Although the brains of birds are publicly used as an insult, species such as parrots and crows have managed to become famous for their intelligence. So why Don’t all birds have an intelligence close to this species? This question has been answered by a new study. Scientists explained that the intelligence of birds depends on both the number of neurons and the areas of the brain where these neurons are found in large numbers.

In the new study, published in the journal Nature Ecology & Evolution, scientists estimated the number of neurons in the forebrains of 111 bird species. Then these numbers are used by the birds for food or bait. With 4,400 ‘innovative’ ways compared. The result showed that birds with more neurons in the forebrain used more innovative ways.

If there are more neurons in the forebrain, the number of neurons in other parts decreases:

On the other hand, birds with more neurons in the forebrain, where the gray matter is located, are in other parts of the brain. fewer neurons seen. Scientists suggested that the large number of neurons in much of the forebrain also makes the brain bigger. It was shared that all the findings obtained show that the birds’ intelligence depends on the “disproportionate distribution of neurons across cognitive tasks.”

In addition, if the development of individual bird species is compared, slower growing birds More neurons were found in the forebrain. This showed that bird intelligence may require an additional stage of brain development. The fact that species such as crows and parrots, which are known for their intelligence, stayed longer in the nest was also a confirmation of this.
