It has long been known that it is only the more intelligent people who live in cities. Now scientists have discovered that the same is true of birds. It appears that city-dwelling birds have larger brains than their country cousins, the better to deal with the complex threats and opportunities of urban living. The only small brained birds living in cities seem to be ones that have stumbled onto a niche akin to that which would have sustained them in the countryside.

hi there Chris. I think the bigger brained birds live in both city and country, while the smaller brained species stay out in the country. I don't think evolution is a factor, but you never can tell.
