16th European Bat Research Symposium


11th European Bat Detector Workshop

In connection to the European Bat Research Symposium every three years, it has since 1991 been a tradition to organize a bat detector workshop just before or after the conference. The aim of the course is to get field training in practical bat work. This includes the use of various detectors, both active and passive. But also improve our skills on bat call analysing software


Responsible organizers:

  • Leif Gjerde (NIFF); E-mail: niff@flaggermus.no; Mobile phone: + 47 40228817

  • 16th EBRS Organising Committee (info@ebrs2024.com; Natural Sciences Museum of Granollers)

Dates: 6 – 10 September 2024

Location: The workshop will take place in the Sant Llorenç del Munt i l'Obac National Park, located 25km north Barcelona. Accommodation will be arranged in the village of Mura, where the theoretical sessions will also take place.


The objective of the workshop is to improve training and knowledge of the latest technology and experience on field identification of flying bats. The mixture of novice and well experienced bat workers (and everything between) enhances the learning process by self awareness and development.

The target group is idealistic bat workers (enthusiasts/idealists, NGO's and scientists) who is or will work with bats in the future. Students and NGO's may apply for reduced fee. Commercial bat workers will be excepted if there is space.

  • Learn the basic theory of bat identification with the aid of ultrasound devices.

  • Field training in using active detectors, such as the Petersson (D240X, D1000), the AnaBat Walkabout and misc. flat screen versions.

  • Learning how to operate the passive detectors produced by Pettersson (D500x), Titley (AnaBat models) and Wildlife Acoustics.

  • Analyzing bat calls by using software from Pettersson (BatSound), Titley (Anabat Insight and AnaLook) and Wildlife Acoustics (Kaleidoscope).

The results from our surveys will be published in the proceedings for the workshop.



  • Chris Corben – creator of AnaBat/ZeroCrossing

  • Leif Gjerde – EBDW veteran (been to all since 1993)

  • The history of ZeroCrossing ― by Chris Corben

Some detectors available for testing at the workshop:

  • AnaBat (including Chorus, Ranger, Swift, Express and Walkabout)

  • Pettersson (D100, D500x, D1000x)

  • SongMeter (most of their old models, hopefully some of their new ones)

More models to be expected! And mics to be tested.

Software training:

  • BatSound 4.4

  • AnaLook + AnaBat Insight

  • Kaleidoscope


Exclusive offer to participants:

  • 20% discount on any Pettersson bat detector/­micro­phone (based on list prices)

  • Purchase of BatSound 4.40 at the price of €88 (excl. VAT) (normal price €264)

Offer valid until 31 September 2024.


The expenses will be at your own. The workshop is carried out on a low budget principal, meaning everything is based on self cost. Cost estimates will be provided soon.


Registration is now open. The deadline for registration is 15th June 2024. Please contact Leif Gjerde (e-mail niff@flaggermus.no) and provide the following information as early as possible:

  1. Your motivation for joining the workshop (the workshop is for people working with bats, or planning to do so!)

  2. The time you expect to arrive

  3. If you travel by car

  4. What detectors you will bring (if you have any)

  5. Title of talk (if you expect to have one)

  6. Abstract of talk (if you are having a talk. Deadline 15th July 2024)

  7. If you bring with your own food or not


Note: Information from the workshop will be available to the public. This means that pictures, names of participants, abstracts, power point presentations and manuscripts from talks will all be made available in our Proceedings and/or web-pages. If you have problems with any of this, you need to contact the organizer to agree on an alternative solution.
