Crows are a very intelligent species of bird. many puzzles They can solve it. These birds, known to be quite creative and intelligent, turned heads with a newly discovered feature. Apparently crows can count out loud. For this purpose, crows make and repeat a specific cawing sound.

One of the researchers, a neuroscientist from the University of Tübingen Diana Liao, “Producing a specific set of sounds for a specific purpose requires a complex combination of computational capabilities and volume control.” he said. The researcher states that it is not yet known whether this ability is present in all animals and states that crows can make four different sounds that can be associated with numbers.

Counting out loud is more than understanding numbers

Being able to count out loud is more important than understanding numbers. a much more complex thought process It needs. Because understanding numbers is not enough to perform this operation. At the same time, voice control is needed to send songs. In humans, this process is learned at a very young age.

Although people numbers and math Although crows can learn at more complex levels over time, the fact that crows can understand concepts like zero encourages Liao and his colleagues to believe that crows can understand more advanced numerical concepts.

In the study Learn numbers between 1 and 4 Provided that crows can understand numbers not only when they see the number 4, but also when they see four things together or receive audio signals.
