Help us Protect a Billion Birds from Untimely Deaths

Every year, thousands of avid birders flock to important birding areas in the state of Michigan, hoping to see or hear a few of the millions of birds that are migrating to their breeding grounds. Birds migrate north to their breeding grounds mid-March through May; they then migrate south to their wintering grounds mid-August through October. Unfortunately, many migratory birds will meet an untimely death by colliding with glass or manmade structures, a phenomenon known as a bird collision or bird strike. It has been estimated that up to 1 billion bird-collision deaths occur every year in the U.S., according to the American Bird Conservancy. As humans continue to build structures that contain glass, the threat of bird collisions will also continue.

Birds and humans have a different visual system – we see the world differently. Glass appears invisible to birds and becomes a dangerous barrier they are unable to avoid. Oftentimes as a result, birds will fly directly into windows, causing fatal injuries. In some cases, a bird will fly away after a collision, but it will likely succumb to its injuries elsewhere.

The good news is that there are many things we can do to prevent these collisions from happening. Windows with blinds on them can be made safer to birds by keeping them partially or fully closed. Moving plants away from windows without blinds can prevent birds from thinking they can land on them. Moving bird feeders to within 3 feet of windows or more than 30 feet away from windows can prevent these collisions. There are also a variety of window films that reduce reflection on the outside of windows: ABC BirdTape can be hung vertically – 4 inches apart, or horizontally – 2 inches apart. One of the most common preventative measures people use is decals. Decals come in many shapes and forms but the most common type used is a bird silhouette decal. Companies and homeowners can also build bird-friendly buildings by incorporating reduced visibility of glass, incorporating designs in/on glass and minimizing the use of glass.

The Detroit Zoological Society believes it’s important to take care of all birds, not just those that live at the Detroit Zoo. The DZS has been committed to tracking and preventing bird collisions on Zoo grounds since 2013. All newly hired employees are required to attend orientation and learn how to recognize and report bird collisions to their supervisors. Bird department personnel have used a variety of measures including ABC BirdTape, custom CollidEscape window film and bird decals to prevent collisions. The Polk Penguin Conservation Center has specially designed “fritted” glass, and we recently incorporated custom ORNILUX Bird Protection Glass into the renovated giraffe building – this glass contains a patterned UV coating, making it visible to birds but transparent to the human eye. Detroit Zoo visitors have access to educational flyers and displays about bird collisions at various locations throughout the Zoo and ABC BirdTape is available for purchase at the Zoofari Market.

We encourage the community to take preventative measures to protect wild birds from colliding with windows in their homes, schools and businesses. Residents and property managers of high-rise buildings, apartments and condominiums can participate in the Detroit Audubon’s Project Safe Passage Great Lakes by turning off all building lights at night on unoccupied floors and spaces. Lights left on in buildings overnight are a major cause of nighttime collisions that kill millions of birds.

Porous Pavement Protects Sewer Systems

Observe storm water disappear right before your eyes through the environmentally beneficial phenomenon known as permeable pavement. Constructed of porous materials, it allows for the passage and filtration of water. While “normal” asphalt and concrete tend to be a less expensive option, permeable pavement has many benefits that help our environment, making it a better – and greener – alternative. During heavy rainfall, sewer systems tend to get overwhelmed and may result in flooding, along with basement backups and polluted waste water. To combat this, the porous material captures the runoff and filters out any pollutants. This collection of rainwater also helps to recharge groundwater and reduce surface temperatures, which is extremely beneficial to the surrounding ecosystems.

The Detroit Zoological Society (DZS) is paving the way for a more sustainable environment by utilizing this progressive green design. We first implemented permeable pavement at the Detroit Zoo in 2015 with the construction of the Cotton Family Wolf Wilderness, which features visitor walkways made with porous material. As we continue to improve the infrastructure at the Zoo, we are incorporating permeable pavement within our design plans, such as a parking lot we constructed in 2016 near the main entrance with 215 additional spaces, as well as a new visitor walkway outside the Edward Mardigian Sr. River Otter Habitat added in 2017.

Join us on our Green Journey! By implementing sustainable storm water infrastructures, we can help relieve the influx of water into the sewer system. Try disconnecting your downspouts and channel the water into your lawn or garden, plant a rain garden with native Michigan flowers and/or harvest rain water – these are all cost-effective ways you can help too.

Understanding Cardiac Health in Great Apes

Cardiovascular disease isn’t just the leading cause of death for humans, it is also a health issue faced by great apes. These majestic creatures – chimpanzees, gorillas, orangutans and bonobos – share 98 percent of human DNA. As is the case with humans, it is apparent that we need to investigate and understand the cardiac health of these animals.

Fifteen years ago, the Great Ape Heart Project (GAHP) began to form in order to address this responsibility – two zoo veterinarians, a human cardiologist and a veterinary epidemiologist put their heads together around the topic. Early on, they recognized the critical need for a multidisciplinary approach to investigate and understand cardiovascular disease in these special animals. In the years since, they have enlisted the help of a number of passionate and hard-working medical experts and scientists – the team now consists of zoo veterinarians, human and veterinary cardiologists, ultrasonographers, human and veterinary pathologists, epidemiologists, nutritionists, geneticists and zookeepers. They use clinical, pathologic and research strategies to aid in the understanding and treatment of cardiac disease in all of the ape species, with the ultimate goal of reducing mortality and improving the health and welfare of captive great apes.

Members of this project recently convened at the Detroit Zoo for what was the largest working group meeting the GAHP has held to date.

Much progress has been made over the years – with generous funding from Zoo Atlanta and the Institute of Museum and Library Services, the GAHP has been able to hire a project manager to move their initiatives forward and coordinate the development of an extensive database to store the information needed to unravel this complicated health issue. A website has been developed, containing all of the information needed for veterinarians to understand how to contribute to the project and provide feedback about their patients. Additionally, normal cardiac parameters for gorillas and chimps have been established, which is an important step toward early recognition and treatment. Human and veterinary pathologists have worked together to improve tissue collection techniques and agree upon the terminology used to discuss findings. Together, they’ve been able to identify aspects of heart disease that are shared between great apes and humans, and this has helped inform future directions for research.

This team has demonstrated that a small group of very committed people can make tremendous strides toward improving the health and well-being of animals in our care. At the Detroit Zoo, we’ve been at the forefront of research, using implantable loop recorders to understand the impact of cardiac arrhythmia on heart disease in chimpanzees and gorillas.

A thousand dollars in proceeds from our recent Pool for Primates fundraising event was donated to the GAHP by the Detroit chapter of the American Association of Zoo Keepers, Inc. The Detroit Zoological Society is committed to contributing to this important work and ensuring that great apes worldwide live longer, healthier lives.

Experience a Story of Survival

Nearly three decades ago, a tiny Tahitian land snail called the Partula nodosa was declared extinct in the wild – only 26 individual snails remained. In a final attempt to save the species from being completely wiped from the Earth, those 26 snails were sent to the Detroit Zoo as part of a cooperative breeding program.

Animal care staff worked carefully to provide the best possible living conditions for the snails while focusing on their successful reproduction, which eventually resulted in the rescue and recovery of the species. Thirty years later, there are now more than 6,000 individuals living in North American zoos, all descendants from the original group that came to the Detroit Zoo. In the last two years, 160 of these snails have been sent to Tahiti for reintroduction in the wild.

Visitors to the Detroit Zoo can become a part of this story at Shelle Isle, an exhibit in the Wildlife Interpretive Gallery that features the conservation story of these tiny mollusks. Guests are transported to the Tahitian rainforest, surrounded by tropical plants. A short video tells the snails’ story from a stable population in the first half of the 20th century to their sharp decline in the late 1970s, when an attempt to protect farmers’ crops from African land snails went awry and the Florida rosy wolf snails that were introduced to control the population preferred to eat the Partulid snails. The video also includes footage from the release of the Detroit-bred snails in Tahiti in 2015. Guests are invited to feel the shell of a giant replica of the Partula nodosa and more closely observe its structure and form. A second monitor has a live camera feed into the p. nodosa habitat in a behind-the-scenes area at the Detroit Zoo, giving guests a glimpse of the snails’ daily lives.

A favorite feature in this space is a large, “fallen” log where tiny, exact replica snails sit. Two magnifying glasses attached to the log allow visitors to get a close view of these tiny creatures. Many of them have a yellow number painted on their shell, which represents the way the snails are tagged by scientists before being released in Tahiti in order to monitor their movements and survival. The few that don’t have numbers painted on them are meant to demonstrate the successful reproduction in the wild that researchers have already observed, and the project’s continued success.

For us, an important part of this story is that it focuses not on a charismatic megavertebrate, but on a species that is not well-known, isn’t found on nursery walls or represented in the rows of stuffed animals on a toy store shelf. Conservation is not a beauty contest; all animals are important and the Detroit Zoological Society (DZS) works tirelessly to conserve species large and small – including the tiniest and slimiest of snails. By supporting the DZS, you are a critical part of this important work.

Greenprint: Hosting Eco-Friendly Celebrations

Americans amass 258 million tons of garbage annually, according to the Environmental Protection Agency. And while 35 percent of that is recycled or composted, the remaining 169 million tons of trash ends up in landfills – the breakdown of which creates toxic gases that pollute our air and water and contribute to global warming. An even more staggering statistic is that in Michigan, only 15 percent of waste produced annually is recycled – far less than the national average.

We can all take steps in our daily lives to reduce the amount of waste we are creating. At the Detroit Zoo, we no longer sell bottled water or provide plastic bags at zoo concessions. We’re converting 500 tons of animal manure annually into energy to power our animal hospital. And we are working toward a lofty goal of becoming an entirely waste-free zoo – which is not an easy task.

It’s all a part of this journey we’re on – our Green Journey – to create a more sustainable future and protect the wildlife and wild places around us. We encourage you to join us. Download our Shades of Green guide and learn what actions you can take to lighten your impact on the Earth.

With summer upon us, barbecues, picnics and pool parties are in full swing as we enjoy the beautiful weather. But oftentimes with these events, we generate a great deal of waste. Disposable paper plates and paper napkins are common, as are disposable plastic cups and cutlery. By reducing cleanup time, the event becomes easier on the host; however, the waste becomes significant. Consider holding a waste-free event and ask your guests to embrace the effort.

Here are some tips for hosting a zero-waste event:

  • Decorate with flowers and plants, which can be composted when the event is over.
  • Use cloth napkins that are easy to launder.
  • Serve food with reusable dishes and cutlery.
  • For a unique party favor, go to a second-hand store and purchase vintage-inspired plateware and encourage guests to take their plate home.
  • Forget the red solo cups; use glasses and purchase an erasable marker to write guests’ names on their glass.
  • Consider composting. If you do, be sure to educate your guests on what items can be composted before they scrape the food. Also, if they know the goal is to be waste-free, they may be more conscientious of how much food they put on their plate.
  • Get creative and have fun with it – zero-waste parties can be beautiful, along with being greener!

Portions of our annual 21-and-older fundraising gala, Sunset at the Zoo – this Friday, June 16 – are going to be waste-free. Guests will receive a commemorative glass with their champagne welcome that they can use throughout the evening as they sample drinks and dishes from more than 50 restaurants and distributors and enjoy live entertainment. Reusable bags and our Shades of Green guide will also be gifted to guests. In addition, food waste generated from the event will be composted in our anaerobic digester. This is all a part of this year’s theme of “Green is the New Black” – which celebrates our award-winning sustainability initiatives. But Sunset at the Zoo is more than just a great party – it raises funds that are critical to supporting the Detroit Zoological Society and our mission of Celebrating and Saving Wildlife.

Congress Draws Global Animal Welfare Leaders to Detroit Zoo

The 4th international animal welfare congress was held May 4-6, 2017, by the Detroit Zoological Society’s Center for Zoo Animal Welfare (CZAW), drawing leaders in the field from all over the world. Convening leaders in animal welfare is one of the Center’s primary initiatives and this was the first time we co-hosted with the World Association of Zoos and Aquariums, a global organization for leading zoos and aquariums, asked to join in our effort to move forward the welfare of animals living in the care humans. We were thrilled to combine our collective power to make a difference.

The congress brought together 140 of the world’s experts in animal welfare representing accredited zoos and aquariums, regional accrediting associations, academia and animal welfare protection organizations to discuss issues of ethics and the future of zoos and aquariums. We are committed to advancing animal welfare and although progress has been made –  both in the science and policy arenas – we must continue to face existing challenges head-on if we are to succeed. The thought-provoking conversations of this esteemed group will help to pave a path forward for zoos and aquariums around the globe.

Organizations entrusted with the care of individual animals have a unique and profound responsibility to go beyond providing good care to ensure that each individual is experiencing great welfare. Accredited zoos and aquariums are striving to raise standards of animal welfare and to ensure animals in their care are thriving. The future of zoos and aquariums depends on our ability to move forward as welfare centers, both within and beyond our walls, championing a compassionate conservation approach.

As the human footprint continues to expand and animals – both individuals and at the population level – are increasingly threatened, accredited zoos and aquariums can play a critical role in the protection and preservation of the beings with whom we share the world. The very foundation of such endeavors is a global commitment to the welfare of all animals living in the care of humans. We look forward to sharing some of the presentations from the congress on the CZAW website, and to a future in which all animals have the opportunity to thrive.

Save a Life and Find a “Fur-ever” Friend

Three weeks ago, I adopted a 7-year-old female yellow Labrador retriever from a local animal shelter. I named her Clemmie, short for Clementine. She was found as a malnourished stray with protruding ribs and visible signs indicating she’d been used to breed many litters of puppies. It’s quite possible that she was dumped when she was no longer wanted by her previous owner. While I can’t undo the things that have happened to her in the past, I will do all that I can to provide the best possible life for her going forward. As Clemmie’s newly trusted guardian, I am committed to her well-being for the remainder of her life.

In the few short weeks since she joined my family, Clemmie has brought me immense joy. She greets me with tail wags and kisses each day when I return home from work. We spend time together taking long walks, meeting neighbors and enjoying our time in nature. She’s not yet certain how to play with toys, but I’ll continue to work with her on that. I’ve purchased dog food puzzles that will provide her with mental stimulation when I have to leave her at home alone. I’m also looking into playtime opportunities at local dog parks. I’m truly grateful to have found my “fur-ever” best friend. While it might appear that I rescued her, she’s brought as much happiness into my life as I have hers.

Unfortunately, an estimated 10,000 dogs and cats are euthanized in shelters each day due to a lack of homes. That adds up to 3-4 million animals in the U. S. each year. So when you adopt an animal, not only are you bringing home a new member of your family, you’re also responsible for saving that individual’s life.

Local rescue organizations and shelters can support you in finding the perfect companion animal for you. Join us this weekend for Meet Your Best Friend at the Zoo – one of the nation’s largest off-site companion animal adoption events – where hundreds of dogs, cats, puppies and kittens are available for adoption to loving homes. And don’t forget to stop by the Zoo’s humane education table while you’re there and learn more about how we work to help people help animals.
