What
is enrichment? Enrichment is part of the Zoo's mission of inspiring
others to join us in caring for animals and conserving the
natural world.
Enrichment is the addition or modification
of an animal's environment that encourages the animals to
make choices, exhibit natural, or species-appropriate behavior,
presents mental challenges, encourages physical activity/exercise
and enhances the animal's overall well being.
An animal's life can be enriched in a variety
of ways. Enrichment often takes the form of modifications
to exhibits. This provides animals with additional three-dimensional
space for climbing and resting . It also provides visual barriers
from cagemates as well as the public, which can help to alleviate
social pressures. Viewing platforms can be built into exhibits,
allowing carnivores the opportunity to view typical prey items
in other areas of the Zoo.
So why is enrichment so important? In the wild, animals spend much of
their time hunting for food, building nests and warding off
predators. The animals at The Toledo Zoo are provided with
the highest quality of care. This means they are fed well
balanced diets that include ample amounts of food, they receive
regular medical exams, and they are free from predation. Often,
that very quality of care can discourage the animals from
exercising some of their natural behaviors and talents, since
they're no longer necessary. A well-rounded enrichment program
can provide the animals with activities that simulate these
natural behaviors. More specifically, a well thought
out enrichment program can also
Increase animal activity and exercise
Decrease the occurrence of stereotypical
and other aberrant behavior by directing animal energy into
more productive activities
Provide the animals with choices and control over certain aspects of their environment (what to eat, temperature and lighting gradients, whom to interact with, etc.)
Improve breeding success and conservation
efforts by housing animals in appropriate social groups
that allow for normal physical and psychological development
Increase visitor appreciation by displaying animals in stimulating and naturalistic environments, allowing guests to view the animals in situations that mimic those of their wild counterparts.
Enrichment is an integral part of daily
animal care. That animals need stimulation and opportunities
to make choices in their environments is no longer a question.
It is now a new challenge facing animal caregivers to provide
the animals with environments that meet all of their physical
and psychological needs. Enrichment comes in many forms, whether
variety within their habitat, food, scents, items to manipulate,
investigation, and even animal training.
The video above shows some enrichment items
being prepared, and various animals interacting
with enrichment items in their exhibits.
These poison dart frogs will chase the pinhead crickets that emerge from this cardboard tube feeder. The crickets hide in the substrate, encouraging the frogs to search for them throughout the day.
Cinereous vultures have sharp beaks
that tear into flesh. Keepers hide the food (usually whole
rats) in cardboard boxes or paper bags to increase the time
and complexity of feeding.
