How old is crow intelligence in human terms?
It is said that crows are very smart and have the intelligence of the lower grades of elementary school, i.e., 6 to 8 years old.
In addition to remembering the damage experiences such as “I was thrown at a stone” and “I was splashed with water,” I sometimes try to get revenge by remembering the faces and clothes of people who harm me.
It is also because of its high intelligence that traps and devices used to drive away crows lose their effect when they know that they are harmless by mere threats.
Furthermore, it is said that the appearance and cry of individuals are discriminated between crows, and information such as dangerous people is shared between parents and children and their peers.
If you attack a crow, you may come to retaliate in groups, so you have to be very careful.
an experiment that shows the intelligence of crows
Here’s an episode that proves how intelligent crows are. This is a well-known experiment on the “Caledonian Glass” found on an island east of Australia.
Water is placed halfway into a long, narrow cylindrical container, and food for crows is floated. However, due to the low water level, the crow’s beak does not reach the bait.
Then the crow drops a stone into the container and raises the water level to the point where the beak reaches. It brought the bait to his beak, and he got the feast beautifully.
It seems that there are some differences depending on the type and individual, but in general, crows are still very smart.
How do you know what food is in a garbage bag
It seems that crows can recognize food in garbage bags not only because of their high intelligence but also because of their excellent eyesight and color discrimination.
Compared to humans, crows have five times more vision and have visual cells that can perceive ultraviolet radiation in addition to red, green, and blue.
To humans, rainbows appear to be seven colors, but to crows, it has also been reported that they may appear to be more than 14 colors.
Therefore, it is said that food can be recognized even in translucent garbage bags where various things are mixed.
