Woman who rescued injured crow keeps getting 'thank-you gifts' from birds [video]

My late father developed a feeding ritual for a crow that lasted for over a decade and was prompted entirely by the crow’s decision to stand in a particular position, which he would only do if he observed my father in the kitchen. It happened a few times a week on the crow’s own schedule, the same way every time.

There were no gifts but over the years we did witness this crow clearly trying to teach its very dependent growing child how to work the human. Ultimately it never succeeded, and we presume this crow eventually either passed on or moved on. But one of the gaggle of jealous magpies who observed the process did take up the role. Being more timid it didn’t simply stand and wait, but would appear, circle the feeding spot until it got my father’s attention, fly up to one specific branch and wait, but otherwise repeat the process it observed. That went on for a couple of years.

The process itself varied according to what food was thrown out, but the crow slowly developed a particularly clever strategy for carrying off whole stale bread crusts by dragging it to a water bowl, moistening then trimming and diagonally cutting a slot into the bread from one corner almost all the way to the other, such that it could hang either side of the beak in a balanced fashion; the magpie that took over learned this by observation and attempted it from day one.

My mother has a crow (it's lame and very slightly tame). It's the only crow in a huge murder that isn't afraid of her, and the other crows are in absolute awe of it. It's like they don't know how to completely trust a human like it does. The special crow is like a human whisperer.

The fact is, she would feed any of them, but only crow taps on the window, and goes from one window to the next as my mother moves through the kitchen. The others only get the leftovers, but they line up on the fence.

> ... it's lame ... only crow in a huge murder that isn't afraid of her ...

There are a lot of stories about normally human-avoidant animals becoming far less so when their alternatives look grim. I don't think I've ever heard an explanation, beyond simplistic "obvious-logic" ones.

(Yes, crows are smart enough that "obvious-logic" is fairly credible for them.)

Crows are also smart enough to recognise threats to life in others:

This video is so completely insane that if it were not six years old I would assume it was AI.

Genuinely difficult to find any other interpretation of this video than that what appears to be happening is what is happening.

That's interesting. I guess depending on the crow I could also see them figure out that driving critters onto the road creates roadkill meals.

In 2019 an injured siberian tiger came to a russian border post and refused to leave until he was taken to a rehab facility.

My blue jays observe me in my kitchen and fly over and I feed them unsalted peanuts. If there are none around they'll come if I whistle. Cardinals did the same and were less timid and would come closer until I gave them their own feeder now they don't care about me.

Blue jays are so aggressive towards the other birds that come to feed at my kitchen window. We get cardinals, titmouse, chickadee, robins, and others. The blue jays are triple their size and don't care for the competition.

My favourite part about blue jays is that they mimic other birds. So they'll make hawk calls to try and scare the other birds away.

Yeah, the Eurasian jay does this too, though they do it very defensively; they are often shy.

Jackdaws in the UK do it as well, but they definitely hang around like little gangs of urchins on people’s verges and front lawns; humans amuse them.

(They also grieve, despite what people say; I saw our local gang of six once, reduced to five, making odd quiet noises and unwilling to leave one of their gang that had been struck by a car and was quite obviously dead).

Another fun fact about jackdaws is that they love my big sphinx of quartz.

Now excuse me while I pack my box with five dozen liquor jugs.

https://en.wikipedia.org/wiki/Pangram

TIL. We hear and see the blue jays on our property frequently. We occasionally see a hawk but yet we hear hawk calls fairly frequently too. I always assumed I wasn't seeing the hawk. It never occurred to me another bird mimic the hawk calls. That's really interesting.

It's a pity they're such jerks. On their own terms they are absolutely beautiful birds. But they're not so beautiful that I don't also want to see some of the other beautiful birds that live around here.

Blue jays are the only bird that I've seen dive bomb cats. I'd much rather have the cardinals around than the blue jays

The barn swallows we have around here will do that too. Really annoys the cats. I dont know if they kick or grab fur; but the cats will suddenly flinch and look up. Super acrobatic birds, I love watching them.

In the south of England we now have this problem with feral ring-necked parakeets.

Who doesn’t want to see something amazing like a parakeet in a random British back garden? All the other birds, that’s who!

I have 5 blue jays in my yard and they don't care about the sparrows, finches, etc at all. They only feud with the crows.

That's wierd. I have 5 blue jays in my yard and they don't care about the sparrows, finches, etc at all. They only feud with the crows.

I saw some video once about intelligence tests on crows. In one experiment they had a tall but thin glass of water with some treat floating on the surface but it was too low for the crow to reach. So the crow started dropping rocks into the glass, causing the water level to rise, until it could reach the treat.

I was so impressed, I wanted to replicate that. I went to a park around the corner with some nuts to befriend some crows. My plan was to just feed them for a while so they would trust me. But after a few days I had flock of crows following me everywhere through the city. That was a bit too much.

My dad had a friend who worked at a remote logging area and tossed his bread crust to a raven that was perched by the road. Next day, the raven swooped past his truck as he drove past. Eventually he stopped and dug something out of his lunchbox and gave it to him.

Then every day for months, he would just hold a snack in his fingers and the raven would swoop down and grab it as he drove past. Pretty amazing to think about. That level of foresight, adherence to a routine, not giving up (days off, etc).

The Australian Magpie has similar behaviour to crows/ravens, although they are not closely related. They are very intelligent birds and will respond to regular feeding quickly and then expect it. If they are not fed, they'll tap on your window or walk into your house through an open door to tell you off.

They recognise the faces, voices, unique gait, posture and body language of people from their local area, and can remember an average of around 30 people. Some have been known to recognise up to 100 different people. They remember people for around 5 years. They'll know who lives where, what your regular schedule is, and which path you regularly travel along. They even know all the local cats and dogs and even can identify specific bicycles, cars and bright clothing uniforms (such as postal uniform).

During breeding season, they are most famous for swooping anyone near their nest who they deem as a threat (about 10% of males swoop). They will avoid swooping people they recognise though, so friends get a free pass.

They also hold grudges, so if you do something to annoy or threaten them, they will remember you. Some people have been on a magpie's "enemies list", and returned to a location 10+ years later and immediately been targeted, as the bird recognised them. Some birds even teach their young which people are to be treated as enemies.

They are fascinating. I think you understate a little just how aggressive they can be when they are nesting nearby. You literally neeed to run for your life if a local magpie decides you are not to be trusted! Their attacks can be vicious, it makes the news regularly :)

Oh and I saw videos of them opening garbage cans in teams! One cannot possibly do it but they manage it by partnering with their friends.

A while ago they stopped research with backpack-like trackers on magpies because the magpies figured out a way to take the trackers off each other. The first instance of magpie-cooperation that was purely altruistic! No food reward involved.

Down here in Tasmania we have Black Currawongs (strepera fuliginosa) that patrol around on bin night calling out to each other when they find a wheelie bin they can smell food scraps in. An individual bird can open the lids on their own. Our neighbours countered this by zip tying full 600ml water bottles to the lid handles. Heavy enough that a bird couldn't lift the lid, but not heavy enough to stop the lid opening when the truck lifts the bin.

In response to this, the birds now work together in groups of 3 to open the lids. So people started zip tying two water bottles to the bins... the birds can't get past that as there isn't enough room for them to work in a group of 6.

Me, I just put some green waste on the top of my bin before I take it out. We've also replaced our front lawn with native plants and there's lots of things in there that the birds like to eat. When something in there goes to seed we'll often have 20+ currawongs.

They always leave my bins alone.

I couldn't find a link, but there's a Bizzaro strip that shows a sculptor putting the finishing touches on his latest work: an elderly mannequin made of peanut butter and bird seed, dressed and seated in a wheel chair. The artist smiles as he imagines the reaction he'll get when he wheels the sculpture through a park full of pigeons.

Thanks, I appreciate it!

> You literally neeed to run for your life if a local magpie decides you are not to be trusted!

Ah yes, I am familiar with this Bluey lore

If memory serves, it's been shown that they go for the eyes.

Around here, they come in and try to sell me magazine subscriptions.

I knew somebody who had logged in Alaska and they swore that this one town had a huge crow who would hang out by the town's welcome sign and...welcome the visitors. Apparently crows who spend enough time around people will sometimes mimic human speech and this particular crow had been taught to welcome people in.

My family rescued a jackdaw when I was growing up and it lived with us, we named him Klaus.

He could say “goddag” (hello) and “gå væk” (go away), and he would use them in context. Say hello to people entering, and go away if he wanted to be left alone.

When he was young he would steal my granddads cigar, fly up somewhere high in a tree or a lightpole, but where he could be seen, and dismantle it.

He grew very old and had a lot of white feathers in the end. I’ve always liked jackdaws after that, I love seeing them around and their little personalities.

If you like that crow you'll probably get a kick out of Ngarritj the corella: https://www.youtube.com/watch?v=ZbSxc6Y1aVA

Edit: Apologies - dead link, after years of being up :/

See: https://flickerfest.com.au/film/ngarritj/

18 minute short film about a very social corella that adopted an entire community in the north of Australia, surfing on car bonnets, stealing cards from players, performing for food, hurling insults, teasing dogs, etc.

There was an American Crow at a local wildlife rescue who could speak and mimic sounds. He would do a ringtone sort of sound, said "caw, caw" in a very human voice (presumably mimicking people mimicking crows), and sometimes would say "American Crow" (as he was identified by the sign on his enclosure).

I managed to get a recording once: https://drive.google.com/file/d/109wzdIsVW7hZwX1-8M3IioUMr49...

Amazing. In contrast, my dog Chip will drink until he pukes unless I tell him to slow down.

To be fair, many humans do that on a Friday night

Tangentially, ravens sound like humans doing a bad imitation of ravens

Crows are natures version of the flock camera network. I made the mistake of regularly throwing a cup of premium bird seed into the yard. Once they locked onto this activity I got in trouble for stopping. They would do as you describe. I'd see them standing on top of my truck as I walk out of the grocery store.

Only feed them away from your house. These are smart birds, you don’t want them tracking you home ;)

They definitely know where you live

They also know what you did last summer

I had an interaction with a raven in California that made me sure it has seen the Weeping Angels from Doctor Who. I was sitting on the ground, and it was behind me. It clearly wanted a bit of the sandwich I was eating, but it didn't move a muscle. Every time I turned around, it continued to be dead still, but was just a little closer to me. When it was finally about a foot away from me and just as statuesque as ever, I told it to buzz off because I wasn't going to feed it. It seemed to have understood and just walked away slowly, looking back at me occasionally with a hurt look in its eyes.

That’s an Aesop’s fable (the Crow and the Pitcher).

https://read.gov/aesop/012.html

Yes! And it also was an intentional study in animal cognition. Christopher Bird and Nathan Emery at the University of Cambridge decided to test whether birds could actually do what Aesop described. Their study, published in Current Biology in August 2009, was titled: "Rooks Use Stones to Raise the Water Level to Reach a Floating Worm."

https://www.sciencedirect.com/science/article/pii/S096098220...

There was a related study in 2014, "Using the Aesop's Fable Paradigm to Investigate Causal Understanding of Water Displacement by New Caledonian Crows."

https://journals.plos.org/plosone/article?id=10.1371%2Fjourn...

What a fitting name Christopher has

You’ll get a kick out of the concept of nominative determinism, then!

What a fitting name the concept of nominative determinism has.

I once met a woman named Bar. You guessed it, we met at a bar

Another girl I went out with during the same time period was Ifat - and yes, she was heavy set. Moran was actually quite bright, despite her name. Shiran actually did jog, and Hadass did have a nice figure. Tal was shorter than I expected, but Lital was bigger than I expected. Nofit, well, she had great legs at least.

I was friends with a Moran with a BS, MS, and PhD in EE from Stanford.

RIP.

Speaking of animal intelligence: I have always been impressed by the short-term memory of chimpanzees, which outperforms that of humans:

https://www.youtube.com/watch?v=VM5QS_adrIQ

The explanation given by scientists is that chimpanzees need this type of memory to keep a clear mental map of their surroundings while climbing. Still, spectacular.

Unfortunately that was a flawed study. They paired trained chimps with people who saw the task for the first time.

It was later repeated, and if given the same training, humans still outperform chimps in this task.

Any source?

Edit: Answering myself: https://gwern.net/doc/algernon/2009-silberberg.pdf

However,

* we see no videos of the two men doing the test. Notice how the ape barely looks at the task, while the men maybe were highly concentrated.

* The men had the goal to improve and beat the ape, the ape probably did not have that goal.

* The men created the circumstances themself, so it may be possible the knowingly or unknowingly gave themself better conditions than the ape.

* The men did up to 2500 units of training, it is unknown how much the ape got.

* We can see that the ape does nine numbers in some tests, the men did just five.

* the men propably relied on language to learn the task, the ape did not.

So, this is quite a flawed study too.

Indeed. That video made a impact on me too. Obviously people are trying to "debunk" it, but we can clearly see the challenge the chimp was set and how it aces it. Even gaming out scenarios of intense preparation (i.e. cheating) it's hard to imagine most humans matching the performance shown.

> But after a few days I had flock of crows following me everywhere through the city. That was a bit too much.

Be thankful. How many people you know are part of a murder?

This deserves far, far more upvotes than it got ;-)

Around here in the autumn crows engage with various nuts, hard shell ones included difficult or impossible for them to open. So they frequent the bicycle tracks with high traffic, fly above you from the back, elevate a bit while dropping their nuts so you can run those over. Lots of heavy cargo bikes are used by families here, so it is a fruitful exercise for them. Assuming the cyclist realises what is happening and instead of avoiding the nut - like I did the first time not having a clue what this is about - run over it.

Corvids are well known to do it with cars, I believe even intentionally setting nuts (or snails or shellfish) in front of the tires of cars waiting at the red lights. But bikes are probably even better as they don’t completely mush the snacks against the pavement.

My desire to befriend some crows is only increased by this comment.

I have been doing this regularly (unfortunately, can't do it daily) near where I buy groceries, which is next to where my kid goes to school. I started during summer, as a joke - they would have their own Air Force when they returned to school, and now they know my car.

Hooded crows seem to be friendlier, and come the closest, but rooks open their mouths as if I am their parent. They pick up cat food in the air and, sometimes, from my hand (some of the hooded crows do that, and pretty much all the starlings, which we call "honorary crows"). Jackdaws are the least friendly (or the most scared). Sometimes they come in couples, sometimes with their kids.

There are no ravens in my neighborhood, which I find sad. If I ever befriend a couple of them, I'll call them Edgar and Lenore.

haha :D but consider they were not just on some rooftop nearby. They were quite close. I wouldn't mind per se but the social cost... I think it was obvious to everyone in the streets that these birds were following me. I didn't want to be the bird guy.

Your username sounds like something a pidgeon would say...

haha true

So how did you make it stop?

I really tried to befriend some crows but in the end I only got a pigeon ... and in-between I had some really destructive ravens.

Yeah I was already feeling like this year was my crow year, and now I'm understanding how easy it is??

The one that tickled me, was Carrion Crows and Eurasian Magpies using anti-bird spikes as part of their nests, with the Magpies placing them on top possibly to deter other birds.

https://www.audubon.org/magazine/apparently-magpies-and-crow...

> I had flock of crows following me everywhere through the city

That sound so cool, like main character in your story.

Right? Guy has his own Air Force!

Don't piss them off.

https://youtu.be/EQG5fi-2xns

Maybe it had the widely known Aesop's fable in his training set, so this was a skewed evaluation.

Or maybe it broke into the library to find the book that had the answer.

Another member of the birds are not real community in the wild.

Or just an Odin worshiper.

The crow and rocks experiment was a staple “moral story” when I was a child in India. Interesting that someone actually validated it!

This a classic story from Aesop's Fables. https://en.wikipedia.org/wiki/The_Crow_and_the_Pitcher It's been passed down for a few thousand years.

Some crow experts discourage feeding them because they can be a bit too much.

OTOH the Swiss Department of Agriculture says that there is nothing that actually works against corvids. You can scare them and you can make their life difficult, but they learn, and show others how to bypass issues (possibly on "Corvid News"), so they might lose some battle but will win the war.

Oh man. Think about the street creed derived from having a flock of crows following you everywhere. Think about all the possibilities, the things you could train them to do.

Then, after ruling your city, you could start exporting a few crows to neighboring cities, so they could recruit in your behalf.

After your first state, the whole country, then Canada, central america, western europe. Freight liners full of your crows' Army crossing the oceans. Enforcing non-fly zones, eliminating political enemies, spying, policing your domains, directing and supervising human workers.

Command a few AI data centers and a few research labs, put then to work 24/7 on neuralink interfaces for crows, so you could have AI-enabled, starlink connected squadrons of crows.

Then, an accelerated genetic improvement program, CRISPR, cloning, all the stuff. AI-Enabled-Starlink-Connected-Super-Crows. At your command!

Frankly, you should work more on your ambition levels.

One of my favourites as well. Here it is: https://www.youtube.com/watch?v=s2IBayVsbz8

Seems the setup for one of those “the crows have eyes” movies.

https://www.thecrowshaveeyes.com/

I’m quite sure all crows have eyes.

That screenshot from the movie looks terribad and I’m not sure if I want to google it.

My friend saw crows lure a stalking cat into the path of a car, laughed, then ate its road killed carcass.

I saw that video of the experiment with the thin glass as well, it's been years since then but I still tell people about it. Crows are awesome!

We found rick and the two crows

They outsmarted you!

Birds are wild. Found a chickadee fledgling in the road earlier this year and nursed him for a couple days before we found a legitimate rehab. Little guy would just hop out of his box, perch on your finger, and sing as loud as he could until you fed him scrambled eggs. Really got me thinking about how special birds are. We have a hummingbird that visits and he'll do stuff like fly into the garage if the door is open, hover and stare at you for 1-2 seconds, and then take off. It's happened so many times I've stopped being startled by the sudden brrrr noise you hear from their wings flapping (they're so fast they can show up in the blink of an eye).

The bumblebees do something similar (I've oddly nursed three different bees with sugar water—all just happened to be in my field of vision crawling around on the ground but not flying). Now you get a bumble or two per day checking in with a quick hover and bob kind of movement before shooting off into the distance.

Does anyone know of any research into this or books identifying behavior like this?

This is more about beehaiviour research and playing with your balls, but the basic idea seems to be that even "small" brains do the same stuff the big brains do - like forming relationships, playing for fun, using tools, etc.

> the basic idea seems to be that even "small" brains do the same stuff the big brains do

The shorter distances would allow for lower latencies, making the perception of time different. What we take a couple seconds to decide they must think took minutes and we are incredibly slow thinkers. The number of connections is lower, as is the neuron count, and I imagine they can't hold as much in working memory as we do, but, apart from that, they appear to be very smart.

Which is also why I think young children are so annoying to adults. They just think way faster, since they have much less things to consider and past experience to compare with, so they already skipped to the overnext topic, while the adult is still considering the last thing. Also all the people I talked to about it and myself report feeling that time becomes faster is you become older. There is of course also the affect that you perceive time less as you don't pay attention, because it is just regular Tuesday, but even if you only do new stuff for a day, it feels shorter than when you were young.

I agree - time keeps getting faster and faster as I age. In addition to less novelty and change, I like to think of it in terms of the fraction of your life lived so far. When you're 5 years old, every day is about 550 ppm (parts per million) of your life. When you're 35, every day is only 80 ppm. Of course it feels faster!

Portia jumping spiders are incredibly smart. People have done experiments where they place the spiders in a complex environment with food in a hard to access location and they basically just sit there looking around until they've figured out a route to get the food. It takes them a while, I guess because they can only process so much information at a time, but they're remarkably good at doing it.

It's not that simple -- small animals move their bodies much faster than us, but the time scale at which they think seems to be similar to ours.

There was a 2022 study on rats which showed that when they listen to music, they will spontaneously move their bodies to the rhythm, like us. And the range of tempos where this effect is strongest is 120-140bpm.

Heh :)

PS. "Hive" five I guess?

To bee or not to bee - that is the question.

It's all buzzwords.-

This was such a good watch, thank you

Crows are somewhat unique as an animal in that they've got the ability to pass information off to other members of the flock, and to continue passing information down through generations as necessary. The bird saved in this story, if it has offspring, will likely teach them that she is a safe and beloved human. At the very least, there's lots of research into this topic. I can't speak to the others, sorry.

> Crows are somewhat unique as an animal in that they've got the ability to pass information off to other members of the flock, and to continue passing information down through generations as necessary.

Not that unique. My grandfather was a forester, his favourite time passing was to whistle back bird's song, changing only a little bit at a time, turning it slowly into something totally different. The changed song was passed to other birds and offsprings no probs.

The result was quite hilarious, you went to the primeval woods and you could hear wild birds singing the Für Elise... I bet it freaked out ornithologists!

(My granddad died about 30 years ago, sadly the bird "dialect" has vanished since, but I still have some old tapes in the attic.)

Please digitize and post some of these recordings!

Omg please

Restoring avian song culture is an important part of conservation.

https://royalsocietypublishing.org/rstb/article/380/1925/202...

This is an absolutely beautiful story! My mother always whistles back at the birds, but mostly just tries to imitate their songs. But she used to play "Für Elise" on the piano when I was a child :)

Not surprising it died out, and probably quickly. Birds trained to sing Fur Elise would probably be at a disadvantage in attracting a mate imprinted on a more typical song.

Yes! This is a heartwarming story. But the opposite is true. If you happen to piss off a crow, your life will become very difficult. You might as well move towns.

Here in Australia, magpies do something similar but in a bad way. During nesting season they'll swoop you, remember your face, and keep targeting you. My daughter got attacked two weeks ago.

https://www.abc.net.au/news/2022-08-30/magpie-swooping-seaso...

That makes me wonder: If you happened to piss them off, is there a way to appease them again sort of by redeeming yourself and thereby amend the diplomatic relationship?

I feel like there's gotta be

Have a friend, in a mask, kidnap one of the crows. Then you appear, and set it free, and give it cookies. (And your friend stops using the mask.)

This makes the assumption that crows can identify people only by the face. It's quite likely they could recognise something else.

That is not so much an assumption as a conclusion, backed up by research:

https://urban.uw.edu/news/crows-hold-grudges-against-individ...

https://crowlingo.org/journal/marzluff-mask-experiments-expl...

I think the person meant that it might not be for the mask-wearer. They might be targeted by crows even when the mask comes off because the crows might still recognize them from their walking style or body odor or voice etc.

They explicitly are not able to recognize once the mask comes off. That’s the point.

That's why you use your friend!

Or even better: use a (visiting) tourist.

Mostly face - at least crows. There were experiments done with people in mask, and when they remove the mask - crows would no longer recognize them

There was a story a few years back about a woman who did that. She was a target, so she tried leaving treats, and ended up converting one of the crows to her side and it then came to her defense against other birds.

Yeah this happened to me when I was around 12 years old on my way to school. I spotted the crow one day in the middle of the road and thought it was a raven because it was so big for a crow. Then a car came and I guess it thought I attacked it with the car so it got pissed. Since that day it started attacking me every day as I went to school for about 1-2 years. Nothing too serious though but I had to be on my guard, it would literally position itself right where the sun was so I couldn't really see when it would strike at me if it did - most of the time it just screamed at me 5 meters away.

So we need to research if we can apologize to crows.

When our cat was thirsty, he used to go into our shower unit and start knocking bottles of shampoo over until we put the shower head down low and turned it on gently so he could have a drink.

Our dog has started doing the same, from watching the cat.

> will likely teach them that she is a safe and beloved human

I like to think the crows from my neighborhood think I'm their cat food god.

As a child we had a duck that would come nest in our garden for many years, it was really quite friendly, and would come up the patio doors every morning to beg for some food, didn't seem to be afraid of us. She would have her little ducklings follow her around the garden until they eventually went off to some lake not too far away.

Our cats were absolutely terrified of it.

> Our cats were absolutely terrified of it.

I knew a couple that had a pretty big cat, and a parrot (I think an African Grey, but can't remember, exactly).

The parrot would walk around the house, and the cat would ignore it.

I asked if the cat ever attacked the parrot, and the answer was "Yes. Once.".

I guess we know how that went LOL

> Does anyone know of any research into this or books identifying behavior like this?

"Ethology" is the study of the behaviour of non-human animals - https://en.wikipedia.org/wiki/Ethology (see "References" for books).

An old soviet-era book, Science for Everyone: Ethology, What Animals Do and Why? is a great read on this - https://mirtitles.org/2013/10/08/science-for-everyone-etholo... I had read this when i was young and it has always stayed with me. It gives a nice overview of the domain and is highly recommended.

Hummingbirds are weird. I had assumed that given the size of their brains, they'd be not as smart (naive assumption). But they are curious critters! I have a few who visit my backyard, where I have a chair which noone uses. The other day I decided to sit down in the chair and soak in the sun (a rarity in SF, I might add) with my eyes closed. And soon I heard a low buzzing sound, and what do you know? A hummingbird was hovering about a foot away from my face, observing me. It backed off a bit when I opened my eyes, but did hover around for a few more seconds before flying away. The control they have on their flight is unbelievable. They can hover with so much precision!

My ex mother in law bonded with a crow. She had it spending time on her shoulder whenever she was spending time in her garden.

It was quite a sight, especially when she was wearing dark clothing.

A few centuries before people would have had her burned for being a witch.

None of this guarantees she wasn't a witch.

Well, there is a test.

"Very small stones."

One reason I've hesitated to firm this kind of relationship is the fear that, were I to accidentally trigger a violent / startled response from the bird, it could gouge on of my eyes before I could respond.

Anyone know how realistic that concern is?

I've been told imprinted raptors what are otherwise physically fit are not released because of fear of just this sort of thing.

Somehow, I came across this just yesterday:

This short film documents six weeks in the life of a family of ravens in the Verdugo Mountains near Los Angeles. I first noticed two baby ravens who were very small and just out of the nest. This movie covers this family as their parents prepare them to go off and live life on their own.

Nice, Thanks for posting the links.

The documentary in the 1st link is not accessible in my country but at least i now know what to look for.

I fed crows for one summer but had to stop after it kept leaving baby bird parts, usually heads, for me and my neighbors. If it was just me, that's one thing, but my neighbor was tiring of finding bird parts in her bird bath.

I made it to the point where I could jingle my keys to let them know that I was putting food out and they would come down within a few minutes. They love cat kibble and blueberries, but will not eat apples or walnut pieces.

Besides the baby bird parts, I received:

    1. French fries
    2. BBQ ribs, just the bone and a little sauce
    3. Baked ziti noodles
    4. An adult dead bird.  It was opened up, and presumably most of the organs were removed.
    5. Chunks of bread / bun
    6. Chicken nuggets

There's a McDonald's a few miles from my house and I think that they were raiding the dumpster.

It was a neat experience, and I still hear them cawing at me from time to time. You'd think that they would all sound the same, but they definitely have distinct "voices" once you get to know them.

Here is my crow friend: https://i.imgur.com/1A37se8.mp4

> but will not eat apples or walnut pieces

That's so interesting! The crow family I give snacks to loves berries, pecans, and walnuts specifically, but not apples or grapes. Maybe it's a regional thing though, because I'm sure to feed them only things that grow in the area.

Walnuts, apples, and grapes all grow where I live. I was going to suggest that they might go for apples and walnuts if there was no other choice, but they left them there for days. The squirrels would eventually find the walnuts, but nobody (except the ants and hornets) would go for the apples.

If I ever move out of the suburbs into a place more remote / with more land, I'm definitely feeding crows again.

My neighbors used to have a wooden fence, and I was outside and saw a robin with its leg wedged and stuck between the slats. The robin was terrified of me, so I put on some leather gloves and gently dislodged it and released the bird, while it was trying to peck at my fingers. For the rest of the summer, if I was outside, a robin would follow me around the yard and sing to me. I don't know if it was the same bird or not, but I like to think that it was. :-)

in one of the most interesting book "Number: The Language Of Science" by Mr. Tobias Dantzig (yes _that_ Dantzig, father of Mr. George Dantzig, the one who discovered Simplex Algorithm) talks about the "number sense", and has the following (heavily paraphrased) anecdote about a squire who want to shoot a crow that has nested in the watchtower of his estate:

    Whenever he goes into the tower, the crow flies off and won’t come back until he has 
    left. So he tries a trick: two men go in, one comes out, and the other stays hidden. 
    The crow isn’t fooled and waits until the second man leaves too. The same happens with 
    three men and with four. Only with five men, four leaving and one staying, does the 
    crow lose track and return to the nest.

His conclusion is that the crow’s number sense tops out at about four.

IIRC humans have a threshold at the same point. For up to 4 objects we can determine the exact count at a glance. For more we estimate or have to do deliberate counting. Maybe the crow just can't do the deliberate counting.

It is really stories like these remind us to being kind to animals.

When Lawrence Anthony ("The Elephant Whisperer") died of a heart attack, two separate wild elephant herds began walking from different remote areas, covering roughly 12 miles over 12 hours, arriving outside his family home two days after his death, the herds stood near for two full days and nights like a vigil to mourn[1].

[1]: https://www.youtube.com/shorts/9gZceeIxnfo

How did the elephants know he died, and how did they know where he lived?

I think the elephants knew where he lived, so that’s the easy part.

Now regarding how elephants knew he passed (all the sources I’ve seen say no one told the elephants), there are few possibilities:

- whole thing is made up

- someone told the elephants

- the elephants knew through magic/energy/tree of life/etc

- the elephants knew from other animals, maybe the crows told them

Now take your belief

Whenever I see a story about how clever crows are, I'm reminded of that guy who gave the TED talk about crows collecting rubbish after sporting events and picking up coins in return for food. Turned out he made it all up.

Having personally witnessed a group of 5 crows being tricked and driven out of their newly made nest by a pair of bluejays, I have skepticism that they are any smarter than most other birds. Other than owls, which are definitely dumb as a bag of rocks.

Bluejays are in the same family as crows (Corvidae) and are just as smart as crows and exhibit just as strong problem-solving skills. Not sure why crows got all the Corvidae intellectual cred in pop culture.

For example, blue Jays can mimic hawks and use their hawk mimics to clear bird feeders of other species or scare away squirrels after they've watched where they hid their nuts.

Owls don't really have to be smart. They just need to be quick, ferocious, and murderous. Evolution only selects for intelligence when necessary as it's metabolically expensive.

Bluejays are corvid and in my experience they are as smart as crows.

There is also this story of training magpies to recycle bottle caps, which doesn't look fake: https://www.hackster.io/hfor62/training-wild-birds-to-trade-...

This, along with all the evidence we have of other non-human animals’ intelligence, ability to use tools, and at this point undeniable sentience, I find some of the conversation and worrying about anthropomorphizing AI frustrating, and possibly even worrying.

What’s evident is that humans have a long history of anthropo-denial, where we dismiss evidence of non human sentience and intelligence even when it’s starting us in the face.

Those lies have allowed us to engage in what ins fairly obviously unethical mass exploitation of non human animals, which hopefully we will start winding down, but we may also add billions of AIs to that list, if we show the same behavior of denying evidence of sentience in AI this time.

Yes. I think it's clear at this point that all the things a human brain does are emergent properties of a large neural network wired up to a particular set of sensors. Similar emergent properties emerge in any other entity with a sufficiently large "brain", modulo hardware performance and capacity.

I appreciate your AI (Avian Intelligence) contribution to HN.

You may wish to rename that to Swallow Intelligence (SI) otherwise you may be marked as the enemy. The term SI actually reminds me of the super intelligence in Peter F Hamilton Pandora series.

LOL, man, you made my day! Thank you!

Be careful what you wish for. They may start learning to code.

I would gladly teach them.

Makes me think of "Children of Time" by Adrian Tchaikovsky. Great sci-fi series about spiders, crows, and squid evolving and traveling into space. Very different take on space travel. The crows there learn to work as a pair to do advanced tasks.

Not squid, octipodes. Anyway, he does an excellent job of extrapolating from the actual quirks of each animal into a culture and then playing with how those cultures would or wouldn't get along.

His other SciFi is also great.

I'm delighted that I'm not the only person who uses Greek pluralization for a Greek word.

I'm still a nerd, but at least I have company :)

Cheers fellow nerd! I like to pronounce it so that it rhymes with Parmenides, and then imagine that they have a society full of aquatic philosophers (I'm a bit out of step with Tchaikovsky's view on that front).

My late neighbour Tullio (wonderful old man, clock maker) once told me that when he was a kid he cared for a chick crow and they went on to be friends for many years. For example he would ride his bike to work in the morning and the crow would accompany him along the way, and then back home in the evening. What a magical frienship.

There's something beautifully eloquent about how a bundle of feathers may be one of this person's most cherished gifts they ever receive, no amount of money can match that.

On the one hand it’s a sign of crow consciousness. On the other hand it’s a sign of very limited intelligence: obviously crows don’t understand us at all. Just no theory of mind for humans.

It would be like a human thanking a crow by gifting it a DVD player

> obviously crows don’t understand us at all.

What is not obvious. Not at all.

Which is a very high value gift in our culture

Crows reach fabulous levels of (animal) intelligence with a brain that is a fraction of the size of the brain of great apes. I wonder what progress has been made in studying the differences in organisation between the two.

Bird brains are on 2nm process nodes while mammals are 32nm chips

IIRC, short-necked birds have a brain density significantly higher than other birds.

Dinosaur' intelligence compressed into much smaller brain. Maybe lossy but still. Plus they have a good perspective on life and all from above

Silicon or Germanium?

Lol

Well, it has been shown that birds have twice the density of neurons to mammals, and their brain is larger as a proportion of body mass: https://www.pnas.org/doi/10.1073/pnas.1517131113

So their brain can be equivalent to a much larger primate.

I remember having read that bees have a higher neuronal density than birds, and birds more than apes.

Yeah — science is seemingly only just getting into the question of how much of an inner life bumblebees and other solitary bees might have.

There's a lot of surprising things about them, like puzzle solving, some evidence of a capacity for play and the ability to select food not just for nutrition but for apparent enjoyment.

does anybody else at least question the “put a bunch of neurons in a dish” level of understanding behind intelligence

we know nothing of their coordination and base everything on whats equivalent to parameters size

They apparently evolved intelligence separately from mammals: https://www.wired.com/story/intelligence-evolved-at-least-tw...

I once read a theory proposing that primates got their minds from birds due to sharing trees with avians, and that viruses may have transferred genetic material horizontally from birds to primates.

It showed a chart of brain weight relative to body weight, and birds had a much higher ratio than any other animal group. Primates were on the same curve, which wasn't shared with any other mammalian group. Primates were literally on the avian curve.

But I don't remember where I saw that. I searched for it on Google and found nothing.

> Crows reach fabulous levels of (animal) intelligence with a brain that is a fraction of the size of the brain of great apes.

Crows have a higher raw brain-to-body mass ratio (about 2.7% for ravens) compared to adult humans (about 1.9%), so not exactly surprising they are smart.

While interesting, are the brain cells smaller, scaled down with body size? If not, it's not entirely indicative of an increased brain size compared to humans.

my point was their brain is not really a fraction of size when you compare it to their body mass, and anyway bigger brain doesn't really mean smarter animal necessarily, elephants are not that smart, so it's not really about size whether scaled or not

Why is the ratio important? Wouldn’t it be what the brain is capable of doing, determined by “wrinkles”? (Apparently the true indicator of intelligence, at least for humans). I’d imagine the bigger the brain in absolute terms, the more wrinkles, but who knows.

Most of the brain is not doing intelligence, it is doing nerves and muscle control. Larger bodies require larger brains because otherwise they wouldn't be able to control all the muscles needed to move.

It is indeed determined by wrinkles, so listen to your parents, they have more of them. (Sorry, I'm sorry, please forgive)

What an insult to elephants! They won't forget that for a long time.

Related, my favourite section of the book King Solomon's Ring from Konrad Lorenz:

I have already mentioned that jackdaws remember for a long time the creature that once triggered their rattling reaction—that is, anyone who has once attacked a jackdaw. This posed a serious obstacle when it came to ringing the chicks hatched in my colony. If I took them out of the nest to fasten the aluminum Rossitten rings onto their legs, the old jackdaws inevitably noticed and raised an unbridled rattling concert. Well then, what was I to do so that the birds would not fear me forever because of the ringing, since this fear would have immeasurably hindered my work? The solution was exceedingly simple: a disguise! Well, what kind? That was simple too. Lying right at hand in a chest in the attic—and suiting my purposes very well, even though under normal circumstances we only use it on the sixth of December—was a splendid, all-fur Krampus costume, complete with a long-tongued, horned mask that covered the entire head, and a huge, fluffy, stiffly protruding devil's tail hanging from it.

What would you imagine, gentle reader, if on a fine June day you heard a wild rattling coming from a high, peaked roof, and upon looking up, saw the Devil himself—with horns, tail, and hooves, his long tongue hanging out obviously from the heat—climbing from chimney to chimney in the midst of a swarm of deafeningly rattling black birds? I think the overall impression would this time distract your attention from the fact that Satan was using a pair of flat-nose pliers to fasten Rossitten identification rings onto the legs of jackdaw chicks, and then carefully placing the little birds back into their nest. Even I only noticed after finishing the ringing that people had gathered in a dense crowd on the main street of the village, staring at me with the exact same stunned terror as the Whitsun excursionists had from behind the fence back then. Except that had I introduced myself, the whole exercise would have lost its point, which is why I merely gave them a friendly wag of my devil's tail and vanished through the attic window.

I love the local jackdaw crew near me. My lunchtime ritual is to sit down by the water with a pasty, and chuck bits of pastry for them. They're exceptional catches, will pluck it right out the air. Wonderful to watch, really makes my day.

My jackdaws are a lot more cautious. It might be they are scared by the more numerous hooded crows and rooks, but I haven't seen inter-species hostilities, unless between crows and seagulls, which are assholes.

It's a very public spot. The competition is between jackdaws, pigeons, ducks and geese. It's no competition, the jackdaws run rings around the rest.

A woman near me feeds some grey crows. Before I found that out they would "harass" me and my dog when we walked in the area and I didn't understand why.

Then one day I saw the woman walk her 4 dogs and feed these crows. Then I started putting it together, she has smaller dogs, about the same size as mine.

So these crows, presumably, had seen me and my dog about 2km away from where she normally walks her dogs, and came over for food. My dog just thought they were something to chase.

Crows are amazing. I've been feeding a crow in the park for a few years now, and over time we've become friends. I managed to capture him landing on my head (no apologies for the cheesy Top Gun music!):

I used to think chickens were really stupid animals, but since getting mine I've genuinely been amazed at how inteligent and social they are.

My chickens will sit outside the window while I work. They get extremely excited when they see someone who they know will give them treats (they are great at recognising voices and faces). I've even taught my more intelligent one some tricks like to jump up onto my arm when I signal and to fly up onto my shoulders.

In some scenarios they're extremely instinctive, but in others they're very curious and will learn a surprising amount about their environment.

Crows are obviously wayyyy more intelligent than chickens, but it's crazy how smart birds are for such little things. I suspect they have some quite interesting thoughts going on in their little heads.

We have a rental unit on our property that was vacant for a while that had a hole in it somewhere and one summer I was removing about two starlings a day.

What struck me was the varied personality of the birds. Some of them would come right to my hands like it was a Disney movie, others I would have to chase into a corner and carefully capture.

One day I was walking towards my firepit and a whole tree full of starlings was cackling at me getting louder and louder to scold me as I approached and I was pretty offended that they were telling me what to do on my own land. At one moment collectively they flew away in a great big flock with a few slow birds left behind who took off to follow the main bod about three seconds later.

> I was pretty offended that they were telling me what to do on my own land.

They probably felt the same.

Sure but as a human or as-a-fox [1] I am not going to go up in a tree and mess with 200 birds!

[1] like with rare exceptions we can't climb trees!

I've befriended a murder of crows who hang out in the park in front of my flat.

They play with my dog, I can feed some of them from my hand and they follow me around in the neighborhood.

Was really easy, I just kept throwing them shelled peanuts and slowly they got used to me. Cool birds.

In parts of South Asia crows are considered messengers to dead ancestors and are hence fed as part of memorial rituals. This role is probably in no small part due to observations of their intelligence.

'tux1968 shared a great story about helping a crow a few years ago.

Tangentially related, can recommend Crow: From the Life and Songs of the Crow from Ted Hughes. Dark poems, you’ll like. You’ll be able to feel like a crow after reading it.

I worked at Bird Scooters cira 2017-2020 and the internal tool to flash the bird brain was called CROW. Because crows are just that smart I was told.

One of my favourites: https://www.reddit.com/r/greentext/comments/5mi9nu/anon_star... I've always imagined I could do a test just like this.

FYI this can go the other way too.

My wife helped an injured crow out of the road last year, but didn't realize it had already died. The crows knew this. She effectively interrupted a funeral.

For weeks later, the crows would yell at her, and one even dive-bombed and hit her in the head as she got into our car.

Crows are amazing creatures. Make sure you stay on their good side :)

Crows are clever enough to be dangerous (they can remember a face, connect it to a past incident, carry a grudge over that incident, communicate this grudge to their friends, and actively plan violent revenge) but also dumb enough that this intelligence is often self-defeating and counterproductive (randomly attacking people unprovoked). They are a great example of "a little knowledge is a dangerous thing". Thankfully, they are intelligent enough to understand credible deterrence: a surefire way of resolving an ongoing dispute with crows is, of course, by using a gun. Thankfully crow hunting season is quite generous in my state and they taste pretty good.

You’re going to kill an innocent animal just because it’s irritating you? Wtf!?

No, I kill innocent animals because that's my hobby and I enjoy it immensely. I just usually stick to deer because they taste better, are overpopulated in my area, and give a greater meat yield. The seasons are very generous and the tags are very cheap, making it quite economical as a source of protein.

In addition I also shoot nuisance animals, such as groundhogs (which damage fields), rabbits (which eat plants in the garden), and crows (which occasionally get aggressive). This is a very common thing people do in the countryside. The only uncommon thing I do is eat them; most people wouldn't bother with plucking or even breasting out a crow because there's so little meat on it and they have a reputation for not tasting good. But I eat everything I shoot on the principle of it.

My granddad destroyed a crows nest on the family house and they would chase him when he rode his bicycle to work every morning for years…

We're told from kids that Australian Magpies will remember your face for years. Not sure if it's something we just pass it down

Damn, I really dream of having a raven as a pet. They're so smart, about as intelligent as three-year-old kids.

Crows are most definitely intelligent than most of my colleagues.

Its interesting how this woman can go this far for a crow but still eat meat everyday.

Not that interesting, in reality it's more common for shepherds to care for their future meals with kindness and concern than to spend their lives beating a living horse.

This woman and the crow that likes her, for example, both share a common interest in eating meat. To be fair, the crow very probably eats far more babies than the woman does.

Sure, but even so it's pretty interesting in my opinion. The amazing difference in how you treat animals depending on if you see them or not. To feel so much love to a crow that gets stuck and want to help it. Meanwhile, realistically, on the other hand she is contributing to a lot of animal suffering because she likes the way it tastes.

> Meanwhile, realistically, on the other hand she is contributing to a lot of animal suffering because she likes the way it tastes.

You know that?

I know that the animals I eat rarely suffer - I either kill them myself or they're sourced locally from my state, many from farms I've visited.

Not every operation is a poster child for PETA.

The crow in question here has also realistically contributed to a lot of animal suffering. When crows work their way through a nest of infants that cannot escape the last to die live through their siblings being not swiftly killed and see their end coming.

This is unlike how, say, well feed and cared for sheep die - they enter yet another run, like so many others they've passed through in their lives, turn a corner and are instantly stunned out of sight of their peers.

Ergo why I wrote ”realistically”. Realistically most non-vegan people eat factory farmed meat sometime. Any fast food is etc..

we do not keep a crow to the same moral scrutiny as humans because, well, it is a crow.

so I still believe it is interesting!

Animals are not a singular entity. If she was eating crows or croweggs, then you would have an argument.

> or croweggs

You can totally be friends with a chicken, and still eat chicken eggs, they don't mind. Most chickens have been bred to have little interest in incubating the eggs. Not sure how a crow would react...

Side note, I saved a few Guinea Fowl chicks from the road the other day. When I put them down next to the parents and the other chicks, one of the parents launched at me and tried to claw out my eyes. My eyes survived intact, but I had a few scratches on my ears and arms

You can also really like eating meat and still want cattle to be treated well and like animals.

For her, a random crow on the street deserves love and care but not the chickens on her plate she eats every day.

“Two things can be true at once” is not an interesting response for this imo.

> a random crow on the street deserves love and care but not the chickens on her plate she eats every day.

How do you know this?

I know that the chickens I eat run free in large paddocks protected from predators by dogs that go to sleep with chickens running over them.

If you have a specific issue with, say, the US battery hen production system then you should address that.

are you expecting her to eat the live crow?

the chicken is dead and cooked, but also has been raised with certain living standards and ensured to be a certain level of food safety

Rural people in the past could be caught crying while killing their animal they cared for to eat.

You wanna really befriend a bird, give 'em meat. We'd leave bits of dog kibble out for the jays and magpies in our old yard, gone in sixty seconds.

Yeah because animals are dumb creatures and can’t tell good from bad

What do you think the rational value is in discussing animal behaviour using deontological assumptions?

I don't understand the premise of your argument then. I thought you were trying to say the animals are too smart to eat, but then here you are saying they're too dumb. IIRC there have been studies that show plants also "feel" and react to humans, so where are you drawing the line between what is and isn't acceptable to consume by us? What if the human is too dumb to understand that what it is eating has advanced cognition, is it still wrong or do we give them a pass for being too dumb? I don't think you can simplify this matter so easily with a drive-by comment like yours.

Have I missed something, how do we know she eats meat?

Interesting why? Historically, haven't most Canadians preferred to both have pets (or working animals), and eat meat?

How are plant parents supposed to nourish themselves then?

She eats only stupid animals.

Do you want folks in the community to see and discuss it, or do you care about some sort of credit?

I experienced almost the opposite once.

We had a window with a mirrored film to reduce the amount of sun into its room and the neighborhood crows were obsessed with it. They would fly into it, sit right outside the window and chatter loudly, and peck at the window.

Unfortunately this window was on my infant's nursery and the crow noises would constantly wake her up during nap time. My wife asked me to help and I tried a scarecrow, I tried shooing them away right after they woke up the baby, but neither helped. I finally took a pellet gun and shot one of them after another baby-waking incident. All the crows flew away and screeched angrily at me for ~5 minutes before leaving. I never saw them again.

It’s cool how you killed a crow because you didn’t feel like getting a shade and removing the toy that you gave them to play with. They were clearly at fault.

"Fault" has nothing to do with it. A mouse killed in a trap isn't "at fault" for being in my house when I don't want it to be there

Mice spread disease, cause structural damage, ruin food, and can bring mite infestations. This would be more like putting decorative corn cobs on your window sill and surrounding it with traps because you didn’t like the noise squirrels made eating it.

Everybody speaks in reversospeak when they get heated

I, too, tend to make meta commentary when a comment compels me to say something but have absolutely no consequential thoughts to contribute.
