Western Bat Acoustic Field
Techniques Workshop

Southwestern Research Station • Portal, AZ • May 20-24, 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 Western 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 across western habitats. Our workshop location in the heart of the Chiricahua Mountains of southeastern Arizona is at an ecological crossroads of exceptional species diversity, and bats are no exception. Twenty-one different species of bats have been documented within 5-miles of our headquarters. This workshop provides unparalleled opportunity to collect recordings from more species of bats than any other single location in the United States. 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 proven solutions for successful species identification.

Program Details
Our workshop location at the American Museum of Natural History's renowned Southwestern Research Station puts us in the heart of one of the most spectacular western wilderness habitats, yet allows us to stay and work in unexpected comfort. The Station provides three hearty prepared meals daily, climate controlled lecture rooms, and fully appointed overnight accommodations. With its location at an elevation of 5,000 feet, the Station is nestled in a lush, riparian canyon shaded by oaks, sycamores, cypress, and cottonwoods, tucked away like a pearl in an otherwise rugged and harsh landscape. Our fieldwork during this course will take us from the desert floor to high-elevation pine forest, all without having to travel more than 12 miles from the station.

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 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 acoustic analysis for almost any western 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
Western Acoustic 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, so rabies pre-exposure vaccination is not required.

One session: May 20-24 (Monday-Friday). Class size: Limited to 20 students. Location: Southwestern Research Station, Portal AZ.

Western Bat Acoustics
Field Techniques Workshop

Location and Directions: The American Museum of Natural History's Southwestern Research Station is located about 5-miles from the tiny town of Portal in southeastern Arizona, near the New Mexico border. The nearest major city is Tucson (airport code TUS), which is about 3 hours by vehicle. Participants might also find better flights and connections by flying into Phoenix (PHX) another 1-1/2 hours north of Tucson. There is no cellphone service at the Station or within the canyon at the majority of our field sites. More information about travel to the Station, is available at: http://research.amnh.org/swrs/about-swrs/directionsclimate

Dates and times: May 20 (Monday) thru May 24 (Friday). Check-in begins at noon on Monday May 20, outside the Southwestern Research Station Nature Center. The first classroom session begins promptly at 1pm. Formal presentations will conclude by noon on Friday May 24. NOTE: Arizona does not participate in daylight savings time and remains on Mountain Standard Time year round, please plan your travel to arrive in the area accordingly.

Southwestern Research Station Lodging:
Due to the remoteness of our location and paucity of nearby alternate lodging, overnight lodging is included with this workshop for the nights of 20-23 May. Lodging is dormitory style, with up to 3 people per room. A pro-rated registration fee for participants wishing to attempt to find off-site lodging is not available. While there is no cell service at SWRS, there is station-wide WiFi. that guests may use internet phone services (Skype, etc.)

General Equipment: Participants need to bring appropriate field gear, including hiking boots, a headlamp with batteries, a personal pack, sunscreen, and a water bottle. Participants will not handle bats at this workshop, so participants do not need rabies pre-exposure vaccination. Field locations can be surprisingly cool at night, 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.

Meals: All meals from Dinner on Monday May 20th to Breakfast on Friday May 24th are included with the registration fee. Please indicate with your registration if you require vegetarian meals. There is a small convenience store in Portal where food, beverages and other essentials can be purchased during limited hours.

A major component of BCM workshops is to avoid guessing games with species ID. You will be able to record real calls from expertly identified bats.

Bat Acoustics Field Techniques Workshop Goals

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.


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.
