Getting submerged in new training

Our hippos, Boipelo and Adhama, love to show off their skills during keeper chats!

Dallas Zoo Hippo Keepers Christina E. and Christine S. guest blog on ZooHoo!

We train almost every animal that calls the Zoo home. Training lets animals participate in their own care and enables staff to provide excellent animal husbandry. It can be something as simple as teaching the animal to shift from one space to another. Or as complex as training the animal to allow ultrasounds. Animals, like the hippos, can be asked to present certain body parts to keepers to facilitate routine checkups, or to open their mouths for teeth examinations and x-rays. To do this we use operant conditioning, focusing on positive reinforcement techniques. This means if the animal does the behavior we ask, they are rewarded. A reinforcement or reward can be anything the animal enjoys. Food is the most common reinforcer, but some animals prefer attention, tactile reinforcement, or their favorite enrichment item.

At the Simmons Hippo Outpost, our hippos LOVE to show off trained behaviors that they have learned over the last year. During our keeper interactions, you may have seen Adhama and Boipelo opening their mouths to present their teeth, swimming across the pool, or targeting. Targeting is one of the first behaviors most animals learn because it is a good starting tool that leads to more complex behaviors. Adhama and Boipelo are asked to touch their noses to the end of the target. Their target stick is a long bamboo pole with a buoy on the end that’s lightweight and floats, making it ideal for our hippos. This behavior is typically easy to teach.  Most animals are curious by nature, so when the target is first presented they want to examine it and come closer. After they take that first step towards it, they’re rewarded. They continue to be rewarded the closer they get until finally touching the target. Once the animal learns that touching this target gets them a reward, it becomes one of their favorite behaviors.

Keeper Christine S. works with Boipelo on target training.

We recently started training some behaviors at our underwater viewing area, which brings Adhama and Boipelo so close that you just might think you’re in the water with them.  Boipelo is a pro at targeting underwater, while Adhama prefers to stay above the surface at the moment. Boipelo tends to be shyer in front of crowds and lets her boyfriend shine. Adhama definitely likes to monopolize the spotlight and will do some targeting, opening his mouth, and moving back and forth across the window.

 

In Greek, Hippopotamus means “river horse,” and they do look like graceful horses trotting in slow motion underwater. However, don’t let this fool you! Hippos are actually closest related to whales and dolphins. With this up-close view you can really examine them to see some of the similarities they have with their relatives.

The training at the underwater viewing area is still in the early stages, but the hippos and trainers are enjoying this new level of interaction. Come by Simmons Hippo Outpost to see Adhama and Boipelo in action!

Dallas Zoo’s Simmons Hippo Outpost closed for maintenance

With winter in full swing, we’re taking advantage of the cold weather to perform maintenance on the Simmons Hippo Outpost – the zoo’s newest habitat that opened in April 2017.

No otters will be harmed or put to work during this maintenance project. 😉

The maintenance project will take about 6-8 weeks to complete, which means the hippo pair, male Adhama and female Boipelo, will remain behind-the-scenes during this time.

“Since we keep the hippos inside their warm barn when the outside water temperature drops below 60 degrees, we saw this timing for maintenance as a way to minimize any inconvenience to our guests,” said Harrison Edell, Vice President of Animal Operations and Welfare. “The hippos are receiving the best care possible during this period, getting extra enrichment items to keep them stimulated, and enjoying access to their private outdoor yard for extra exercise when the weather allows.”

Maintenance to Simmons Hippo Outpost will include repairs to the 24-foot by 8-foot underwater viewing window, which was recently damaged while a contractor was performing upkeep to one of the two viewing panels. Maintenance staffers will replace both panels with an acrylic that will be easier to maintain.

The 4,485-square-foot Highland Hippo Hut learning and event space will remain open during this time. Guests can also visit the okapi in the special encounter area where they can meet the stunning, endangered animals up-close during the daily 2:15 p.m. keeper chat (weather permitting, of course).

We promise to keep you up-to-date on the reopening of the habitat on DallasZoo.com and our social media platforms.

The Dallas Zoo opened the $14 million, 2.1-acre Simmons Hippo Outpost on April 28, 2017; the habitat was funded solely with private donations.
