E17. From sparrow songs that go viral across a continent to cockatoos that watch each other to learn how to open bins, Dr. Lucy Aplin, Australian National University / University of Zurich, studies how birds learn from each other and why it matters. Doing it for the culture? Yep. Birds are that impressive!

In this episode you'll hear about:

• How a new white-throated sparrow song spread over 3,000 kilometers in just two decades, replacing a tune that had been stable since the 1950s
• The experiment that proved wild great tits can establish lasting cultural traditions through their social networks
• Why losing a population of birds might also mean losing knowledge that took generations to build
