A Research Clarifies Why Crowns Are Smarter


It is a fact that most of us know that crows are intelligent animals. But do you know why big-brained birds are more intelligent than crow-like bodies? The reason for this, according to the researchers, is that crows have a long childhood with parents, like humans.

People usually spend most of their lives in their homes, which is a rare situation among animals. However, the crow’s family, which includes ravens and crows, spend a much longer time under the wings of their parents than other animals.

Crows are large and large-brained birds that usually live in social groups. They are known to be smart, use objects around them, recognize human faces, and grasp simple physics. Some researchers even believe that crows can rival monkeys in intelligence.

Crows, like humans, have a long childhood

People continue to train their large brains and develop their cognitive abilities in childhood, under the supervision of their parents. “The intelligence of people is characterized in long childhood, but we cannot be the only one affected by this,” said Natalie Uomini, a researcher at the Max Planck Institute of Human History. says.

Uomini and his team have created a database detailing the life history of thousands of species, including more than 120 crow species of birds, to examine the connection between parental care and the intelligence of birds. Compared to other birds, they found that crows stay more in the nest before breeding, feed their offspring longer, and spend their lives in more families.

Parental care is effective in the development of intelligence

The results published in the Philosophical Transactions of the Royal Society B magazine last week confirmed that crows have unusually large brains compared to many other birds. Birds need to be lightweight to fly more comfortably, but a raven’s brain makes up almost 2% of body mass, similar to humans.

For years Uomini and her colleagues studied the Siberian Jay and the New Caledonian crow, known to be intelligent and had a long childhood. Crows could use sticks to grab food from logs, while jays were able to solve food puzzles and recognize rare predators. Young birds learned these tasks more quickly by watching their parents. Adults were very tolerant and allowed their offspring to practice while learning. Most of the young crows remained with their parents for about twenty years of human age and became more skilled in mental tasks.

Michael Griesser, an evolutionary biologist at the University of Konstanz, argues that experiments help parenting shape larger brains. Large-brained animals such as crows have evolved as both smart and attentive caregivers and have shown that man is not a very unique creature.
