The most fascinating fact in this fascinating report on Eastern Black Bear intelligence is:
[Yellow-yellow] now appears to have apprentices; campers have reported seeing other bears getting into their BearVaults.While this speculation is not proven, it's very credible that bears learn from each other. They are very intelligent creatures. Yellow-yellow may not actually need to teach other bears. Upon seeing her succeed, the other bears learn that it's possible to open a bear canister, and that knowledge alone is a powerful goad to keep trying.
Nature is filled with highly adaptive species. We should never think we're the only ones who think.
