The Intelligence of Crows
Nature is full of incredible, sometimes unbelievably exciting things.
American crows (Corvus brachyrhynchos) are amongst some of the most intelligent animals in the world (Baraniuk, 2019).
Crows are very social, living in groups called “murders”. Sometimes these groups can be in the thousands, which must be quite something to experience. Crows are adaptable, playful and often very curious. Crows are also known to be trouble-makers, but I think it makes them resourceful and excellent problem solvers! These beautiful birds knock over garbage bins and scavenge snacks wherever they can, which can make them messy in urban areas, but also allows for their survival in their urban niche (Cornell Lab of Ornithology, n.d).
Humans have known that crows are incredibly sly for a long time, but in recent years research has shown that perhaps they are even smarter than we initially thought (Baraniuk, 2019)!

New Caledonian crows have evolved such that creating and using tools is part of their typical foraging behaviour. This was first seen by researchers at the University of Oxford in 2002 when Betty, a New Caledonian crow, bent a piece of wire to create a hooked tool in order to scoop up some tasty pig heart. At the time, Betty was thought of as an incredibly intelligent crow, but now research has shown that this clever ability is widespread throughout the corvids (Baraniuk, 2019). Though, this is not to negate Betty’s clever abilities!
Since this incredible feat of Betty’s was witnessed by researchers, the nature of these birds’ cognitive abilities has been studied closely.

The video linked above demonstrates a crow nicknamed “007” solving a puzzle with eight distinct steps in order to get a reward of a snack. Though puzzled at first, the smart creature quickly sorts out the steps he needs to take in order to accomplish his task and acquire his treat (BBC Earth, 2014). Watching videos like these, or even watching crows out in nature in urban areas and green spaces, makes me feel a personal connection to them. For me, it leaves me in a state of awe watching birds use their memories, problem solving skills and pure cleverness, to solve a relatively challenging task. I think for me, it makes me feel as though we are so much closer to nature than we feel we are. Crows are brilliant animals, and their playful and mischievous ways make me feel like we have a connection to them that some many not acknowledge. Crows can remember human faces- they remember those that have wronged them and will never forget. Crows are known to swoop down on people that have caused them harm before, along with other members of their murders! They also trust humans that feed them, and will come back to those they trust.
Is there any animal, or any element of nature, that makes you feel more connected to nature? Crows continue to amaze me more each day. What aspects of nature stir up these feelings in you?
A quote from the book, “Gifts of the Crow- How Perception, Emotion, and Thought Allow Smart Birds to Behave Like Humans” by John Marzluff and Tony Angell, that struck a chord in me, when referring to infrared camera imaging of crows to determine what part of their bodies were working the hardest.
“And the crows’ heads were lit up like holiday lights. The energy of thought and coordination illuminated a darkening sky like strings of flying light bulbs.” (Marzluff, Angell, 2013).
