SonoBat Field
Techniques Workshop

Agua Caliente Regional Park • Tucson, AZ
April 15-April 18, 2011

The SonoBat software package, developed by Joe Szewczak (Arcata CA), is one of the premiere bat echolocation signal analysis packages available to display, analyze, and discriminate between bat calls. The SonoBat Field Techniques Workshop in Tucson takes advantage of the rich local bat diversity to highlight state-of-the-art acoustic monitoring techniques. This workshop provides intensive training in the use and implementation of SonoBat for recording bat echolocation calls and designing acoustic inventories that emphasize full-spectrum acoustic techniques as recommended by the new USFWS guidelines for Wind and Wildlife when species ID is important.

Program Details
Agua Caliente, meaning hot water, is a unique 101-acre park with a perennial warm spring, located on the far northeast side of Tucson. Literally an oasis in the desert, Agua Caliente contains spring-fed ponds that support diverse wildlife and fish populations, as well as attract many of the 29 bat species known from Arizona. By partnering with our local host at Pima County Natural Resources, Parks and Recreation (NRPR), we will highlight park resources at Agua Caliente and demonstrate protocols for implementing bat inventory and monitoring programs with a special focus on western bat species and habitats.

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. A detailed agenda will be provided to all registered participants prior to the course.

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.

One session: April 15-18, 2011 (Friday-Monday). Class size: Limited to 20 participants. Location: Auga Caliente Regional Park, Tucson AZ

 

Workshop Instructors:
Joe Szewczak,
B.S.E. (1980) Duke University, Ph.D. (1991) Brown University, is an Associate Professor at Humboldt State University in Arcata, CA. His research has investigated the physiological capabilities of bats and other small mammals, from cold hibernative torpor to the intense demands of flight and high altitude, and the physiological ecology of bats,. His teaching includes “Using SonoBat for Non-invasive Bat Monitoring” for the University of California, “Biology of the Chiroptera” at Humboldt State University, and “The Ecology and Conservation of California Bats” through San Francisco State University. Joe has also taught acoustic monitoring workshops for BCI and other groups in California, Oregon, Arizona, Washington, South Dakota, Kentucky, and Pennsylvania. He is the developer of SonoBat software to analyze and interpret bat echolocation calls and is currently developing automated bird and bat acoustic monitoring and identification methods for the Department of Defense (SERDP) and other agencies.

Janet Tyburec, B.A. (1989) Trinity University, a full-time employee at Bat Conservation International, Inc. (BCI), from 1989 thru September 2002, has been involved in the structure and execution of training workshops since the inception of BCI's workshop efforts in 1992. She has been extensively trained by BCI founder, Merlin D. Tuttle. Over the years, she has personally taught over 1,500 wildlife biologists, land managers, and students of conservation in the course of presenting over 100 field workshops. She currently oversees all training and instruction at BCI's Arizona, California, Kentucky, and Pennsylvania locations. She continues to be involved with many aspects of BCI's workshop program and its growth as a contract employee, a position she has held from September 2002 to the present. She has also contracted with other federal and state agencies, including the USDA Forest Service, USDI National Park Service and the Department of Defense to conduct custom training workshops for directors, staff, seasonal employees, and volunteers.

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.

Lectures/Discussions:
Lectures and demonstrations cover a full range of bat echolocation and acoustic monitoring subjects, with a focus on the use of SonoBat software for designing inventory and monitoring programs for bats. Topics will include:

• Introduction to bat bio-acoustics, echolocation, and bat detectors
• Hands on demonstration with available bat detector models
• Bat detector use in the field for active and passive monitoring
• Bat monitoring program designs and choosing the right bat detector for the job
• Introduction to SonoBat software for recording and signal analysis
• Call characteristics for bat identification on the basis of echolocation calls
• Auto-classification using SonoBat 3.0, data handling, storage, and interpretation

Evening Field Practicals
Instructors will provide guided, hands-on demonstrations during evening and night-time field practicals. Participants will be split up into small groups for added opportunity for individual instruction. Topics will include:

• Active monitoring using bat detectors, tips for following bats
• Key morphological characteristics to help identify bats “on the wing”
• Passive setups using bat detectors and digital audio recorders (e.g., Pettersson D240x and Samson Zoom)
• Passive deployment of direct recording detectors (e.g., AR125, Pettersson D500x, SM2)
• Implementing mobile acoustic transects
• Addressing power, security, and weatherproofing for long-term, passive deployments
