The impression is so strong that it lasts throughout the bird's life. This learning process is called imprinting. It seems that Flopper thinks he belongs with people because of those early experiences, so he'll probably be with people all his life. Imprinting is one of the reasons hand-reared birds are sometimes not suitable for release. Their relatives include magpies, rooks and crows.
Many people consider corvids to be among the most intelligent birds.
We can see that crows and jays are opportunistic and adaptable. Some studies have indicated that crows can even count. Researchers have concluded that blue jays can learn from experiences. A young jay will eat a Monarch butterfly not realizing that it will make him sick. But, after the first experience of vomiting after eating a Monarch, a blue jay will avoid monarchs and their mimics, viceroys, in the future.
