If you visit Wegeforth Bowl at the San Diego Zoo to see the animal show, you may be treated to watching a sea lion swim, a lynx pounce, or a serval cat leap. These amazing behaviors performed on cue are the result of the many hours of training put in by our dedicated animal behavior staff. Training is key to the success of our animal shows and presentations. Training is also instrumental in animal care and management. On a stroll through the Zoo, you might notice a keeper asking a lion to rub her side against a fence or asking an ape to present his hand or chest. Training is going on everywhere at the Zoo, with animals from great apes to meerkats. Not only can it make life on exhibit much easier for both the animal and its keeper, it is also enriching. Working with a baby animal allows us the unique opportunity to start training at an early and impressionable age. The behaviors young Boris, our newest reindeer, learns to display in his Zoo environment now will help us manage him as an adult reindeer. (See previous post, Boris Learns Reindeer Games.)
Training animals like Boris to become familiar with things like weighing platforms, crates, loading ramps, trainers, and hoof-trimming tools helps prepare them for routine care and management. To introduce Boris to some of these management practices, we began working on a few training basics. Foot and hoof care is occasionally necessary in adult hoofed animals. We wanted to teach Boris to be calm and quiet when having his feet handled, so we began by gently touching his legs and feet. When he was little, Boris made us laugh with his extreme reaction to any fly that might buzz around his legs. Poor Boris reacted to one single fly as if it were a swarm of 10,000, so we weren’t surprised when his first response to our touch was to stomp and snort, trying to escape our fingers. To him, our hands might as well have been a giant fly coming to get him. Aaack! Thankfully, with practice and gentle repetition, Boris learned to stand quietly and eventually even lifted his feet when his hooves were touched.
Another important part of animal care and health is monitoring body weight. To collect the reindeer’s weights, a large wooden platform was set up on top of a scale in the reindeer’s back area. When the adult reindeer walks onto the platform, the keeper can record each animal’s body weight without causing any stress to the animal. Boris had to learn to step up onto the weigh platform just like the adults. We encouraged him to step up onto the platform by using his bottle as the dangling carrot. On his first try, Boris stepped up onto the platform as if he’d done it a thousand times before. No problem for this little guy!
Some training days that were especially fun for Boris were also a comedic scene for us to witness. One day, when a trailer was available, we backed it up to the reindeer pens and opened the door so that Boris could walk in. He walked up and down the loading ramp and sniffed around exploring the big “new thing.” Boris showed no fear. He quickly made a game of the new thing and trotted up and down the ramp leading into the trailer as if he had claimed it as his new fort. He had conquered his first trailer session with ease.
Boris has proven to be a diligent and eager student. His training will be a continued and significant part of his life in our zoo. Although he still has much to learn, he has done very well with his sessions thus far, and we are very proud of him.

My o’My he is a leggy fellow! too cute!
Boris is growing up so fast right before our eyes! Look at this antlers! They are not the buds we saw before anymore! And the tufts of white hair on his chest too!!! Thank you SDZ for taking such good care of Boris and all other creatures in your possession.
Isn’t it funny the objects you would think would take more effort to work on the behavior, the animals make it the easiest!!! Boris is growing up to be a beautiful reindeer… This was a very interesting post.. I love to read how the keepers works with/train the animals… Thank you!!
Thanks for the info. on our boy Boris who is growing by leaps and bounds. My, what big antlers you have! He’s quite the handsome boy. That was very funny about his reaction to fly’s. It’s obvious you guys love him just from the pictures.
He sure is growing fast! Enjoyed hearing how you work with the animals.
Thank you, Kim, for a delightful blog. All of you who keep us informed about the various animals and goings on do a masterful job…..great descriptions and wonderful humor.
Boris is indeed quite a handsome young fellow and it’s great to hear he is doing so well with his training.
Happy holidays to everyone!
Thank you Kim. I’m enjoying Boris’s training, probably almost as much as he is!! And as Vonna says, he is a very handsome young reindeer.
I have been watching two bears playing in the pool, with the third one walking and pacing near the bank. All this time, I keep wishing that all three would be in the water playing together.
It is SO nice to see the trio together again!
Oh my gosh… How did I miss the video of Boris @ Feeding Time? I just watched it.. I couldn’t find a date on when it was made but Boris’s antlers look pretty much like in the above pictures. Boris going for a walk with the keeper is so cute!! It looks like he is in the exhibit with the other reindeer, but I had to keep the sound down on the video since I’m still at work… If that is the case, does Mom make any acknowledgement of her baby boy?
Moderator’s note: The video was taken last week. He is on exhibit with the other reindeer; his mother acknowledges him as a young reindeer but has made no attempt to care for him.
4pm pst- someone’ is deep sea diving at the stash pipe wall leaving their legs in the air! how long can they stay under and what is in there?
Polar Bear Team responds: The longest recorded time was 72 seconds. Polar bears don’t hunt from underwater, so they haven’t developed the ability to breath-hold like other marine mammals such as seals. But holding their breath for a few minutes does seem likely! FYI: we’ve timed Tatqiq at 71 seconds, and she didn’t come back up gasping, just went back under and kept organizing things in the stash pipe.
MERRY CHRISTMAS AND HAPPY NEW YEAR TO EVERYONE AT SDZ AND WAP!!
