Update on Maryland’s First Non-Lethal Deer Birth Control Sterilization Spaying Program!


Our Mission:


Wildlife Rescue, Inc. (formally Wild Bird Rescue, Inc.) was founded in 1994. We assist Maryland residents with wildlife emergencies, rescue and rehabilitate wildlife with the goal of release back to nature. We are dedicated to helping people find humane solutions for co-existing with wildlife. We believe there is always a humane answer to any wildlife issue.

Quality of Care and Operating Efficiency

Wildlife Rescue, Inc. has received the award known as the "Best in America" Seal. This award is extended to only 5% of the charities that participate in the Combined Federal Campaigns. We take pride in receiving this award, which is not only a reflection of the quality of care we provide but also recognition of the efficiency of our administrative and fundraising activities. This efficiency is demonstrated by the fact that more than 86 cents of every dollar donated is used directly for the animals under our care.


2013 UPDATE - 3rd Phase Completed for Maryland’s First Non-Lethal Sterilization Spaying Birth Control Project for Deer!

In February of 2013 we completed the third phase of our non-lethal deer sterilization spaying birth control project. As in 2012, only remote immobilization darting was used and we were able to perform the rapid ovariectomy procedure on nine more does. The most interesting challenge this year stemmed from the success of the project. Now for every 10 does we observed, there was only 2 who could be darted because 8 were already sterilized. So it took a little more time and patience to find a doe who had not been sterilized already.

Our ongoing success continues to confirm both a significant reduction in fawns and a stabilization of the doe population without a major influx of new deer. This also shows a lower deer population can be achieved in a humane manner without killing any deer. It is also resulting in less browsing because the does cannot get pregnant. Just like a pregnant woman eats more for her baby so does a deer. Her caloric requirements both during pregnancy and while nursing her fawn is much greater, but after she is sterilized and no longer reproducing her food consumption drops too.

This project would not be as successful if it was not for Dr. Anthony DeNicola and the donation of the volunteer veterinarians, volunteer vet techs and other local volunteers. Keith Gold, DVM provided a critical and very important component of this third phase. Under his direct supervision and guidance, we were able to both expand and continue the training of our volunteer staff to reduce the overall cost per doe. This incredible level of volunteer support has resulted in the most significant reduction of the cost per doe to date, bringing the cost down to just 40% of the first year.

A Very Special Thank You to Keith Gold, DVM and Cheryl Williams, DVM of Chadwell Animal Hospital, and Karen Burke, DVM. Chadwell Animal Hospital's vet techs Andrea Bullock, Brittany Carter, Rebecca Gaines, Melissa Goodman, Claudia Johnson, Sharon Sieck and volunteers Jean Ayers, Debbie LaTorre, Sabino Puga, Ann Selnick, Matt Matthias, and Meredith Callahan. We would also like to thank, Dave Dentry of Dentry Biomedical. We could not have done it without you!

As more and more communities throughout the United States emulate the success of our project, we are looking very forward to not only our next phase in Maryland, but the expansion of non-lethal deer projects in more and more states which will continue to prove humane solutions work if you use them!


In February of 2012 we completed the 2nd Phase for Maryland’s First Non-Lethal Deer Birth Control Sterilization Spaying Project!!

Using only remote immobilization darting this year, we were able to perform the rapid ovariectomy procedure on 17 more does. The first 14 were sterilized in just a few days and then 3 more were sterilized in an additional day that was added over a week later. This was accomplished with volunteer veterinarians, volunteer vet techs and other local volunteer assistants under the direct supervision of Dr. Anthony DeNicola and Dr. Steven Timm. An important component of this second phase was to continue the training and expansion of our volunteer staff to reduce the overall cost per doe. We are most excited about this level of volunteer support because their generosity resulted in a significant reduction of the cost per doe.

Since many of the previously sterilized does are observed daily, we have confirmed both a significant reduction in fawns and a stabilization of the doe population.

A Very Special Thank You to Keith Gold, DVM and Tamie Haskin, DVM of Chadwell Animal Hospital, Justin Milizio, DVM and Jim Cohagen, DVM. Chadwell Animal Hospital’s vet techs Ashlee Bienert, Andrea Bullock, Claudia Johnson, Stephanie Motschiedler, Nicole Ruble and volunteers, Jean Ayers, Debbie LaTorre, Sabino Puga, Matt Matthias and Melanie Moser.


In February of 2011 we were very excited to announce the first ever NON-LETHAL WHITE-TAILED DEER STERILIZATION RESEARCH PROGRAM in the history of Maryland on private land in a residential community!

Wildlife Rescue, Inc., after many years of investigation into non-lethal methods for co-existing humanely with whitetail deer, funded a research program for proving the efficacy of spaying deer – instead of killing them – that would contribute to reducing the overall deer population, especially useful for suburban areas. The procedure is actually less intrusive than when a cat or dog is spayed since only the doe’s ovaries are removed.


The Researchers:

We brought in top experts from across the United States to guarantee that this research project was conducted under the highest standard for success. Dr. Steven Timm and Dr. Anthony DeNicola, PhD of White Buffalo Inc. recently established a protocol for rapid ovariectomy using a direct surgical approach. Their work involves the combined experience of Dr. DeNicolas' team of researchers and the surgical and field experience of Dr. Timm, and established a technique to provide surgical (definitive) sterilization in a field environment. Under the guidance of Dr. Timm, local veterinarians were also taught this rapid ovariectomy procedure.


The Results:

Our original goal was to sterilize 25 does in the first year, but within days, we exceeded our own expectations. We sterilized 32 does in the first stage of this study. This will prevent the birthing of over 300 fawns during the does’ eight-year reproductive life, and thus exponentially continuing the reduction of the overall population. In the end, the cost per prevented birth demonstrates the cost effectiveness of this humane solution for deer population control!


Twenty-five percent of the does were first corralled in a capture rotunda developed by the USDA to capture and handle deer in a minimally stressing, extremely humane way, which was safe for both the deer and workers. The USDA drove it up on a trailer from Texas for this field trial. The basic design of the rotunda was developed entirely at the USDA lab in Texas. A welding instructor and students from Boerne High School designed, engineered, and constructed the trailer. As a result, the students won over $52,000 in scholarships and equipment for the school. Two of the students said that without these scholarships, they would not have been able to attend college. We discovered the rotunda was not as safe and reliable in our cold climate and we switched to remote immobilization darting techniques for the balance of the deer that were sterilized. We would like to thank the USDA for their support and participation in this project.


Our Philosophy:

As the Board of Directors of Wildlife Rescue, Inc., we are charged with a great responsibility to honor the memory of our founder Gerda Deterer. A woman who devoted her life to alleviating the suffering of wildlife. Her dream was for people to co-exist humanely with the deer and all wildlife. We would like to thank the Maryland Department Of Natural Resources for permitting this research program and helping us to honor Gerda in a way she could only dream of.


In the past, farmers would drown kittens when they were born to keep down the cat population. We no longer use such barbaric ways to control birth rates, and now spaying cats is common practice. All we want is to move forward as a modern humane society in the same way when it comes to deer and all wildlife. Because, even if something is free of cost, it does not make it right or socially acceptable to use it.


President Kennedy once said… “Change is the law of life, and those who look only to the past or present are certain to miss the future”. Wildlife Rescue, Inc believes in the near future, the citizens of Maryland in suburban residential neighborhoods where the use of weapons are both dangerous and socially unacceptable should be afforded the option to use non-lethal solutions.


By conducting this program in a residential community, we are continuing our dedication of helping wildlife and finding humane solutions for their co-existence with Maryland citizens. While staying true to our mission to help injured and orphaned wildlife, we will also continue to research and educate the public about any new non-lethal solutions that will protect our wildlife.

In Memory of Our Founder

Gerda Deterer, Founder and President of Wildlife Rescue, Inc. passed away on October 2nd, 2009 and crossed over Rainbow Bridge to be with the thousands of animals she saved and her beloved husband Wayne who co-founded Wildlife Rescue with her. For over three decades they traveled all around the state of Maryland to help citizens with wildlife that was injured, orphaned and in dire need of emergency help. She never could understand how people could love their cat or dog and then turn a blind eye when wildlife was injured and killed.

One of our volunteers wrote, “it is safe to say, you would find Mother Nature in her DNA”. Well we think it is safe to say they were working much closer together than we knew. When Gerda received the devastating news that she had cancer, she said she just wanted one more baby season to be there for the our little wildlife patients who needed her. Well, she and Mother Nature did their magic and Gerda got her one more baby season and the babies had her for one more year. She left us at a time when the calls for wildlife help will be at their lowest in the upcoming months, peaking in the spring and summer with the influx of new wildlife babies. We have moved to our new location and we will be ready just in time for the new arrivals.

Gerda had an intense desire to help wildlife in need. Our great team of volunteers and donors inspired by her 24-7 year round efforts to help wildlife, made her dream come true. There is no one person who could ever replace Gerda, these types of individuals are extremely rare. However, with the help of our incredible group of rehabilitators, our volunteers who worked closely with Gerda, and our donors who are vitally important, we are dedicated to assuring Gerda's great legacy of helping wildlife will continue. Gerda always said "The reward of being able to be there for the animals in their time of need is all the compensation I want."

Gerda was the heart of Wildlife Rescue, Inc and even though our hearts are broken right now, we will heal and carry on. Wildlife Rescue will successfully continue her great efforts as a lasting tribute to Gerda and we will continue to help the wildlife who are so dear to her and to all of us.

Gerda asked that donations be made in her memory to Wildlife Rescue, Inc., Box 330, Monkton, MD 21111 so her dream could live on.
