How New Caledonian crows solve
16 New Caledonian crows make and use tools and tool types vary over geographic landscapes. Social 17 learning may explain the variation in tool design, but it is unknown to what degree social learning 18 accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these 19 crows use to obtain information from others, despite the question’s importance in understand...
متن کاملParallel tool industries in New Caledonian crows.
Individual specialization in the use of foraging tools occurs in hunter-gatherer societies but is absent in non-human primate tool use. 'Parallel tool industries' in hunter-gatherers are mainly based on strict sexual division of labour that is highly reliant on social conformity. Here, we show that 12 individuals in a population of New Caledonian crows on Maré Island had strong preferences for ...
متن کاملEvolutionary Diversification of New Caledonian Araucaria
New Caledonia is a global biodiversity hotspot. Hypotheses for its biotic richness suggest either that the island is a 'museum' for an old Gondwana biota or alternatively it has developed following relatively recent long distance dispersal and in situ radiation. The conifer genus Araucaria (Araucariaceae) comprises 19 species globally with 13 endemic to this island. With a typically Gondwanan d...
متن کاملSocial learning in New Caledonian crows.
New Caledonian (NC) crows are the most sophisticated tool manufacturers other than humans. The diversification and geographical distribution of their three Pandanus tool designs that differ in complexity, as well as the lack of ecological correlates, suggest that cumulative technological change has taken place. To investigate the possibility that high-fidelity social transmission mediated this ...
متن کاملTool bending in New Caledonian crows
'Betty' the New Caledonian crow astonished the world when she 'spontaneously' bent straight pieces of garden wire into hooked foraging tools. Recent field experiments have revealed that tool bending is part of the species' natural behavioural repertoire, providing important context for interpreting Betty's iconic wire-bending feat. More generally, this discovery provides a compelling illustrati...
