European Bat Detector Workshop
5 - 9 August 2017
Bidarrai, The Basque Country (France)
- Program -
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 was 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 started on the same evening
as the conference ended, 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 was
to get field training in practical bat work. This included the use of various
detectors, and capture techniques.
Responsible organizers were Leif Gjerde
(NIFF) and Didier Mauuary (Bluebat). Local organizers were Juan Tomás Alcalde, Nicolas Bernos (CPIE, the
Basque Country) and Nicolas Valet (Auddice).
Photo gallery is on the way
Any pictures you might have taken, and still
not delivered, it would be nice to receive a copy
We have already received a lot of material
from the participants. So every participant we think might have additional
recordings, pictures, presentations or other information, will be contacted
on an individual basis.

The objective of the workshop was 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.

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
Equipment we had available
for testing were:
- AnaBat Express (Titley Scientific)
- AnaBat Swift
- D500x (Pettersson Elektronik)
- SongMeter 2 (Wildlife
- SongMeter 4 Full Spectrum
- Pettersson (D100, D240x, D980, D1000x)
- Titley Scientific (Walkabout)
- Wildlife Acoustics (EchoMeter)
- BatSound 4.2
- SonoChiro 4
- Kaleidoscope Viewer

The Pyrenees and the Lower Navarre region
Lower Navarre is a collection of valleys in the foothills of the
a commune of the
Pyrénées-Atlantiques department in southwestern France. It is a Basque
province of Lower Navarre. It is surrounded by low hills. The river Nive runs
through the village.
The Bat Fauna
The bat fauna of the Basque country will cradually be presented
here. So watch out for updates. So far we have confirmed the Nyctalus
lasiopterus and Pipistrellus pygmaeus, and some new species are added
to the list. The list is on 28 species!
Closest record was made in the Western Pyrenees just ca. 120 km to the
south-east of Bidarrai. One male was caught on 25 July 2009 in the mountain pass

Start: The workshop building will be accessible from 1700
h on the 5th of August, and the program starts at 1800 h.
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.

There will be a DVD publication after the workshop which include
pictures, soundfiles, analysis and statistics.
addition we hope to publishing
the results of our bat detector workshop in a special issue of Gudnjoloddi (ISSN
0809-2362). It will be published by NIFF and Bluebat together. The title will be "Proceedings
from the 10th European Bat Detector Workshop, held in Bidarrai (Basque country)
during 5th to 9th of
Leif Gjerde and
will be editors of the proceedings. It is expected that each lecture will be
published as a separate article in the proceedings. If no manuscript is
received, we will publish the abstract alone.
There is no limitation for the length of the articles, but the contents should
be relevant to the talk. The proceedings will be in English entirely. There will
not be included abstracts in Euskara, French or Norwegian.
Deadline for sending
1st of July.
Deadline for contributing article manuscript is
31 December 2017.
