In one experiment, the jays were given worms (a favorite treat) and nuts. They buried them in separate trays. The researchers learned that if the jays were allowed to return to the trays after a short time, they went straight for the worms. However, if a long time passed, they ignored the worms—knowing the worms would have decayed—and went for the nuts.
One of the most striking examples of corvid intelligence is their sophisticated use of tools. New Caledonian crows, for instance, are famous for crafting hooks from twigs and stripping leaves to create probes for extracting insects from hard-to-reach crevices. Unlike many other animals that use found objects, these crows demonstrate "metatool" use—the ability to use one tool to retrieve another. This indicates a level of causal reasoning and forward planning that was once thought to be unique to humans and great apes.
