A study involving over 1200 species of birds revealed that birds with evolved brains are more capable of surviving in harsh environments where they have to hunt for food, shelter and at times even protect themselves from predators.
Conducted by researchers and scientists from the University of Bath in the United Kingdom, the study was published in the scientific journal, Nature Communications.
Findings of the study
• The researchers found that the birds living in highly seasonal environments such as the Polar region have relatively larger brains in comparison to those living near the equator.
• They also found that birds living in areas with unpredictable climate, places that see extreme fluctuation in weather also have larger brains in comparison to their overall body size.
• The researchers further predicted that since the frequency of extreme climatic events like storms, droughts and floods is expected to only increase in the coming years, smarter creatures would be able to adapt better with these changes than the ones with less brains.
• Hence, this result will have significant implications in the future.
According to a researcher from the University of Bath, Tamas Szakely, birds are among the most intelligent species on the planet. He stated that not only do they learn quickly and remember locations but they are also capable of making their own tools and using them.
