If humans were to grow up without social structure or education, they would not be very effective at survival. It is due to learning skills through education, etc that makes humans effective.

What we have here is specific populations of corvid species that grew up in relative isolation/protection that enabled them to have social structure to exist between generations.

It should be feasible to influence other corvid populations to show such remarkable feats. As long as there is no big mortality, the younger birds should learn from the older.
