European Bat Detector Workshop
5 - 9 August 2017
Bidarrai, The Basque Country (France)
- The Pyrenees
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. With this years conference in
Donostia (the Basque country), the 26 year old tradition was almost forgotten.
So it is the pleasure of
Nordic Chiroptera Information Center (NIFF) and
Bluebat to inviting you to
the 10th European Bat Detector Workshop.
The event will be organized in Bidarrai
(the Basque country) just on the French side of the Spanish border, only 76 km
from the conference in Donostia (San Sebastián).
The workshop will start on the same evening
as the conference ends, allowing people to travel directly from one
event to the other.
The European Bat Detector Workshop has traditionally been organized
in connection to the European Bat Research Symposium. However, from 2011
there has been no practice for the symposium organizers to also organize the workshop.
The aim of the workshop is
to get field training in practical bat work. This includes the use of various
detectors, and capture techniques.

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
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
training in using active detectors, such as the Petersson (D240X, D980), the
AnaBat Walkabout, the EchoMeter and misc. flat screen versions.
to operate the passive detectors produced by Pettersson (D500x), Titley (AnaBat Express and AnaBat
Swift), Mini Batcorder (EcoObs) and Wildlife
Acoustics (SongMeter 2, 3 and 4).
- Analyzing bat calls by using
software from Pettersson (BatSound), Titley (AnaLook), Biotope (SonoChiro 4) and Wildlife Acoustics

workshop will end on the 9th of August at 1200 h.
We will have at
our disposal active and passive ultrasound detectors from three different
producers (Titley Scientific, Petterson Electronic and Wildlife Acoustics). This
will give the participants possibility to get familiar with different type of
work equipment and possibilities that they offer.
During the day we will analyze
the recordings from previous evenings and attendants will be invited to have 20
In the evening we will divide in groups of five people that
will check different areas for bats. Each group will have at least one
experienced bat worker, who will lead them and be responsible for the quality of
the collected data.
