seeds fall out when they turn a screw on the side but then they still have to remove another barrier before turning the central wheel

[@ChrisModjeska]

It would also be interesting to see if color-co-ordinating problems helps them figure it out faster. For example having all the knobs be a certain colour, pegs be a different colour, etc.

[@SneakyJoeRu]

Might also be color inconsistency. Did you check if those birds see colors differently? Maybe try color coding the different types of motion.

[@DatMammut76]

I love this channel so much. I LOVE THIS CHANNEL SO MUCH.

[@chriswatson7965]

Edweena was trying to get the top off on her second visit because she saw you put it on. She remembers perfectly well how she did it last time, but figures that there must be an easier way based on what you did.

[@HeavyTF2real]

Idk if you get them in super urban areas, but I’d love to see the problem solving capabilities of Brushtail possums! Our opossums in the US (about as distantly related to Aussie possums as a marsupial can get) aren’t very smart but they’re great at remembering where food is.

[@MakersMuse]

We do have them! They are very shy and nocturnal though. I hear them more than I see them, so it might be difficult testing them heh

[@andynz7]

It's interesting how rotation doesn't seem to be a natural/obvious motion for them to try, they're much more interested in prying and levering which makes sense given their natural environment. It makes you wonder how much of our mechanical intuition is shaped by experience of taps, screws, wheels. It makes our development of simple non-intuitive machines like the screw so much more fascinating!

[@perkeyser2032]

I wish I had space and prowess to build things like this, but I'm just a cripple with parrots, and that will have to do. :) They make my life better. Keep the videos coming. Thanks.

[@taltakaaki6033]

Yeah I think that single rotary motion part of the puzzle is fantastic but it's not something that occurs normally in nature so they can learn it it's incredibly alien to them I do agree with what some others have said and if you replace those screw-in pins on the sides with pull out pins that's much more naturally occurring and something that they'll understand but a little tiny screw inside is just inconceivable

[@unusualfabrication9937]

The birds return! I love this series

[@ElysetheEevee]

It seems with the wild cockatoos, it's ALL about repetition. The captive octopus from Mark Rober's video (which octopi are just different beasts altogether in their complex skills) was wild, but did spend a decent amount of time being enveloped in human things. These wild birds may be around humans a lot in their life, but they aren't AROUND humans a lot. As in, intimately around us. They don't get the benefit of each small exhange and cue that pet birds and other captive birds do to learn from. Humans are very different to each other too, so having this level of variability is just insane to expect them to understand from afar like that. Birds that do all these amazing puzzles do similar enough things to learn from, just as we've seen with Popeye and his associations. It doesn't necessarily have to be the exact same puzzle, but if they're similar enough in their key actions, then a cockatoo that's been exposed to those key actions repetitiously should be able to do them. I've never had a cockatoo (despite wanting one: husband's allergic to birds). We have had cockatiels and such when I was younger, though. I watch A LOT of different sources on bird behavior, have taken animal behavior classes, etc. I'm not COMPLETELY unknowing, but I'd be interested in sicentific study for this. I know there are plenty of bird intellegence studies out there. It's just a matter of finding ones specific to these curiosities. This is just my humble, inexperienced observation. I think the wild cockatoos only have so much processing power and memory for specific actions and whatnot. It seems that repetition, just like for humans, is how to move that experience along to long-term memory. It just seems to take a bit more work for them compared to us, on average.

[@xankersmith9194]

You could try making the side knobs the same color as the main reward knob. They might understand "turn grey knob" -> food , but not turn blue knob.

[@crunchysteve]

In that staged training concept, maybe try a single screw on the front for the locking bar. And staged training is how humans learn complex technical stuff. As a guitarist, I had to start playing C scales, then basic partial string chords (like G over the 4 higher pitched strings and a single finger)... By the time I was 20, I was playing in bands, learning new covers and writing my own tunes. Then a friend bought a cassette portastudio, and in half I decade I was doing audio in the newsroom at the ABC in Hobart. Staged learning works because we learn a simple puzzle, then a slightly harder one, and so on. Going from the knob, to a pair of less evident knobs on the sides was about 3 or 4 stages jump - say, locking bar only, then locking bar with single front screw knob, then2 front screw knobs. Still impressed at cockatoo's ability to learn tools. We're supposed to be a higher species, but these cockatoos prove that learning isn't solely our domain. I love these puzzle videos. Great advocacy for biodiversity, too.

[@emilyrln]

I wonder if you could do a more basic screw puzzle where a screw holds down a lid. If they can associate turning the wheel for seeds with turning the screw with seeds, they may be more likely to engage with the screws on the more complex puzzle. What a fascinating series of experiments!

[@unknown-kj4qp]

I think Edwina forgets about the knob because she tries twisting it with no result at first, which led to her temporarily thinking that the knob doesn’t work.

[@Skippy3rd]

I would've liked to see a version with the screws on the same side as the knob, and maybe even in the same filament colour. I think the object permanence hypothesis is in the way of the barrier removal task. That said, I understand that it would be impractical as an add-on to your existing puzzle, since the polycarbonate front isn't ideal for screws to insert into. Great videos as always!

[@emilyrln]

I wonder if Edweena went for the lid on her second attempt because she saw the seeds go in via that route and figured they might come out the same way. Also love that Chad is a dumb jock 😂 I wonder if Popeye noticed Chad bashing his beak into the poly fruitlessly and realized that he needed a different strategy. If so, very impressive observation!

[@yitspaerl7255]

So sweet to see this!
