Animal Welfare: What is a Warthog Thinking?

The Detroit Zoological Society’s Center for Zoo Animal Welfare (CZAW) has been hosting workshops to train other professionals around the world to assess and improve animal welfare each year since 2012. In that time, more than 50 people have come to the Detroit Zoo to learn more about the ways in which animals are impacted by living in captive settings, and how to address the challenges they face. This year is no different. Another class is here spending five days with us and participating in lectures, discussions, group projects and exercises in the Zoo.

One of the most fun and impactful activities might sound a little silly. We ask the participants to walk around the warthog habitat, first as a human, then as a “warthog”! Every species – and really every individual –experiences the world in different ways. When they are being warthogs, the participants crawl around while wearing goggles that occlude their vision. This is to simulate what it might be like for a warthog living in the habitat, as they rely less on vision than humans do, and to allow each person to get a better sense of how different the world is from the perspective of another species. Once we start to ask ourselves how the animals experience the world we have created for them, we can truly begin to understand what is working for them and what may need to be improved.

Warthog - Roy LewisOne of the goals of CZAW is to provide animal welfare training, and although it is a whirlwind of activity, it is incredibly rewarding for our staff. Not only do we get to meet others who have the same desire to improve the welfare of the animals for which they care, but we get to play a part in helping them to make animal welfare a priority at their own institutions.

Animal Welfare: Preventing Bird Strikes

Stephanie Allard, Ph.D., is the director of animal welfare for the Detroit Zoological Society and oversees the Center for Zoo Animal Welfare.

Getting to see nature up close and personal Photo by Patti Truesdellis amazing – especially birds, which many of us are able to do from the comfort of our homes. I love to bird watch, and I have bird feeders at my house, as I’m sure many of you do. I enjoy seeing birds as they fly around, forage for food, interact with each other, and raise their young. We have bird feeders at the Detroit Zoo and Belle Isle Nature Zoo as well, which attract many airborne visitors.

We have to be vigilant, however, because we want to protect these incredible species as we invite them to join us in our outdoor spaces. Millions of birds are killed each year in the U.S. alone because of structures that are built by humans, and among the main culprits are windows. They let in light and they provide us with views, but they also confuse birds and create a very dangerous situation.

Humans and birds have very different visual systems, and what appears to us like a see-through barrier does not look that way to birds. The glass appears invisible to them and often acts as a reflective mirror. Because they can’t see the glass, birds will often fly into a window. This is a deadly phenomenon known as “bird strike”.

Photo by Patti TruesdellWindows are not a new threat for birds; however, this serious animal welfare and conservation issue does not get as much attention as it should. There are programs designed to bring attention to bird strikes and reduce the impact on birds, including the Lights Out program. There are also individuals who have devoted their careers and lives to the issue, such as Dr. Daniel Klem Jr., an ornithology professor from Muhlenberg College who spoke about his decades of work on this topic at the third International Symposium on Animal Welfare hosted by the Detroit Zoological Society and our Center for Zoo Animal Welfare in November of 2014.

The great news is that there are things we Photo by Jennie Millercan all do to help prevent birds from suffering. We can put up bird silhouettes on our windows (you will see many on the windows throughout the Zoo), or reflective tape. There is even special film and glass that can be installed that takes advantage of the fact that birds see in the ultraviolet range so that windows that seem clear to us are now seen by birds as real barriers. Photo by Jennie MillerIf you have bird feeders, don’t put them further away from your windows than 3 feet. This means that birds can come enjoy the food, but won’t gain enough momentum to harm themselves if they take off towards any windows. Use your blinds if you have them – this also lets birds know that they can’t fly through.

We truly have the ability to make a difference in the lives of individual birds that share the world with us, and in turn, help protect their species.

Animal Welfare: A New Home for Wolves

Stephanie Allard, Ph.D., is the Director of Animal Welfare for the Detroit Zoological Society and oversees the Center for Zoo Animal Welfare.

She was standing still, in front of an expansive vista full of greenery. Her eyes bounced from place to place, noting the tiered stream and pools, the variety in shrubbery and trees, and the rocky outcroppings. Sensing movement to her left, she turned to get a better look, and, through the trees she spotted Kaska, a male gray wolf with a coat of dark, smoky fur, exiting the den.Wolf - Wazi - Lee Fisher

Wazi, a 7-year-old female gray wolf, is often seen exploring the terrain of her new home in the 2-acre Cotton Family Wolf Wilderness. Since it’s opening in early June, staff from the Center for Zoo Animal Welfare have been observing what the two wolves are doing and where they are spending their time as they acclimate to their new habitat at the Detroit Zoo. As the wolves interact with each other and explore their surroundings, we learn what matters to them.Cotton Family Wolf Wilderness - Jennie Miller

The process by which zoo habitats are designed is lengthy and meticulous. When architects design a home or an office building, they can talk to their clients to make sure that the design encompasses all of their wishes and meets all of their needs. When we are designing spaces for animals, we do not have the luxury of asking them questions directly. We have to rely on our understanding of the ecology and behavior of the species in question. We engage experts and ultimately construct habitats that we believe will not only meet, but exceed the needs of the animals that will inhabit them. We include opportunities for each animal to engage in species-typical behaviors, to seek shelter and privacy when desired, and to exert some measure of choice and control over their daily lives.Wolf - Kaska - Roy Lewis

When all is said and done, we must rely on what the animals “tell” us about their environment and make any adjustments accordingly. As we do with all the animals, we will continue to find ways to learn what Wazi and Kaska think about their home and their lives.

Animal Welfare: Animals After Dark

Stephanie Allard, Ph.D., is the Director of Animal Welfare for the Detroit Zoological Society and oversees the Center for Zoo Animal Welfare.

Have you ever wondered what the animals do at night when the Detroit Zoo is closed? Some animals, like gorillas and lizards, are most active during the day – known as diurnal – others, like aardvarks and beavers, are most active at night – known as nocturnal – and some have other activity patterns.Kaatie the aardvark - Patti Truesdell

It is important for us to understand the activity patterns of the different animals that live at the Zoo because we have a responsibility to meet their needs all of the time – not just when the Zoo is open to our visitors during normal business hours. For some species, there is already a lot of information available about when they are active and when they spend more time resting. This can help us plan how to best provide them with the opportunities they need to thrive. For others, it can be helpful to monitor their behavior so that we can make informed decisions about each individual animal’s care and welfare.

Jabari the giraffeGiraffes are a good example of this, as it is a species that sleeps for short durations several times a day. In the wild, giraffes need to be constantly on alert for predators. Since this is not the case in a Zoo setting, the sleep and activity patterns of giraffes vary, therefore we wanted to determine what they were for the giraffes here. We spent time monitoring the behavior of the 7-year-old adult male giraffe, Jabari, and the 6-year-old female giraffe, Kivuli, during the night and found that they do spend periods of time resting and ruminating. However, they do have activity peaks as well. Having this kind of information presents us with the chance to develop ways to provide them with things like additional foraging and feeding opportunities throughout the night, which we have done.

It is so important that we always seek additional knowledge to help us ensure that the needs of all the animals who call the Zoo home are met, even when we are not there to see it.
