In response to the growing use of bat detectors as inventory and monitoring tools, training courses to design effective acoustic studies are essential. Bat Conservation and Management, Inc. and SonoBat are hosting a SonoBat Software Training Workshop at the Eisenhower Hotel and Conference Center on the south side of Gettysburg, Pennsylvania. This course highlights current acoustic analysis techniques with a focus on the use of the latest full-spectrum bat recording equipment and echolocation call analysis using the powerful SonoBat 3 software.
One Session: March 19-20 (Saturday-Sunday). Class size: Limited to 20 participants. Location: Eisenhower Hotel and Conference Center, Gettysburg, PA.
Gettysburg National Battlefield
Please note: you will find our agenda to be well packed and allow no time whatsoever to sightsee. Plan to stay an extra day before or after this workshop if you wish to explore the National Battlefield, the Eisenhower National Historic Site, or other various museums and shops.
John Chenger, president of Bat Conservation and Management, Inc. (BCM), 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.

Dates: March 19-20 (Saturday and Sunday). Check in starts at 8 AM, Acoustic Monitoring Program begins at 9 AM in the Ballroom of the Eisenhower I building.
Airport Shuttle: We will be offering a very limited airport shuttle from and to Washington-Dulles Airport (IAD). There will be one pickup Friday March 18 at approximately 6:30 PM. There will be one drop off Monday March 21 at approximately 7 AM. Contact John Chenger with your flight info and cell phone number if you wish to take advantage of this shuttle. If you find yourself "stuck" at Dulles with hours to kill, there is a free shuttle service to and from the National Air & Space Museum Udvar-Hazy Center located on the Dulles campus and is very highly recommended.
Eisenhower Hotel Lodging:
General Equipment: The course is conducted entirely within a classroom setting, indoors, with free Wi-Fi Internet access. Functional trials of SonoBat will be available for students to install on a personal laptop prior to the course. Please bring a laptop loaded with the SonoBat demo, any previously recorded bat call files (*.wav format; recorded with time-expansion or direct-recording detectors), and a memory stick (2 GB or larger). It is very important for participants to pre-install the software and become familiar with its basic layout and operations to maximize time spent learning the various features and utilities. No fieldwork will be conducted during this workshop. No bats will be handled at this workshop. (Participants do not need rabies pre-exposure vaccination.)
Acoustic Equipment: Please bring personal bat detector(s), recorder(s), and connecting cables. We will have a number of Pettersson D240x detectors for participants to borrow, and a demo AR125 and SM2BAT. Simulated bat calls will be broadcast during a demonstration portion of the class, allowing students to make test-recordings using different detector models and practice off-loading, viewing, analyzing, and processing calls.
Meals: Morning coffee and working lunches on 19 and 20 are included with the registration fee. Please indicate below if you require vegetarian meals. All other meals are "on your own" as we expect people will want to explore some of the dinner options in historic Gettysburg nearby. Many restaurant options are available within 10 minutes of the Eisenhower Hotel, but be aware while the Eisenhower has a restaurant and lounge in house, there are no other establishments within walking distance.
Social: There will be an after meeting meeting in the Eisenhower Hotel lounge after the evening session March 19. Topics to be discussed do not necessarily have to include the Nyquist frequency and Moores Law, we may just want to unwind.
