City dwelling birds have larger brains relative to their body size, according to scientists.
They have found that family traits are key to identifying why certain birds thrive in European cities.
"Urban adapters" including tits, crows, nuthatches and wrens all come from families of related species that have large brains compared to their bodies.
Scientists suggest that larger brains make birds more adaptable to the changeable conditions of city living.
