Working with Anna

At the Maryland Zoo in Baltimore, Animal keeper, Katie Ernest works with Anna, a 37 year-old elephant. Ernest uses a "guide" -also known as a "bullhook-" to guide the elephant. The zoo uses them in a humane way as opposed to what the latter name might suggest. The trainers also use body language, voice commands and treats to direct the elephants.
