Larger brains have enabled certain species of parrots to live long and healthy lives, as new research suggests.
Parrots are known for their incredible ability to think and their long lives. The latest study conducted by Max Planck researchers has shown that one of these characteristics could be a result of the other. In analyzing 217 parrot species and observing their lifespans, researchers discovered that certain species, Do Birds Have Teeth like the scarlet macaw as well as the sulfur-crested cockatoos have exceptionally long lifespans on average, of as long as 30 years.
These are generally only found among large bird species. They also identified an explanation for these lengthy lifespans in the form of a larger brain size relative to its size. This is the first study to demonstrate a link between brain size and life span in parrots. This suggests that a higher cognitive capacity may help parrots navigate dangers in their environment, and also to live longer lives.
Analyzing comparatives
The next step was to employ the technique of a large-scale comparative study to determine if the renowned cognitive abilities of parrots affected their lifespan. The team looked at two possible theories one of which was that large brains could lead to greater longevity. Also, more intelligent birds
are able to better solve issues when they are in nature, thereby having longer lives. Additionally, larger brains require more time to develop, and consequently need longer lives. For every species, they gathered information on the size of the brain relative to others as well as the body weight average and the development of factors.

Scientists are shocked that factors like eating habits, as well as the longer development time needed to create larger brains, didn’t cause longer average life spans. “We would have expected the developmental path to play a more important role because in primates it is this developmental cost that explains the link between brain size and longevity,” Smeele says. In the near future,
the researchers will investigate whether the role of socialization and culture learning in parrots could be a factor in the long life spans. Smeele says: “Large-brained birds might spend more time with their friends, learning techniques for foraging which have been used for many generations.German Shepherd Chihuahua Mix The longer learning time could be a reason behind the longer lifespans, since it requires longer time to learn, however it additionally, it makes the repertoire of foraging more adaptable.
