dc.descriptionThe study was funded through a BBSRC David Phillips Fellowship (grants BB/G023913/1 and BB/G023913/2 to CR) and doctoral studentships from the BBSRC (BK), JASSO (SS), and the School of Biology, University of St Andrews (JvdW).en
dc.description.abstractFunctional tool use requires the selection of appropriate raw materials. New Caledonian crows Corvus moneduloides are known for their extraordinary tool-making behaviour, including the crafting of hooked stick tools from branched vegetation. We describe a surprisingly strong between-site difference in the plant materials used by wild crows to manufacture these tools: crows at one study site use branches of the non-native shrub Desmanthus virgatus, whereas only approximately 7 km away, birds apparently ignore this material in favour of the terminal twigs of an as-yet-unidentified tree species. Although it is likely that differences in local plant communities drive this striking pattern, it remains to be determined how and why crows develop such strong site-specific preferences for certain raw materials.
