How having a large brain increases a bird’s chance of urban survival
Swedish researchers did a study to test the relationship between brain size of birds and ability to adapt and survive in urban environments. The ability of 82 Species of passerine or perching birds to survive in 12 European cities were studied. The researchers found that the larger brain was in relationship to body sized the better the more likely the bird was able to survive in cities. The one exception was pigeons, which are small brained. Researchers explained that this exception was most likely due to cities being close to pigeons native habitat.
