📰 Why are some birds smarter than others?

If you’ve ever seen a bird stealing your dog’s dry food or a starling in a litter bag, you might think that some birds have learned to take advantage of new feeding opportunities—a clear sign of their intelligence. Scientists have long wondered why some bird species are more creative than others, and whether these abilities come from larger brains (which seems an intuitively likely) or from a larger mind. number (The notion of number in linguistics is addressed in the article “Number …) Neurons in specific regions of brain (The brain is the main organ of the central nervous system of animals. Brain processes…).

It turns out it’s kind of both, according to a recent study by an international team that included members ofMcGill University (McGill University, located in Montreal, Quebec, is one of…) Posted in Ecology and Evolution.

More neurons in the right place may be associated with increased intelligence in birds

The researchers used a new technique to estimate the number of neurons in a specific part of the brain called the pallium in 111 species of birds. Pallium in birds is equivalent to cerebral cortex (the cerebral cortex (or cortex) of cerebral origin, …) man, who, among other things, participates in memory (Generally speaking, memory is the storage of information. It is also for remembering…)I’learning (Learning is the acquisition of knowledge, i.e. the process…)Thinking and problem solving. When these estimates of the number of pallium neurons were combined with information on more than 4,000 food innovations, the team found that the types with the most pallium neurons were also likely to be the most innovative.

“The young of larger species of crows, crows, and parrots, which are known for their intelligence, spend more time in the nest, giving the brain more time to develop and accumulate acrobatic neurons.”
