Foraging innovations can give wild animals access to human-derived food sources. If these innovations spread, they can enable adaptive flexibility but also lead to human-wildlife conflicts. Examples include crop-raiding elephants and long-tailed macaques that steal items from people to trade them back for food. Behavioural responses by humans might act as a further driver on animal innovation, even potentially leading to an inter-species 'innovation arms-race', yet this is almost entirely unexplored. Here, we report a potential case in wild, urban-living, sulphur-crested cockatoos (Cacatua galerita; henceforth cockatoos), where the socially-learnt behaviour of opening and raiding of household bins by cockatoos is met with increasingly effective and socially-learnt bin-protection measures by human residents.
觅食创新可以使野生动物获得人类食物来源。如果这些创新得以传播，它们可以提高适应性的灵活性，但也会导致人与野生动物的冲突。例如，偷庄稼的大象和长尾猕猴从人类那里偷东西，然后再用这些东西换取食物。人类的行为反应可能是动物创新的进一步驱动因素，甚至可能导致物种间的“创新军备竞赛”，但这几乎完全没有被探索过。在这里，我们报告了一个在野生城市生活的凤头鹦鹉（Cacatua galerita；以下简称鹦鹉）中可能发生的案例，鹦鹉通过社会学习打开和袭击家庭垃圾桶，而人类居民则采取越来越有效的和通过社会学习的垃圾桶保护措施。
