Adelaide Zoo’s gentle giant takes part in voluntary x-rays thanks to months of positive reinforcement training
At 21 years old, Adelaide Zoo’s beloved giraffe Kimya is proving you’re never too old to learn something new.
The towering resident recently underwent a specialised dental x-ray as part of her ongoing health care, allowing keepers and veterinary staff to monitor age-related changes to her teeth and jaw – all without the need for sedation.
While dental changes are relatively common in older giraffes, getting detailed imaging of an animal standing more than five metres tall is no easy task. Fortunately, Kimya has been quietly preparing for this moment behind the scenes.
Training built on trust
For months, Adelaide Zoo’s ungulate keeping team has been working closely with Kimya to train the behaviour voluntarily using positive reinforcement techniques.
Team Supervisor of Ungulates, Elise, said the process involved carefully introducing Kimya to every element of the procedure.
“We’ve been working towards getting her comfortable holding still next to an x-ray plate and machine, which is quite a unique behaviour for a giraffe,” Elise said.
“To prepare her, we had to desensitise her to lots of unfamiliar things – the vets, the x-ray equipment and even the protective gowns we wear during the procedure.”
“Surprisingly, the gowns were probably the trickiest part for Kimya to get used to.”
Despite the unusual setup, Kimya has adapted remarkably well and now confidently participates in the sessions.
Clicks, targets and tasty treats
The training relies on a method known as positive reinforcement, where desired behaviours are rewarded with food treats and a consistent sound cue known as a ‘bridge’.
Visitors watching a session may hear a clicking sound as Kimya touches her nose to a target stick presented by keepers.
“That click tells Kimya she’s done exactly the right thing and a reward is coming,” Elise explained.
“It’s a really clear and consistent way for us to communicate with her and shape the behaviours we need for husbandry and medical care.”
The result is a calm and cooperative giraffe who actively chooses to participate in her own health care.
Giving animals choice
Voluntary husbandry behaviours have become an important part of modern zoo care, helping reduce stress for animals while allowing keepers and vets to carry out important procedures safely.
“At Zoos SA, we aim to provide animals with as much choice as possible,” Elise said.
“Kimya always has the option to participate or walk away. We use lots of positive reinforcement to encourage her, but ultimately the choice is hers.”
These behaviours not only support medical care like x-rays, but also provide enrichment and mental stimulation for the animals.
What visitors might see at the giraffe habitat
Guests visiting Adelaide Zoo may spot the giraffe team running a variety of training sessions throughout the day.
From targeting exercises and foot care to specialised medical behaviours like x-rays, each session plays a role in supporting the wellbeing of the herd.
“It’s all very stimulating for the giraffes and every behaviour we work on serves a purpose,” Elise said.
“And for visitors, it’s a great opportunity to see the incredible relationship between keepers and animals firsthand.”
