Wildlife Acoustics Bat Detector Training Course

In response to the growing demand for SM2BAT+ and EM3 training, Wildlife Acoustics is pleased to announce the Wildlife Acoustics Bat Detector Training Course. This course will provide a background on the principles of bat echolocation, hands-on experience with the SM2BAT+ and EM3, and discuss the various software components for configuration and analysis.

BAT ECHOLOCATION 101 – Participants will learn:
Why bats produce ultrasound, and why different bats produce different frequencies.
What a bat call looks like and what affects the shape of the bat calls.
What the clutter continuum is and how this affects bat echolocation, including precautions and difficulties with acoustic analysis.
Terminology related to bat acoustics – call/pulse, sequence, pass, characteristic frequency, etc.
The properties of sound, and why ultrasound presents a challenge for bats and bat researchers.
How a species’ ultrasound and bat ecology and morphology are inter-related.
SPECIES IDENTIFICATION 101 – Participants will learn:
How one can predict what type of ultrasound a given species will produce, based on its ecology.
What key features in a call shape and sequence pattern allow you to differentiate species.
Basic call features of North American bat species.
Difficulties inherent in telling some bat species apart.
Methods used to tell species apart – manual and statistical techniques.
HARDWARE 101 – Participants will learn:
What is a bat detector and how does it work.
What are the different types of detectors and how do the technologies differ (audio and data) – heterodyne, full spectrum, zero-cross, frequency division.
How is full spectrum data collected and how is zero-crossing data collected.
What are the advantages and disadvantages of full spectrum vs. zero-crossing data.
What types of detector technologies are used in what scenarios – passive monitoring, listening vs. recording, active monitoring, reference call collection, etc.
FIELD APPLICATIONS OF BAT DETECTORS 101 – Participants will learn:
When to use active monitoring and why.
Where to situate a passive detector, and what to consider in the placement of such units.
How to deploy a passive detector – solar considerations (latitude appropriate), housings (when they are needed, and how to accommodate various weather conditions), site selection (where to put a detector and things to avoid; optimizing post-field analysis).
How to collect reference calls and why.
Creative methods for deploying detectors – dealing with issues such as weather, vandalism, landscape features, etc.
WILDLIFE ACOUSTICS HARDWARE – Participants will learn how to use and program the following units:
WILDLIFE ACOUSTICS SOFTWARE – Participants will learn how to use the following software associated with the Wildlife Acoustics equipment:
Song Meter Configuration Utility
ANALYSIS OF ACOUSTIC RECORDINGS – Participants will learn:
How to convert data from the SM2BAT+ to meet analysis needs – full spectrum vs. zero crossing options, and advantages and disadvantages of analyzing in each format.
How to analyze data in SonoBat (cursory overview – please refer to SonoBat for training on in depth use of software).
How to analyze data in AnaLook (cursory overview – please refer to Analook for training on in depth use of software).
