Janet Debelak Tyburec
B.A. (English and Biology, 1989) Trinity University, started her career with bats as a full-time employee at Bat Conservation International, Inc. (BCI) in Austin TX, and she has been involved in the development of bat study field workshops since. Extensively trained by BCI Founder, Merlin D. Tuttle, Janet has personally taught more than 2,700 wildlife biologists, land managers, and students while presenting over 150 training workshops. Since 2002 she has been a private and government contractor, overseeing all training and instruction at BCI’s Arizona, California, Kentucky, and Pennsylvania locations until 2012. She has also worked with agencies, including the USDA Forest Service, USDI National Park Service, Bureau of Land Management, and the Department of Defense to conduct custom training workshops for directors, staff, seasonal employees, and volunteers. She has taught in 23 U.S. states and seven foreign countries. She currently lives and works out the Bat Survey Solutions, LLC office in Tucson AZ.
John David Chenger
President of Bat Conservation and Management, Inc. (BCM), John has worked with the Pennsylvania Game Commission (PGC) to conduct cave and mine assessments and other bat inventories. He has also worked with BCI since 1997 to facilitate training workshops in Arizona, California, Kentucky, and Pennsylvania. He founded BCM in 1999 to address nuisance bat management issues by providing man-made roosts and performing bat-exclusion and bat-proofing services. His company has grown to include seasonal bat roost and habitat surveys, U.S. Fish and Wildlife Service (USF&WS) endangered species compliance inventories, acoustic monitoring studies, and large-scale migratory bat radio-tracking projects. His work has led him to develop and manufacture commercially available survey gear including mist net poles, portable triple-high mist-net sets, harp traps, and bat houses certified by BCI. John specializes in all manner of audio, radio-tracking, and visual recording technology to study and survey bats. Using many different acoustic monitoring platforms to try and answer hard agency questions has given John a unique perspective on the ethics surrounding the responsible use of these tools, and the realization they sometimes cannot answer all the questions we ask of them. He currently lives and works out of the BCM office in Carlisle, PA.
Joseph M. Szewczak
B.S.E. (1980) Duke University, Ph.D. (1991) Brown University, is a Professor of Biological Sciences at Humboldt State University in Arcata, CA, and the developer of SonoBat software to analyze and interpret bat echolocation calls. He began his work with bats investigating their physiological regulation through the differential demands of cold hibernative torpor to the intense demands of flight and high altitude. He has since applied a physiological ecology perspective to conservation and management issues of bats such as roosting, foraging, energetics, and their basic wildlife-habitat associations. He regularly teaches bat biology and acoustic monitoring field classes and workshops throughout the US and abroad. Joe began collecting full-spectrum recordings of bats more than 20 years ago with the notion that they may someday prove useful for identifying bats, and ultimately developed SonoBat to fill the gap he needed to facilitate the specialized tasks of viewing, analyzing, and comparing bat echolocation calls and sequences for non-invasive species recognition.

Nick graduated with a B.A. in English Literature from the University of Nevada-Reno in 2015. Prior to that, he worked with bats for over a decade, receiving his rabies vaccination at the age of 8. He apprenticed under his father, conducting bat research and field studies throughout the United States. After graduation he became a programmer for SonoBat, improving the efficiency of analysis and auto-classification algorithms. He is currently working on new projects for the next generation of SonoBat software, firmware, and hardware
Tim K. Snow
Terrestrial Wildlife Specialist, Arizona Game and Fish Department. Degrees: B.S. Renewable Natural Resources, University of Arizona, 1987. Tim has over 25 years specific experience with bat inventory, research, and management. He has participated and taught various bat natural history workshops including Bat Conservation International's and Bat Survey Solutions’ Arizona workshops. He is a former Chair of the Arizona Bat Resource Group (State Working Group), past Board Member of the Western Bat Working Group, and current member of the International Union for Conservation of Nature Bat Specialist Group. Tim is a Technical Science Committee member for various U.S. Fish & Wildlife Service Recovery Teams including Mount Graham red squirrel, jaguar, ocelot, and lesser long-nosed bat. When not working with bats and other wildlife, his other passions include hunting and fishing, wildlife photography, and coaching youth baseball.
Bryan conducts mist net and acoustic surveys, creates company adverts and newsletters, and provides technical support for the array of electronics offered through Bat Conservation and Management, Inc. After getting his start in the molecular biology field, Mr. Butler developed his career in wildlife biology, which has allowed him to continue to foster a lifelong love and appreciation for the outdoors. When not in the field, Bryan can be observed around BCM’s Carlisle office writing reports and coordinating permit applications, providing client support and maintaining client communication, analyzing bat calls, testing and operating acoustic equipment and software, providing troubleshooting assistance and technical support, and website development. He has also become actively involved in assisting with bat workshops, which helps to support his most enjoyable mission at BCM - relationship building and education.
Todd has been a curious observer of the natural world all his life. His interest in ecology and animal behavior led him on a career path where it’s critical to understand how animals use and interact with their environment and other wildlife species. Throughout his career Todd has worked with a number of species in the wild and in zoological institutions, where his fieldwork with animals such as the short-beaked echidna enhanced understanding and public education about these and other unusual wildlife. Todd joined BCM as a seasonal biologist in 2004 with over fifteen years of previous wildlife capture and radio telemetry experience working with a variety of bird, mammal, and reptile species. In 2010 he joined the BCM team full time as a Wildlife Biologist/Project Manager where he coordinates with clients and wildlife agencies, directs bat mist net survey and radio telemetry teams, and conducts harp trap and hibernacula surveys, habitat assessments, and report preparation. Todd also has extensive experience with acoustic bat surveys and call data analysis for federally listed Myotis species and the Florida bonneted bat. In addition to his work with bats, Todd surveys the habitat and populations of Pennsylvania’s Allegheny woodrats and northern flying squirrels.

Christopher W. Sanders
Chris graduated from Pen State University with a B.S. in Environmental Resource Management in 1994 and upon graduation began working seasonally with bats for the PA Game Commission. Seasonal wildlife work was rapidly supplemented with contract wildlife work and gate building projects at important hibernacula and Sanders Environmental was created. Chris has now been performing and leading bat survey projects, from tiny to huge, managing up to 45 employees in a year across the eastern states. Chris has taught at and wrangled bats for us at over 15 week-long workshops assisting many participants in developing their batting skills. When not batting Chris can be found on his hobby farm raising ducks, turkey and pigs or kayak-camping on remote cell-phone-service-free islands.
