Have you ever looked into an animal exhibit at the Boonshoft Museum or another zoo and wondered what all of that stuff is in there? Boxes, bags, shredded paper, hay, plastic balls,
why are the animals playing with trash?
Well, what’s one person’s trash is another animal’s treasure! Have you ever looked into an animal exhibit at the Boonshoft Museum or another zoo and wondered what all of that stuff is in there? Boxes, bags, shredded paper, hay, plastic balls…why are the animals playing with trash?
In addition to making sure the animals in the zoo have food, water, and clean habitats, zookeepers also provide enrichment for the animals under their care.
The Boonshoft Museum of Discovery is a member of the Association of Zoos and Aquariums, or AZA. The AZA is a nonprofit organization dedicated to the advancement of zoos and aquariums in the areas of conservation, education, science, and recreation. AZA represents more than 200 institutions which meet the highest standards in animal
care, provide a fun and educational family experience and dedicate millions of dollars to scientific research, conservation, and education programs. This means that even though the Discovery Zoo is not nearly as big as the Cincinnati or Columbus Zoo, the animals receive the same quality of care that they would at a larger institution.
The AZA defines enrichment as: “a process for improving or enhancing zoo animal environments and care within the context of their inhabitants’ behavioral biology and natural history. It is a dynamic process in which changes to structures and husbandry practices are made with the goal of increasing behavioral choices available to animals and drawing out their species-appropriate behaviors and abilities, thus enhancing their welfare. As the term implies, enrichment involves the identification and addition within the zoo environment a specific stimulus that the occupant wants or needs but which was not previously present.”
This is basically a long and complicated way of saying that zookeepers provide our animals with activities to promote their natural behaviors, and to keep them mentally and physically active. Life in the wild is really tough, and animals spend all their time fighting to survive. Most animals spend around 80% of their time foraging for food! Finding food isn’t easy, predators often spend hours stalking their prey, and sometimes they aren’t successful. Many herbivores eat plants that are low in nutrition, so they have to spend most of their day grazing.
Animals in the zoo don’t have to worry about predators, disease, finding food, drought, or natural disasters. Since life in the zoo is a little easier, zoo animals usually have more free time than they would in the wild, and zookeepers try to fill up this free time by providing their animals with enrichment. Enrichment can be almost anything; mulch, rearranging logs and rocks, scents, snake skins, puzzle feeders, and paper bags are just a few examples of enrichment done at the Discovery Zoo. When providing animals with enrichment, zookeepers take into account the natural history of that animal, or how it lives in the wild. For example, bat-eared foxes have great hearing to listen for insects digging under the ground, so keepers will put crickets and mealworms in paper bags full of hay. The foxes use their huge ears to listen for the bugs and then tear into the bags for their reward.
When building exhibits, enrichment will often be built in. In our meerkat exhibit, one of the big termite mounds actually has a network of tubes inside that we can put crickets into. The tubes are like a maze and make it so the crickets take a long time to get out, so they’ll drop out randomly throughout the day. This is a great way to keep our meerkats active since they’ll investigate the termite mound many times during the day to see if any more crickets have fallen out. Wild meerkats spend their days foraging for insects, rodents, and other animals, so feeding them in this way helps them to express that natural behavior.
A good enrichment program tries to stimulate all of the animal’s senses: hearing, sight, touch, smell, and sound. At the Boonshoft Museum, we provide our animals with a variety of different scents; spices, fruit extracts, and even scents from other animals. We play bird calls and other nature sounds for a lot of our animals, and our screech owl Houdini even called to a recording of a screech owl. Something we do for a lot of our animals is put their food in a puzzle feeder or a toilet paper tube. The animal will use its sight and smell to investigate the object, and then use touch to get the food out.
Enrichment isn’t limited to animals in zoos, you can also enrich your pets at home. Commercially available puzzle feeders are a great way to slow down a fast eater or to keep your dog busy when you’re away. Catnip is a great example of scent enrichment that can be used for cats at home, and your cat may even like other spices that are in your kitchen. Whenever giving an animal enrichment, it’s important to research and make sure that it is safe for the animal.
Join us at the Boonshoft Museum of Discovery on Saturday, February 18 for our first-ever Enrichment Day from 10am-4pm. See our Discovery Zoo residents get some awesome enrichment, learn more about enrichment at activity tables, and meet some of our ambassador animals! Do you love an animal in the Discovery Zoo? We will have enrichment “Valentines” with presents you can get for your favorite animal!
