They are capable of emitting many different sounds, but the most common and characteristic way they communicate with their peers , especially when at a distance, is using the caw. Before starting, make sure you know the differences between crows, ravens and rooks.
An animal with as many resources as the crow or the raven can adapt its natural sound according to what it wants to communicate or express. But, why do crows and ravens caw? What signals are sent with a caw? For a few years now there have been numerous ethological experiments with ravens and other corvids that have resulted in conclusions that are surprising to some scientists.
However, if we take into account that crows are capable of solving problems using tools, it makes a lot of sense that their communication methods are also highly complex. It has been demonstrated that the crow has an excellent memory of its peers, recognizing them after periods of up to three years. When a crow meets other corvids, its cawing will differ depending on if the crows are family, a group of young adults or rivals. One of the reasons why crows or ravens caw, then, is to give off a particular signal to those it encounters.
Another reason why crows or ravens caw is to warn their peers of any imminent danger. One of the ways in which a crow perceives danger is when it sees a dead crow. In these circumstances, the frightened crow will emit a row of powerful, even unpleasant caws to raise the alarm. After carrying out a sort of funeral-like sound together, they will flee the area.
Sometimes it takes several days for crows or ravens to return to the site where one of them was found dead, because they assume that the area has become dangerous for them. These behaviors and sounds to notify other members of a group or family and the habit of expressing emotions about the death of a peer are relatively frequent in mammals, but not so much in birds.
As is the case with mammals, crows transmit information to their offspring. The caws of crows are also adapted to signalling "friendly" presences, such as a group of humans that have the habit of leaving food in the same place. They can also serve to guide larger scavengers to corpses and thus get them to open them up so that the crows can take advantage of what the bigger scavengers leave behind. There are caws for specific moments , as the cries of flight, the sounds emitted during a chase or those that are emitted during the courting.
In addition to tone and frequency of cawing, we must also take into account the movements and body language that accompany the sound.
Crows and ravens can make other sounds with their beaks, and they can also use objects to catch their peers' attention. With files from On The Coast.

Thank you for your information. The last few mornings I have heard a murder of crows in trees behind our house. They fly around and it sounds like they are talking to each other, definitely context calls. We have owls and hawks in our neighborhood as well. Just curious as to why all of a sudden they are around, never heard them like this before. Even went around in the afternoon to look to see if there was a dead animal or something, but did not see anything.
Any insight would be greatly appreciated. How long does the behavior last for? Are they perched in a big circle? Are they diving into a particular tree over and over again? These would be good signs of a hawk or owl. It can be surprisingly tough to spot the predator so just keep watching and try to get a view into the branches. Also… pay attention to what the other birds like robins or blue jays are saying. I just moved into a new house about 2 weeks ago.
They bounce from limb to limb in one tree, take flight, do a couple acrobatic swoops and land in the other tree. They caw incessantly both in a tree and in flight. Earlier in the morning I saw some sort of hawk fly in, perch on a limb and eventually leave, but 12 hours later my two crows are still at it.
Are you familiar with this type of behavior? Is it normal or is something happening? Yes this is normal behavior for an alarm situation. This is often what will happen when you have an Owl perching. They can be amazingly well hidden so keep watching. Two days ago my husband got up very early in the morning with tge sound of a group of crows cowing together. Their sound was not ready structured and had no pause and went on for an hour.
My mother who lives in another area in the city also has witnessed the same sound that day. Does it mean anything?
Look for things like: — Where are the crows are located… Are they flying or perched? On the ground? What do they do next? Recently everyday he goes on and on and on like this. Could it be a nest? Thanks for any info. I love crows too. Hi Brian! Your post has been very helpful for me.
When I returned to my apartment after a week long trip I found a crow nest put up on the left hand corner of the grill outside my window. As a result I have a fantastic view of the nest and the two tiny blue eggs. Would they most likely be warning me to back off from the window or ask for more food? If I ever get too close to the right hand side of the window they fly away, and if I wait there for a minute or so, standing still, they eventually return and putter about, all the while facing me so they can keep track of my movements.
This is really interesting. This Spring a crow seems to have befriended me. He usually shows up when I am on my back deck — he?? He also came to investigate what I was doing when I was in my den watching TV — he perched on the eves and was peering at me thought the window!?!
I have a dog — I think perhaps he has been cleaning up some of his leftover kibble on the porch…. Hello, I really hope you can advise me….. A Hynoki Cypress maybe 20 feet tall had blackberries trying to cover it so I did cut the area beneath the tree and about 8feet up — THEN quite surprisingly a pair of beautiful crows that I had been feeding for a year started building their nest — I was able to watch them as the tree is about six feet away from a window.
I did see one young crow that made it out and also saw one of the parents trying to push away the brambles. I asked a wildlife rescue what I should do and they said leave it as is until fall…..
I cannot see the nest so do not know if any birds are still using it. I think their first batch of young are away as the parents do not spend as much time in the area….. Sorry to go on and on but I am heartsick over this…. What is best to do? It has been quaking like and. So I tried to see what was happening. And The Poor wee thing was just sitting there. Like he.. I feel sorry on um.. Hi there, thanks for the video.
Just read a bit of tour bio-sounds like you are doing the work you are meant to do. I seem to have many crows outside my window that have been doing a structured call but it goes on for hours!!! From about am until evening. The fledgling hopped down on its own, and despite my repeated request to my neighbor to not call the animal shelter, she did.
I told her a million times that fledglings seem injured to most people, etc etc. Anyways am I a marked man? Are you noticing this during any particular season? Spring is when courtship happens so there are some unique calls that happen at this time. In my experience, quiet sounds like rattles or clicks tend to be used for short range communication amongst family groups.
I have crows around my house and three of them always seem to caw when I go outside or leave my house with my son.. What does this mean? One or two always seem to follow me down the street as well And start cawing again when I get out of the store..
Just curious if this means something!! In your case, do they make the calls while flying up from the ground? I always encourage folks to connect the sound with behavior before, during and after because it helps you see the context. I would try listening BEFORE you step outside so you can identify whether your behavior is actually the cause of the calls.
This has been a particularly noisy day here in the trees of Barrie Ontario. I often hear them on a Sunday morning and jokingly suggest they are rallying for church. Something is upsetting them to-day. There is more squawking than calling.
I love the stories from your readers and will go back over your information. Thank you. Remember, Crows are just one small part of the bird language universe. Hi Brian, I mimic the song of the birds since I was a child, I am 29 now.
I can understand other birds and make them to answer me with a territorial song. Since I moved to a new country with a lot of crows, I cant make a crow answer to me, I think this is amazing, I have tried to understand the songs that they make to be able to have a conversation with one of them one day, but now I hope to be at least able to call them for food.
The most crows that I cow for just fly away scared of me. Thank you for the videos and information that you are sharing. I am looking forward to learn more. Thanks for sharing Kelly. Have you ever heard of Pavlov and his dogs? He would ring a bell, then give them food and measure their salivation. Eventually he could ring the bell and they would salivate with or without food offered.
Just be very consistent. Give a call whenever you leave your food outside. They should eventually learn to associate food with your call. It might take a bit of time depending on how close you live to their core territory.
Let me know if you try this.
