Summary: Animal trainer Ken Ramirez has worked with dozens of species living in zoos and the wild. In part 2 of our conversation, Ken describes his years-long effort to use behavioral science to teach a large herd of wild African elephants to avoid a centuries-old migratory route through a conflict zone. It's a hopeful example of the growing role for modern training methods in wildlife conservation and preservation. Plus, Ken has a new book unlike any he's written before.
