That’s according to a recent study which looked at why certain birds are able to thrive in European cities. The study found that city dwelling birds have larger brains relative to their body size making them more more adaptable to the changeable conditions of living in the city. Researchers from the Evolutionary Biology Centre, Uppsala, Sweden and the Donana Biological Station, Seville looked at birds such as tits, crows, nuthatches and wrens, studying 82 species of birds from 22 families. The key similarity between them were that they all had a larger brain size relative to body size. I wonder whether the same is true for other animals and perhaps even people.
