Animal behaviorists partnering with the Palm Beach Zoo & Conservation Society in Florida traveled to Africa in August to help an endangered white rhino with a life-threatening, parasitic eye infection. Zoo CEO and President Margo McKnight was visiting the area last year when Imvelo Safari Lodges managing director Mark Butcher told her a health scare with a male rhino named Thuza could jeopardize the future of the program. Thad and Angi Lacinak, founders of Precision Behavior, traveled to Zimbabwe to work up a plan to administer eyedrops to the rhino. They developed a plan based on lessons learned at Palm Beach Zoo, where animals are taught to voluntarily participate in their own care.
