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.

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.

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.
dofm 1 days ago [-]
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).

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).
lysp 1 days ago [-]
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.

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.

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.

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.

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.
* 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.

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.

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.

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.

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.

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?

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.

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.

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!

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.
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.
fullstop 1 days ago [-]
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. :-)
And this short piece by the same director while looking for the other:
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.

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].
How did the elephants know he died, and how did they know where he lived?
bodash 1 days ago [-]
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

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.

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.

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.

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 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 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.

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.

Everybody speaks in reversospeak when they get heated
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.
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.
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.)

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

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 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.
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).
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.
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.

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.
Ah yes, I am familiar with this Bluey lore
Around here, they come in and try to sell me magazine subscriptions.
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.

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.
It was later repeated, and if given the same training, humans still outperform chimps in this task.
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.
Be thankful. How many people you know are part of a murder?

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.
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.

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

PS. "Hive" five I guess?
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.)

Our dog has started doing the same, from watching the cat.
I like to think the crows from my neighborhood think I'm their cat food god.
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.".
"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.
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.
Anyone know how realistic that concern is?
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:
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
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.
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. :-)
What Ravens Do

And this short piece by the same director while looking for the other:
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.

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

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
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.
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.

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.

So their brain can be equivalent to a much larger primate.
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.
we know nothing of their coordination and base everything on whats equivalent to parameters size
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 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.
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.
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.
They probably felt the same.

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.

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.
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 :)

I saw this video referenced from this guy's longer video about a crow escape room he made: https://www.youtube.com/watch?v=tpg3VvoIVfA
Of course take it with the typical grain of youtube salt
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.
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.
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
“Two things can be true at once” is not an interesting response for this imo.
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.
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

"Society owes you nothing. The woman gave away her labor under a permissive license and the crow society just took what she offered under her own free will. What I really cannot stand is people giving something away and then demanding additional terms."
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.
