They talk about crows passing knowledge from one generation to the next, and they show an experiment that they performed on some crows.
While the young crows are still in their eggs, the scientists wear masks and capture the adult crows, teaching the adult crows that this mask means danger. What they then find out is whether the adult crows pass the knowledge of the dangerous mask on to their young.
However, in this video the young are learning about the dangerous mask because they get to see the adults react directly to it.
I don’t know anything similar where the adults communicate this kind of thing without the masked person being present.
It is possible that the young ones in turn taught the next generation without the masked individual being present. But I don’t remember and am not going to watch the whole video again right now.
