Parrots are known for their superior cognitive abilities and longevity, with the average Amazon parrot living up to 80 years.

However, this bird, known as the "longest living" bird, lost a leg and became the youngest animal in the world to die.

Parrots are a peculiar species of bird. An Amazon parrot lived in Liverpool, England, where it accompanied its owner to the end of its life until its death at the age of 104.

Even this flightless, dumb and cute-looking owl parrot lived an average of more than 80 years.

Researchers divided the parrots into two groups, one for males and the other for females. By testing and analyzing the two groups of parrots, it was found that both types of parrots have a high level of intelligence, and the older they are the higher their intelligence.

The researchers also found for the first time that the size of a parrot's brain has an effect on its lifespan and that this effect diminishes as the individual's cognitive abilities increase, thus extending the parrot's lifespan.

Although parrots are known for their longevity and cognitive complexity, their lifespan and the proportion of brain size relative to body size are comparable to primates. But whether these two traits affect each other has not previously been clear to scientists.

Fig parrots average 2 years old, scarlet macaws average 30 years old, while other long-lived species have originated from Australian sulfur-crowned cockatoos average 25 years old.

Smelly said: "This type of body type of birds among the average life expectancy of 30 years is extremely rare, some parrots are even longer than humans more than 80 years, even more than human relatable. This type of lifespan is very impressive, bearing in mind that such birds weigh less than one-thousandth of a human being."

Smile said, "It supports the idea that typically the bigger the brain, the more agile the species, the longer the life span, such as when their favorites are eaten up, they can learn to discover new things to survive."

Scientists were surprised to find that diet and other factors or the longer time it takes for the brain to develop do not make the average lifespan longer.

The British journal Nature published an article by Dr. Smelle, a neuroscientist at Massachusetts State University. He points out that this may be due to a lack of adequate understanding of the early stages of brain development. The brain is not static either.

We originally thought that the developmental pathway would play a more important role because, in the case of primates, it is this developmental cost that accounts for the relationship between brain size and lifespan," Smelly said.
