It was discovered that the original online version of the above article contained errors that were not the fault of the authors. The affiliations of two authors, Fumihiro Kano and Christopher Krupenye, were listed incorrectly on the title page of the article. The Publisher decided to ‘resupply’ (repost and replace) the XML and online PDF of the article. The printed issue has also been correspondingly altered. Elsevier regrets and apologizes for any inconvenience caused by posting (and printing) a new version of this article online, but hopes that the reader will understand the reasons for doing so. © 2021 The Association for the Study of Animal Behaviour
