Bigger birds live longer

Birds with large skulls like crows and crows survived better than other little friends. This is because they are better able to regulate behavior and adapt to environmental changes.

After comparing the mortality rate, brain size and body mass of 236 birds in different parts of the world, Sol and his colleagues found that the larger the brain the better they live.

Crows and parrots are the species with the largest brain while pheasants have a relatively small brain compared to the body. Animal studies also yield similar results.

"The problem is that if you have a big brain, you will know how to adjust your behavior and adapt to changing environments better. This will help you survive , " Sol said.
