Titley launched the new Chorus detector at IBBM
Today Titley Scientific launched their new detector at the International Berlin Bat Webinar (Meeting). The Chorus detector is a weather proof device able to record both ultra- and audible sound. It has a built in GPS and is powered by AA batteries. This means that also birds, frogs, wolves and other audible animals may now be recorded.
      The news is totally new. Titley has hidden their cards well, not even sending out the information on their newsletters. As of today, even their web-page do not include information about this new detector, only allowing us to find it indirectly. Untill now Wildlife Acoustics have been alone on the market with audible detectors, and Titley's new device is a strong contribution to open competition.
      The detector will be described in the July issue of Fennoscandian Bats, if we are able to accuire one for testing.

4th EABDW in Edinburgh has been cancelled
The fourth European Alpine Bat Detector Workshop was planned to be held in Edinburgh during September this year. However, due to the Covid-19 pandemic, and practical issues connected to the outbrake, the planned workshop in Edinburgh has been cancelled. We are working on an alternative location this September, alternatively the one in Scotland will be organized next year.
More information will click here.

11th European Bat Detectors Workshop has been cancelled
Due to the European Bat Research Symposium in Turku (Finland) has been cancelled, there is no point in organizing the workshop.
      Since the first workshop (EBDW) in the Netherlands was organized in 1991, these workshops have always been organized in connection to the European Bat Research Symposium. Organizing the workshop just prior or after the symposium allows people to combine their travel. Furthermore, the workshop functions as an extention of the symposium.
      The next workshop will be held at the next European Bat Research Symposium, given that the EBRS is not organized as a webinar.

Wildlife Acoustics launch new passive detector
Today, Wildlife Acoustics announced their new detector the Song Meter Micro will be for sale from March. It is not launched as a «new generation» detector, but rather the «next in line», supplementing their SongMeter 4 Bat and SongMeter Mini Bat detectors.
      The SM Mini Bat seems to be a short lived detector. Microphones are always the weakest link concerning detectors due to its short life expectancy (1-3 season). With this built into the detector, this limits the detectors overall lifespan. Furthermore, the warranty is only for one year (shorter then the 3-year EU regulated warranty), indicating the manufacturer have low expectations of their product. Otherwise the detector is based on Bluetooth 4.0 communication to enable operations, a feature that will good for some users and an obstical for others.
      Earlier it was the competition between the manufacturers Wildlife Acoustics and Titley Scientific that cut the market prices of mass produced detectors. Today there is becoming more evident that cheap «home made» detectors such as the CloudedBats (WURB) detector or the BlueBox detector might be just as good, and a better alternative for the consumer. The cost of these two detectors are 500 and 160 euro. It is evident that Wildlife Acoustics have tried to meet this competition by producing their own alternative low-budget detector. Its real cost is around 345 US dollars (batteries and SD card excluded).
      The Song Meter Micro detector will be presented in the next number of Fennoscandian Bats, where we also hope to include some test results.

European Bat Research Symposium 2020/2021 cancelled
Due to the COVID-19 pandemic and uncertainties regarding its development this year, the symposium organizers have decided to cancel the conference. There is uncertainties weather the next conference will be in 2023 or 2024.
The organizers have decided to replace the conference with a webinar. It will be organized on 4th through 7th of May, just after the other European webinar (organized by Leibniz Institute) has been finished. This means that two events, which traditionally have been complementary, now have become competitors due to the poor timing.

First Danish wind turbine project ever to be legally stopped due to bats
A wind turbine project at Nørrekær Enge, just south of Limfjorden in Denmark, has included the planning of 36 new wind turbines to the existing ten. The area is close to a Natura 2000 area in which the presence of Pond Bats is one of the reasons the area has been designated special protection.
      A legal committee has withdrawn the construction permit given by the two municipalities involved. The reasons for the withdrawal is that (1)
The environmental report (EIA) is based on incorrect assumptions about the Pond Bat's way of flying and (2) The bat survey made in the area as a part of the EIA, has been insufficient given the size of the project area and the location close to the Natura 2000 site.
      The owner of the project is the energy company Vattenfall, which is 100% owned by the Swedish government. They have trough the project Vindval developed methodology on how to carry out EIA at wind turbine projects. This work is extremely extensive, going on for around 10 years. However, these standards Vattenfall has not applied on their own project abroad.
      More information will be available in the next number of Fennoscandian Bats.

Wind farm project stopped in Brittany by French court
The French web site Ouest France reported on 4 August that the Rennes administrative court has just cancelled the decree of 20 November 2017 which authorized the construction of a wind farm on the border between Caro and Monterrein, near Ploërmel (Morbihan).
      The decision was made by the court on 30 July, overturning an earlier construction permit. The construction of 8 turbines, reaching 178 meters in height, has now been stopped due to high biodiversity of bats.
      A total of 16 species had been recorded, and the court agreed that the risk of bat mortality was too high. The wind turbine company’s plan for preventing excessive mortality and monitoring was not sufficient

IUCN wish to protect bats from human-spread Corona-virus
On 12th April the IUCN Bat Specialist Group issued recommendations around the suspension of bat fieldwork, where handling bats or entering roosts was involved. The IUCN recommendations were issues to reduce any possibility of transmission of the COVID-19 virus (SARS-CoV-2) from humans to bats. At this time there is a high level of uncertainty about the likelihood of such transmission being possible. The recommendations apply the precautionary principle whilst a group of researchers are undertaking rapid risk assessments and we hope they will share their findings as soon as these are available for each global geographic region (they are starting with North America).

New European bat species discovered
The Gaisler’s Long-eared Bat Plecotus gaisleri has now been recognized as a European bat species, with a limited distribution in the Mediterranean basin. Published material based on field surveys and molecular analysis has now confirmed the species to occur in Italy (Pantelleria) (Ancillotto et al. 2020) and the islands of Malta and Gozo (Mifsud & Vella 2019).
      This species was described in 2004 using a specimen from north-eastern Libya. It was then dedicated as a subspecies (Plecotus teneriffae gaisleri) to the Canary Long-eared Bat. Earlier this subspecies has been associated to the Brown Long-eared Bat and then the Grey Log-eared Bat. Last it was placed as a subspecies to Mediterranean Long-eared Bat, before it was acknowledged as a separate species.

International renowned bat scientist Thomas Kunz died at age 81
Thomas Henry Kunz, distinguished biologist and Boston University Professor, passed away on 13th of April at the age of 81 due to complications of COVID-19. He had since 2011 spent his time at a nursing home due to brain injuries from a car accident while he attended a conference in Toronto.
      Kunz joined the faculty in the Department of Biology at Boston University in 1971. His research focused on the ecology, behavior, evolution, and conservation biology of bats. He is the author or co-author of more than 280 publications, and edited or coedited six books on the biology and ecology of bats. He was also involved in organizing the 10th International Bat Reserach Conference held in Boston during 1995. The professor was, perhaps, most productive at the age of 73 in 2011, when he coached seven PhD students and active grants from six different agencies.
      If you wish to honor Kunz, you may do so by a donation to the Tom Kunz Endowed Biology Fund. You can find more information here.
You can read about his biography at Bosten University. His obituary tells about his life and accomplishements, as well as Wikipedia.
      Best of memories...

6th International Berlin Bat Meeting has been cancelled
The Leibniz Institute for Zoo and Wildlife Research originally planned on organizing the 6th International Berlin Bat Meeting during 23-25 March 2020. Unfortunately it has now been cancelled due to the spread of the Corona virus (SARS CoV 2) which may give the desease COVID-19.
      Christian C. Voigt and Tanja Straka announced today in an e-mail:
«We regret to inform you that we had to postpone the upcoming 6th International Berlin Bat Meeting: The human perspective on bats due to the pandemic spread of SARS CoV 2. We are no longer allowed to host conferences in Berlin at this point. We envisage having the conference in March 2021.»

Neil Middleton publish milestone book
The new book "Is that a bat?" describes sounds we can detect on an ultrasonic detector. That is, all sounds, except those from the bats themselves. There is still a lot of lack in knowledge about the bats' ultrasound. Traditionally we have focused on the animals' search calls, feeding buzzes and commuting calls. This has been the case since the 1980's. But, for example, the animals' social sounds have generally been ignored. This could be males marking territories, or animals arguing in the air. Social bat calls were first highlighted as late as 2014, when Neil Middleton published his book on this topic. So far, Middleton is alone on publishing such a book.
However, Neil Middleton has made another step. He has now included all sounds, except bats, in his new book. This is of course very useful, since almost as often we come across sounds we cannot identify. Amphibians, birds, grasshoppers and small rodents can all emit ultrasound on a regular basis. Several of these sounds are species specific. In addition, a number of mechanical sounds may find its way to the detector. All of this can cause confusion when we try to identify our recorded sounds. So the knowledge Middleton conveys in his latest book is absolutely useful to any bat scientist.
      The book is for anyone who works actively with bat sounds, and is strongly recommended. It should be a permanent
inventory of any library dealing with bats.
      The book was published in January, and NIFF was sent a copy by the author this week. NIFF has been mentioned several times, including from the Askim workshop in 2018. More on this comes in the book review which will be included in the
next issue of Fennoscandian Bats.

Bat trips to see hibernating bats at Mønsted Limestone Mines
In the late 1990s Mønsted started with guided tours to see hibernating bats during February. They offered people tours on both Saturday and Sunday during both winter holiday weekends. These tours were very popular and 50-150 people participated on each tour.
      However, winter is a vulnerable time for bats
since they are in hibernation. Disturbances may significantly reduce the bats' possibility for survival, and thus such activity has generally been taboo. Most serious researchers have rejected such activity. It was therefore controversial when Mønsted started with guided tours during winter. Although only a limited part of the mines are visited, and where relatively few bats have been found, many people have been critical to this practice. When Mønsted opened for winter tours, this inspired other less serious companies to start guiding as well.
However, studies from both Mønsted and Thingbæk show that, despite human winter visits, the number of hibernating bats have increased over the years.
      Mønsted limestone mines have two daily tours of the mines during the entire Danish winter holiday

11th European Bat Detector Workshop to be organized in Finland 2020
The European Bat Detector Workshop was first organized in the Netherlands during 1991. Since, this workshop has been organized in connection to the European Bat Research Symposium (either just before, or after). This year the 15th European Bat Research Symposium will be organized in Turku during 3-7 August (check our meeting calender at
      So it is the pleasure of the Nordic Chiroptera Information Center (NIFF)  to invite you to the 11th European Bat Detector Workshop, which will be organized in Kausala, 133 km east of Helsinki.
      The five day (four night) workshop will include peer-reviewed oral presentations, posters, workshops, and sessions for exchanging experience in field practices.

      The aim of the workshop is to get field training in practical bat work, especially the use of various models of both passive and active bat detectors. This will improve our 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.

New «handbook» include all the bats in the world
Volume 9 of the Handbook of Mammals of the World is the latest issue in a book series containing all the mammals in the world. The latest and last volume addresses all the so far 1,400 known species on our planet.
       Each species is covered with text, maps, illustrations and references. According to Lynx publisher, the information should be updated, but NIFF has information that a lot of key knowledge might not be included.
Still, the book is the most comprehensive work on our bats ever published.
       NIFF has received a copy
to be reviewed.
The book review will appear in the next issue of Gudnjoloddi and Fennsocandian Bats.

Bird species of the Eurasian steppes will reveal the origin of the Party-colored Bat
The geographic origin of the Party-colored Bat (Vespertilio discolor) has so far been unclear. It has always been presumed that they originated from the steppe regions of South-eastern Europe, north of the Black Sea and the Caspian Sea. Furthermore, it was presumed they foraged in grassland during summer, followed by mating activity and hibernation in mountain areas containing cliffs.
      A new literature study has as objective to review bird species with similar ecological and habitat requirements as the Parti-colored Bat. This study might shead some light to the mystery that has followed this species since the 1800's.
      The study is being carried out by Leif Gjerde from NIFF.

Wildlife Acoustics discontinues the SongMeter 3
The USA based manufacturer Wildlife Acoustics recently announced that from July 2019 their second generation of passive detectors, the SongMeter 3, will be out of production. The SongMeter 3 was originally launched in May 2014 as a new generation of the perfect detector. It was developed based on the experiences from the SM2 detector. However, the SM3 was considerably more expensive and a lot heavier. The size and weight made it impractical for field use. The SM3 lasted only five years.

Increase in number of hibernating bats in Swedish mines due to climate change?
During 1980 to 2017, hibernating bats were montored at three abandoned mines in southern Sweden. Taberg and Kleva mines each have around 1.5 km of accessible passages. Here, a maximum of 517 (Taberg) and 132 (Kleva) bats are recorded, divided on 6 species. Ädelfors is a small mine with only a maximum of 22 individuals.
      The number has been constant for
the Daubenton Bats and Brown Longeared Bat. In contrast, Wiskered Bat, Brandts' Bat and Nathusius' Bat have increased greatly in numbers. The Northern Bat have shown a significant but weak decline.
The same trend for the same species has also been demonstrated in continental Europe and the British Isles. This indicates that there is a common cause for the changes in species populations.
The authors are bold enough to suggest that there are climate changes that might cause the changes, without any further evidence of this.

New bat detector: Titley Scientific launches the Anabat Scout
Our two large manufacturers seem to go separate ways in regards to developing new detectors. While the USA based firm Wildlife Acoustics are discontinuing their production of active detectors for field use, the Australian firm Titley Scientific have chosen to launch yet another active detector for fieldwork. Three years ago they launched «the Walkabout». And this November a new detector was announced,  the Anabat Scout.
      The Anabat Scout is a simpler model compared to the Walkabout, but also at a lower cost. It records in full spectrum, and include heterodyne, auto-heterodyne and frequency division. A built in GPS enables to use it for transects, since the recordings and GPS are both time-stamped. An interesting feature is the inclusion of a bat counter. Sounds of emerging and returning bats can be time stamped by two separate buttons. This is a useful tool when counting emerging bats at colonies. Titley Scientific have been creative when developing this detector, making them the first manufacturer with this feature on a detector.

New guidelines: Guidelines for consideration of bats in lighting projects
The authors tried to compile available evidence related to the effect of artificial light at night on the European bats. Based on the current state of knowledge, solutions are proposed concerning possible ways to avoid, mitigate and compensate the adverse effects which lighting projects may have on bats and their functional habitats. The authors also outlined research priorities for future studies, required for in-depth understanding of the problem and assessing efficiency of proposed mitigative measures.
      These guidelines were developed by the EUROBATS Advisory Committee in collaboration with external experts in pursuance of Resolution 7.13 on Implementation of the Conservation and Management Plan.
      NIFF hope to make a book review, which in part will be published here, with more details in the next number of Fennoscandian Bats.

New book: Bat Roosts in Trees
This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project.
      It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs.
      It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access.
      It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals.
      NIFF hope to make a book review, which in part will be published here, with more details in the next number of Fennoscandian Bats.

Mating season for Vespertilio murinus has started
This species forage above lakes during summer, and migrate to nearby cities during fall where it mates and hibernate. During the mating season it performs its display flight with a sound audible to most people below 55 in age. Tall buildings are chosen, typically apartment buildings of 9 stories or more. However, industrial buildings, silos, churches, quarries or even natural cliffs may be selected if they are tall enough.
      The stronghold of the species lie in southern Scandinavia (south of Oslo-Stockholm), which include Aarhus and Copenhagen. It is also commonly found in northern Germany. In the rest of Europe it seems to have a patchy distribution. However, the species absence probably reflect the lack of bat workers surveying this species during the fall months, rather then its actual distribution.
      The season starts in September, and last till Christmas if the weather permits. Their display flight may still be observed during 0
ºC and with landscape covered in snow! It is found as far south as Slovenia and Switzerland, and fall records of migratory individuals in the Pyrenees. During recent years it has been reported annually from bat hospitals in the south of England.
A web page has been designed for this bats' fall activities. It contains information on the fall distribution of the Parti-colored Bat in Europe, including behaviour and ecology of its display flight. The web page encourages people who study the advertisement calls in this species, to cooperate and share information with the European project. The web page may be viewed at

Helpline with record high of phone calls concerning bats in distress
This summer NIFF reached a record high of phone calls from people who found bats in distress. The reason for this could be many, but this summer was extremely hot and dry with a number of weather records broken. Furthermore, the season seems to have been earlier than normal.
      People send the strangest messages using e-mail, phone or SMS. NIFF's work is done on a volunteer basis, so we have not had the capacity of following up all the calls. The majority of calls we received were from Norway, and most people unfortunately only take contact once.
      Most of the requests refer to juveniles which just learned to fly. We always ask for pictures of the bats, since they give valuable information on species identification and age. The bat on the illustration picture (right) show a juvenile Eptesicus nilssonii, which is aged by its proportional larger head and little grey spot on its crown. Photo from 21 July.

Bat Call Reference Library Collection Trip in Trøndelag
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, five people joined a post-workshop expedition to Trøndelag (Central Norway) during
6. to 9. of August. Chris Corben (USA/Australia), Leif Gjerde and Arnold Andreasson participated as specialists from the working group, while Laura Alsina (Spain) and Angel Iglesias (Catalonia) also joined.
Three colonies were visited on three separate days to collect calls from emerging bats. Also the surrounding habitats were visited. The species were 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. More details will also be included in the next number of
Fennoscandian Bats. A photo gallery will eventually be available on

3rd European Alpine Bat Detector Workshop organized in Askim, Norway
A handful of people from 9 countries participated during the 3rd European Alpine Bat Detector Workshop which was organized in Askim (South-Eastern Norway) during 2. - 6. August 2018. This series of workshops were first organized in Trenta (Slovenia) during 2012, followed by the second in Vercors (France) in 2015. So this years workshop was the beginning of a new tradition, with the third of its kind.
      The workshop was organized by Leif Gjerde and Arnold Andreasson, both from NIFF, who were responsible for the program. The aim of the workshop was to provide field training in practical bat work, especially with the use of various models of both passive and active bat detectors.
The results from the workshop will be included in the Proceedings. More details will also be included in the next number of Fennoscandian Bats. A photo gallery will eventually be available on

10th Anniversary of the European Bat Detector Workshops
In 1991 it was taken initiative to organize the 1st European Bat Detector Workshop, which was held in the Netherlands. This was the beginning of a new tradition of organizing a detector workshop just prior or after the EBRS, either in the same or a neighbouring country.
      During the European Bat Research Symposium in Kroatia in 2014 the workshop had been ignored, making it necessary with a last minute get-together after the symposium, with only a handful people. This barely saved the 9th EBDW. However, it was with delight when during the last day of the Croatian symposium that the organizer of the next symposium in Donostia explicitly stated that they would also organize the 10th European Bat Detector Workshop. However, this did not happen. So NIFF and Bluebat took the initiative to organize the 10th workshop in Bidarrai. Now the structure of planning and organizing these workshops have been changed to prevent future fall-outs.
      The Spaniard Juan Tomás Alcalde was a participant in the Netherlands 26 years earlier, and rejoined the anniversary workshop in 2017 (see illustration picture right). The photo gallery from the workshop is now available on
