    I actually had a New Caledonian crow do my taxes for me this year. His beak was a little hard on the keyboard of my computer, but his rates were very reasonable.

    The ability to hold a grudge and shit on the same person's car for years is actually hilarious

    I heard a story about a woman and her young daughter who had a flock of crows in the trees outside their house. Her toddler had dropped her chicken nuggets and the crows came and took them to eat. The little girl loved them and loved to feed them and they set up a feeder and bird bath for them. The mother was a photographer, and she was working a few miles away from home. She was photographing something outside and she had taken the lens cover off and it fell to the ground. Since she was busy getting her pictures she decided to pick it up later after she was done. She forgot about the lens cover completely. When she arrived at her house, the lens cover was sitting on her front porch. The crows had followed her to her work site and had picked up the lens cover when she forgot to. They frequently leave little gifts for them in the bird bath. Little trinkets and shiny pieces of refuse. That story always stuck with me for some reason.
  • Similar to the raven/wolf interaction, it's not uncommon in Greenland to see ravens during caribou season. They will usually circle above you and when you spot them, fly off into the direction of the caribou where they will circle above them. After you shoot the deer, you toss the guts to the ravens as a form of gratitude (and reward). As someone else mentioned, this is functionally a military drone.

    The wolf/raven relationship goes even deeper than described here. Ravens have been witnessed finding suitable prey and signaling to wolf packs by cawing loudly. In other words, the ravens act as spotters for the wolves who then allow the ravens to scavenge part of the resulting kill.

    We once found a dying crow fledgling and brought it in and started giving it medicine. It was something we had done for many other animals including birds before. This little fellow was the first one who didn't resist drinking the medicine and actually cooperated with us in every step of the treatment. To our surprise, it worked and the little fellow got better. Only within a few days we realized that it was capable of a human-like relationship. Sitting with us watching TV for hours while demanding strokes and kisses on his head, getting angry when we turned our back to him (or her), throwing tantrums by picking up stuff and throwing them all around when left unattended and letting us know where he was hiding when he realized we were looking for him (even when we weren't calling him). He eventually got so good at ransoming us by throwing tantrums that we left him in the balcony to stop him from getting bored and one day (nearly 40 days after bringing him in) we only came out to see him gone and tens of crows surrounding our house! It was as if they were asking what was our baby doing in your house? We never saw him again and I still regret leaving him in the balcony although maybe that was the best for him. I've had many many pets and I loved them all. But, this crow was the only one who seemed like a human trapped in the body of a bird. I miss him so much.
  • A young crow once started interacting with us in our garden. It started by fetching things and playing tug of war with sticks. Once we got out a pack of nuts, it did everything to get its beak into it. We started hiding the nuts but that thing would always find the hiding spots. Once I was watching over the nuts and the crow started stealing gloves out of my Rucksack and would drop them at the other end of the Garden. As soon as I retrieved the glove, the crow had free access to the nuts. I just didn't anticipate getting fooled by a crow...

    I believe this wolf crow interaction. I rescued a hatchling blue jay. Taught it to fly, hunt, sing, and survive in the wild. He was free to come and go as he wished, but formed a bond with not only my human family but our dog. This was a dog who would eat most anything small or furry, but he and pidgy used to hang out all the time. One day we had a BBQ and we had a guest who no one in my house liked, a friend of my father's. When he walked onto the property my dog walked up to him, lifted his leg, and urinated on him. At the exact same time Pidgy flew over and pooped on his head. Neither animal had ever done anything like that before and both exited in opposite directions. It was the wildest thing I've ever seen.

    the question everyone should be asking is “why are 7 year olds as smart as crows”
  • I've once seen a crow landing on a sidewalk. The crow then checked the street for incoming cars by looking left and right. The street was clear, so the crow walked on foot to the opposite sidewalk. I remember how impressed I was by that intelligent behavior and at the same time I was asking myself why the crow did not just fly over the street.
  • In one set of experiments I believe conducted in Sweden, one of the test subject crows actually hacked the puzzle box. There was some black box mechanism where inserting trash into one end would cause the machine to dispense food out the other. Well this clever guy managed to jam a stick inside the feeding mechanism, breaking the machine and releasing all the food. They had to remove him from the experiment.

    Crows also pass the test for self aware consciousness. They are aware of their awareness and know what they are.
  • @MB-up3mh
    When I first saw them throwing nuts on the street and then waiting for cars to crack them, I was utterly shocked of how smart they are. Love these guys
  • Amazing presentation. I had a crow who was knocked out of her nest by larger siblings. She had just begun to grow feathers when I found her in my driveway. This was in Van Nuys, California in the early 1990s. I fed her baby bird food, a dry cereal product you mix with hot water to prepare. I used an eyedropper to squirt it into her mouth. She grew up to be a healthy female crow. She would stay with me perched on my shoulder just like parrots do. She was my constant companion for many years. She even learned to say "hello" when I would see her after being out. I named her Jamima. We had many adventures together. We ended up moving to San Diego, to El Cajon, a rather wild desert sort of environ with sage and brush. In the winter Jamima would stay in the garage, sitting up in the rafters. In summer she stayed on an outside tall table with a perch across the top. I had a large cardboard shipping box that I would put over her at night to keep predators away. It was at this location that Jamima finally left me. I came home from a movie late one evening around dusk. She wasn't sitting atop the garage eve where she would usually wait for me to get home. I was baffled, I called her name out for hours that night. I was devastated at her loss. The next morning just after dawn I heard Jamima cawing out in the front of the house. I ran outside and there she was bobbing her head up and down 0n top of a street lamp, obviously excited about something. I put out my arm and called to her to come on down. She just kept chattering and dancing around. After about 5 minutes of this a big black male crow swooped in low over Jamima circled and Jamima lifted up and flew off over the chaparral across the street. My best friend had eloped! About 3 months later I heard Jamima cawing excitedly out front one morning. I ran out and there she was sitting on a low branch of a tree across the street. Again she was literally doing the bop and chattering excitedly. I stood there amazed, calling out "what's up Jamima? You came home!" Finally she lifted up off the branch and flew up about 12 feet above the road. At that point three young crows flew up to meet her from the chaparral. She had brought her babies to show me! I was then so happy for her. I understood my Jamima as she understood me. About four months later my wife brought home a small parrot, a Green-cheeked Conure. I named her Deeter. Deeter passed away, but I still have an African Gray named Peeper, that has lived with me for 29 years now.

    so here's a little story of how I was outsmarted by a gang of juvenile crows when I was about 5-7 years old maybe.. I was a little kid playing at the park and minding my own business when a crow approached me and kept teasing me and then jumping a little backwards.. kept doing that and I tried to get it to leave me alone but it kept coming back.. till I got frustrated with it so I sprinted at it to make it fly away once and for all, but little did I know that it was luring me into a muddied field, and as you can imagine I skid and landed in the mud and was covered in it almost from head to toe. I stood up between the laughs of all the crow gang. YES! they were definitely all laughing at me!! I had a hard time explaining all of this to my mom.. I can only imagine now that she probably was not so impressed with her little kid! lol !! Since then I've always known how smart those beautiful cheeky buggers are!
