    Abstract

    The factors governing the evolution of intelligence are poorly understood. To resolve this issue I investigated the causes and consequences of individual variation in cognitive ability in Australian magpies. I found evidence for a general intelligence factor in Australian magpies, and identified a positive relationship between general intelligence and group size that emerged during development. In turn, there was a positive relationship between general intelligence and reproductive success. Together, these results demonstrate the potentially crucial role sociality plays in the development and evolution of intelligence.
