Texas Rescue: 10 Years Later

Maroo, a male red-necked wallaby, passed away on November 11, 2019. Although this may seem like a sad way to begin a blog entry, this is a celebration of Maroo’s life for the almost 10 years he lived at the Detroit Zoo. He was part of the wallaby mob living in the Australian Outback Adventure, and seemed to enjoy exploring this expansive space and sharing his time with others of his species. He was cared for by dedicated zookeepers and observed by attentive volunteers as well as visitors. Maroo will be missed. His story could have had a much different trajectory, had it not been for the intervention of the Detroit Zoological Society (DZS).

TR Maroo

In December of 2009, six DZS animal curators and supervisors travelled to Texas to provide expert care for more than 27,000 animals seized by authorities in the largest exotic animal rescue in the history of the United States. We were contacted after an investigation revealed inhumane treatment of these animals – including spiders, reptiles, amphibians and numerous exotic mammal species – by an exotic animal dealer who was selling them. Our staff members spent almost two months at a temporary care facility in Dallas, helping to triage and care for these animals who had been kept in dismal conditions. Not only did this include basic care, such as proper food, water and medical treatment, but it was also the first time any of these animals were treated with the respect they deserve. Unfortunately, many did not survive due to the illnesses and injuries they sustained during the time they spent as part of the exotic animal trade.

Hundreds of these animals – 961 to be exact – about two-thirds of which were amphibians, came to the Detroit Zoo to spend the rest of their lives in comfort and receive the care each one deserved. Although many of these animals have passed due to old age over the past decade, some are still at the Detroit Zoo and Belle Isle Nature Center. Two ring-tailed lemurs were among the animals rescued, and the female was actually pregnant at the time. She gave birth to healthy twins, and all four still live in the group you can observe at the Zoo. Four Linne’s sloths were cared for by our staff and have gone on to live good lives at other zoos accredited by the Association of Zoos & Aquariums. Of the four matamata turtles who arrived here, one can still be seen at the Holden Reptile Conservation Center. You can also visit two tiger salamanders at the Belle Isle Nature Center. In total, there are about three dozen of the rescued animals still living in our care. Five wallabies originally joined the mob at the Detroit Zoo as part of this important rescue effort, and Maroo was the last of this group.

Maroo’s story is a great example of the impact the DZS has on the lives of individual animals. The exotic animal trade is not only having drastic impacts on populations of wild animals, it is also an industry that creates and promotes severe animal welfare issues for individual animals. Our mission is Celebrating and Saving Wildlife, and our efforts to assist with rescues and provide sanctuary for animals are a critical part of this mission. The next time you visit the Detroit Zoo, look for signs identifying rescued animals and learn more about their stories.

Meet Keti, An Adorable Baby Red Panda

Visitors to the Detroit Zoo are always excited when they are able to see baby animals.  Babies are adorable, and are often playful and fun to watch.  Chimpanzee Jane is no exception – she is now 15 months old and can be seen climbing in the trees in her habitat and encouraging the older chimps to play with her. Hana, a female Japanese macaque, is only 5 months old, but is already moving away from her mother and exploring the rocks and branches of her habitat.

It’s not always possible for zoo babies to be cared for by their mothers for various reasons, and occasionally animal care staff have to step in and assist.  When this happens, babies are often cared for in the animal hospital nursery, where they can be given the intensive care they need to grow and thrive.  In the nursery, veterinary and zookeeper staff caregivers can provide round-the-clock feeding and attention.

7-11-19

Over the years, we have had the pleasure of caring for a number of adorable babies, but in my opinion our current nursery resident – a female red panda cub – is arguably the most adorable animal in Detroit Zoo history.  She was born July 6, and weighed 112 grams (around 4 ounces), a good weight for a red panda cub.  While the cub’s mother Ash was pregnant, she allowed us to ultrasound her abdomen while she happily ate treats, so we knew she was pregnant with a single cub that was growing well.  Ash delivered the baby with no problems, and showed the newborn lots of attention, but this was her first pregnancy, and she didn’t have all of the skills needed to raise the cub.  Red panda cubs have been hand-reared at several zoos, including the Detroit Zoo, and we had prepared in advance to care for the panda cub, just in case.  A hand-rearing manual that compiles collective experiences of zoo professionals was used to determine the formula and feeding schedule and help to develop a care plan.

7-11-19 bottle

The cub was placed in an incubator that provided a warm, humidified environment, and was given round-the-clock care.  Her formula was offered in a small bottle with a nipple used for premature human babies, and during her first days she was given only 3-4 milliliters at a time. At each feed, we used a warm, moistened cotton ball to stimulate her to urinate and defecate.  We fed her eight times each day, and by one week she had gained 19 grams.  By two weeks, she only needed to be fed seven times a day and had nearly doubled her birth weight.  When she was a few weeks old, we were concerned that she might have a respiratory infection, but since then she has remained healthy and has continued to grow and become more curious about her environment.  At 5 weeks old, we warmed up the nursery room and moved her to a covered playpen so she could have room to move and play with toys.  A month later she was ready to be moved to an even larger area, and to be given access to climbing structures, bamboo to chew and manipulate, and bowls of formula mixed with adult diet.  She was given the name Keti, meaning “girl” in Nepali, and her caretakers spent time with her each day, encouraging her to climb and explore.

6 weeks

Keti is now more than half the size of an adult red panda, and spends time outside in an area designed to encourage her to play and practice her climbing skills.  She is also becoming acclimated to the colder temperatures.  Eventually she will be moved to a habitat where visitors can watch her continue to grow and get experience climbing and traveling at greater heights.  When proficient, she will be ready to join Ash, dad Ravi and grandma Ta-Shi in the Holtzman Wildlife Foundation Red Panda Forest.

Notes from the Field: Protecting Amphibian Biodiversity in Peru

You heard recently from one of our education experts about how the Detroit Zoological Society is working with Peruvian schools to conserve the rainforest through outreach and education. Conservation of the biodiversity in the Peruvian rainforest has been a priority of the Detroit Zoological Society for over a decade, and we have many programs in the rainforest that help to achieve this goal. One of our programs focuses specifically on amphibians, and that is where I have the great fortune to visit this incredible location.

Boana calcarata

There are over 600 species of frogs in Peru, with more species discovered every day. With this high number of species, Peru is called a “biodiversity hotspot.” These “hotspots” are very important to monitor for changes, because while there are many species they are all very dependent on one another. Small changes can cause drastic effects. Amphibians are some of the most sensitive animals, because their skin absorbs everything in the environment. If amphibians begins to get sick or have difficulty surviving, that is an excellent clue that something is wrong in the environment. All over the world, amphibians are currently having difficulty with changes we are seeing in the environment- because we are seeing global changes, it is extra important to study the animals in areas like the Amazon, where amphibians are in higher concentration, to try and understand patterns in these changes.

The convict tree frog (Boana calcarata) is a frog found in the Napo River region. This sound recording and image were made by the National Amphibian Conservation Center during a survey.

In order to keep an eye on the amphibians in the Peruvian Amazon, staff from the Detroit Zoo’s National Amphibian Conservation Center conducts surveys for frogs twice a year. This means we physically go out and look for frogs. Because we know we cannot possibly see all the frogs, also record the songs of frogs at night. Hearing the songs can help us guess numbers of animals singing and help us to hear the songs of species that are difficult to find on visual surveying. In addition to surveys, we monitor weather data in the Napo River valley. We have our own weather station that collects year-round information about the valley region. We also use small data loggers to collect immediate, specific “microclimate” changes where we visualize species breeding (for example: on a specific plant or under leaf litter). The weather data helps us understand both immediate changes in behavior of frogs, as well as changes in populations over time.

While data collection and surveying are important, fostering appreciation of animals in the local community is the primary goal of the visits to Peru. Our hope is that educating the community and creating excitement in future generations will help to preserve these animals for the future. The “Club de Protectores de Anfibios,” or Amphibian Protectors Club, is a club comprised of high school students that are local to the Napo River valley region. The club was founded in order to help impart enthusiasm for amphibians and the environment.

In Peru, there are many misconceptions surrounding frogs. There is a general belief that frogs are bad luck and should be kept away from homes. When the Detroit Zoo staff visited the Amphibian Protectors Club in June of 2019, the club members taught us how the Amphibian Protectors Club is changing the community. The club members performed a play in which they explained another local belief is that a woman will become pregnant if she spends time around frogs. Told from the perspective of high school students, this was a chilling superstition. Through the play, the students explained that by participating in the club they have learned not only that this is a myth, but also frogs are important for human health and humans need to protect frogs. The club members have taught their friends and families frogs are important and have begun to see more frogs in their villages since this change in attitude.

The students from the club went on an overnight excursion with the National Amphibian Conservation Center staff, where we visited one of our regular field research sites. We took a late night hike in order to see frogs calling and breeding at this special location. At this site, we saw species of frogs the students do not commonly see in their villages. After a good night rest, the club rose early in the morning to hike to the nearby canopy walkway- a breathtaking experience where the club members were able to look down on the rainforest from the treetops. While these students live in the rainforest, many of them have not seen their tropical home from this perspective. They were inspired by this view, observing the unique habitat of rare and diverse species. One club member called it “the view of the animals,” and asked very advanced questions about some of the plants and insects he observed.

This was an incredibly rewarding trip. The students showed us that their appreciation for the amphibians is making a difference. While I will not see them in person for a few months, the students will continue to speak with me over a WhatsApp chat (they named our group “Whatsappos,” because “sapo” means toad in Spanish). While I am away, the club meets monthly to survey in their home towns and the students will send me photos and descriptions of frogs the see. Over the app, we talk about the species and have a question and answer session. Their excitement is inspiring and infectious, and I am confident their enthusiasm will be what helps save species.

Animal Welfare: Welfare Assessments

One of the goals of the Center for Zoo and Aquarium Animal Welfare and Ethics is to conduct and facilitate animal welfare assessments. In some cases, this entails conducting scientific research aimed at answering questions such as how animals respond to changes in their habitats or modifications to the ways in which we care for them.  For example, and as you may have read about in previous blog entries, we assessed the impact of new or expanded habitats on the welfare of Madagascar giant hog-nosed snakes, penguins and grizzly bears at the Detroit Zoo, just to name a few. We also pose questions related to providing animals with stimulating experiences that allow them to engage in species-appropriate behaviors, such as increasing exploration in aardvarks and enhancing natural feeding opportunities for species like seals and gorillas. The more we can learn about how our animal care and management practices influence the welfare of animals, the more we can do to ensure they are thriving.

Although multi-faceted studies like the ones mentioned above are an important part of this endeavor, developing means to more rapidly evaluate the welfare status of individual animals is also a critical goal. Welfare assessments therefore also take the form of proactive and ongoing monitoring that provides an overview of the current welfare state of individual animals. To that end, the Detroit Zoological Society developed a welfare assessment tool in 2014 which was made freely available in a peer-reviewed publication in the Journal of Applied Animal Welfare Sciencein 2015. If you would like to read the full article, please visit our resource center on the CZAAWE website at czaw.org/resources and click on the link for A Universal Animal Welfare Framework for Zoos.

Since that time, we have continued to refine the animal welfare assessment tool to evaluate how the animals living at the Detroit Zoo and Belle Isle Nature Center are faring, as well as train other accredited organizations in the use of the tool. In its present form, the assessment tool includes measures of inputs, which focus on what is provided to animals, such as amount and complexity of their space, the social opportunities they have and their dietary considerations. The tool also incorporates measures of outputs, which are how the animals respond to what is provided to them. We try to make sure that we have output measures that match up with the questions about the inputs. For example, the outputs we would use to correspond to the inputs I listed as examples would include questions about how the animals use their habitat, if they interact with other animals that share their space in the manner we would expect and if they are in good body condition. The questions in the animal welfare assessment tool line up with the Five Domains model of welfare, which delineates how nutrition, physical health, behavior and the environment (both physical and social) feed into an animal’s emotional state.

Organizations accredited by the Association of Zoos and Aquariums (AZA), which we have been a member of since 1985, continue to place increasing importance on ensuring animals in their care are experiencing positive welfare, and this responsibility is reflected in the very standards by which member organizations must abide to be accredited. One of the newer standards requires AZA members to have a welfare assessment process like the one the Detroit Zoological Society has in place. It is great to see that our professional community is committed to not only provide good care for animals, but to provide them with great welfare.

DreamNight – A Night to Remember

The Detroit Zoological Society hosted more than 500 guests for DreamNight, a private nighttime event for families that include a child with special needs or chronic illnesses. The goal of this event was to provide an opportunity for families to spend time, all together, in a stress-free environment. This was the first event of its kind held at the Detroit Zoo, and we were delighted with the reception of the event as well as the outcome.

Screen Shot 2019-08-12 at 2.55.10 PM

DreamNight brought families to the Zoo from around Michigan and parts of Canada. Excited and happy faces emerged as guests walked through the front gates. Without the crowds, many were able to make observations of the animals and experience the Zoo, without being overwhelmed. Penguins were a huge favorite with kids and adults alike. Some children needed the quieter buildings to enjoy the animals who live in the Polk Penguin Conservation Center, National Amphibian Conservation Center or Arctic Ring of Life.

Screen Shot 2019-08-12 at 2.56.46 PM

We saw looks of pure joy as children, for the first time, watched penguins swimming. Parents showed relief on their faces as they observed their children watching the animals or exploring the hands-on opportunities. Entire families explored activities together  ̶̶  talking and playing through their shared experiences. We were also grateful for an excited group of staff and volunteers, ready and willing to support each family as they explored the Zoo.

Throughout the event, families enjoyed dinner, courtesy of Service Systems Associates (SSA), our catering partner, who donated a vast majority of the food and labor for the evening. Stations with hands-on activities were spread throughout the Zoo, which invited guests to explore butterfly wings with handheld microscopes or play with sand in front of the camel habitat or weigh out food for an otter’s diet. Face painting, donated by Kaman’s Art Studio, was also available for all who attended. Our Zooper Hero mascots celebrated with us, and were loved by the families in attendance. Many children danced along to the music from a live band and watched a sensory-friendly version of the 4-D movie in the theater.

Screen Shot 2019-08-12 at 2.57.07 PM

We had an amazing time meeting these wonderful families and getting to know them. The Detroit Zoological Society strives every day to ensure that our entire community is welcomed within our organization. We have recently been certified through the The KultureCity® Sensory Inclusive™ program, which helps us to think strategically about how we can prepare guests before they arrive and provide a positive experience while they are here. Staff and volunteers have participated in training to be aware of our guests needs and learn strategies for supporting them during their visits. Sensory-friendly bags, which contain headphones, fidget items and a feeling thermometer, are available to be checked out to use throughout the Detroit Zoo and Belle Isle Nature Center. We look forward to hosting future events like DreamNight and ensuring that all families can experience the Detroit Zoo.

Becoming an Eco-Friendly Consumer – How to Spend Your Green on What’s Truly Green

In recent years, businesses have caught on to the fact that “green” sells. In fact, it has been found that products that are sustainable sell better than those that are not. It’s no surprise that the number of eco-friendly products on the market has increased dramatically. However, some companies are guilty of “greenwashing,” a marketing tactic used to make a company appear environmentally friendly when in reality their practices are far from it. With all these new, green products in the marketplace, it can be difficult to know which ones are truly good for the environment. Here are a few tips on how to become an eco-friendly consumer yourself:

  1. Check the Contents

The easiest way to tell if a product is eco-friendly is to check its contents. Here is a list of eco-friendly materials to search for:

  • Recycled or Upcycled: Many companies are turning trash into treasure by using recycled materials or upcycling old materials to make their merchandise. From shoes to backpacks, toys to yoga mats, many of the products we use every day are made from recycled materials. Even fine art is created through upcycling, like the one-of-a-kind sculptures found in the Snares to Wares: Capacity for Change exhibition at the Detroit Zoo. The Snares to Wares initiative upcycles illegal, inhumane snare traps from national parks in Uganda and turns them into sculptures of the animals that could have been trapped in the snares. The sculptures are then sold, providing much-needed income for the Ugandan artists. This is a great example of how repurposing materials can benefit not only the environment but also the lives of animals and humans.

Snares to Wares.jpg

  • Organic: The non-organic agriculture industry uses pesticides and fertilizers that have negative impacts on the health of the environment, wildlife and humans. Organic products are those produced without these harmful substances. Though we typically associate the term “organic” with fruits and vegetables, it can apply to plant-based materials found in fabric and beauty products.
  • Natural Over Synthetic: While some items can’t be organic, choosing ones made from natural materials instead of synthetic that take thousands of years to decompose is the better choice. Clothing and other textiles can be made using materials such as hemp, soy silk/cashmere, cotton and linen. Bamboo is another great material because the plant doesn’t need fertilizer or pesticides, is biodegradable and requires little water. Eating utensils, toothbrushes, “paper” towels, flooring, furniture and even bed sheets can be made from bamboo.
  • Locally Sourced: The amount of travel it takes for most of our products to reach the shelves results in a tremendous amount of harmful emissions along the way. By choosing to purchase items that are locally sourced or made from locally sourced materials, you can significantly reduce the environmental cost of shipping.
  1. Read the Labels

There are many products that claim to be made from all-natural ingredients and advertise themselves as eco-friendly, but one of the only ways to really tell is to read the product’s label for yourself. Go through the ingredients and make sure that if they’re claiming to be natural that only natural components are listed or at least are the very first ingredients. Also, look for labels that certify that the product is eco-friendly such as the USDA Organic Certified label or the EPA Safer Choice label that signifies the product’s ingredients and manufacturing process have met stringent government standards for our health and the environment.

  1. Find the Right Company

Making sure the company you are purchasing from follows environmentally safe practices is just as important as their products being made from eco-friendly materials. Just like individual products can be green-certified, so can entire corporations. One of the most prominent certifications is the B Corps certification; Certified B Corporations are businesses that “meet the highest standards of verified social and environmental performance, public transparency and legal accountability to balance profit and purpose.” A searchable list of Certified B Corps is found on their website, making it simple to find eco-friendly shopping opportunities. Another helpful resource is the World Fair Trade Organization; WFTO members are verified fair trade enterprises. Their products adhere to the 10 Principles of Fair Trade, Principle 10 being “Respect for the Environment” which stresses the importance of a circular economy (upcycling) and organic agriculture. The WFTO website also features a search engine to help you find fair trade products and businesses.

IMG_9670.jpg

The right, eco-friendly business may be closer than you think –in 2019, the Trading Post, a retail concession featuring all sustainable merchandise, opened at the Detroit Zoo. The store, itself made from a re-purposed shipping container, features eco-friendly and fair trade products from all around the world. Stop by the Trading Post on your next visit to the Detroit Zoo to purchase eco-friendly souvenirs!

Animal Welfare: Grizzly Bears Really Dig Their Expanded Habitat

As part of the Detroit Zoological Society’s (DZS) commitment to ensuring individual animals experience great welfare, a significant expansion of the grizzly bears’ habitat was undertaken in 2018. The male grizzly bears living at the Detroit Zoo, Mike, Thor and Boo, are brothers who were rescued in Alaska after their mother was killed and the cubs began foraging too close to humans. At approximately one year of age, they were too young to properly care for themselves and the DZS provided them with a safe place to grow up. The bears are now eight years old and weigh approximately 900 pounds.

grizzly grass.jpg

The expansion doubled the amount of space for the bears and also increased the number of environmental features in the habitat, including caves and substrates such as grass and mulch. When we make changes that affect the lives of animals, it is important that we understand how those changes impact them. To that end, we collected data the fall prior to construction to obtain a baseline of the bears’ behavior and hormone levels. Observations continued during construction and ended two months after the bears moved back into their renovated home. Zookeepers also filled out surveys and collected fecal samples each day.

We were happy to see that, in general, the construction itself had little impact on the bears. We had the zookeepers keep track of things like appetite and interest in participating in positive reinforcement training, and the bears did not show any changes to these behavioral indicators of welfare. Additionally, their glucocorticoid concentrations did not change during construction, suggesting that the bears did not perceive this to be a stressful time period. We did see some fluctuation in how much time each bear was visible outside, depending on how loud the construction activities were. Only one of the bears, Mike, spent more time inside (and out of sight) when the construction noise reached higher levels. Individual animals, just like people, perceive experiences differently, and therefore may react differently.

When we compared how and where the bears spent their time before and after the expansion, we had some interesting results. The bears made use of all of the substrates and features in the expanded habitat. They were very excited to gain access to a mulberry tree that had previously been part of one of the side bear habitats. Mulberry is enjoyed by many species at the Detroit Zoo and the grizzly bears are no exception. Mike very industriously spent time trying to uproot the tree to make it easier to eat all the delicious berries! All three bears also enjoyed digging up, excavating if you will, various sections of the habitat. One thing that did not change was Thor’s affinity for his rock “pillow”. There is a large boulder-sized rock formation high up in the original habitat space on which you can sometimes find him resting his head. Thor still very much enjoys giving the rock a bear hug as he catches up on some sleep!

grizzly cave.jpg

Not only did the expansion mean the bears had more environmental choices, but the additional features had an impact on their social dynamics as well. With more space and more options within that space, the bears could spread out and all spend time in areas that met their needs, rather than sharing, or having to wait to use the features. This also translated into even more positive relationships between the brothers. We did see Boo practice his best “little brother” moves in the expanded habitat. He will come as close to Mike as possible until Mike finally swats or chases him away. I definitely experienced that with both of my little brothers growing up! It is possible that with more space, Boo enjoys getting a reaction from Mike and having plenty of room for the game of “catch me if you can” that may follow.

The expanded space has given the grizzly bears more behavioral opportunities and the ability to make more choices about how and where to spend their time, as well as how much of that time they want to spend near one another. The DZS is always striving to create habitats that promote great welfare and increased choice is an important part of that.
