Absences electronic interventions in nature

Did quite a lot of YouTube browsing the other day. Found a few fun "nature flicks" the kind we like. I like the part in the Raven's intelligence test video where they say that the ravens "use their frustration" as a motivation for taking intelligent actions leading to success. And also these flicks about that old tortoise called Lonesome George, last known individual of the Geochelone nigra abingdoni subpsecies on the Galapagos.
