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 Conservation and Management, Inc. (BCM), has been providing bat survey services for over a decade. In 2014, 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 western workshop in the heart of the Chiricahua Mountains of southeastern Arizona is at an ecological crossroads of unparalleled species diversity, where bats are no exception. Twenty-one different species of bats have been documented within 5-miles of our headquarters. 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.

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 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 BCM staff, will train students in the use of SonoBat for a variety of acoustic monitoring techniques relevant to bat inventories across western habitats. These activities will provide unparalleled opportunity to collect voucher call recordings from more species of bats than any other single location in the United States.

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 arid 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 surveying bats in 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.And an annotated draft agenda is available for download here.

The Western Bat 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 SonoBat software. No prior experience is necessary. 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.

One session: 16 ­ 22 May (Friday-Thursday). Class size: Limited to 20 students. Location: Southwestern Research Station, Portal AZ.

General Equipment: Participants need to bring appropriate field gear, including hiking boots, a headlamp with batteries, a personal pack, sunscreen, bat handling glove, a supply of latex gloves for compliance with WNS protocols, and a water bottle. Participants will need proof rabies pre-exposure vaccination to handle bat during this course and should plan to obtain the three-shot series at least one month prior to attendance if needed. Proof of sufficient rabies antibody tire (dated no more than 2 years prior to the start of the course) will also be accepted. Field locations can be surprisingly cool at night, please bring a jacket and dress appropriately for evening activities. Bring clothing and footwear that can get wet. We will be visiting natural cave entrances, but not physically entering them, therefore full WNS decontamination is not required. 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.

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 3.2.0 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.

Western Bat Survey Techniques Workshop Daily Goals and Objectives

Day 4: Vetting Automated Survey Results

1. Introduce 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).

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

3. Illustrate data-collection and reporting protocols for summarizing inventory efforts.

4. Make a study design to use acoustics to sample habitats we have been unable to net and trap thus far and/or design protocols for conducting a mobile acoustic transects through our study site.

 

Day 5: Putting it All Together-Combining Survey Methods

1. Summarize previous nights' capture and acoustic inventory results, describing what we have discovered and taking bat natural history into account to modify our efforts to document additional species.

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

 

3. Discuss active vs. passive monitoring and how these techniques figure into an acoustic survey.

4. Case Studies: Species accumulation curves, combining capture and acoustic inventories to increase effectiveness and efficiency of species occupancy surveys.

5. Case Studies: Compare and contrast point-count vs. mobile bat surveys using acoustic inventory techniques.

6. Case Studies: Using acoustics to document bat activity outside roosts, tips for successful deployments, and using temporal clues to aid in occupancy determinations.

 

Day 6: Additional Survey and Analysis Tools:

1. Illustrate steps to convert full-spectrum recordings to Zero-cross format and workflow for analysis in EchoClass and BCID software programs.

2. Highlight methods for automatically analyzing echolocation recordings using SonoBat, EchoClass, BCID and/or Kaleidoscope software programs and how to compare confidence ranges.

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

4. Instructors assist with vetting auto-classification results in small groups, using student-collected recordings.

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