 RAPTOR Historical photo - two vets working on animalIn the early 1970s, TRC co-founder Dr. Gary Duke, a faculty member at the University of Minnesota College of Veterinary Medicine, was conducting research on the digestive efficiency of grain-eating turkeys. Co-founder and current director Dr. Patrick Redig was a sophomore veterinary student who would later become a graduate student working with Duke on a Ph.D. in avian physiology. Four baby great horned owls changed the fate of both.

Brought to Duke by one of his veterinary students, the owls offered Duke an opportunity to expand his research to include avian meat-eaters. The soft baby owls, with their large yellow eyes, also captured his heart.

As Duke sought additional owls for his study through the Minnesota Department of Natural Resources, Redig, an avid falconer, offered to care for the resident owls as well as other birds not needed for research. Over time, he began to repair their injuries and return them to the wild. In the process, Redig pioneered the avian orthopedic and anesthetic techniques that are used by avian veterinarians today. He also began using live, non-releasable birds of prey to educate the general public about raptor behavior, habitat, and threats to their survival.

Today, the magic of raptors makes it possible for The Raptor Center’s educational programs to reach more than 200,000 annually.

The seeds of what today is known as The Raptor Center took root in 1974 in Haecker Hall, a building on the St. Paul campus of the University of Minnesota. Since then, much has been accomplished:


• 1975 TRC began receiving an annual grant of $5,000 from the U.S. Fish and Wildlife Service to support its veterinary work with endangered species such as the bald eagle and peregrine falcon.

• 1981 TRC compiled the first edition of Medical Management of Birds of Prey, which detailed the medical and surgical techniques he developed for birds of prey. Revised in 1993, the book is still considered a definitive guide to raptor medicine and surgery, and is used by avian veterinarians all over the world. Dr. Redig and TRC staff are currently working on another edition of this book.

• 1982 Pat Redig of The Raptor Center and Bud Tordoff of the University of Minnesota's Bell Museum of Natural History launched the Midwest Peregrine Falcon Restoration Project. In cooperation with the Nature Conservancy and the falconry community, Redig and Tordoff obtained peregrine chicks that were bred in captivity and released them into appropriate nesting sites on buildings, smokestacks, bridges, and cliffs. In 1981, there were two known nesting pairs of peregrine falcons on the Midwestern North American continent, southeastern Manitoba, and the Lake Superior basin of Ontario. As of August 2003, there are 144 nesting pairs in 9 Midwestern states and adjoining Canadian provinces. The peregrine falcon was removed from the endangered species list in 1999.

• 1985 TRC developed a sensitive and accurate diagnostic test for aspergillosis, the most common fatal disease of raptors.

• 1988 TRC staff and birds moved into a new, state-of-the-art facility constructed with funds donated by Don and Louise Gabbert of Minneapolis, Minn. The $2.5 million, 21,000-square-foot facility allowed TRC to further develop rehabilitation, education, research, and conservation activities. It is the only facility of its kind in the world.

• 1990 TRC established a three-year veterinary residency program in raptor medicine. It is the only such program in the world.

• 1990 The PUF Raptor Professorship endowment was established with gifts of more than $25,000 from Katherine B. Andersen, Sarah J. Andersen, Bruce C. Dayton, the Phoebe W. Haas Charitable Trust, Mardag Foundation, Solly Robins, and the Donald Weesner Estate. Original gifts totaled more than $258,000 and have grown to over $612,000.

• 1991 Lead was banned for hunting waterfowl owing to the research by Dr. Redig that showed a link between lead poisoning in eagles admitted to TRC and the ingestion of spent shot in waterfowl carcasses. The actual ban came about as a result of a lawsuit by the National Wildlife Federation for which Redig served as an advisor to the legal team.

• 1993 Redig was appointed to the California Condor Recovery Team, based out of the U.S. Fish and Wildlife Service in Sacramento, CA. In 1985, the California condor population had been reduced to 26 birds, of which only 9 remained in the wild. Birds were brought into captivity and were bred and managed by the San Diego Wild Animal Park and Los Angeles Zoo. Due to the continued impact of lead poisoning, re-entry to the wild was challenging. On April 11, 2002, for the first time in 18 years, a California condor egg laid in the wild was hatched in California's Ventura County. On November 8, 2006, The Raptor Center admitted a young, wild-hatched California condor for treatment of a wing fracture; the bird was successfully released at the Grand Canyon after treatment.

• 1993 The University of Minnesota Press published Raptor Biomedicine II, a book for which Redig was senior editor. Resulting from an international symposium held in Minneapolis in 1988, the book contained contributions from raptor veterinarians and biologists in 10 countries, from the United States to the United Arab Emirates.

• 1994 In collaboration with the Science Museum of Minnesota, The Raptor Center produced “Hunters of the Sky,” a 5,000-square-foot exhibit that provides a closer look at eagles, hawks, falcons, owls, and vultures and challenges visitors to confront their values and choices that threaten these extraordinary creatures. This award-winning project was funded through a grant from the National Science Foundation and the National Endowment for the Humanities; it toured for over 10 years before being permanently installed as an exhibit in Amarillo, TX.

• 1994 In order to support TRC's clinical work, The Raptor Rehabilitation Endowment was established with gifts in excess of $25,000 from Katherine B. Andersen, Harriet S. Lykken, and an Anonymous Donor. This endowment has grown to $955,000.

• 1995 Redig developed the tie-in fixator, a combination of internally and externally applied linked devices that stabilize fractures during healing. This device revolutionized orthopedic management of fractures in birds.

• 1995 A new field study was begun when The Raptor Center began using satellite telemetry to monitor the migratory routes, stopover sites, and wintering grounds of ospreys, bald eagles, and Swainson's hawks nesting in North America. This educational tool integrated into a classroom and Web-based environmental education program called Highway to the Tropics. This research resulted in Audubon adding several locations to its Important Bird Areas listing.

• 1996 The Raptor Center published Care and Management of Captive Raptors, a manual now used as the standard by many state and federal wildlife management agencies. In January 2003, the U.S. Fish and Wildlife Service decided that all individuals and organizations holding permits for raptors must comply with the standards specified in Care and Management. A revision of this book was published in 1997.

• 1997 Dr. Elizabeth Stone completed her residency and graduate program with Redig as her faculty advisor. Her research on reproductive behavior and endocrinology of cockatiels improved understanding of reproductive behavior and mate choice in companion birds leading to improved methods of managing behavioral problems.

• 1998 Dr. Jannette Ackermann completed her residency and graduate program under Redig’s tutelage. Her research related to surgical repair of elbow luxations in raptors led to medical and surgical protocols for effectively treating this type of injury in birds.

• 1998 Raptor Biomedicine III was published as a 10-year successor to Raptor Biomedicine II. Redig was an editor and the organizer of the symposium held in South Africa from which the papers published in this book were derived.

• 1999 The Raptor Center engaged in a study of lead poisoning in bald eagles along the Mississippi River. Redig had initiated a program of testing bald eagles for lead in 1976 such that every eagle admitted was evaluated. Over the years, the data painted a very clear picture of significant morbidity and mortality among eagles from lead poisoning, the source of which was spent ammunition in killed game and residues left in the field. The thrust of this effort was to gain a sense of the prevalence of exposure to eagles to lead at the population level. The results were astonishing — 80% of eagles trapped and assessed had elevated lead residues in their blood. This added considerable momentum to efforts that continue to this day at TRC to reduce the exposure of eagles to lead.

• 1999 A substantial gift from longtime supporters Doug and Wendy Dayton established the Patrick T. Redig Professorship in Raptor Medicine and Surgery at the University of Minnesota College of Veterinary Medicine.

• 1999 The peregrine falcon was removed from the Endangered Species List, a milestone in endangered species management success, contributed in large part by the work done by TRC and Tordoff in re-establishing the peregrine in the Midwestern states.

• 2001 Dr. Richard Jones, from Wales, completed his residency and graduate program with Redig as his faculty advisor. His graduate work focused on the development of a surgical process to perform endoscopy-guided vasectomy in immature birds. This process is now utilized in hybrid falcons to prevent reproduction and in young male cockatiels to prevent behavior problems.

• 2002 Redig received the Conservation Award from the Association of Avian Veterinarians for lifelong dedication to improving the welfare of the avian population.

• 2002 Dr. Jalila Abu, from Malaysia, completed her residency and Ph.D; Redig served as her faculty advisor. Her research on the use of demineralized bone matrix in avian orthopedics has contributed to a growing body of knowledge used in both human and veterinary fracture repairs.

• 2002 West Nile virus swept across the Midwest, killing wild and captive birds in significant numbers, including many endangered birds managed in captivity. In collaboration with collaborators at the University of Georgia and Louisiana State University, Redig began an effort to test and license a recombinant-DNA vaccine product developed by the Centers for Disease Control (CDC), which has already proved effective in test studies.

• 2003 Redig named chair of the Lead Mitigation subcommittee for the California Condor Recovery Team. He was invited by the U.S. Fish and Wildlife Service to head up an initiative to mitigate lead poisoning in California condors in southern California and Arizona. In addition to the California Condor Recovery Team, project partners included the California Fish and Game Department, National Rifle Association, National Shooting Sports, Safari International, and Wildlife Management Institute.

• 2003 Dr. Arnaud Van Wettere, a veterinary resident from Belgium, completed his clinical residency and graduate program. His research involved analyzing the elements and configuration of the tie-in fixator for fracture repair and optimizing the hardware used in this device.

• 2004 Dr. Miguel Sagesse, a veterinary resident from Argentina, completed his master’s thesis on West Nile virus vaccine and transfer of maternal antibody.

• 2004 The Raptor Center’s environmental education program, begun by Redig, extended its reach through a partnership with the AmeriCorps Promise Fellow program. Grants supporting two Promise Fellows allowed TRC to connect with underserved children, create a youth service-learning program and expand volunteer roles.

• 2005 Raptors in Captivity: A Guide to Care and Management, collaboratively written by TRC staff, was adopted by the US Fish and Wildlife Service as their standard on captive raptor management.

• 2006 The Raptor Center’s professional education is expanded to include raptor care professionals and veterinary technicians. Based on 30 years of experience and two books, an annual workshop on the care and management of captive raptors is begun for raptor professionals. Also, wet-lab and on-line classes for veterinary technicians in avian and wildlife medicine are begun.

• 2006 The University of Minnesota honors Redig for his pioneering work in avian orthopedics with the inclusion of the fixator that he developed on the Wall of Discovery, located along the Scholar’s Walk.

• 2007 Redig retires as Director of The Raptor Center to refocus his efforts on conservation and ecology.

• 2007 Dr. Julia Ponder named Executive Director of TRC.

• 2007 The University of Minnesota College of Veterinary Medicine presents Redig an award for excellence in service.

• 2007 The bald eagle was removed from the Endangered Species List, another milestone in endangered species management accomplished in no small part by the 30+ years of work in rehabilitation, informing of public policy, public education, and research conducted by TRC.

• 2008 The Minnesota Veterinary Medical Association awards Redig their Outstanding Faculty Award.

• 2008 Redig named Chair of Midwest Peregrine Society, responsible for continuing monitoring of the peregrine falcon population in the Midwest.
