Birds have traditionally been thought of as "one trick cultural ponies", exhibiting extensive cultural variation only in song. Indeed vocal learning for bird song is an extremely well-studied example of social learning, and there is abundant evidence that many bird species exhibit geographically variable song cultures. We also now have evidence for culture in birds across multiple behavioural domains.
In this lecture, I detail our current state of knowledge about cultural behaviour in birds. In doing so, I highlight how experiments with birds have played a vital role in improving our understanding of the mechanisms and processes underlying social learning and the emergence of culture.
