Jays demonstrate "flexible tactics" by switching between storing food and stealing from others' stashes, scientists have found.
The woodland birds are known as the shy members of the notoriously intelligent corvid family.

Researchers found that the jays' strategy was dependent on the relative social rank of their opponent.
The results are published in the journal Animal Behaviour.
