Observing a new “cultural trend” spreading in real time in the wild - or suburbs - afforded the cockatoo researchers a special opportunity, said Lucy Aplin, a cognitive ecologist at Germany’s Max Planck Institute of Animal Behavior and coauthor of the study. One classic case involves small birds called blue tits that learned to puncture foil lids of milk bottles in the UK starting in the 1920s - a crafty move, although less complex and not as physically demanding as opening trash bins.
