Crows are quite intelligent birds, and researchers have found that we and other primates can think and compare the present and the past. Much has been published in the Journal of Neuroscience about these birds. And a study has found that these birds can have zero conception.
It has previously been discovered that these birds can distinguish sizes from each other. Researchers at the University of Tübingen in Germany knew that these animals had neurons and would shoot when they saw the size. They are shown by two birds showing numbers from 0-4. The birds are then trained to see if the numbers shown on both shows are the same.
When they did this, they observed the activity of the birds’ brains. When the birds discovered that zero was a new number, they discovered that one new neuron would light up. The co-author told IFL scientist Andreas Nieder that the effect would only change if the birds could get the zero number on the zero number line.
