Earlier this season, I had the incredible opportunity to attend The University of Minnesota’s 2017 Care and Management of Captive Raptors four-day comprehensive workshop from October 13-20, funded by a Philadelphia Foundation grant. With over 20 years of “talons-on” experience working with raptors in captivity, I have returned to Hawk Mountain Sanctuary from The Raptor Center (TRC) with a renewed sense of empowerment and motivation to propel our captive management practices to a world class status.

Prior to handling and training birds at the TRC, I successfully completed hands-on medical exams and necropsy under the direction of expert clinic staff. Although far from being Dr. Dolittle, after learning the best practices in diets, nutrition, equipment, and raptor housing, I am eager to implement modifications to provide the highest quality of life for my feathered coworkers.

Hawk Mountain Sanctuary’s Education Department is responsible for a collection of birds that require care and maintenance 365 days a year. In my role as senior educator and lead raptor care manager, I schedule, train, and supervise volunteers ensuring best practices and the safety of volunteers and birds. With the support of my education teammates Erin Brown and Adam Carter, I created a vetting process for volunteers to ensure consistency and high standards of care. Unable to send a text message or call staff when they are ill, we are responsible for feeding, cleaning, conducting routine health checks for the birds year-round. We take this responsibility seriously 24 hours a day, 7 days a week, monitoring bird welfare through polar vortex temperatures, mosquito-breeding season, and beyond. Attending the TRC workshop fostered my deeper appreciation for the role of avian educators as ambassadors for raptor conservation.

We also manage on-going training and enrichment for both the birds and volunteers throughout their tenure, aiming to provide a stress-free environment for our avian educators throughout their lifespan. Although young at heart, several members of our avian education team are entering their “golden years” and have geriatric needs. The HMS avian educators have individual special needs in addition to the natural history requirements of each species.

In recent years, I developed a Raptor Care Advisory Committee consisting of an avian veterinarian, raptor rehabilitator, and professional bird trainer who share their unique knowledge, specialized skills, and experience to meet the needs of our captive raptor management plan. With the guidance of the International Association of Avian Trainers and Educators (IAATE), I’ve created a collection plan, training and enrichment plans, and a retirement position statement to ensure consistency and adherence to our mission of serving as a model facility.

Although the Pennsylvania Game Commission and the United States Fish and Wildlife Service require annual audits of Hawk Mountain Sanctuary’s collection of captive birds, we also undergo a yearly voluntary audit by an outside source. Most recently, my ultimate raptor conservation hero, (after Rosalie Edge, Maurice and Irma Broun, of course), Director of the International Centre for Birds of Prey, Jemima Parry-Jones conducted a thorough exam of all birds and an audit of our enclosures and indoor raptor care facilities.  

I owe a debt of gratitude to Hawk Mountain Sanctuary’s team of volunteers, advisors, staff, and mentors who continue to support me.  When you visit the Sanctuary and enjoy a live raptor program, ‘Raptors Up Close’ or meet one of our ambassadors at a festival or large event, please know that your support makes a positive impact!

One-Health on the Horizon

Hawk Mountain Sanctuary, known worldwide for its revolutionary work on raptor conservation, also uses living education raptors to help inspire and teach others about birds of prey. If you’ve ever wondered how important the jobs of the birds that live at Hawk Mountain Sanctuary are, the answer is as easy as watching the countenance of a young audience when one of our educators introduce our “feathered co-workers.” The majestic animals captivate pupils of all ages and provide that essential connection between the wilderness of the outdoors and our own humanity. This connection is sometimes grievously missing from the current discussions surrounding climate change and public health, and the world is in need of people who can restore it.

The education raptors at Hawk Mountain were once wild birds that were severely injured and rehabilitated at a wildlife rehab center – given a second chance at life. In most cases, wildlife rehab centers are able to release the birds after they are sufficiently functional, however, there are some cases where raptors are deemed unreleasable. This is how education raptors come to be.

The question is, who is responsible for diagnosing, treating, and prescribing medicine to the injured animals both while they are in rehabilitation or while they remain in captivity to be used for education animals? I don’t think many people realize that veterinarians specializing in exotics and wildlife are needed to help care for animals like these and others in captivity all over the world.

The truth is, veterinarians specializing in treating animals other than the traditionally domesticated are vital to conservation efforts worldwide. Not only do wildlife veterinarians work to conserve global biodiversity through the lenses of medicine and animal health, but they also help contribute positively to the one health initiative that many conservation scientists have taken. This initiative usually is defined by understanding the inextricable connection between human health and animal health which hangs in a delicate balance. The spread of disease, environmental toxicity, and even natural disasters are some examples of this connection.

During my time as an education intern at Hawk Mountain Sanctuary, I was able to achieve a clear vision of my future as a wildlife and exotic veterinarian. Hawk Mountain provided me with the chance to watch this career in action, and I made connections with professionals in the field that I will be able to continually draw from for the rest of my career. I had the opportunity to watch a wildlife veterinarian examine and vaccinate all four of the sanctuary’s education raptors. Hawk Mountain’s veterinarian, Dr. Susan Pello, welcomed me to her clinic again soon afterwards where I watched her diagnose and treat an eastern screech owl with a severe eye infection.

Dr. Pello and many other wildlife veterinarians work both at a traditional veterinary clinic and with potential wildlife cases. The future prospects of this career pathway is broadening as we enter an age in which humans are having increasing impact on the general environment and global biodiversity. As people realize that protecting wildlife is a social responsibility both locally and globally, veterinarians will need to step up and offer their specific medical expertise.

When I attended the Jemima Parry-Jones vulture conservation lecture in early September, I found that veterinarians with experience in raptor medicine, nutrition, and captive breeding are desperately needed globally. In Southeast Asia, vultures are commonly poisoned by diclofenac-NSAIDS given to cattle, and their populations are declining rapidly. Electrocution and collision with poerlines are other causes of injury. The ecological role of vultures in such an environment is imperatively bound to the health and wellbeing of the humans that share the land. Vultures are a natural management system for carcasses that can become vectors for disease, bacteria, and other harmful or even deadly microorganisms. As animals continue to die from the shocking changes in climate and weather on a global scale, the ecological need for vultures could potentially increase where we are instead seeing degradation in natural populations.

In captive breeding efforts, veterinarians trained to recognize the health of both the young and adults are needed in order for there to be successful results. Many of the offspring produced in the captive breeding programs suffer from vitamin deficiencies resulting in a dire need for individuals who are well-versed in raptor nutrition and health.

Although this branch of veterinary medicine is still in the midst of developing, it is easy to predict where its future is heading. Not only can veterinarians help animals in the field for ecological and biological research, but they can also aid in the overwhelming need for general education that we hope will create the behavioral changes necessary to minimize the negative impacts of human beings on natural populations of animals such as birds of prey.

I am a firm believer that getting the opportunity to connect with an animal face-to-face can affect your own personal daily decisions that make an environmental difference when broadened in the lens of the over-all human population. Many of the potential solutions to issues in conservation come from a pool that reaches many different bodies of expertise. We cannot simply expect our problems to be solved without the contribution of the knowledgeable and their efforts. Veterinary medicine is just one facet to the mosaic of the one-health initiative that ultimately aspires to nurture the ecological balance between humans and animals globally.

Annual Raptor Care & Wellness

By Susan Pello, VMD, MS
Small & Exotic Animal Veterinarian

Hawk Mountain Sanctuary currently has 4 education ambassadors. Each bird is carefully monitored and cared for by the education staff as well as trained volunteers at Hawk Mountain. Our avian education ambassadors are trained to work with the staff to educate the public, and they represent their wild counterparts as they travel near and far. However, every bird requires daily care and yearly examinations. I enjoy travelling out to Hawk Mountain every spring to see the birds. At times, the birds will travel out to me for any issues concerning to the raptor care staff.

So, how do wild raptors become education ambassadors? Due to injury, amputation, blindness or imprinting, raptors that come into a rehabilitation facility are determined to be unfit for release and in turn become captive raptors for education. The federal government mandates specific guidelines and criteria which must be met prior to releasing a bird of prey back into the wild.  In raptors 6 weeks or younger, we worry about imprinting on humans. If this occurs the animal becomes non-releasable. We see imprinting commonly in baby cranes, vultures and other avian species.

A captive raptor requires yearly exams and wellness blood work just as our companion animals. Raptors are considered wild animals, even in captivity and their care is much different from that of a dog. Birds hide illness and therefore require a physical exam and blood work yearly.  The day to day care, includes monitoring their appetite, weight and activity. When a bird is transferred to a facility, an initial physical exam, x-rays and blood work are performed. During physical examination, I will evaluate the eyes, mouth, ears, listen to the heart and respiratory system and perform a full orthopedic examination. Feather and skin condition is also evaluated.

When housed in a captive setting, especially birds with orthopedic limitations or previous fractures, raptors are prone to feather damage and foot injuries. Together with the raptor care team, I will review options to help improve feather quality, foot care and cage enrichment. At Hawk Mountain Sanctuary, a physical examination is performed, blood is drawn and xrays are recommended. It is also recommended that all captive raptors be vaccinated for West Nile Virus (WNV).  The WNV vaccine is administered once a year prior to mosquito season. This is the only recommended vaccination.

At the time of intake, all of the birds are DNA sexed and this is because our female birds require higher levels of calcium and monitoring for egg laying behavior. The birds can produce an unfertilized egg, without a male present. Currently, all of the education birds at Hawk Mountain are female, except the newest member, a red-morph eastern screech owl.

The red-morph eastern screech owl was recently adopted by Hawk Mountain for education purposes. He has a right wing injury that limits his flight, therefore he has been determined unfit for release into the wild. He received his intake examination in January 2017.  The small owl was found to be dehydrated with multiple broken tail feathers and contracture to his right wing. Despite his severe right wing damage, he is still able to fly a little. During his examination we administered his WNV vaccination and took some blood to evaluate him for any illness.

During my visit, I also had the luxury of examining my favorite great-horned owl. GHOW is at least a 17 year old female who recently started laying eggs. She also has developed some abnormal wear to her beak and receives occasional coping (beak shaping).  

I look forward to my spring visit this year when I will have the opportunity to vaccinate and examine the entire flock of avian ambassadors at Hawk Mountain.
