For the first time, a team of international scientists have proven that cockatoos, an iconic Australian bird species, learn from each other a unique skill – lifting garbage bin lids to gather food. The world-first research published today in Science, confirms that cockatoos spread this novel behavior through social learning. Led by Barbara Klump and Lucy Aplin from the Max Planck Institute of Animal Behavior in Konstanz, Germany, along with John Martin (Taronga Conservation Society) and Richard Major (Australian Museum), the team have shown that this behavior by cockatoos is actually learnt, rather than a result of genetics.
Lead co-author, Barbara Klump, said social learning is the basis of different regional cultures, and some animals, such as primates and birds, appear to learn socially. “Children are masters of social learning. From an early age, they copy skills from other children and adults. However, compared to humans, there are few known examples of animals learning from each other,” Klump said. “Demonstrating that food scavenging behavior is not due to genetics is a challenge,” Klump added.
However, a few years ago, Richard Major shared a video with senior author Lucy Aplin, showing a sulphur-crested cockatoo opening a closed garbage bin. The cockatoo used its beak and foot to lift the heavy lid then shuffled along the side to flip it over, accessing a rich reward of leftover food. Aplin, who was then researching at Oxford University and has since moved to the Max Planck Institute of Animal Behavior in Germany, and Klump were fascinated by the footage.
"It was so exciting to observe such an ingenious and innovative way to access a food resource, we knew immediately that we had to systematically study this unique foraging behavior,” Klump said.
