Innovative Zoo Training Helps Save Wild Rhino’s Sight

Corralling a wild rhinoceros into a small chute to give it eyedrops might seem like an absurd plan. But if it’s absurd and it works, then it’s worth the risk.

Animal behaviourists partnering with the Palm Beach Zoo & Conservation Society in Florida travelled to Africa in August to help an endangered white rhino with a life-threatening, parasitic eye infection.

Daniel Terblanche, a security manager with Imvelo Safari Lodges, said no one in Zimbabwe would have come up with the plan.

“Believe me, we didn’t think of it; it was a completely ridiculous idea to us,” Terblanche said. “But without trying all of the things that we could to rectify that situation, we would have been in trouble, I think.”

Outside of Zimbabwe’s Hwange National Park, the Community Rhino Conservation Initiative, with support from Imvelo Safari Lodges, engages local communities to reintroduce southern white rhinos to communal lands for the first time in the nation’s history.

Palm Beach 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 jeopardise the future of the program.

Teaching animals to voluntarily participate in their own care

The idea was to coax Thuza into a tight space with his favourite foods and then to desensitise him to humans touching and squirting water on the face.

“Within about a week, we were actually putting the eye drops strategically in his eyes while he held for it,” Lacinak said. “And by the end of two weeks, we had transferred that skill set to not only Daniel, who was in charge of leading their guards, but to the guards.”

The conservation status of southern white rhinos is listed as near threatened, with about 16,000 animals living in the wild. Poaching and habitat loss remain significant sources of danger. So while Thuza and other rhinos continue to face challenges in the wild, at least the animal’s eyes have been protected.

“They’re consistently getting the medications into his eyes every day,” Lacinak said. “And the rhinos are just thriving now and they feel really, really confident that this solved their problem.”
