New Caledonian crows may understand how to displace water to receive a reward, with the causal understanding level of a 5- to 7-year-old child. Understanding causal relationships between actions is a key feature of human cognition. However, the extent to which non-human animals are capable of understanding causal relationships is not well understood. Scientists used the Aesop's fable riddle -- in which subjects drop stones into water to raise the water level and obtain an out-of reach-reward -- to assess New Caledonian crows' causal understanding of water displacement.
