Cool Facts: There’s a love/hate relationship with humans and Jays because their bold behavior. Most people believe jays are nest robbers, but in a recent study only 1% of jays were found to have eggs or nestlings in their stomachs.

It’s common knowledge that Blue Jays migrate with thousands of them moving past some points along the Eastern coast, however not all Jays migrate and which do and don’t is a mystery to ornithologists. Younger jays are more likely to migrate and while most adults do, some don’t. Some skip migration one year then migrate the next.

Blue Jays are known to mimic the calls of hawks. It is believed that these calls provide information to other jays that a hawk is around, or that they are used to deceive other species into believing a hawk is present.

It is said the tool use is a sign of superior intelligence and while tool use in birds is rare, captive jays are known to have use them. They will take used strips of newspaper to rake in food fallen from outside of their cages. Besides jays, parrots, ravens and crows are known for tool use.
