Paul Howden-Leach Kaleidoscope Pro Training Course

This one day course was designed specifically fo ecological consultants. The course introduces participants to Wildlife Acoustics analysis software, Kaleidoscope Pro, specifically its ability to analyse large data sets. The course will focus on both the free and full versions of the software and its application within the profession. The course will be led by Wildlife Acoustics' Paul Howden-Leach, an expert in Kaleidoscope Pro. All profits from the course will go to the Bat Conservation Trust.

Register for and attend either workshop, and you'll be entered into a drawing to win a Kaleidoscope license – a $1,499 (USD) value.

Upcoming Courses:

Dates: TBD

Course Content Includes:

Understanding bat echolocations – Physics of sound
Principals of bat detectors, including differences in technology relating to zero crossing, full spectrum, heterodyne and time expansion. How to use the free Kaleidoscope viewer, faile converter and noise scrubber. Dealing with large data sets using Kaleidoscope pro auto ID software Principals of cluster analysis within Kaleidoscope and its applications Exporting the results.

This will be a classroom based course, however equipment will be used to demonstrate key concepts.

Prior Knowledge: A basic understanding of bat identification is recommended although not essential.

Equipment: All participants must bring a laptop with Kaleidoscope Pro installed. A training licence key will be given out on the course to activate the full version of the licence for a two week period. Participants can bring examples of their own data; however this is not essential as data will be provided.

Cori Lausen Bat Acoustics Training and Analysis Course

The Wildlife Acoustics Bat Acoustics Training and Analysis Course covers the principles of bat echolocation an equipment overview and deployment tips, hands-on experience with Wildlife Acoustics detectors and discussion about the various software components for configuration and analysis.

Upcoming Courses:

Dates: TBD

Course Description

Cori Lausen

These courses cover the principles of bat echolocation and include hands-on experience with a variety of detectors including the Echo Meter Touch, and software, including Kaleidoscope Pro. The objectives of the comprehensive acoustic courses is to prepare bat detector users to select appropriate models of detectors for their acoustic needs, to learn how to acoustically identify bats, and to analyze large datasets of recordings.

Topics include:

  • Understanding bat echolocation – properties of sound, effects of clutter, etc.
  • Principles of bat detector technology, including zero-cross vs full spectrum
  • Basics of bat species identification – pulse shapes and terminology
  • Bat detectors as 'tools in a toolbox'.
  • Principles of passive and active monitoring
  • Critical information for appropriate site selection and detector deployments (varying deployments appropriately for the microphone, and detector settings)
  • How to do active monitoring with detectors including Echo Meter Touch (practice in field)
  • Species identification of all North American bats with in-depth focus on regional species
  • Hands-on practice recording bats and analyzing calls -- Zero-crossing and Full Spectrum
  • Analysis of calls – auto-identification software Kaleidoscope Pro with some additional software packages (see course-specific details).

See course-specific descriptions on registration sites for detailed topics.


Courses vary from 3 – 6 days. Techniques and Comprehensive courses include a field component. Visit course registration links for details, or the Bats R Us website.

About Your Instructor, DR. Cori Lausen

Cori Lausen Cori Lausen

Dr. Cori Lausen, bat biologist, received her PhD in bat ecology in 2007 from the University of Calgary in Alberta. Prior to graduate studies, Cori taught high school sciences. She now works as a research scientist and bat specialist with Wildlife Conservation Society Canada. Her research interests have largely focused on winter bat ecology and hibernation. She has taught bat acoustics courses since 2008, and was instrumental in the development of the North American Bat Monitoring Program (NABat). She has helped to implement NABat acoustic monitoring, including with both US and Canada's national park systems.

Required Equipment

Attendees must bring their own laptop, ideally running a Windows environment, earbuds/earphones, headlamp. Attendees are encouraged to bring a compatible iPad or iPhone for use with an Echo Meter Touch module. Attendees are also encouraged to bring any passive bat detectors that they'd like to learn more about and practice with in the field.

In preparation for the courses, attendees may wish to view the Song Meter SM4BAT, Echo Meter Touch and Kaleidoscope Pro tutorial videos prior to the course.

Download the free 15‐day trial version of Kaleidoscope Pro to your laptop. You will be issued a 30 day license code at the course.

ERM Bat Acoustics Training and Analysis Course

Kaleidoscope Software

Wildlife Acoustics and the bat biologists at ERM are collaborating to offer training courses in how to conduct bat acoustic surveys and identify bats from their calls. Experienced and new bat biologists are welcome to take advantage of this convenient training opportunity.

Upcoming Courses:

Dates: TBD

Registration and Questions:

Please e‐mail Michael Fishman at ERM: Michael.fishman@erm.com

IMPORTANT! Preparations Before You Attend the Course:
  • Download the free 15‐day trial version of Kaleidoscope Pro to your laptop (and bring your laptop to the course). We will have call files for you to process and identify.
  • Review Kaleidoscope Pro tutorial videos.

Course Description

The course will help you:

  • Select productive sampling sites and set up bat detectors in the field
  • Download data from bat detectors and manage large volumes of data
  • Use Kaleidoscope Pro Software to process call files for auto‐classification
  • Consistently manually vet bat call files to classify species
  • Learn the metrics needed to identify Myotis species

The USFWS's 2016 Range‐Wide Indiana Bat Summer Survey Guidelines state, "acoustic surveyors should have completed one or more of the available bat acoustic courses/workshops, or be able to show similar on‐the‐job or academic experience". Taking a course is the fastest way to expand your experience with bat acoustic surveys and manual classification of bat calls. ERM's and Wildlife Acoustics' Bat Acoustic Training Course will demonstrate the necessary skills, knowledge, and proficiencies you need to master before you can reliably conduct bat acoustic surveys.


Michael and his team stand ready to answer any other questions you might have about the course, such as downloads and other pre-course preparation.
