European Alpine Bat Detector Workshop
6 August 2018
The European Alpine Bat Detector
was first organized in Trenta (Slovenia) during 2012, followed by the second in
Vercors (France) in 2015. Thus, this years workshop is the beginning of a new tradition, with the
third of its kind.
Nordic Chiroptera Information Center (NIFF) organized
the 3rd European Alpine Bat Detector Workshop, which was held in
(South-Eastern Norway), only 55 km
from downtown Oslo and 37 km from the Swedish border.
The aim of the workshop was
to get field training in practical bat work, especially the use of various
models of both passive and active bat detectors. Organizers were Leif Gjerde and
Successful workshop finished
We thank everyone who participated in
Askim, and the people who participated in the bat call reference library
collection trip afterwards.
The results from the workshop will eventually be
available electronically (pictures, presentations and bat call recordings),
while the Proceedings will include the articles describing the talks, activities
and results from the workshop.
I am sure everyone will enjoy their knowledge and
experience from the workshop, and the stay became a platform for future work and
Hope you will join us at the 4th European
Alpine Bat Detector Workshop in September 2021.

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).

The Bat Fauna
The bat fauna of the Oslo area will gradually be presented here.
A common bat which usually is found during fall display flight around tall
apartment buildings in the cities.
The most common bat. Cosmopolitan (all habitats). Locally in large numbers.

- Vespertilio murinus
- Myotis daubentonii
- Myotis mystacinus
- Myotis brandtii

Start: The workshop building will be accessible from 1500
h on the 2nd of August, and the program starts at 1800 h.
workshop will end on the 6th of August at 1000 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 who
will check different locations
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.

Some distances and travel
|Gardermoen (Jessheim) -
|Torp (Sandefjord) -
The nearest airports from
1. Gardermoen - OSL (Oslo) - 99 km (1h 37min)
2. Torp - TRF (Sandefjord) - 172 km (2h 14min)
3. Landvetter GOT (Sweden) - 241 km (2h 49min)
Airplane companies leaving from Torp (Sandefjord Airport) are a.o. Norwegian
Air Shuttle, Ryan Air (Irish), KLM (Dutch), Wizz Air (Hungarian).
The travel costs from Stansted (London) at 0940 h to
Gardermoen on 2nd of August, and return (arrival Stansted at 1630 h) are 98
pounds (checked 6th Jan.).
Train from Gardermoen airport
NSB is the main company. From Gardermoen airport there is also "Flytoget" or
the airport plane. They are both state owned, but the airport plane is a lot
more expensive. Tickets for these are bought at separate machines and at
separate ticket counters, but just few meters apart. So this can be confusing.
NB! The airports name is Gardermoen, but officially it is
"Oslo Lufthavn". So searching databases you might need to use the official name.
On train platform Gardermoen might be used.
Train from Gardermoen airport to Oslo S (Oslo
Sentralbanestasjon). At Oslo S you need to change train for Askim.

Bat Call Reference Library Collection Trip
6th - 9th August 2018
During the 10th
European Bat detector Workshop in Biddarai (the Basque Country) in 2017, there
was established a working group whose aim was to standardize methods for
collecting bat calls in the field. Special focus was on (1) developing
microphone standards, (2) establishing a bat call reference library and (3)
enabling inexpensive high quality detectors and microphones.
In connection to
this work, the group will have a post-workshop expedition to Trøndelag (Central
Norway). Three colonies will be visited on three separate days to collect calls
from bats emerging the colonies, and from the surrounding habitats.
The species are
from known colonies of Myotis brandtii, Myotis mystacinus and
Eptesicus nilssonii, making species identification safe for the calls
collected. Furthermore, no nearby colonies exist of any confusing species.
The results from
the trip will be included in the Proceedings.
There will be a DVD publication after the workshop which include
pictures, sound files, 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

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 Norwegian.
Deadline for contributing article manuscript is
31 December 2018.
