The Western Scrub Jay, Aphelocoma californica, feeds on small animals, such as frogs and lizards, eggs and young of other birds, insects, and (particularly in winter) grains, nuts, and berries.

Like many other corvids Western Scrub Jays exploit ephemeral surpluses by storing food in scattered caches within their territories. They’re also known to steal food from the caches of other birds, for example acorns from Acorn Woodpeckers and pine cones from Clark’s Nutcrackers. Some scrub jays steal acorns they’ve watched other jays hide. When these birds go to hide their own acorns, they check first that no other jays are watching.
