Celebrating National Zoo Keeper Week 2023!

By Mary Humbyrd, coordinator of behavioral husbandry for the Detroit Zoological Society (DZS)

National Zoo Keeper Week starts annually on the third Sunday of July. Representative Susan A. Davis introduced House Resolution 509 on June 21, 2007. This resolution was proposed to encourage individuals on a national level to engage in programs, activities and ceremonies during National Zoo Keeper Week that encourage species conservation and public awareness of the important role of zoos in wildlife conservation.

It is an absolute honor to celebrate our DZS zookeepers. Zookeepers are a unique bunch and have many amazing talents not often seen by zoo guests. Our animal care team is creative, innovative and can build just about anything with some zip ties and duct tape. Zookeepers brave the hottest days of summer and the freezing days of winter. Animal care specialists are on a constant quest for knowledge to improve and raise the bar to provide the best care of the animals they adore. They are involved with the animals from birth to passing and build lifelong relationships. They have their heart and soul in the profession. Zookeepers are advocates, educators, scientists and enjoy sharing their passion with anyone and everyone they encounter. As no day is ever the same, zookeepers have an incredible ability to go with the flow — but with precision and accuracy. Their passion for all living things is inspiring and enlightens all of us who have the privilege of hearing their stories.

From ice cream socials and cookouts to food trucks and Tigers games, scroll through the gallery below to see how we celebrated the DZS animal care team this past National Zoo Keeper Week! 

Celebrate World Migratory Bird Day!

This week, hundreds of millions of birds will leave their winter habitats from as far away as the Amazon rainforest and Andes mountain range on their annual journey to reach their summer breeding grounds across North America and right here in Detroit! Migratory bird species travel along ancestral routes defined by waterways and often travel under the starlight at night. Fluttering along geographic landmarks like the Mississippi River and the shores of the Great Lakes, birds as small as the ruby throated hummingbird head to their summer homes thousands of miles further north. 

Saturday, May 13 is World Migratory Bird Day, which amplifies the critical importance for birds to have access to water throughout their journey.  Waterways serve as sources for food and habitat during migration and year round.  At the Belle Isle Nature Center, birds are celebrated on this day — and every day — through education and conservation practices that promote their right to access food, water and habitat. 

As the month of April came to a close, a time when the frequency of bird migration really picks up in the Detroit area, the Belle Isle Nature Center hosted Michigan Public Radio’s live broadcast event “Bird Nerds Unite.” This event featured a panel of local experts who discussed all things birds: the birds who are migrating through now, those who reside in southeast Michigan all year and tips for noticing birds right near your home.

You can watch or listen to a recording of the presentation here.

Even the youngest among us can appreciate the birds in their neighborhood. Don’t just take our word for it — here’s what Marlin Franklin, Brightmoor community engagement manager with Brilliant Detroit, had this to say about the Belle Isle Nature Center’s after school program, Neighborhood Nature Explorers. 

“Contrary to popular belief, bird watching is not boring! It is amazing fun for kids and adults,” he says. “We celebrated bird day at the Brilliant Detroit Brightmoor site with Micah Blake-Smith from the Belle Isle Nature Center. We learned the proper way to use binoculars. We identified birds that live and forage for food in our neighborhood, and we made feeders for those birds that we hung in the trees. Our little people will grow up to be good stewards of the earth with classes like these.”

If you think that’s something, come experience the excitement that awaits from bird watching during sunset or with the use of audio ID technology at the Belle Isle Nature Center’s free programs.

Nature at Night

A flutter of green, a jolt of red, a fleck of gold – a pheasant ducks through the underbrush in a burst of color. Whether it is the visual rainbow of feathers or a symphony of a bird chorus saluting the setting sun, hikers and bird watchers can find themselves knee deep in renewed prairie while birding on Belle Isle. Our Nature at Night program gives participants an opportunity to discover spaces that burst with life as the sun goes down. Join us for our next free hike from 5 to 9 p.m. Thursday, May 18. Guests are welcome to bring binoculars or borrow a pair from the Nature Center.

Science Hikes

More of a morning bird than a night owl? There is also a daytime Science Hike planned for 2 to 3 p.m. Sunday, May 21. This “technologically enhanced” bird walk utilizes the Merlin Bird ID app. Participants will be provided with iPads and can use the app to help them identify birds from their song. A recent walk on the Nashua Canal Trail, a 1-mile accessible pathway through the heart of Belle Isle, revealed ruby-crowned kinglets, red headed woodpeckers, white-throated sparrows and one very impressive eagle’s nest.

As spring bird migration winds down in June, the community group Black to the Land Coalition will host their annual birding event at the Belle Isle Nature Center called Blacks, Browns and Birds from 10 a.m. to 2 p.m. Saturday, June 3. This allows for Black and Brown families to come together in green spaces, connect with the land through bird watching and enjoy other outdoor activities.

For more information about upcoming, free programs and events, visit our website. The Belle Isle Nature Center is open seven days a week, and we are happy to give tips on where to head for your own bird walk. Celebrate World Migratory Bird Day on Saturday, May 13 or any day of the year by noticing where you find nature in your neighborhood.

Take Your Birding to the Next Level with eBird! 

Many golden-crowned kinglets use Zoo grounds during migration from the end of March just into May and from the end of September into the beginning of November.

Authored by Matthew Porter, bird care team member for the Detroit Zoological Society (DZS).

Happy National Bird Day! To celebrate, let’s talk about how the Detroit Zoo takes part in one of the greatest community science projects on earth, eBird. 

The website ebird.org is home to a giant database of bird observations run by the Cornell Lab of Ornithology. Through this website, there is an abundance of information about birds across the globe.

EBird brings together the community and scientists to understand the ranges and movements of birds around the world. Once involved, we are all scientists at work. This collaborative effort harvests a massive data set that would never be attainable without the efforts of everyone involved. Our efforts compiled together advance avian science and conservation worldwide. Last year, on a single day in October, more than 34,670 people from 185 countries reported 80,000 checklists observing 7,453 bird species!

Over the last couple of years, our staff has invested lots of time to help with this worldwide effort. What we have found is that there is more avian diversity than we previously thought at the Detroit Zoo. Some birds call the Detroit Zoo home year-round. Others come here to breed in the summer, while some come here for a winter home. Many species use the Zoo from March through May and August through November as a very important migratory stopover. This land is a green island in the middle of suburbia and a great, safe stopover refuge. Our buildings have bird-friendly glass, and we continue to plant native plants to provide the appropriate food and ecosystem many species need.

Last year, more than 100 species were reported by Zoo staff and citizen scientists surveying Zoo grounds. You can join in on the fun by signing up for an eBird account at ebird.org. The website has lots of information and tutorials on surveying and best practices. There is also an easy-to-use app that can make surveying more efficient. Once enrolled, you can become part of this worldwide effort to assist with bird conservation.

Here at the DZS, we are always looking for more ways to engage with the community so that people, animals and the natural world can thrive together.

A Song in the Darkness: Audio Loggers and Panama’s Imperiled Amphibians

Authored by Mark Vassallo, Detroit Zoological Society (DZS) Amphibian Department Supervisor.

The cloud forest of central Panama is a unique and mysterious place, full of rare creatures and plants that call these moisture-laden peaks home. At night, the jungle writhes with life as the nocturnal world takes over the mountainsides. In this veil of darkness and nestled in the elevations of these dense jungles, some of the earth’s rarest amphibian species reside. Many of these species are yet to be described by science, and others are considered to be extinct.  As I gazed up at the gathering rain clouds on the volcanic peaks of El Valle, I could not help but wonder which of these potentially extinct amphibians could still be out there.

I have been traveling to El Valle, Panama for the last seven years to work with the El Valle Amphibian Conservation Center (EVACC). This organization is run by Edgardo Griffith and Heidi Ross, a husband-and-wife biologist team, who have dedicated their lives to the conservation of Panama’s most endangered amphibians. Usually during these trips, I am undertaking projects involving the installation of life support and infrastructure or helping troubleshoot specific husbandry issues that arise in one of the modified shipping containers in which EVACC houses seven species of Panama’s rare and endangered amphibians, including the iconic Panamanian golden frog (Atelopus Zeteki). 

A Warzewitsch’s frog was identified in the area.

While those types of jobs are on the docket for this trip, we also have an important task to complete that will bring us into the upper reaches of the cloud forest in the hopes to hear a sound that could mean some hope for the imperiled amphibians of Panama. The sounds we are hoping to hear are the calls of thought-to-be-extinct amphibians, including Raab’s tree frogs (Ecnomiohyla rabborum), large and highly unique arboreal frogs who lays their eggs in tree cavities and can glide through the air to evade predators. In the last year, EVACC has begun the process of deploying audio loggers in some of the area’s hard-to-reach elevations to listen for the calls of amphibians like the Rabb’s tree frog that are widely thought to be potentially extinct. 

The audio loggers are sturdy boxes that contain a microphone, batteries and SD cards accompanied by a digital screen. The idea is that these listening devices, which are programmed to turn on during the dusk and nighttime hours, will pick up the call of one of these rare frogs. If a call from one of these frogs is detected on the logger recording, this would give the biologists at EVACC a very good lead on the areas where intensive surveys could take place to potentially locate this species.

Armed with some GPS coordinates, batteries, fresh SD cards and rough information about the audio logger’s location from a member of the last group who placed it, we headed up the mountain to start our journey. As we began to climb, the heat and humidity was intense — our clothes were soaked in less than an hour.  Large biting ants were swarming our boots as the incline steepened, and we came to a crossroads in the trail. We had reached the GPS coordinates but realized that these coordinates could not be correct. At this point, we decided to attempt to leave the trail and start climbing up what seemed like a cut in the dense jungle, which may have been caused by mudslides and heavy rains, certainly nothing even resembling an actual trail. The going was difficult as the clouds began to gather. Buckets of heavy rain soon began dumping on us, causing the mud to loosen and give, making the more vertical sections especially precarious. In addition to watching your footing in the jungles of Panama, it is also important to watch where you put your hands. Eyelash vipers and stinging insects of all kinds tend to rest on branches and sticks at about eye level. All of these thoughts were keeping our senses sharp as we broke through clearing after clearing, each time hoping that this was the top of the mountain and the audio logger would appear like a shining beacon amongst the dense jungle. Yet, each time the clearings revealed even more vertical walls of vines and thick jungle vegetation to climb. Our resolve was fading, but we pressed on. At one point, my balance gave way, and I fell face first into the side of the muddy slope. As I raised my head, I noticed I was face to face with a tiny gem of a frog. It was a blue-bellied poison frog (Adinobates minutus). This toxic little frog was just staring back at me, probably wondering why a silly, hairless ape had bothered to climb this far up a mountain during a thunderstorm. 

A rainforest rocket frog was identified in the area.

The rain was finally letting up, and this gave us a little boost as we could see some sunshine emanating from what looked like a break in the jungle ahead. As we approached, sharp painful sensations started overwhelming my hands and wrists. We were wading through a large column of sharp bladed grass, which when brushed against, caused a paper cut like lacerations on the skin. Once we emerged from the brush and into the clearing, we realized we had reached the top. The jungle was so dense there was no real spot to even look out to enjoy the view. We immediately got to work searching for the audio logger.  I looked left then right and passed through some thick brush. Then I saw it — a strip of white that stood out in the landscape of green. It was one of the zip ties used to attach the logger to the tree. We had found it! After several minutes of exulted celebrations and numerous high fives, we swapped out the SD cards and batteries, the unit was reprogrammed, and we locked up the protective case. The trip down was more like a ride down a luge course made of mud. This did make the process faster but certainly not any safer. 

Once we finally arrived back at the EVACC grounds, we were exhausted and coated in mud and insect bites but satisfied and content that we had achieved a seemingly insurmountable challenge. After a shower and a cold beverage, I walked out into the moonlight on the grounds of EVACC. Once again, the clouds were beginning to gather around the El Valle mountains, and my eyes settled on the tips of those green jungle peaks, wondering if the logger we had reset for another four months would record a sound of hope.

Flying High: Celebrating World Migratory Bird Day

It’s the most wonderful time of the year. No, not Christmas — bird migration season! It’s the time of year when birds who left Michigan during the winter months to find refuge in warmer states make their triumphant return. Look outside, and you are likely to see robins, Canada geese and sandhill cranes among the birds flying in the spring Michigan skies, happy to be back after a cold winter away.

While everyone at the Detroit Zoological Society (DZS) celebrates these birds every day, we are encouraging the public to join us in celebrating and raising awareness around the conservation of local species on World Migratory Bird Day (WMBD) May 14.

WMBD, formerly International Migratory Bird Day, is an annual campaign highlighting the need for the conservation of migratory birds and their habitats. Through a collaboration of festivals and events from partners across the globe, WMBD brings awareness to the threats migratory birds face, as well as the birds’ ecological importance and the need for bird conservation.

Sandhill crane, Patti Truesdell

While all aspects of bird conservation are important, this year the organizations behind WMBD are focusing on fighting light pollution and harm it can cause to migratory birds.

Light pollution, or the inappropriate or excessive use of artificial light, affects our world in numerous ways, from limiting our view of the night sky to disrupting human sleep patterns. However, light pollution’s most devastating impacts are felt by wildlife — and migratory birds are no exception.

Most birds migrate at night due to the calm skies and lack of predators. These birds use the moon and stars to guide their way — a system that has worked for eons. However, with light pollution encroaching further and further along the night sky (at a rate of increase of at least 2 percent per year, according to the Smithsonian Migratory Bird Institute), migratory birds’ journeys are becoming increasingly dangerous. Read our recent blog post to learn more about light pollution and how to mitigate its effects on local wildlife.

When artificial lights from nearby cities enter the night sky, migrating birds can become distracted and veer off course into threatening territory. When distracted by light pollution, birds become more likely to land in dangerous areas, where they are prone to collisions and vulnerable to unfamiliar predators.

One of the biggest dangers presented to birds drawn into urban areas impacted by light pollution is needlessly illuminated office buildings. According to the International Dark Sky Association, millions of birds in the United States die each year by colliding with empty office buildings and towers that are lit up at night. Additionally, light pollution impacts migration patterns, confusing and disrupting mating and feeding schedules.

All of this information paints a bleak portrait for the future of the feathered fowl who migrate across the U.S., but don’t lose hope! There are things each and every one of us can do to help local birds travel safely.

• First, turn off your lights at night. Unused lights, particular in unused office buildings, present a great danger to traveling fowl.

• Second, make the switch to shielded outdoor lighting. Outdoor lighting should be shielded and directed downward, where it can illuminate the ground rather than contaminate the night sky.

• Third, research and follow bird-safe habits that help reduce the hazards birds face during the migration process. In addition to turning lights off at night, these practices can include installing screens, decorative window film or window art to help prevent birds from hitting glass; moving feeders as close to windows as possible and bleaching bird feeders once a month; and practicing green gardening by growing native plants and avoiding insecticides.

Window decals can be added to increase visibility and reduce bird-strike.

The DZS has long been a supporter and practitioner of bird-safe initiatives. In 2017, we made it official by partnering with the Metro Detroit Nature Network, now known as SEMI Wild, which signed the Urban Conservation Treaty for Migratory Birds, designating Metro Detroit an Urban Bird Treaty area. Among other things, the treaty promotes bird conservation through Lights Out programs. Now, five years later, we are proud to promote these Lights Out programs, which encourage organizations and individuals to turn off or reduce interior and exterior lights during spring and fall migration, in honor of WMBD.

While there is much to be done to provide our feathered friends with safe travels this migration season, know that you can play a part by turning off one light at a time.

March of the Penguins: Polar Plunging Into Penguin Welfare

This month, the Detroit Zoological Society is bringing you not one, but three blog posts centered around our favorite flippered friends — the penguins who live at the Polk Penguin Conservation Center (read the first and second entry). The facility, which had been closed since 2019 due to waterproofing issues, reopened in February, and we can’t wait to share with you all the stories we have been saving over the past two and a half years.

In our final March of the Penguins entry, learn how animal care staff ensured the flock was thriving while its home was being repaired.

It has been a while since the public has been able to visit the penguins who call the Detroit Zoo home. You might have been wondering – what were the penguins doing during that time? In order to answer that question, staff and dedicated volunteers from the Center for Zoo and Aquarium Animal Welfare and Ethics (CZAAWE) spent nearly every day monitoring the penguins for the last two and half years.

Megan Jones, a research associate for CZAAWE, collects data in the Polk Penguin Conservation Center.

While repairs were being made to the Polk Penguin Conservation Center (PPCC), the penguins returned to their previous habitat, the Penguinarium. Animal care staff went above and beyond to make their extended stay in the Penguinarium more comfortable, including bringing snow into the habitat and even letting the penguins walk around Zoo grounds. The penguins’ move provided us with an interesting opportunity to monitor their transition between habitats and compare how they used their previous space compared to their new home in the PPCC.

The PPCC was designed to give the penguins more opportunities to express natural behaviors. It contains a 326,000-gallon pool, which holds 10 times more water than their previous habitat and is equipped with an adjustable wave machine for the penguins to enjoy. Additional improvements were made while the building was closed for repairs, including adding second snow machine within the habitat, more nesting areas and enhanced lighting.

One of the important roles CZAAWE plays at the Detroit Zoo is monitoring how major habitat modifications impact an animal’s welfare. The Association of Zoos and Aquariums defines animal welfare as an animal’s physical, mental and emotional state over a period of time, which is measured on a continuum from good to poor. Since we can’t ask the penguins what they think about all of the new features, we have to rely on decoding their behavior. CZAAWE staff and volunteers have conducted more than 5,000 observations in order to understand how the new habitat impacts the penguins’ welfare. During every observation, CZAAWE staff and volunteers record several indicators of welfare, including the penguins’ behavior, their location within the habitat and the features of the habitat they are using. Our hope was to see the penguins use a variety of different features and locations within the habitat in addition to engaging in the same natural behaviors as their wild counterparts.

We found preliminary results varied between each species. For example, the 25-foot-deep pool in the PPCC was successful in promoting swimming in king penguins, who swam more than 10 times more in the PPCC than in their previous habitat. The macaronis, rockhoppers and gentoos relished their new nesting sites, spending more time engaging in nest building behavior than they did in the Penguinarium. The gentoo penguins began to utilize the elevated nesting sites, a feature they did not use in their previous habitat. Additionally, the chinstraps had the opportunity to discover one of their favorite features of the new habitat – the underwater bubbles! Although we saw many positive signs from the penguins in their new home, CZAAWE’s monitoring revealed that the penguins continued to thrive during their stay in the Penguinarium. They maintained their use of the pool and engaged in a healthy variety of behaviors, which is often considered a positive indicator of welfare.

Our research also revealed some patterns regarding the location of each species within their new habitat. The PPCC is split into two sides to emulate the natural habitats of all five species that live at the Detroit Zoo. The southern rockhopper and macaroni penguins, typically found on rocky sub-Antarctic islands, are most likely to be found on the South American side of the habitat when you first walk into the building. The king penguins can be found near the snow piles on the Antarctica side of the habitat, while the gentoos tend to use all parts of the habitat. Our newest residents, the chinstrap penguins, are most likely to be found in the water. Most of the species gravitate toward areas of the habitat that are most similar to their natural habitats!With a new habitat comes new opportunities for both penguins and Detroit Zoo guests! What was once a rare opportunity to see king penguins immersed in the water is now a normal sight at the Penguin Center, and the large viewing windows now make it possible to get nose-to-beak with some of your favorite birds. We are thrilled to welcome you back to enjoy some of the positive benefits that major habitat modifications have had on the penguins at the Detroit Zoo.

March of the Penguins: A Tough Egg to Crack

This month, the Detroit Zoological Society is bringing you not one, but three blog posts centered around our favorite flippered friends — the penguins who live at the Polk Penguin Conservation Center. (read the first blog post, here) The facility, which had been closed since 2019 due to waterproofing issues, reopened in February, and we can’t wait to share with you all the stories we have been saving over the past two and a half years. 

Next in our March of the Penguins series, learn how animal care staff saved the life of a hatching macaroni penguin.

We’ve all heard stories from friends and family of difficult birthing events, sometimes resulting from a baby that is positioned incorrectly in the birth canal, often called a breech delivery. You may not realize that something similar can happen during the hatching of a bird. 

Fertilized eggs contain all of the nutrients needed to support a chick during development. As the chick grows, an air pocket forms at one end of the egg. For a chick to survive, it must be positioned so that it can push its beak into this air pocket just before it’s time to begin hatching. Some developing chicks are rotated or positioned incorrectly so that they can’t reach this air pocket – this means that the chick can only survive if given assistance. Over the years, bird and veterinary staffs have worked together to assist the hatching of several developing eggs.

Looking inside of a penguin egg.

The bird staff monitors eggs under development very meticulously. They take daily weights to ensure eggs steadily lose weight, a sign that the air pocket, (otherwise known as an air cell) is growing larger.  The staff also shines a special bright light through the eggs, a procedure called candling. Candling allows you to see an outline of the developing chick and air cell. Once incubation nears the end, radiographs can also be taken to visualize the skeleton of the chick and ensure the embryo is positioned normally.

In 2021, the Detroit Zoo had a single fertile macaroni penguin egg. On day 37 of a 37-day incubation period, radiographs were taken to see if the chick was able to hatch normally. The radiographs showed the chick was malpositioned in a way that can be fatal — the chick was rotated, and the beak would not be able to reach the air cell. We could feel the chick moving, and it seemed strong. After discussing our findings, we decided to begin the process of assisting the chick to hatch. 

Dr. Ann Duncan helping the chick hatch.

The shell was cleaned gently, and a Dremel tool was used to make a small opening. A sterile tool was then used to gradually make the opening larger until the position of the chick’s beak could be confirmed.  We then made a very small hole in the membrane overlying the chick’s beak. This allowed the chick to begin breathing air, so that it can stay strong and continue hatching. Chick embryos develop with the yolk sac outside of their abdomen, and as they near hatching, the yolk sac is gradually enveloped inside of the belly to provide nutrients for the first few days. Through the opening in the shell, we could see that the chick needed more time to absorb the yolk sac. We set the chick up in a warm, humid environment, and checked on it frequently. We also began offering one or two drops of water every few hours. 

She has arrived!

The next morning, we were very happy to see that the yolk sac had been mostly absorbed. We removed more of the shell to expose the belly, cleaned the skin over the belly and placed a suture to hold things in place. We then gently coaxed the chick out of the shell. In all, the hatching process took about 24 hours, which mimics the timeline of normal hatching. The macaroni chick is doing well, and is currently learning to swim in the Polk Penguin Conservation Center. She was named Betty and as you can see is full of character. We are very happy to have been given the opportunity to get her started on a long, healthy life.

The Heat is On

Summer is in full swing, and with it comes higher temperatures. Detroit Zoological Society staff ensure the animals who live at the Detroit Zoo and Belle Isle Nature Center are comfortable, regardless of what the thermometer says.

In some cases, this means giving animals the choice to either remain in their outdoor habitat or venture inside when temperatures soar. Think about how great you feel when you come into an air-conditioned building after spending time outside! But should they choose to remain outdoors, we ensure their habitats always incorporate multiple areas where the animals can find shade. The amount and location of the shaded areas change with the sun’s movement, and that stimulates the animals to move around in order to thermoregulate, just as they would in the wild. For example, you can often find the lions resting in the alcoves in the wall of their habitat, and built-in caves will serve a similar purpose in the soon-to-open Devereaux Tiger Forest. The pool on the polar bears’ “pack ice” side of the Arctic Ring of Life is even chilled!

For many of the animals, such as the eland, deer, ostrich and flamingos, animal care staff set up sprinklers and misters that can be moved around to create cool areas. Staff also make wallows for the rhinos, who cool down by covering themselves in mud. You may even see some animals enjoying “popsicles”, made by freezing pieces of fruit and vegetables or even fish, depending on the species. Keeping the animals both comfortable and stimulated is part of ensuring great welfare.

These practices are meant to not only keep the animals comfortable, but safe as well. Humans can suffer from serious heat-related issues, and the same is true for other animals. My dog really loves to go for long walks; however, during the summer, we make more of an effort to stay off the pavement and asphalt, and to walk in the shade whenever possible. Dogs don’t sweat to cool off like we do; they cool themselves through their foot pads and by panting, and pavement can heat up to 140 degrees when it is only 80 degrees outside. I also make sure to bring plenty of water with me for both of us!

My dog also enjoys going for car rides, but we have to remember that leaving any animal in a car that isn’t running can be very dangerous. Temperatures inside a parked car can rise very quickly, so leaving our animal companions at home in these instances is safer. It is our responsibility to keep the animals in our care safe, healthy and happy, whether they live at the Zoo or in our homes.

Fundraising Gala Highlights New Habitats that Promote Great Animal Welfare

Whenever we design and construct a new animal habitat, our focus is on ensuring it is expansive, naturalistic and meets the animals’ specific needs. These spaces should provide the animals with opportunities to do the things that are important to them – be it climbing trees, swimming, wallowing in the mud, and interacting with social partners (or avoiding social partners if that’s what they want at any given time).

Attendees of the Detroit Zoological Society’s (DZS’s) annual fundraising gala, Sunset at the Zoo, on Friday, June 7, will have the opportunity to observe two newly renovated and expanded spaces in the Detroit Zoo’s Asian Forest that succeed in doing just that.

A few months ago, red pandas Ash, Ravi and Ta-shi moved into the Holtzman Wildlife Foundation Red Panda Forest. DZS staff immediately began making observations to determine the effect of the new space on the well-being of the animals. We call this a “post-occupancy evaluation” – in this case, it consisted of behavioral observations on each individual as they explored their home. We spent eight weeks monitoring where they chose to spend their time and how their behavior varied based on a number of different factors, including noise levels and if guests were present in a new way the habitat provides. A 70-foot long canopy walkway extends through the trees of the space, allowing visitors to have a red panda’s-eye view.

 

Through these observations, we learned exactly what we hoped for – the red pandas demonstrated diverse “activity budgets”, which means they engaged in different behaviors throughout the day. We were really pleased to see that Ash and Ravi explored and scent-marked their space, both signs that it is stimulating for them. Ta-shi spent a bit more time inactive than the others, which is not surprising given that she is older.

The red pandas made use of most of their space, but did have some preferences, including spending time high up in the trees. This is a natural tendency for the species, and we were glad to see them use the elevated features. Having visitors present on the bridge did not seem to change their preferred resting locations, although Ash occasionally stayed inside the holding building when the habitat first opened. In order to allow the red pandas to acclimate to their new surroundings, we provided them with the choice to go inside their respective buildings. Enabling animals to choose where to spend their time is an important factor in ensuring positive welfare. This ability to retreat was also helpful when noise levels rose, primarily due to the construction happening at the Devereaux Tiger Forest close by. We were thrilled to see that Ash, Ravi and Ta-shi found their home to be a great place to live, letting us know that all of the planning that went into this habitat expansion was successful.

 

Our next post-occupancy evaluation will focus on the Devereaux Tiger Forest. The tiger forest will significantly increase the amount of space for tigers. Naturalistic features, including caves, trees, elevated areas, a waterfall and pool, have been incorporated in order to promote species-appropriate behaviors. We look forward to assessing how the new habitat impacts the well-being of the tigers when the habitat opens this summer.

This year’s Sunset at the Zoo celebrates the Asian Forest, which includes both the tigers’ and red pandas’ new digs. On the evening of Friday, June 7, guests will have the opportunity to explore the Holtzman Wildlife Foundation Red Panda Forest and take a sneak peek at the new Devereaux Tiger Forest. Just as the red panda habitat includes an exciting new experience for guests with the canopy walkway, the tiger habitat has a thrilling element of its own. In addition to expansive acrylic viewing windows, an SUV will be positioned half in the habitat and half out, allowing visitors to sit in the driver’s seat – and a tiger might just lounge on the hood.

Proceeds for Sunset at the Zoo benefit the Detroit Zoological Society’s mission of Celebrating and Saving Wildlife.

Sustainability is All in a Day’s Work

We all want that work/life balance, but when it comes to being green, let’s let the scale fall to the wayside. Incorporating sustainable practices into your daily life doesn’t just have to be at home – you can take these behaviors with you to the office. There are many ways to be green while on the job; here are some tips on how to reduce waste and use less energy from 9 to 5:

Green machines. Think of all the buzzing and beeping around you. It takes a lot of energy to power machines such as computers, printers and phones. Like you, computers need rest too – by powering down your devices when you leave for the night, you can save thousands of watts of energy per year. The machines inside the building aren’t the only ones that can go green. Carpooling to work helps reduce the amount of exhaust in the air. Doing so will not only benefit the environment, but it will promote team-building and reduce the amount of money spent on gas.

Paper-less is more. Going digital in the workplace has many benefits, such as saving time, money and space. Having information stored in databases rather than paper files can make it easier to search for that specific document you’re looking for. You will save money on storage space and also save time rummaging for that document you need.  If you do need to print, setting printers to copy double-sided by default will not only reduce your paper use by 50 percent, but it will also save the company money by not having to purchase paper as frequently.

Be bright about the light. Illuminating an entire office building takes a lot of energy and money. If your office uses fluorescent lights, consider replacing them with energy-efficient lights such as LEDs. And when it comes time to leave for the day, make sure to turn off the lights in your area. Motion-sensor lights can cut down the use of power if someone forgets to turn off the lights, so they don’t remain on all night when no one’s there. If you have a window in your office, consider working with just the natural light. During the warm months, instead of running the air conditioner, crack the window to let the fresh air in. Many office buildings have high levels of CO2, which contributes to high stress levels – by cracking the window you can improve air quality, as well as cut the cost of air conditioning.

Ditch the disposables. Styrofoam cups and plates are often used in staff kitchens, along with plastic silverware and other disposable utensils. Styrofoam can take 500 years to break down, and it takes up 25-30 percent of landfills. Throw out the disposables once and for all and replace them with reusable plates, silverware and mugs. You could also request that the powers-that-be invest in a water cooler for the office to fill reusable cups throughout the day instead of buying an endless supply of plastic bottles of water. It may seem expensive at first to buy reusable items, but you will see the cost difference in no time. By eliminating the need to repurchase these disposable items, you – and the company – will save your green by going green.

Energize organically. Many of us need that extra boost from coffee or tea in the morning to get our day started. Try getting that boost from fair trade and organic coffee and tea. Fair trade farms employ strategies for environmental sustainability by protecting the land and wildlife. Some of these farmers use the shade-grown method, which means coffee is grown under a canopy layer of trees, which not only preserves native trees, but also protects habitats for many endangered animals.  If workers prefer to go out for their coffee, suggest they bring a reusable mug – many places offer discounts if you do this. What better way to beat that 3 o’clock feeling than with coffee or tea that also saves you money.

Green Team. Implementing a green team in the workplace is a great way to raise awareness and brainstorm new ways to bring sustainability into the office. Work together to create a recycling program, help educate other staff members or organizational leadership and research information about energy-efficient appliances and green cleaning supplies. The Detroit Zoological Society’s (DZS’s) Green Team was founded in 2002 to help minimize our ecological footprint and to educate staff and visitors about choices that enable us to live a more Earth-friendly lifestyle. Being a part of our Green Team is voluntary; it is comprised of representatives from every DZS department who share their commitment, expertise and time to make our facilities greener places for staff, visitors, animals and the planet. The Green Team was a strong advocate for the development of our Greenprint goals and objectives and has been instrumental in carrying out these award-winning policies and procedures.

As a team, you can work together to find the best solutions for your office to lessen your impact on the environment. By being more conscientious, we can reduce the amount of waste we produce and energy we use, reuse what we can to keep unnecessary items out of landfills and recycle the items we don’t need the proper way. Doing so will help save wildlife and wild places for generations to come.
