Moving Forward with Wildlife

I am truly fascinated by the interconnectedness of our world. One of the reasons that I am so passionate about wildlife medicine and conservation is because it spans the dimensions of human, non-human animal, and environmental wellbeing. I could spend hours avidly discussing all of the intricate connections between wildlife and human health.

The COVID-19 pandemic is no exception to the fact that everything in the world is deeply intertwined. Over the last few weeks, I’ve had conversations with my friends and colleagues about issues such as social inequality, healthcare, community, societal values, epidemiology, history, new developments, and the list goes on. These recent current events also reveal an important intersection between human and wildlife health and, in doing so, provide an impetus for us to take responsibility for the wellbeing of wildlife and the environment.

There is a great deal of evidence that suggests that many emerging human diseases, including this current pandemic, are linked to our interactions with wildlife. The CDC estimates that 6 out of every 10 established infections and 3 out of every 4 new or emerging infections are from non-human animals. In addition to the current pandemic, past health crises, such as HIV and Ebola, were also linked to the wildlife trade. The goal of this article is not to thoroughly evaluate the evidence for that connection, but rather to discuss its consequences. If you would like to learn more about the relationship between wildlife and emerging human diseases, check out the resources at the end of this article.

If we acknowledge that potentially dangerous emerging diseases can often be linked to our interactions with wildlife, then we must ask — what do we do about it? For the most part, I hear two responses. One — support wildlife health and reduce harmful interactions between humans and other animals. Two — get rid of wildlife. You might guess that I would personally choose option one. I believe that every person has many reasons to do the same.

We rely on wildlife health more than we often acknowledge, or maybe would even like to admit. Wildlife health is imperative for healthy ecosystems and we rely on those ecosystems for life itself. Think big — oxygen, food security, water, climate stability, and more. Healthy ecosystems also provide enormous economic stimulation through massive industries such as transportation, shipping, recreation, and many more. We continue to uncover potential medications from areas that have persistent biodiversity, such as alternatives to opioids and possible new sources of antibiotics. We need healthy ecosystems all over the world to support and enable us to continue living on this planet. Unfortunately, those ecosystems and the inhabiting wildlife species are threatened from many directions.

Species that once had the space to exist without interacting with humans are now forced into contact with human communities after their habitats are continuously destroyed and fragmented. Climate change leads to shifting geographic ranges leading to species appearing in new locations around people that have never been exposed to them before. Many species become endangered or extinct every year, all representing possible losses for unforeseen discoveries. Devastating abuse is committed against animals through the wildlife trade all across the world. Those wildlife trade markets also pose a major risk to human health by exposing a wide variety of stressed, immunocompromised animals to each other and humans in tight quarters, sometimes being ingested and in other cases begin transported all across the world. The more we push these animals to the brink, the more at risk we become — to disease, climate instability, food insecurity, loss of biodiversity, and more.

I have good news though. Every single person has the potential to be a conservationist. That means you. Each one of us has our own unique set of perspectives and skills that can be wielded to improve the state of wildlife and ecosystem health, and therefore environmental and human wellbeing across the world. The most important thing to know is that we all have something to offer.

If you have training, consider how you might apply that knowledge to offer a new solution. Successful communication takes on infinite forms — use your method to spread awareness, organize, and build ideas together. We can communicate through visual art, music, words, writing, and so on. Find your strength and implement it. Be mindful of what you consume and purchase. Turn off your lights. If you are coming from a place of privilege, acknowledge that with a sensitive awareness and use it to make the world a better place for humans and so many other species.

No action is ‘small’. Taking action is a big and mighty step to take, no matter the scale. When you take action, you become a conservationist.

This crisis has exposed just how reliant we are on mutual compassion and consideration for other beings sharing our communities and our planet. By taking action on issues we care about, we can nourish that feeling of unity and respect. We need to nurture a culture of compassion that acknowledges the interconnectedness of all facets of our globe and daily lives. No matter how you decide to contribute to positive change in this world, you should know that it is all deeply and inevitably intertwined. An improvement on one problem supports change for another in direct and indirect ways.

While you are thinking about how you can contribute to this global kindness, don’t forget to be kind to yourself. Sometimes the constant drive to make a difference can be confusing, complicated, and filled with uncertainty. Sometimes we can inadvertently put large amounts of stress on ourselves or our relationships. Give yourself the space to constantly learn and evolve. Remember — no one is perfect and no one can do everything. We all must work together. While you are being kind to the planet and all of the creatures living on it, always remember to be kind to yourself and those around you.

I hope we learn from the solidarity that has been conjured by this pandemic. I hope we harness it for empowerment, triggering a cascade of positive actions that can change our world for the better. In my experience, taking action for the things that are important to me has been empowering. That empowerment can be a brilliant source of invigorating positive energy, particularly in times when we feel utterly powerless. When we emerge from this crisis, I hope that we can continue to unite and pursue empowerment by taking action for positive change. Let’s change the way we see and engage with each other, our world, and the other animals living within it.

Thank you for your time and thoughts. I sincerely wish health and safety to everyone reading this. I have many resources saved regarding all of the issues mentioned in this short article and I would love to share them with you if you are interested!

What Wildlife Workers Should Know About Avian Anatomy

As veterinary students, virtually all the anatomy that we learn in the core curriculum is mammalian anatomy, but most of the patients coming into the Janet Swanson Wildlife Health Center are birds.   To help fellow veterinary students and other wildlife workers, I have created this post as a brief guide to avian anatomy, focusing specifically on aspects which are directly relevant to providing routine avian care at a wildlife hospital.

Respiratory Anatomy

 

In birds, the sternum exists as a large fused structure called the keel.  Unlike mammals, birds do not have a diaphragm; during inspiration they rely on the external intercostal and levator costarum muscles which move the ribs laterally and the sternum cranio-ventrally (Figure 1).  When handling birds, it is very important not to put pressure on the keel since this prevents these movements and can potentially cause asphyxiation.  It is therefore necessary to use appropriate restraining methods that don’t place pressure on the keel (Figures 2 and 3).  During inspiration, the weight of the viscera helps to pull the sternum in the cranio-ventral direction.  However, when a bird is flipped on their back, the viscera weighs the sternum down making inspiration more difficult.  For this reason, extra caution must be taken when placing birds on their backs for long periods of time.

In the mammalian respiratory system, air enters the lungs during inspiration and exits the lungs during expiration in a bidirectional manner .  Birds instead have a unidirectional system of air flow that relies on thin-walled cavities attached to the lungs called air sacs. This allows fresh air to pass through the lungs during both inspiration and expiration (Figure 4).  The air sacs extend throughout most of a bird’s body cavity (Figure 5), covering the viscera, and even projecting into major bones.  This is important to keep in mind during subcutaneous injections, so that one does not inject into an air sac.  Pulling back on the plunger to check for negative pressure before giving a subcutaneous injection will ensure that an air sac has not been penetrated.

Figure 4: Schematic of avian respiration. (A) During inspiration, air in the trachea flows to the caudal air sacs (caudal thoracic and abdominal air sacs) while air in the lungs flows to the cranial air sacs (cranial thoracic and clavicular air sacs). (B) During expiration, the air in the caudal air sacs flows through the lungs while the air in the cranial airs sacs flows out the trachea. Credit: König et al.

Subcutaneous Injections

For birds, there are two main sites of subcutaneous injection used at the Wildlife Health Center.  The preferred site for subcutaneous fluid administration is the inguinal fold, which is located at the proximal aspect of the femur (Figure 6).  Another site used for injections in large birds is the interscapular region, which is over the back and between the shoulders.  If injecting here, it is important not to get too close to the neck, since this would risk puncturing the cervical air sac.

Gastrointestinal Anatomy

When giving food or medications to a bird by gavage  (i.e. using a tube or crop needle that goes down the throat), it is very important to place the instrument down the esophagus and not the trachea.  The esophagus in birds has a very broad opening at the back of the mouth.  In contrast, the glottis (i.e. tracheal opening) appears as a slit on the floor of the mouth just caudal to the tongue (Figure 7).  In order to avoid aspiration of fluid when giving liquid medication, the medicine should be administered where it will not enter the glottis, either behind the glottis or at the tip of the beak where it will flow to the sides of the mouth.

Unlike in mammals, the avian esophagus runs down the right side of the neck.  When inserting a tube or crop needle, correct instrument placement can be verified by palpating the instrument through the esophagus to make sure it is not in the trachea – if it is in the correct place, one should feel two tubes: the gavage tube or crop needle in the esophagus, and the trachea.  If only one tube can be felt, the instrument may be inside the trachea.  Additionally, if the instrument is placed correctly one should be able to see that the opening of the glottis is clear (Figure 8).

Some species of birds have an enlargement of the esophagus at the level of the thoracic inlet called a crop.  The crop temporarily stores ingesta before it enters the proventriculus (i.e. the glandular stomach).  When using a tube or crop needle to gavage a bird, the tip of the instrument should be all the way in the crop to avoid aspiration.  It is therefore a good idea to take note of how much length is needed to reach the thoracic inlet so that the instrument is placed far enough down the esophagus.

Anatomy of Elimination

The final part of the gastrointestinal tract in birds, the cloaca, is divided into three parts: the coprodeum, the urodeum, and the proctodeum (Figure 9).  Gastrointestinal contents enter the coprodeum from the rectum.  They then pass through the urodeum where the urinary and reproductive tracts open.  The proctodeum is the final segment of the cloaca, and it houses the copulatory organ (phallus) in males, something important to note when sexing some species of birds.

Figure 9: Anatomy of the avian cloaca. Credit: König et al.

Because the ureters open into the cloaca, birds pass their urine with their feces; this is important to note when evaluating feces and urates.  For instance, a bird with excessively watery excreta may have diarrhea or it may have polyuria.  Diarrhea would present as liquid feces while polyuria would present as an excess of liquid surrounding a relatively firm fecal mass.  One must take into account that the normal appearance of feces and urates varies significantly by species and diet (Figure 10).

Figure 10: Different images of ‘normal’ feces and urates from different types of birds. The one on the left from a pigeon is typical of granivores; the feces is firm and easily distinguished from the urates which are thick and pasty. The middle image from a great horned owl is typical of raptors which have thick or thin viscous feces mixed with urine. ‘Soft-feeders’, namely insectivores and frugivores, produce feces and urates like that presented on the right from a blue jay. The feces is thin but the color and consistency can vary greatly depending on diet. Credit: Jonathan Gorman


Integument System

The beak is covered in a hard keratinized  sheath, the rhamphotheca.  Most birds have an aggregation of sensory receptors at the tip of the beak known as the bill tip organ.  This organ is especially well-developed in ducks and geese but is absent in pigeons and sparrows.  It is important to note when working around the beak that this can be a sensitive area.

While birds do not have sweat glands, some of them do have an important gland located above the tail called the uropygial gland.  The uropygial gland produces an oily secretion which certain birds, particularly waterfowl, spread around over their feathers during preening to create a waterproof film.  This waterproof film can be degraded by urates, which is why it is important to keep housing for waterfowl clean.  This is especially important for birds that can no longer preen themselves due to injury.

Wildlife Health comes to New York City – Investigating Lead Levels in Pigeons

Wildlife in New York City. It sounds like an oxymoron, but every year, concerned New Yorkers find thousands of injured animals lying on the sidewalk. They take to Google and end up at the only wildlife rehabilitation center in NYC – the Wild Bird Fund. I was one of those people.

In 2009, two children brought a sparrow into the dog & cat clinic that I worked at. The bird wasn’t putting any weight on its right leg. After my shift was over, I made the two-hour subway ride to the Upper West Side and stepped through the front door of the Wild Bird Fund. Hens roamed freely in the lobby. A gull honked from its perch on the chair next to me. Mourning doves cooed from huge window aviaries, and a rehab worker bustled by cradling a swan, one hand supporting its long neck. I was instantly hooked. The very next week, I attended orientation to become a volunteer.

Although the Wild Bird Fund accepts all animals, more than half of its patients belong to just one species. It’s the most commonly sighted animal in New York City – the infamous pigeon, Columba livia, or, “rat with wings”.  There are over a million in NYC alone. That means thousands of sick pigeons arrive at the Wild Bird Fund every year. After volunteering for a while, I became interested in learning more about lead poisoning, one of the most common ailments among our patients.

Map of pigeon mean blood lead levels in Manhattan by zip code.

For my undergraduate senior thesis project, I decided to compile all of the blood lead levels for pigeons measured at the Wild Bird Fund from 2011 onwards. Then, I mapped these results across different neighborhoods in NYC. Sorting through and geolocating thousands of hand-written records took me the better part of an entire summer. Turns out it wasn’t in vain – I found consistently high levels of lead poisoning in small pockets of the city, areas such as Lower Manhattan and the Gowanus Canal in Brooklyn. My results also matched child lead poisoning reports published by the US Department of Health in 2010 and 2014. Sick children and sick pigeons live in the same neighborhoods.

It’s still unclear where this lead is coming from, although it’s most likely a combination of several different sources, including leaded paint, leaded gasoline, and small airplane fuel. The Wild Bird Fund data also revealed another trend: lead poisoning is significantly higher in the summer. This correlates with lead poisoning studies done on human children; Laidlaw et al. (2005) suggest that soil humidity is lower in the summer, leading to increased suspension of and exposure to lead dust.

In the end, it’s hard to look past some of the similarities between human and animal pathology, especially when we live in the same neighborhoods, breathe the same air, and eat the same food. (If you’ve never seen a pigeon chowing down on a discarded pretzel, have you truly seen New York City?) Mine is just one of many studies being published every year about human-ecosphere interaction. One emerging field involves the use of animals as bioindicators for human health. The bioindicator is the proverbial canary in the coal mine; if the wildlife falls ill, we may expect humans to fall ill as well.

Just like any other time science happens, I submitted my paper with more questions than I had answers. Wildlife is suffering, and it is by no uncertain terms our doing. It’s hard not to notice this when three of the most common problems treated at the Wild Bird Fund are lead poisoning, collision with windows, and cat attacks. Shortly after my study was published in Chemosphere, it was picked up by The New York Times and a slew of other online papers. In particular, The New York Times debated the true efficacy of predicting human disease using pigeon lives. As I read the news article, my heart sank.

I’d written a paper on pigeon health, but I was getting the impression that very few people cared if it didn’t have immediate applications to human medicine. It wasn’t entirely their fault — I had, after all, dedicated many pages of my study to drawing comparisons between pigeon and human child lead toxicity. But as accurate as these comparisons were, I’d done them in part because I hadn’t been confident that anyone would notice a study on just pigeon lead poisoning. I thought my results were important, and I wanted them to be published; writing about human medicine would help that process.

It’s not that I don’t care about human medicine — far from it. We should raise our voices, loudly and clearly, when a human is poisoned. And we should raise our voices, loudly and clearly, when an animal is poisoned as well. Lead toxicity or otherwise, it’s becoming more and more obvious that connections between human and animal health exist everywhere we turn. I guess this is a call to everyone to care just a bit more about what happens to the life that we’re surrounded by: the earthworms tunneling underfoot, the warblers migrating south, and yes, maybe that pigeon strutting past too, even if it just pooped on your windshield.

Six speakers discuss different aspects of conservation medicine at the first annual Wildlife Health Day

Dr. Elizabeth Buckles discussing the histopathology of white-nose syndrome, a fungal disease affecting North American bats.

Zack Dvornicky-Raymond DVM (’19)

On Saturday, six speakers shared their experiences in conservation, wildlife, and One Health. The topics were wide-ranging, covering conservation of endangered species, zoo animal nutrition, plastic waste, and honeybee health. For every topic, the speakers highlighted the importance of wildlife health and the role of the veterinarian.

Zack Dvornicky-Raymond (’19), kicked off Wildlife Health Day with a talk that drew from both his personal experience and his knowledge of the conservation field. Zack first described his Expanding Horizons experience in Namibia where he used his veterinary skills to help the Cheetah Conservation Fund with their guard dog breeding program. He then discussed Assisted Reproductive Technologies (ARTs) and their use in breeding endangered species, drawing from his experience studying canine reproduction at the Travis Lab. Zack also drew from his experience at the Smithsonian, where he investigated better ways to transport sperm for the endangered Przewalski’s horse, information critical for preserving the genetic diversity of the species. Zack then discussed the role of contraception-based wildlife management, before finishing off with a reflection about the impact of human population growth on the state of the natural environment.

Dr. Sara Childs-Sanford discussed the unique challenges of managing nutrition in captive wildlife. Many of the nutritional problems that zoo animals face stem from our lack of knowledge of the specific nutritional requirements for these understudied species. Dr. Childs-Sanford did leave the audience with some solutions, citing successful attempts in nutrition research: improving the reproductive success of maned wolves and helping pangolins survive in captivity.

Mariah Beck (’20)

Drawing on her research and coursework, Mariah Beck (’20) shifted the focus to environmental health with her talk on our use and waste of plastic, and its effect on ocean life. She cited three main ways that plastic waste harms marine animals: entanglement, ingestion, and toxicity. Not only do plastics harm iconic species like whales and turtles, but their toxicity also harms animals like mussels which provide important ecosystem services. Mariah called on veterinarians to advocate for reducing the amount of plastic waste in the ocean and pitched ideas to help achieve this goal.

Dr. Elizabeth Buckles dove into a case study on white-nose syndrome in bats, drawing from her own experience as a veterinary pathologist who helped identify the cause of the outbreak. This inspired several principles for working with understudied species including “know your species,” “reach out to experts,” and “be creative.” Dr. Buckles finished with several wildlife pathology anecdotes, including one about how the CDC ignored warnings from veterinarians about the arrival of West Nile Virus to the United States. These examples illustrated the need for veterinarians to speak up to protect both human and wildlife health.

The conversation moved to honeybee health when Dr. Robin Radcliffe gave a lecture on colony collapse and the light that wild honeybee colonies can shed on it. Curiously, wild honeybee populations have not suffered from all of the problems that face captive bee colonies. For instance, as Dr. Radcliffe explained, wild honeybees have developed behavioral immunity to the Varroa mite which has devastated captive bee populations. His main  message was that there is a need for greater monitoring of colony health by the veterinary community, something the Cornell College of Veterinary Medicine is facilitating by adding a new distribution course on apiary medicine.

Dr. Sharon Deem speaks at Wildlife Health Day 2018.

Dr. Sharon Deem, wildlife veterinarian for the St. Louis Zoo, finished off the day as the keynote speaker. She rehashed many of the issues brought up by other speakers, while also sharing her perspective on the most important issues in wildlife health. Dr. Deem emphasized One Health, drawing on her research on diseases of camels being used as livestock in Kenya.  She left the audience with advice for future wildlife veterinarians.

Wildlife Health day drew dozens of vet students and faculty, giving members of the Cornell Veterinary community a chance to learn about the opportunities and challenges within the field. These types of events aim to increase levels of awareness and emphasize the importance of veterinarians in conservation and One Health.

EVENT: WILDLIFE HEALTH DAY (time and location updated)

During this 1st annual event, ZAWS will be bringing a selection of diverse speakers, lecturing on topics ranging from the role of reproduction in conservation, the effects of plastic on biodiversity loss, and the importance of nutrition for wildlife conservation.

Featuring Keynote Speaker: Dr. Sharon Deem, Director of the Saint Louis Zoo Institute for Conservation Medicine

Veterinary Medicine in the Anthropocene Epoch:

The lecture will focus on the current challenges of the 21st century: minimizing the loss of biodiversity, feeding 7.6 billion people without causing too much harm to the planet, and mitigating the negative impacts of climate change on animal health. The lecture will be from the perspective of a wildlife veterinarian and her 20+ years of working on free-living wildlife health issues and with zoo collection animals at AZA accredited zoos. Dr. Deem will share stories from her work with elephants in Asia and Africa, turtle species from all over the world, and disease issues at the livestock–wildlife interface. Dr. Deem will also showcase what a veterinarian starting out can do for One Health.

Wildlife Health: new faculty to focus on Planetary Health at Cornell CVM

Image from Dr. Osofsky’s “Explaining Planetary Health” article, One-Health Cornell Blog.

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.

Please join me in welcoming:

Dr. Steven A. Osofsky, Jay Hyman Professor of Wildlife Health & Health Policy

Dr. Martin Gilbert, Senior Research Associate in Wildlife Health

Ms. Helen Lee, Wildlife Health & Health Policy – planning and operations
