Crow successfully completed the cognitive ability experiment
Dr. Simone Pika said these findings gave her fascinating insights into the amazing complexity of the avian brain. Dr. Picka from the University of Osnabrück in Germany published her findings in the “Science Reports” earlier this month, evaluating subjects in experimental tasks to test their understanding of the physical world and how they interact with others Crows interact. Comparing their performance with that of 106 chimpanzees and 32 orangutans who completed similar tasks in previous studies, the researchers found that by four months of age, the cognitive performance of crows was very similar except for spatial memory. .
The fast pace of Crow’s cognitive development is surprising
Dr. Picka told Express.co.uk: “The fast pace of Crow̵
“We had expected performance levels to change in a relatively short time frame of 4-16 months.
“In addition, we do not expect crows to perform the worst in space skill missions because they live in a highly spaced world.
“But here, we suggest that analyzing why species failed in certain tests combined with informed explanations of their ecological and social validity will help to better understand whether different tasks are too easy or too much for a particular species. difficult.
“In addition, socialization may greatly affect cognitive ability, and since we still don’t know much about the cognitive skills and potential of many species, paying attention to the impact of socialization and development is essential for future research.”

Dr. Picka said her research provides more convincing evidence to eliminate the stereotypes that cause the term “bird brain.”
She explained: “For a long time, researchers have indeed underestimated the intelligence, brain structure and cognitive potential of birds.
“This problem can be traced back to the 19th century German neuroscientist Ludwig Edinger (Ludwig Edinger). Edinger believes that the brain of the bird brain is primitive and consists only of the basal ganglia that control instinctive behavior.
“Instead, he believes that the mammalian brain is composed of layers that form the’neocortex’ and control learning.
“In general, the brains of mammals and birds are completely different. Mammals have neocortex, which is the outer layer of the brain, and has a layered (lamellar) organization. It is generally regarded as a high-level mammalian recognition. Knowing sign.

Dr. Simone Pika said that the crow has a personality
“The neocortex is also the largest part of the human brain and is believed to improve the advanced intelligence of primates.
“In contrast, birds do not have a neocortex, but a structure called the cortex, which is organized into spherical clusters of cells (nuclei).”
Dr. Picka pointed out that recent studies have shown that the parrot brain actually has twice as many neurons as the primate brain of the same size.
“During the research process, Dr. Picka particularly liked the crow who worked with her.

She explained: “Crows are wonderful creatures, they have different personalities.
“I have a special connection with our crow Anton. The crow is a very large and beautiful male.
“Even though I didn’t raise them in captivity, I only needed a few weeks before he jumped up to me in the aviary, eating walnuts or snacks, or playing toys with me.
“We also had a vocal communication. The crow made a beautiful voice.”
Like crows, African grey parrots are also very smart
In her surprising conclusion, Crow’s understanding of numbers is more or less.
Dr. Picka added: “They are also sound learners and can imitate words, sounds, noises, etc.”
As for possible future research, she said: “I want to learn more about the fast pace of cognitive development of crows and the cognitive changes that may occur after 16 months of age.
“Our crows show differences between individuals and tasks, so I want to study how their personality adapts to this and how socialization does affect their cognitive development.
Octopus is considered the smartest invertebrate
“Many studies on the cognitive skills of great apes have been conducted on captive individuals in artificial captivity.
“Therefore, compared with the complex ecological and social environment of wild species, their breeding and development experience is completely different, and they are much poorer.
“We still know very little about their cognitive abilities and potential, and socialization and developmental impact are crucial to ensure that the cognitive abilities and potential of species are truly understood and compared.
“Future research should also develop comparative cognitive test batteries, which can be used for real species, not for human cognitive skills.”
