Event: Parrots and People in Latin America: Their Perils and Promise

Tropical Biology and Conservation invites you to an event with visiting veterinarian and conservationist Dr. LoraKim Joyner.

Parrots are the most endangered group of birds in the wild, mostly because of the illegal wildlife trade, and Central America, especially Honduras, is one of the most dangerous places for environmentalists. Despite this, conservationists in Latin America are doing amazing work preserving and cherishing their biotic communities.  Rev. Dr. LoraKim Joyner, wildlife veterinarian and Unitarian Universalist minister, works alongside these courageous people in her role as co-Director of One Earth Conservation.

Dr. Joyner will discuss the status of parrots and people in Latin America, the human dimensions that accompany parrot conservation, and what the future of conservation and research in this area requires.  She has over 30 years of front line conservation leadership in the countries of Mexico, Guatemala, Honduras, Belize, Nicaragua, Costa Rica, Panama, Guyana, and Paraguay.   She is the author of “Conservation in Time of War.”

The Elephant Diaries, Part 1: Elvina Yau (2020)

Rising second year veterinary student Elvina Yau is in Chiang Mai, Thailand, conducting research on Asian elephants.  Over the next few weeks, she will be contributing a series of posts called The Elephant Diaries about her unforgettable experience!  Check out Elvina’s personal blog at Elvina The Explorer.


My name is Elvina Yau and I am a rising 2nd year veterinary student at Cornell. While my professional interests include Companion Animal Medicine and practice ownership, I am also passionate about wildlife conservation. Expanding Horizons was an excellent opportunity to further explore this realm in an international setting.

I partnered with the Elephant Research and Education Center (EREC) at Chiang Mai University Veterinary School to conduct research on Asian elephant welfare. EREC was founded in 2010 with the objectives of conserving the Asian elephant species and preserving the elephant-based culture that Thailand embodies. According to the IUCN Red List, Asian elephants are listed as Endangered. Currently, Thailand’s remaining wild population is estimated at roughly 2,000-4,000. Without significant changes, the number of elephants may critically decline to levels beyond restorability. The country’s industrial shift from logging to tourism after the 1989 commercial forestry ban marked the rise of elephant camps. Many Asian elephants and their mahouts (caretakers designated to individual elephants) who were once employed in logging and resorted to illegal street performing now live in tourist camps as rescues. These camps enable the elephants to roam freely and interact with visitors while providing employment for their mahouts. Inevitably, the standards of care provided at these tourist camps vary. The complexity of tourist camps arises from the fact that elephant rescues are given a place to live at these sites, but tourism generates the income needed to provide sustenance and veterinary care for these elephants.

My project specifically investigates how elephant foot health is affected by housing factors, which is a reflection of the management practices at various tourist camps. Conditions such as hard flooring substrates, high workloads, or excessive feeding have been associated with the development of foot abnormalities. By performing thorough physical examinations and working directly with mahouts, I’ve been able to inspect the limbs of multiple elephants and use a foot assessment checklist to score the severity of foot pathology on the toenails, interdigital spaces, and footpads. Our team then applied this data by providing facility and husbandry recommendations that will improve elephant welfare at these camps.

Foot pathology comprises one of the most prevalent health concerns afflicting Asian elephants. Since health is a useful indicator of animal welfare, the data gathered from this study can help inform targeted management modifications that can be implemented at these camps, reducing foot disease while enhancing the welfare of these elephants. Studying the relationships between housing conditions and elephant foot health and applying those findings are tasks that involve a collaborative effort between veterinarians, mahouts, and camp managerial staff. Pursuing this international service-learning experience demonstrates the organizational and teamwork skills critical in the interrelated nature of any research and conservation endeavor.

Through Expanding Horizons, I witnessed the daily operations of elephant camps and clinics while immersing myself in the sights and sounds of Thailand. The experience dovetailed a clinical and research component that enabled me to hone my skills both as a budding clinician and inquisitive scientist. Obtaining a first-hand view of Thailand through a unique veterinary lens ultimately allowed me to delve into a new facet of my career path while assisting EREC in their efforts to champion elephant welfare.

From this experience, I wanted to gain not only clinical knowledge, but also better understand the institutional factors and management strategies that wildlife conservation hinges upon. Veterinary care is essential to maintaining the health of the elephant herd, coupled with educating the global community about these issues in order to promote conservation efforts. At Chiang Mai, I was placed in an incredible position to help provide veterinary services to and conduct research on Asian elephants—a formative and intensive experience during which I learned about the complexities and joys of caring for numerous elephants, and what advocating on their behalf truly entails.

Participating in Expanding Horizons this summer therefore provided me with a unique opportunity to broaden my perspective of conservation medicine and truly explore the versatility of a DVM degree. As I progress on my veterinary career path and continue to cultivate my professional interests, I am excited to uncover what lies ahead.

Conference: ZOOGRAPHEIN – Animals in Ancient Greece, Rome, and Beyond

The ZOOGRAPHEIN conference will be held at the ILR Conference Center and the A.D. White House.  This interdisciplinary conference reflects upon the descriptions and depictions of animals in ancient classical texts, and how these early studies contributed to zoological knowledge.

“We think this is a crucial – albeit to date understudied – aspect of the history of ancient science and of animal studies. Our keynotes consider this issue in both antiquity and the very contemporary world,” explained conference organizers Annetta Alexandridis, Associate Professor of Classics and History of Art, and Athena Kirk, Assistant Professor of Classics.

The conference is sponsored by the Departments of Classics and History of Art and Visual Studies, in collaboration with the Research Network ZOOMATHIA. It is co-sponsored by the Cornell Dairy Center of Excellence; the Archaeological Institute of America; the Departments of Philosophy, Ecology and Evolutionary Biology, and History; the Programs of Religious Studies and Feminist, Gender and Sexuality Studies; and the Cornell Institute of Archaeology and Material Studies.

Event: Monitoring Respiratory Disease in Wild Chimpanzees

Third year veterinary student Sarah Balik (2019) will present a lecture about her experience interning for the Jane Goodall Institute in Uganda through the Engaged Cornell Program this summer. Her project consisted of monitoring the health of wild chimpanzees in Kibale National Park, conducting a retrospective epidemiological analysis to understand the zoonotic potential of previous lethal respiratory disease outbreaks among the chimpanzees in Kibale, and serving the local forest adjacent communities by volunteering with a mobile medical unit to provide medical care to people who lack access to doctors. Come to this lecture to see how wildlife health, public health and One Health concepts have real world implications!

This lecture is part of the Conservation with Communities for One Health weekly lecture series. This series features veterinary students and undergraduates who traveled to Indonesia, Republic of Congo and Uganda to participated in the Engaged Cornell Program (VTMED 6743-6745 / NTRES 4150 – 4160) this summer and in preparatory coursework during the previous semester. The lectures will be every Tuesday at 4pm in LH2 during Fall semester 2017.

The Price of Freedom: How our Choice to use Lead is Killing the Bald Eagle (Part 2)

This post was originally published at Science@CornellVet on August 2, 2017 by Melissa Hanson, third year Cornell DVM student.

Last week offered a glimpse into the work the Animal Health Diagnostic Center and Wildlife Health Team has done to quantify the impact of lead on our native wildlife, but what does the story look like from the perspective of Cornell’s clinicians? Dr. Sara Childs-Sanford, a veterinarian at the Janet L. Swanson’s Wildlife Health Center, a clinical service of the Cornell University Hospital for Animals (CUHA), shared her experience treating local wildlife directly impacted by the toxic element.

“A typical patient presenting with lead toxicity is a raptor species (bird of prey) or waterfowl. These animals are weak, and often have neurologic signs and ileus (failure of food to pass through the digestive tract),” says Childs-Sanford. “Concerned members of the public usually bring the animal to CUHA after observing it unable to fly or walk.”

She explains that the primary treatment of these animals involves supportive care for dehydration and emaciation, and a blood draw to screen for serum lead values. Her team uses an in-house lead analyzer is to detect lead concentration in the blood, giving them a rapid answer regarding lead toxicity in a patient.

With the help of the analyzer, virtually every raptor or waterfowl species patient that comes through the door is screened for lead toxicity, allowing treatment to begin immediately. To target the lead, the Wildlife Health Center team uses chelation therapy, which involves the introduction of compounds that bind lead and thus allow it to be excreted by the patient. Chelation therapy is completed in five day increments for a minimum of two weeks, but many patients need to remain under the care of Childs-Sanford’s team or a wildlife rehabilitator for much longer.

What harm can a little lead do? When ingested by an animal, lead is absorbed through the blood stream where it disrupts heme synthesis, a process required for oxygen delivery. The toxin is then distributed throughout the body where it deposits in soft tissue, organs, and bone, degenerating nerves and interrupting signaling pathways necessary for neurologic and gastrointestinal function. The prognosis for patients is widely variable and dependent upon the levels of lead detected, the organ systems affected, and most importantly, how long the toxicity has been present. In general, acutely affected animals carry a better prognosis than those with chronic exposure. Unfortunately, for waterfowl and piscivorous raptors, continually eating from a contaminated body of water often results in the latter.

So, what can you do to help? For Childs-Sanford, part of the solution is clear: don’t use lead bullets or sinkers, and don’t cut fishing lines into the water. “Lead in the wild comes from people,” she stated, noting that its inexpensiveness and the lack of public awareness of its effects are likely to blame for its continued use. While the Wildlife Health Center is capable of treating animals on an individual basis, the true answer to the lead problem lies in addressing its source—us. Increased education for hunters and fishermen is vital, and eliminating the use of lead materials in our environment is the only way to save our wildlife from its devastating effects. Until then, Childs-Sanford and her team will take it one patient at a time.

The bald eagle is an American icon, a symbol of freedom, and for conservationists, one of the nation’s greatest success stories. Restored from near extinction, the species has been thriving once again—or so we thought. As it turns out, mankind may be placing unnecessary pressure on America’s best known bird.

Cornell University’s Animal Health Diagnostic Center (AHDC) employs some of the brightest minds in ecology and wildlife health. Dr. Krysten Schuler, a wildlife disease ecologist, has been leading the research effort exploring the role environmental lead plays in bald eagle health. Schuler partnered with the New York State Dept. of Environmental Conservation to analyze two decades’ worth of data collected from New York State to identify sources of mortality. Their results are disturbing: 17% of bald eagle carcasses examined revealed death due to lead poisoning, and 80% had measurable lead levels in their blood, tissues, or bone. Schuler reports that adult eagles are more likely to die from lead poisoning than juveniles, posing a serious threat to the reproductive success of the species because adults nest and rear young.

Where is all this lead coming from? A likely significant source is ammunition. Lead bullets are commonly and traditionally used for game hunting, which can leave trace levels in meat as well as in the environment. When carcasses or offal are left on the landscape, eagles will scavenge from them, consuming lead bullet fragments. Lead is toxic to all animals, including humans, and eating venison shot with lead bullets may pose a risk to consumers. Schuler explains that the bullet fragments when it hits its target, and small shards can travel more than a foot from the wound channel where they are less likely to be removed during the butchering process. Pregnant women and children are particularly sensitive to the toxic effects of lead, as developing tissues are vulnerable and easily damaged by the toxin.

So, how can we protect our families and our wildlife? Consider alternative ammunition. Modern non-lead bullets are inexpensive and do not foul firearms, as was once widely believed in the hunting community. These alternatives are safe and effective, and when combined with proper hunting etiquette, such as recovering carcasses and properly disposing of entrails, can make a real impact in the levels of lead present in the environment. Even recreational shooting with lead contaminates the environment, and participants should also consider alternatives. Lead bullets may be traditional, but they are also replaceable.

While 80% of bald eagles with measurable lead is a startling figure on its own, it is important to recognize that this species serves only as a snapshot of the entire picture. Lead is toxic to all wildlife and humans, and shared sources of food are the common denominator. “This is a problem that is both man-made and solvable,” says Schuler, emphasizing that humans have introduced lead into the environment and therefore hold the responsibility of removing it as well. Research conducted by the AHDC brings to light the severity of lead toxicity in New York State, exposing it as a true threat to wildlife health where it otherwise may have persisted as a silent killer. Schuler adds, “Just because we don’t see piles of dead eagles doesn’t mean it’s not a problem.” Thanks to her contribution, both problem and solution are now quite clear.

The CUCVM student community would like to extend a warm welcome to a number of phenomenal new hires in the wildlife health realm. Recently, the CVM has brought-on seven faculty and staff, with the goal of growing Wildlife Health / One Health / Planetary Health programs at a critical time in the College’s strategic planning.  The group strives to develop and apply science-based, multidisciplinary approaches to conservation, including through a focus on Planetary Health. In short, Planetary Health is a field focused on improving our understanding and applying appropriate metrics regarding the public health impacts of anthropogenic environmental change, so as to be able to inform decision-making in the land-use planning, environmental conservation, and public health policy realms. Planetary Health also provides a lens for the new CVM-led Master of Public Health program, with its first class starting in September of 2017. There have already been numerous excellent discussions and many new initiatives are underway, not only within the CVM, but throughout the University. Hopefully, new collaborative efforts will arise and continue to foster future discussions and cross-disciplinary action!

We look forward to the incredible things that will come from these new appointments, not only for Wildlife Health and Environmental Conservation at our University, but for conservation initiatives worldwide.

Climate change and conservation at Special Species Symposium 2017

Dr. Jan Ramer giving her keynote lecture on her work with Gorilla Doctors, conservation medicine, and One Health.

Last week, Cornell University College of Veterinary Medicine hosted the biennial Special Species Symposium.  Over 100 attendees, including veterinary students, veterinarians and vet school faculty, PhD students, and also members of the general public gathered at Cornell for a weekend of lectures and labs about the biology, medicine, and conservation of “special species.”  This year’s theme was climate change, and its impact on animal biology, life history, and survival.  The event concluded with a banquet at the Lab of Ornithology, a silent auction, and a talk by Dr. Jan Ramer.

Below is a letter written by the 2017 Special Species Symposium Coordinator, DVM/PhD student Kristina Ceres, and Registration Chair Isabel Jimenez:

The Special Species Symposium began in 1991 as the “Zoo and Wildlife Symposium” at Cornell University.  The leaders of the Cornell Zoo and Wildlife Society (ZAWS) felt there was a need to supplement the veterinary education with material related to wildlife and exotics so that graduates would be more prepared to work with those species. In second issue of the 1991 Veterinary Viewpoints newspaper, the then president of the Zoo and Wildlife Society, Dr. Karen Kearns ’93 said, “The symposium is our way of providing information that is taught in the veterinary medical curriculum. We also hope that interest in the symposium will show there is a need to increase the number of courses on wild and exotic animals offered in the curriculum”.

The SSS is a student-led and faculty-supported symposium, the goal of which is to supplement our veterinary curriculum and provide students from near and far with the opportunity to learn more about these amazing species.  Since 1991, when Dr. Kearns planned the first Special Species Symposium, the Symposium has expanded into a yearly event in partnership with the University of Pennsylvania’s College of Veterinary Medicine. Over the past 26 years, our curriculum at Cornell University has also expanded to include varied coursework and opportunities to explore wildlife, zoo and exotic medicine within the school, hospital, Wildlife Health Center, Wildlife Health Initiative, and abroad through Expanding Horizons and Engaged Cornell.

We chose climate change for the theme for the 2017 Special Species Symposium because we recognize the need for veterinarians to play an important role in helping wildlife, domestic species and humans thrive in a warming climate. Climate change affects all living creatures on Earth; from changing habitats to changing disease transmission patterns, a warming climate provides important and difficult challenges for veterinarians to tackle for years to come. Although the term has become commonplace, climate change is causing very real changes to wildlife and wild spaces, and we want to shed light on what veterinarians and wildlife biologists are doing to intervene. We hope that as the years go on, the SSS will continue to inspire students to pursue careers that involve “special species” and help participants become climate conscious veterinarians.

This symposium would not have been possible without our sponsors, speakers, lab facilitators, volunteers, the previous coordinators of the Special Species Symposium at Cornell University and the University of Pennsylvania, the Cornell Zoo and Wildlife Society executive board, and our wonderful faculty mentor, Dr. Abou-Madi. Thank you for joining us this weekend to celebrate Earth Day, conservation, and a bright future for our planet.
