The emergence, spread, and establishment of innovations within cultures can promote adaptive responses to anthropogenic change. We describe a putative case of the development of a cultural adaptation to urban environments: opening of household waste bins by wild sulphur-crested cockatoos. A spatial network analysis of community science reports revealed the geographic spread of bin opening from three suburbs to 44 in Sydney, Australia, by means of social learning. Analysis of 160 direct observations revealed individual styles and site-specific differences. We describe a full pathway from the spread of innovation to emergence of geographic variation, evidencing foraging cultures in parrots and indicating the existence of cultural complexity in parrots. Bin opening is directly linked to human-provided opportunities, highlighting the potential for culture to facilitate behavioral responses to anthropogenic change.

文化中创新的出现、传播和确立可以促进对人为变化的适应性反应。我们描述了一个对城市环境的文化适应发展的推定案例：野生硫冠凤头鹦鹉打开家庭垃圾箱。对社区科学报告的空间网络分析显示，通过社会学习，垃圾箱的地理分布从澳大利亚悉尼的 3 个郊区到 44 个郊区。对 160 次直接观察的分析揭示了个体风格和特定地点的差异。我们描述了从创新传播到地理变异出现的完整途径，证明了鹦鹉的觅食文化，并表明鹦鹉文化复杂性的存在。开箱与人工提供的机会直接相关，
