Crows are quite intelligent birds, it was found by researchers that they have the ability to think and compare the present and past which we people and some other primates have. In The Journal of Neuroscience, it had been published more about these birds and in a study, it had been found that these birds can get the concept of Zero.
Earlier, it was found that these birds can recognize quantities from one another. Researchers from the University of Tübingen in Germany had known that these animals have neurons that fire when they see quantities. In order to know if the crows can identify these quantities, they have conducted a test. They had shown the birds two displayed which had displayed numbers from 0-4. And then birds had been trained to indicate if the numbers displayed on both the displays are the same.
And when they conducted this they have monitored the activity of the bird’s brain. They had found that one new neuron light up when the birds found that the zero is a new number. To IFL Science Andreas Nieder, Co-Author had said that this effect will only be excepted if the birds could get that this zero is the smallest number in the number line.
