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.

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.

Amazon Rainforest Conservation Partnership Helps Rural Communities

In March 2020, my suitcases were packed, and a group of 40 volunteers was ready to fly down to Iquitos, Peru to deliver school supplies to remote communities along the Amazon and Napo rivers in the heart of the Amazon Rainforest. 

Three days before my flight, Peru closed its borders in an attempt to slow the spread of COVID-19.  The Peruvian school year starts in March, so schools didn’t open for months, and even then classes were hosted only virtually. This provided an opportunity for many of the students who lived in cities to attend but left behind the communities on the river, which had no devices or access to the internet. For two full years, Adopt-a-School community partners had no access to formal education. Even more devastating than the education gap, Peru holds the highest rate of COVID-19 fatalities out of any country in the world. 

This year, as I packed my bags again, I couldn’t help but wonder if we would be able to travel. With new variants being identified regularly, I was very conscious of the responsibility that comes with international travel. I needed to keep myself and  the communities we would be visiting healthy, as well as my family when I returned home. I took extra precautions, including wearing an N95 mask the entire time I was traveling through airports and on planes. As health care workers know all too well, wearing an N95 mask for 24 hours straight is challenging and not comfortable! 

When I arrived in Iquitos, I met with our partners at Conservación de la Naturaleza Amazónica del Peru AC (known as CONAPAC), the Peruvian nonprofit that facilitates the Adopt-a-School program and several other important projects in the rainforest. A small group of volunteers that had been scheduled for the 2020 trip joined us for the school supply deliveries. We reviewed our ambitious schedule of visiting nine schools each day for five straight days and packed all the school supplies onboard the cargo boat that would be traveling with us on the river. 

We traveled out to the farthest of Amazon Explorama’s lodges, Explor Napo, and settled in for the three nights we’d be staying there. On Monday morning, we packed our lunches, divided into three groups and headed out on the river. Each of the three boats had three to four  people aboard, plus the boat driver. The rides to the schools vary, from as little as 15 minutes to sometimes more than an hour. I was visiting one of the largest communities that first morning, and we spent about 45 minutes on the boat until we arrived at Urco Miraño. 

We spent several hours in the community, distributing a school supply packet to every kindergarten, elementary and high school student (more than 100 all together!), and their teachers. We also delivered supplies for the schools in general and notebooks for the community leaders. Access to quality learning materials is an equity issue. Most families living in rainforest communities don’t have easy access to cities to purchase materials, nor do they always have the financial means to do so. While the Peruvian government provides a school building and teachers, the gap in learning materials puts the remote communities at a distinct disadvantage from their peers in cities. Living in one of the world’s most biodiverse and ecologically important areas makes access to a quality education imperative to the future of the region. 

The process of traveling to communities and sharing school supplies repeated throughout the week. Toward the end of their school year (likely in September), we will reach out to all the teachers in the communities to ask what supplies they need for their classroom. That way, we can tailor the 2023 delivery to their needs. All the materials are purchased in Peru, which supports the local economy, ensures materials fit with local curriculum guidelines and drastically reduces shipping and customs fees. The supplies are purchased with donations from an international group of donors, many of whom have traveled to the rainforest previously. If you would like to support the Adopt-a-School program, ensuring access to educational opportunities in the heart of the Amazon Rainforest, please visit our website for more information.

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.

Pip Pip Hooray for a Little Piping Plover

Let’s open this blog post with a little fun. We recently held a gender reveal and Erie, the piping plover under human care at the Detroit Zoo, is a GIRL! Not only is Erie a girl, but she is also the granddaughter of the Illinois pair from Montrose Beach, Monty and Rose.

Erie’s background:

For the first time in 83 years, piping plovers were seen nesting in Ohio. Birds Nellie and Nish quickly became a famous, feathered pair when they decided to make Maumee Bay State Park their temporary home. Of note, Nish (the male) is the offspring of Monty and Rose, the infamous piping plover pair in Chicago (about whom a book was written). On July 1, all four of their eggs hatched. The chicks – Erie, Ottawa, Maumee and Kickapoo – were given some serious security detail. A large part of the beach was cordoned off until early August to protect the young birds.

People with a passion for plovers watched this Great Lakes critically endangered species closely. Black Swamp Bird Observatory volunteers and other bird watchers gathered for weeks with binoculars, cameras and notebooks. Daily updates were posted to Nellie & Nish: The Maumee Bay Piping Plovers Facebook page.

Photo taken by Plover Patrol Volunteer Ron Schramm and posted on the Nellie & Nish Facebook page.

On August 18, hearts were broken when a volunteer found Kickapoo dead. It is believed the bird was killed by another wild animal. The next day, more difficult news was shared when it was noticed in photographs that Erie had suffered an injury to her cloaca. The cloaca is the opening for a bird’s digestive, urinary and reproductive tracts. It’s used to expel feces and lay eggs. An injured cloaca could cause chronic medical problems, as well as make it difficult for Erie to lay eggs when she is nesting.

After much discussion with wildlife agencies and piping plover experts, the decision was made to capture Erie and transport her to the Toledo Zoo for treatment. During this time, siblings Ottawa and Maumee did what piping plovers do and migrated south for the winter. It is believed that had Erie left with the others, she would likely not have survived.

Photo of Erie taken by Vince Capozziello and posted on the Nellie & Nish Facebook page.

After nearly two weeks of treatment, Erie’s injury was healing well and she was returned to the beach. Everyone expected her to head south like Nellie, Nish, Ottawa and Maumee already had – but in mid-October she was still at Maumee Bay State Park.

That’s where the Detroit Zoological Society (DZS) comes in. At the U.S. Fish & Wildlife Service’s (USFWS) request, Erie was captured and transferred to the Detroit Zoo, where we are providing medical care and a private, comfortable home for her over the winter. Our experience caring for piping plover chicks as part of the federal recovery program’s salvage captive rearing program makes the DZS a perfect fit for helping Erie. Every year, piping plover eggs that are abandoned are collected, incubated and hatched on the DZS campus and chicks are later released back to various Michigan shorelines. This program has been very successful; the Great Lakes population of piping plovers has increased from 17 breeding females in 1986 to 74 breeding females in 2021.

In the last two months, we’ve been able to watch Erie’s personality really develop. She is laid back and loves all kinds of bugs! Staff at the DZS will assess Erie’s health over the winter and release her next summer with a group of captive-reared chicks. If it is believed that her injury could present risk to her, such as causing problems when she tries to lay eggs, she may be deemed non-releasable by the USFWS and we will help to find a permanent home for her in a zoo that houses piping plovers.

Learn About the Wolf-Moose Project on Isle Royal

The Detroit Zoological Society’s top-notch education staff are always hard at work creating original lessons and content for students and families in metro Detroit and beyond. DZS educational offerings teach students to have empathy for wildlife while providing science, technology, engineering and math experiences – particularly for students who are underrepresented in or lack equal access to high-quality STEM learning. In one highly-popular six-part DZS offering, students practice science from the perspective of professional conservationists researching moose and wolves on Isle Royale.

Isle Royale is part of an archipelago in Lake Superior, an island ecosystem that supports plant and animal life through harsh winters and mild summers. It is also home to the longest-running research project dedicated to a predator-prey relationship in the world. Called the Wolf-Moose Project, the study has documented and analyzed the moose and wolf populations living on the island since 1958, investigating the complex and dynamic relationships between predators and prey while considering humans’ role in the changing ecosystem. 

The Detroit Zoological Society (DZS) supports the work on Isle Royale financially and by sending staff to participate in this study through an annual Moosewatch expedition.  DZS-led Moosewatch teams spend just over a week hiking throughout the island to look for Moose that have passed away. If they find one, they will collect specific bones for the study. Analyzing the bones can provide insight into how the moose died – whether from old age, disease, lack of food or predation from wolves. This information is critical to understanding the health of the ecosystem. 

To bring this powerful story to life for school-age youth, DZS educators created a six-module course for middle and high school students. The on-demand, online learning experience addresses science, literacy and math standards through an interrupted case-study model. In this framework, course participants take on the role of a wildlife biologist who has been tasked with examining data, historical information and other evidence to make an assessment of the health of the island ecosystem.

Drawing on this information, participants make a recommendation to either continue relocating wolves from the mainland to the islands, in an attempt to slow the rapidly growing moose population, or to let the current populations remain as they are, allowing nature to take its course. The experience is designed to help participants consider the perspectives of several key stakeholders, including conservationists, research scientists and the animals themselves. 

After submitting a recommendation for wolf population management, participants can schedule a time to meet with a Detroit Zoological Society staff member, who can answer questions, provide information about the wolves who live at the Detroit Zoo, and share stories about our conservation work. Several staff have participated in the annual Moosewatch program on Isle Royale and can provide first-hand accounts of the island. There is a charge for this virtual meeting with DZS staff, but the rest of the course is free. 

Gray wolves and humans have a long and complicated relationship. Wolves have been portrayed as villains, both in the media and literature, for generations. The reality is that all animals have an important role in their respective ecosystems, and it is our responsibility to find ways to coexist peacefully. The study on Isle Royale has provided a tremendous amount of information that has challenged our knowledge of predator and prey relationships, and how dynamic they are. This course provides an opportunity for students to learn about these relationships on Isle Royale by making use of real data and experiences – and while building critical skills they will need as our future leaders and decision makers.

Launch the course.

Amphibian Breeding Season

Spring is the time of year when most amphibians in the wild are emerging from hibernation, breeding, and eventually laying eggs. This pattern also holds true for the animals at the Detroit Zoo’s National Amphibian Conservation Center (NACC). Every year in the early months of spring, the top-notch staff at the NACC facilitate hibernation, breeding and rearing for endangered amphibians from all over the world with the intention of releasing them into their respective habitats in the wild. A few of these species include Wyoming toads (Bufo baxteri), striped newts (Notophalmus perstriatus) and Puerto Rican crested toads (Peltophryne lemur). Amphibians are highly sensitive creatures who rely on the environmental conditions of their native habitats to cue their natural cycles of breeding and to maintain their overall health.  The NACC staff are experts at recreating these environmental cues.

Facilitating breeding in Wyoming toads, for example, is a complex process involving temperature changes and natural material for burrowing. The amphibian staff use a refrigerator to replicate the natural winter cool down experienced by these critically endangered creatures, and to ease them into a state of lowered activity and metabolism. The amphibians are also provided with a special mix of substrate to burrow into during this period – very similar to how Wyoming toads in the wild burrow below the frost line during the cold months.  When they warm up after this simulated winter, the toads at the NACC are ready to breed and are paired up with mates according to the recommendations of the Association of Zoos & Aquariums’ (AZA) Species Survival Plan (SSP) for Wyoming toads. An SSP is a cooperative breeding program that is overseen by AZA-accredited institutions that breed and house animal species who are endangered or threatened.

Another example of the specialized care required to breed the unique animals at the NACC is found in the reproduction patterns of striped newts. Endemic to the long leaf pine forests of Georgia and Florida, these amphibians are known to congregate and breed in temporary pools during specific times of the year when the water levels are highest.  In order to mimic these events for the striped newts at the NACC, their habitats’ water levels are lowered for a period of time – before being raised dramatically. The natural breeding cues of the striped newts are also replicated in other ways, such as changing their “photo period,” or daylight/nighttime hours, in order to simulate different seasons.  Inside the animals’ habitats, the zookeepers also place specific aquatic vegetation that the newts have been known to prefer as sites for laying eggs.

            Puerto Rican crested toads are among the many amphibians who are known to begin breeding activities during periods of heavy and sustained rainfall. Existing only in several small isolated populations within Puerto Rico, these toads emerge from hiding during seasonal rains to find a mate and reproduce.  Making use of this knowledge, the intuitive keepers at the NACC have produced a “love song mixtape” which includes the calls of male crested toads as well as the sound of heavy rainfall. While this track may not win any Grammy Awards, it serves to stimulate the crested toads into amplexus, which is an embrace used by male toads to hold onto the female and fertilize her eggs.

After countless hours of logging temperatures, researching literature and testing water quality, the real reward comes for the staff at the NACC when these fragile and endangered animals are released into the wild having received a head start towards a brighter future. This year, in the month of June, the amphibian department at the Detroit Zoo released 3,393 Puerto Rican Crested Toads, 634 Wyoming Toads and 41 Striped Newts into native habitats ranging from the dry forests of the Caribbean Islands to the plains of Wyoming. The amphibian staff take great pride in having contributed to the conservation of some of the most important animals on the planet as well as in furthering the mission of Detroit Zoological Society.

Frog-Themed Activities in Honor of World Frog Day!

Spring is finally here — and so is World Frog Day! The weather is gradually warming up and plants are bursting through the soil, preparing to dazzle us with their blooms. Spring also brings the beautiful sounds of frogs and toads calling to each other. In honor of World Frog Day, we are sharing frog-themed activities that can be done at home with minimal supplies.

PT Borneo eared frog

Frogs live on six of the Earth’s seven continents, all of them except Antarctica. They are all different colors and sizes. The largest species of frog, the goliath frog, measures 8” to 12” in length. That is about the size of a piece of copy paper!  The smallest known frog, one of the microhylid frogs, measures less than half an inch, about the width of a regular size paperclip. If you have children at home, pull out a paper clip and a piece of copy paper. Have them compare the items to objects around the house to see what is larger than the world’s largest frog and what is smaller than the world’s smallest frog. Comparing sizes of different things helps people build number sense, or an intuitive understanding of numbers, an important skill for all of us to master, especially young children.

Green Mantella - Adam Dewey

Michigan is home to 13 species of frogs and toads. It is usually easier to hear them calling or singing to each other, than it is to actually see them. That is because they are well camouflaged, meaning they blend in with their surroundings. It is important to know which species of frogs and toads live in certain areas. They are considered bioindicators, which means they are species of animals who are greatly impacted by the health of the environment. If the water, wetlands and other places they live are polluted or contaminated, they cannot survive. If their habitat is clean and healthy, many species or individuals will be living there, all calling out to each other in a beautiful chorus.

FrogWatch - Bullfrog

The Detroit Zoological Society (DZS) leads a FrogWatch Chapter (aza.org/frogwatch and detroitzoo.org/animals/frogwatch/) to train people, like you, to recognize and record frog calls around Michigan. The data that people submit helps DZS staff and researchers to analyze and better understand frog populations throughout our area and across the country.

IMG_0474

This spring, consider spending time outside in the evening to listen for frogs and toads. You can practice being a frog and toad researcher, or a citizen scientist, by learning the calls and recording information like date, temperature, weather conditions, the time you start and stop listening, and the species you hear. The Michigan Department of Natural Resources has short recordings of each species on their website to help you learn them. Practicing recording data is an important skill, especially for kids. Send your data to Rebecca Johnson (rjohnson@dzs.org) or Mike Reed (mreed@dzs.org). Next year, you can join us for training to become a certified FrogWatch participant. The earliest calling frogs will be starting soon, the wood frogs and spring peepers, so pick a night where the temperature is above 40 degrees Fahrenheit and head outside to listen!

 

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.

Notes from the Field: Eurasian Otter Conservation Continues in Armenia

The Detroit Zoological Society’s (DZS) latest wildlife conservation initiative, preserving endangered Eurasian otters, continued with an expedition to Armenia in late 2018. Their status in this country has declined dramatically in recent years while numbers have also fallen in neighboring Azerbaijan and Iran.

Our first goal of the project is to understand where the otter population currently stands throughout the regions of Armenia that contain separate river systems, which provide suitable habitats for otters. These 13 systems – called watersheds – don’t always show signs of otters inhabiting them, so the DZS is working to identify and prioritize which of those locations are best suited for the preservation of this species.

On our first expedition in June, we discovered that the otter populations the southcentral region of Armenia were significantly greater than expected. If these conclusions are accurate, it would be rare but exciting news in conservation work.

We returned in December and traveled to watershed areas in north and central Armenia to confirm the presence and relative abundance of otters in these regions During these investigations, we confirmed reports of otter conflict with humans in the area. Otters were found to be eating the trout in fish farms that would eventually be reintroduced to Lake Sevan as part of a native species restocking project.

Surveys conducted on foot of the areas near Arpi Lake National Park and Dilijan National Park showed signs of the presence of otters, including tracks, feces and other indicators such as partially eaten fish. These surveys, along with interviews with local residents, suggest that hunting by humans has also led to the decline of otters in the area.

Additionally, photographs downloaded from our trail camera along the Arpa River revealed not only otters, but illegal fishermen. Proof of this activity will help us greatly in making a case to establish a protected area. In addition to documenting illegal fishing in these areas, which depletes otter food sources, we’ve also documented illegal otter trapping efforts. We hope that if this illegal activity can be stopped, migration of otters from neighboring populations will help restore their numers in the area.

Plans for 2019 include reviewing additional trail camera images from Arpi Lake National Park, and surveying the remaining watersheds in Armenia. After completing this work, we will be able to provide a robust update on the status of otters in this country. With that information, we can continue to explore options to set up sustainable protected areas, as well as develop local education programs to enhance otter conservation in these important areas.

Creating Environmental Stewards in the Amazon

Imagine if you were a teacher and your outdoor classroom was the Amazon rainforest. Endless biodiversity of every species of plant and animal you can imagine exists just a step outside your classroom walls. However, your teacher preparation was at a university in a city, and you have no idea where to begin teaching about ecology beyond what you’ve read in a teacher prep textbook. On top of these challenges, the only way to reach the community you’ve been assigned to work in is to take a boat down the Amazon River. The trip takes several hours, which means you’re only home on weekends and rarely have an opportunity to learn with or connect to other teachers.

Such is the case for the dedicated employees of CONAPAC, the Civil Association for Conservation of the Peruvian Amazon Environment, which was formed in July 1990 by a group of teachers, forestry engineers, and employees of the travel operator Explorama Lodges in Iquitos, Peru. Registered with the Peruvian government, its purpose is the conservation of the Peruvian Amazon primary rainforest. Though the staff is small, it serves those most in need of education and other tools for sustainable living in the rainforest, with the help of Explorama Lodges. The Detroit Zoological Society (DZS) has been a partner in this important conservation and education program for nearly 20 years.

As part of the services and support CONAPAC provides partner communities, an annual teacher workshop brings educators in these rural, remote communities together to learn. Earlier this year, Karen Purcell from the Cornell Lab of Ornithology returned for the second time to provide professional development for these teachers. Fluent in Spanish and passionate about birds, she delivers dynamic, hands-on workshops that demonstrates what teachers can do with their students by having the teachers do it with her. Guides from Explorama Lodges, who are also bird experts, assisted by guiding the teachers to understand how binoculars work, how they add excitement to bird observation, and how to identify common species.

Karen created a safe place for the teachers to share their attitudes towards birds, addressing common misconceptions and dispelling myths and legends that often cause people to dislike or even dispatch birds. She prepared them to be citizen scientists, gathering and sharing data on the species they see most in theircommunities. The teachers continue to document their successes and encourage one another through a massive group chat in WhatsApp. While there may not be internet access in these communities, almost all the teachers have a cell phone that has service and a means to charge the phone by generator or solar panel collected energy. Not a week goes by without a teacher posting photos of his or her students looking for birds, drawing them, building replica nests or some other activity. Karen and the team from CONAPAC are all on the group chat, documenting the progress in real time of how the workshop content is being implemented.

In early November, DZS staff returned to the rainforest to assist with end-of-the-year evaluations in each community. Teams of CONAPAC staff, Iquitos Board of Education representatives, local environmental experts and DZS staff traveled to each community to ensure school supplies are being utilized, children and teachers are attending school regularly, and that the teachers are implementing their skills and concepts shared with them during the workshops. The artwork, poems, field work and skits that the communities shared with the teams provided solid evidence that the spring workshops were a tremendous success.

Professional development is an essential part of any profession. The CONAPAC teacher workshops are a vital part of creating the next generation of environmental stewards, providing teachers and students the information and passion needed for protecting the rainforest for generations to come. This year’s workshop was supported through the generous financial support of JBQ Charitable Foundation and Explorama Lodges.  An international donor-base further provides financial support to provide annual teacher and student school supplies.
