Park City, Kentucky
September 4-12, 2018

Our eastern Combined Field Survey Techniques workshop is centered on the world famous karst topography of western Kentucky and Mammoth Cave National Park, providing a truly unique bat study experience.



Bats are vital components of healthy ecosystems world wide, yet they are some of the most misunderstood and difficult-to-study animals on our planet. Bat Survey Solutions and associates, have been providing bat survey services for over twenty years. Our staff will share tips and techniques for performing effective and efficient bat inventory and monitoring projects at premiere field sites throughout the country. Our eastern workshop is situated along the rolling sinkhole plains of western Kentucky and is home to both the endangered gray and Indiana myotis, providing unparalleled opportunity to work with these important animals. This workshop provides students with hands-on opportunity to investigate, handle, identify, net, trap and acoustically record an impressive diversity of bats and is ideal for wildlife biologists, environmental consultants, teachers, students, and naturalists from all backgrounds in a setting perched atop the undisputed longest and most studied cave system in the world.

Participants will also gain valuable understanding of the theory and practice of recording and analyzing bat echolocation calls, with special emphasis on the possible pitfalls and proven solutions for successful species identification. The SonoBat 4 software package, developed by Joe Szewczak (Arcata CA), is the premiere bat echolocation signal analysis package available to display, analyze, and discriminate between bat calls. During this course Joe himself, assisted by BSS staff, will train students in the use of SonoBat for a variety of acoustic monitoring techniques relevant to bat inventories across eastern habitats. These activities will provide unparalleled opportunity to collect voucher call recordings from key rare and endangered species of bats.

Our firm belief is that every capture technique and software package is biased, and researchers who rely on one tool too heavily are only offered one opinion on the species composition in their data. To this end we will be demonstrating workflow using Wildlife Acoustic's flagship bat call analysis package, Kaleidoscope Pro, with several opportunities to post process and manually vet data side-by-side with SonoBat on dual screens satisfying either workflow participants may already be invested in. The two additional zero-cross only analysis apps, BCID and EchoClass will be introduced and further demonstrated as there is participant interest. Bat Survey Solutions offeres the only workshop available that guides participants using all four North American bat call analysis workflows, compares their results, and shows how to confirm or reject the automated classifications.

Program Details
Our workshop location at Park Mammoth Resort allows us to work near two major gray bat hibernacula, and conduct fieldwork at legendary Mammoth Cave National Park. At this time of year we will have opportunity to witness the spectacular fall swarming behavior of thousands of gray myotis outside their hibernacula. We will also get to visit a protected big-eared bat roost on the Park property, which is off-limits to regular visitors. The workshop takes advantage of the remarkably accessible habitat diversity and combines indoor classroom lectures and discussions with outdoor field outings, many within walking distance of our classroom. Participants receive an introduction to the use of Kaleidoscope Pro and SonoBat software for conducing acoustic monitoring and inventories as well as a comprehensive understanding of echolocation call characteristics used for species identification in this rich habitat. Guided classroom demonstrations and hands-on experience with equipment in the field will acquaint participants with the full range of methods, techniques, and technologies available for surveying bats in almost any eastern North American habitat. See below for a complete list of lecture and discussion topics, demonstrations, and evening field activities. Daily goals and objectives for the course are described more fully at the bottom of this page. And an annotated draft agenda is available for download here.

The Eastern Combined Bat Field Survey Techniques Workshop is open to biologists and naturalists from federal, state, or local agencies, college and/or graduate students, and other professionals or enthusiasts with a desire to learn more about full-spectrum echolocation recording and bat call analysis using Kaleidoscope Pro and SonoBat software (fully functional trial copies will be available). No prior experience is necessary, however becoming familier with the software and Excel prior to class is strongly suggested. Participants will need proof of rabies pre-exposure vaccination to handle bats during this course. This is a three-shot series and students should plan to finish the series at least one month prior to attendance. Proof of sufficient rabies antibody tire (dated no more than 2 years prior to the start of the course) will also be accepted. Participants who prefer not to handle bats and who would like to focus on non-contact survey methods do not need to obtain rabies vaccinations.

Optional BCID/EchoClass Data Analysis Module
Even though the acoustic survey portions of this field workshop emphasize regional bat classifications using KaPRO and SonoBat software, during the afternoon of Day 8 we will offer an optional extension to the workshop to demonstrate workflows for processing zero-cross files in BCID and EchoClass. Instructors will guide participants on how to interpret the BCID and EchoClass automated outputs and use AnaLook and Kaleidoscope Pro to manually vet file-level classifications to confirm or reject MLE’s for species presence. Lunch on this day and an additional evening field trip or data management geek session is included. Participants must register separately for this optional Module.

More information about the Resort is available at:

Dates: September 4-12. Check-in starts at 5 PM on Day 1, class officially concludes by Day 9 at noon. Participants may register for the Day 9 afternoon Echoclass/BCID Data Module separately which extends into Wednesday night. NOTE: Park City is in the Central Time zone, so please plan your arrival accordingly as your airport may not be in the same time zone as Mammoth Cave.

Lodging: Participants are encouraged to make their own lodging arrangements, either at Park Mammoth Resort or other nearby outlets. We strongly suggest the host hotel as our agenda involves late nights and early mornings. Inexpensive chain hotels are located in Cave City and RV or tent camping is available nearby at Diamond Caverns or Mammoth Cave National Park.

Airport: The nearest major city is Nashville (airport code BNA), which is about 2 hours by vehicle and in Central Time zone (same as Park Mammoth). Louisville and Lexington are 2-3 hours away respectively in Eastern Time zone.

General Equipment: Participants need to bring appropriate field gear, including hiking boots, a headlamp with batteries, a personal pack, insect repellant, and a water bottle. Participants planning to handle bats must bring a bat handling glove, a supply of latex gloves for compliance with WNS protocols, and proof of rabies vaccination or titre. Field locations can be surprisingly cool at night, please bring a jacket and dress appropriately for evening activities. Dressing in layers is recommended due to variation between daytime high temperatures and nighttime lows during the potentially unsettled fall weather. Several capture sites require wading in almost waist-deep water, so bring clothing and footwear that can get wet to get the most from the capture aspect of this course (you will use waders if you bring them!). We will be visiting natural cave entrances, but not physically entering them, therefore WNS decontamination is not required or we will follow MACA visitor protocols. A comprehensive list suggesting a full range of items to bring to the course will be sent to all registered participants prior to the class.

Software Requirements: Functional trials of SonoBat and BCID will be available for students to install on a personal laptop prior to the course. Directions will also be provided on how to obtain the free version of Kaleidoscope and EchoClass. Please note that while frequency-division technology (a.k.a. zero-cross recordings in AnaBat format) will be demonstrated during this workshop, a comprehensive look at AnaLook and related workflow is beyond the scope of this workshop and will not be presented in detail. Microsoft Excel is required to view and compile the outputs from all the classifier programs.

If you plan to use a government/institution/corporate owned computer BE SURE you have access privileges to install software during this class. Please bring a laptop loaded with the SonoBat demo, Kaleidoscope, BCID, EchoClass (both EC and BCID will run on a Mac under Parallels), and Microsoft Excel.

It is very important for all students to pre-install all the suggested software and become familiar with basic features and operations to maximize time spent learning the various work-flows and utilities. Allow 1-3 hours to install software especially if you are new to acoustic monitoring. Participants are required to bring their own laptops with the suggested acoustic software & Microsoft Office suite, especially Excel, pre-loaded.

We will be analyzing new data as well as sample data from other previous workshops or projects. Participants are also encouraged to bring their own full spectrum data to analyze as well!

Acoustic Equipment: Students should bring personal laptops, power cables, and connecting cables. Bat detectors are not required. We will have a number of full-spectrum bat detectors available to loan to all participants, including several Pettersson D240x, D500x, and M500 detectors. Participants will not need to share equipment. We will also have Wildlife Acoustics SM3, SM2BAT+, SM4, Echometer Touch, and EM3 units available. There will be a number of Pettersson D1000x, Binary Acoustic Technology AR125, AR125FG, miniMIC, and iFR-IV models, and an Elekon Batlogger to demo. A generous, fully functional trial version of KaPRO and SonoBat 4 and SonoBat Live will be available to install on student laptops prior to the workshop. It is important to take advantage of this opportunity PRIOR to arrival to participate fully in the guided software demonstrations and post-processing of field recordings. Software download and install instructions (for MAC OSX or Microsoft Windows) will be provided to all registered participants two-weeks prior to the start of the course.

Any participants who have already invested in a detector brand or model should bring it to the class. Being familiar with the basic operation of the detector and how to connect it to a laptop and/or off-load recordings to a laptop prior to the workshop is helpful. Please bring any appropriate digital media storage devices (2GB or larger is suggested) to collect recordings and/or share data. One field trip will include a mobile (driving or walking) transect; students may use their own equipment during this exercise, and should be sure to consider power and portability issues. AnaBat users interested in the full spectrum detectors and SonoBat workflow are welcome. However, remember that SonoBat is not compatible with AnaBat recordings. AnaBat software and workflow necessitates its own dedicated workshop to cover comprehensively and therefore will not be formally covered at this workshop due to time constraints. Even participants with their own equipment may borrow workshop equipment to test side-by-side during the course.

Meals: To facilitate instruction and transitions into the field for night-time activities, all lunches and dinners during the workshop a provided, beginning with dinner on Day 2 of the course and ending with dinner on Day 7. Please indicate with your registration if you require vegetarian meals or if you have any life-threatening food allergies. Other special diets (e.g., gluten free, low fat, Paleo, etc.) are not possible. We will provide day-long coffee and tea resources. Participants are welcome to bring their own favorite or essential coffee/tea blends.

How to Register: Please order online. To register multiple people, please checkout each person individually so that we can obtain the proper contact information for each participant. Please also mention any special topics you are definitely interested in the text box provided on the checkout screen.
