Eastern Bat Acoustic Field
Techniques Workshop

Park Mammoth Resort • Park City, KY • September 8-12, 2013

The SonoBat™ 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. At the Eastern Bat Acoustic Field Techniques Workshop Joe and our staff will train students in the use of SonoBat for a variety of acoustic monitoring techniques relevant to bat inventories in eastern woodlands. Our workshop location in the rolling hills of western Kentucky includes habitat for both the Federally Endangered gray and Indiana myotis, both of which are likely to be encountered during the planned inventory activities. These inventories are becoming even more important in the wake of the rampant spread of White-nose Syndrome (WNS) among the region's bats. This workshop addresses critical bat research needs by providing intensive training in the use and implementation of SonoBat for recording bat echolocation calls and designing acoustic inventories. Participants will gain an understanding of the theory and practice of recording and analyzing ultrasonic bat vocalizations, with special emphasis on the possible pitfalls and important solutions for successful species identification.

Program Details
Our workshop location at Park Mammoth Resort (Park City KY) is an independent resort adjacent to Mammoth Cave National Park, and is situated near the transition between the famous pastoral Sinkhole Plain and the heavily forested Chester Escarpment uplands. This ecological crossroads provides roosting and foraging resources for at least twelve eastern bat species. Several nearby hibernacula have been documented as important sites for endangered Indiana and gray myotis, in addition to other hibernating bats currently at risk from WNS. The fieldwork during this course will acquaint students with critical acoustic inventory and monitoring protocols designed to study these dwindling populations.

The workshop combines indoor classroom lectures and discussions with outdoor field outings. Participants receive an introduction to the use of SonoBat software for conducing acoustic monitoring and inventories as well as a comprehensive understanding of common echolocation call characteristics used for species identification. Guided classroom demonstrations and hands-on experience with equipment in the field will acquaint participants with a full range of methods, techniques, and technologies available for acoustic analysis. 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. An annotated draft agenda is available for download here.

The SonoBat Field 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 SonoBat software. No prior experience is necessary. Students are not required to handle bats, therefore rabies pre-exposure vaccination is not required.

One session: September 8-12 (Sunday-Thursday). Class size: Limited to 20 students. Location: Park Mammoth Resort, Park City, KY.

Dates and times: September 8 (Sunday) thru September 12 (Thursday). Check-in begins at noon on September 8, at the Park Mammoth Resort conference room. The first classroom session begins promptly at 1pm. Formal presentations will conclude by noon on Thursday September 12. NOTE: Park Mammoth Resort is in the Central Time Zone.

Park Mammoth Resort Lodging:
Overnight lodging is available at the resort in the same building where lectures are scheduled. Each room has a double bed and private bath for $80.00 a night. Contact reservations at (270) 749-4101 or visit the Park Mammoth website to reserve a room during the course or for more information on resort amenities.

Off-site Lodging:
The Mammoth Cave area is rich in history as a tourist destination, as such there are numerous hotels in nearby Park City and particularly Cave City for all budgets. You can even sleep in a wigwam. We suggest Google for a list of off-site hotel locations.

General Equipment: Participants need to bring appropriate field gear, including hiking boots, a headlamp with batteries, a personal pack, and a water bottle. Participants will not handle bats at this workshop, so participants do not need rabies pre-exposure vaccination. Field locations may be cool in the fall, please bring a jacket and dress appropriately for evening activities. We will be visiting natural cave entrances, but not physically entering them, therefore WNS decontamination is not required.

Acoustic Equipment: Students should bring personal bat recording gear, laptops and connecting cables. We will have a number of full-spectrum bat detectors available including a number of Pettersson D240x and D500x detectors for participants to borrow. We will also have several Wildlife Acoustics SM2BAT+ and EM3 units available. There will be smaller numbers of Pettersson D1000x, Binary Acoustic Technology AR125 and iFR-IV models, and an Elekon Batlogger to demo. A generous, fully functional trial version of SonoBat 3 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.
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.

Eastern Bat Acoustic Field Techniques Workshop Goals

The first day has three main goals:

1. To bring everyone up to speed on the physics of sound, how bats use different call types to collect information about their surroundings, and what this means to our eventual goal of identifying bats to species based on cues we collect from echolocation calls.

2. To provide participants with a template for data-organization and file storage allowing more efficient post-processing for the remainder of the workshop.

3. To give everyone experience working with different detector models from the main manufactures, allowing participants to test-drive unfamiliar units and/or make an informed future purchase.


The second day has five goals:

1. A review of the pros, cons, and applications of HET, FD, TE, and DR detectors to collect and interpret bat echolocation calls and what this means for acoustic inventory study design.

2. A discussion of active vs. passive monitoring and how these techniques figure into an acoustic survey.

3. Addressing bat echolocation call characteristics and what is known about using these for making species ID determinations, including caveats, and confusing species.

4. A review of (or introduction to) basic SonoBat 2.9 use.

5. Assisting participants with setting up TE and DR detectors and recorders to perform PASSIVE monitoring activities.

The third day has three goals:

1. Explaining the importance of call libraries, understanding species-specific echolocation call repertoires, and the need for experience with active monitoring, call collections from known species, and time in the field with the bats and the detectors BEFORE trying to manually (or automatically) identify unknown bat calls to species.

2. Assisting participants with the different workflows for off-loading collected calls collected with different passive recording methods, before using SonoBat 2.9 to organize, group and analyze calls.

3. Introducing students to SonoBat 3.0, basic operations, and what the output means for rendering species ID decisions (i.e., dispelling the quickly emerging myth and explaining carefully that calls identified with a DP of 0.95 DOES NOT mean that there's a 95% chance that the recording was from the species indicated).

The fourth day has three main goals:

1. Continued guided hands-on experience with the software to verify species ID classifications, managing the SonoBatch data output, and vetting results of the auto-classifier.

2. Protocols for reporting on inventory and monitoring programs using acoustics, determining species occupancy, and understanding ambiguous results.

3. Steps to convert full-spectrum recordings to Zero-cross format and workflow for analysis in EchoClass and BCID software programs

The fifth day has two main goals:

1. The current and future applications of acoustic monitoring for bat surveys, new technologies on the horizon, and responsible use of automated classifiers.

2. Emphasizing responsible use of auto-classification tools for acoustic surveys and answering any lingering questions students have with the detectors, recorders, software, and/or analysis.
