See below for details about the new features included in this release, as well as a handy table to see which version of Kaleidoscope is right for you, and some useful tutorial videos.
New features include:
New Bat Auto-ID Classifiers
New bat classifiers for North America, Neotropics, Europe and South Africa as well as updated common names for some species. The default setting for classifiers is now “Balanced” which is a useful compromise between the more sensitive and more accurate options.
New time-saving workflow features
New features in the results viewer window include:
• When opening a saved results spreadsheet, a file browser allows you to easily locate the folder containing the corresponding input files
• Bulk ID multiple selected rows
• Bulk copy files in selected rows to a specified folder
Full support for GUANO metadata (Kaleidoscope Pro only)
Kaleidoscope now reads and write GUANO information alongside Wildlife Acoustics metadata (WAMD). This will been shown in the file at the end of the metadata notes window.
It’s that time of year again. Spring has sprung earlier than ever, and the survey season will very soon be under way. In this post we look at some of the fantastic new bat detectors due for release this spring.
The Anabat Swift from Titley Scientific is based on the excellent design of the Anabat Express and records in full spectrum as well as zero crossing. Users can choose between sample rates of 320 or 500kHz and a built-in GPS receiver automatically sets the clock, calculates sunrise and sunset times and records the location of the device.
Echo Meter Touch 2
The Echo Meter Touch 2 is perfect for bat enthusiasts and students and will let you record, listen to and identify bat calls in real-time on your iPad, iPhone or iPod Touch. All you need is your iOS device, your Echo Meter Touch 2 and the Echo Meter Touch App which is a free download from the iTunes store.
Echo Meter Touch 2 Pro
Designed for consultants and professional bat workers, the Echo Meter Touch 2 Pro has all the great features of the Echo Meter Touch 2 but with additional user options such as an adjustable sample rate (256kHz and 384kHz), adjustable gain and advanced trigger settings.
The compact Batcorder Mini has a very simple user interface with just a single button to start and stop recording. Calls are recorded in full spectrum onto the built-in memory (64GB) and the internal lithium-ion battery is chargeable by USB. A built-in GPS receiver sets the time, date and location.
Ultramic384 Ultrasound Microphone
This high performance ultrasound microphone will connect to a USB port for real time listening and can also be used as a stand-alone recorder when used with a USB battery. An internal microSD card slot allows data to be recorded.
The Batcorder GSM is designed for use at a wind turbine site and includes a microphone disk which is inserted directly into the turbine nacelle. The unit runs off mains power from the turbine and a GSM function lets you receive status messages, reassuring you that everything is recording correctly. A Raspberry Pi setup also lets you backup your files to a memory drive and download data directly or over an internet connection.

As part of their Heritage Ability project, Living Options Devon recently hosted the UK’s first ever Deaf-led bat walk at the Love Parks event, in Cockington Park, Devon.
NHBS are delighted to have been able to loan them an Echo Meter Touch bat detector from Wildlife Acoustics, which allowed the attendants to view live sonograms on an iPad – whilst receiving further information in British Sign Language from the guide, Alasdair Grant.
This fantastic event was part of a whole day of activities helping to make heritage sites more accessible for disabled and Deaf people.
Alasdair, Deaf Alumni Programme Manager for Deaf Unity, who is working towards his bat license, led an inspiring bat walk which one participant said was “a memorable and unique experience”. The walk included watching soprano pipistrelles and lesser horseshoe bats exiting their roosts in outbuildings in Cockington Court, and common pipstrelles, serotine and noctule bats feeding in the park and lakes area.
The walk provided a unique opportunity for Deaf people to see and learn more about the lifestyle of our British bats and how to identify different species using bat detectors with visual sonograms rather than by sound. The Echo Meter Touch connects to an iPad to provide an excellent and very accessible visual display of bat calls in real time.
Living Options and Deaf Unity very much hope to run further bat walks in the future and would be delighted to advise other organisations and bat groups on how to lead bat walks for Deaf people.
The Heritage Ability Project supports heritage sites in South West England to improve accessibility for disabled people. Funded by the Heritage Lottery Fund, the project is currently piloting different approaches with partner sites including museums, country parks, nature reserves and historic houses.
Best bat detectors for bat walks
Echo Meter Touch
This tiny ultrasound module connects directly to your Apple device and lets you listen to bat calls in real time as well as viewing a live sonogram on your screen. Ideal for bat walk leaders, the Echo Meter Touch provides you with plenty of real time information to share with your group, as well as letting you record and classify calls so you can provide a later update of all species heard during the walk.
The Batscanner is one of the simplest bat detectors on the market – simply turn it on and listen. The device will automatically tune to the frequency of the bat call nearby and will display this frequency on the LCD screen whilst playing the sound back at an audible level.
The SSF Bat2 cleverly scans all frequencies simultaneously and will jump to the peak (loudest) frequency at the touch of a button. Pre-programme up to four fixed frequencies and view a small spectrogram of the received call. Ideal for beginner or seasoned bat walkers.
Magenta Bat 4 and 5
The Magenta Bat 4 and Magenta Bat 5 are our most popular detectors for beginners. Affordable to buy and simple to use, they convert the call produced by the bat into a sound which is easily heard through the speaker. Simply tune to the required frequency using the large dial on the front of the unit. The Bat 5 also has a digital display which makes tuning the detector even easier.
The bat survey season is just beginning and since our last update in November 2015 many of the new bat detectors have arrived in stock and we have received some customer feedback and updates on specifications from manufacturers. The total count of new bat detectors now stands at six – three passive full spectrum recorders from Elekon, two passive recorders in the Song Meter family from Wildlife Acoustics, and the handheld Anabat Walkabout from Titley Scientific.
We have had the Wildlife Acoustics SM4BAT FS in stock on and off now for the last few weeks (supplies have been limited) but we now have plenty on the shelves. We are really impressed with these units – they are smaller, lighter and easier to programme than the old Song Meters and have massively improved battery life (up to 45 nights for the FS and 70 nights for the ZC). They come in a strong lockable enclosure that can easily be chained to a tree and include a 3m microphone cable when purchased with the SMM-U1 microphone. The ZC units have not arrived yet but are expected in early April. The SM4BAT detectors also include an incredible three year warranty (excluding the microphones).
Wildlife Acoustics have also announced that they are phasing out the EM3+, the SMZC and the SM2BAT+, which are being replaced by the Echo Meter Touch, SM4BAT ZC and SM3BAT / SM4BAT respectively.
Elekon have now released three new passive bat detectors within the last few months which are based around the very highly regarded Batlogger M handheld bat detector. The Batlogger C is probably the highest specification bat detector on the market today – it has everything you would expect from a high end passive detector including programmable recording schedules, fully weatherproof enclosure, and high quality full spectrum recordings as well as many extras. These include optional sms and/or email messages reporting the status of the unit and the number of recordings made as well as the amount of power remaining. Furthermore, because the Batlogger C also has in-built GPS it can send you an alert if the unit is moved. A wide range of power options are available: a 50 hour rechargeable battery is included and there is space for a second. Mains power is also an option as is solar power which requires the addition of the Batlogger C solar panel. When used with two 50 hour batteries, just half a day of sun in every 10 days should be enough to keep the Batlogger C powered indefinitely.
Also from Elekon, the Batlogger A family – the A and the A+ are new miniaturised passive bat detectors. Both are programmable, are housed within a small weatherproof enclosure and include a Knowles FG microphone on a 2m extension cable. The Batlogger A will record for up to 30 hours on eight AA batteries (e.g. three 10 hour nights). The Batlogger A+ was created after a customer contacted Elekon to say that the Batlogger A looked perfect for installing up trees and in other inaccessible location but that ideally, the battery life should be longer. In response the team at Elekon quickly created the new Batlogger A+ which is slightly larger than the Batlogger A but includes the same rechargeable lithium ion battery used in the Batlogger C. This will power the A+ for up to 70 hours. Stock of both models are fairly limited so please contact us soon if you would like to place an order.
A few software glitches delayed the release of the Anabat Walkabout in 2015 but this incredible new bat detector has now been in stock for several months. The touch screen Android tablet based bat detector not only records any passing bats but also lets you view the sonogram in real time in both full spectrum and zero crossing formats. A GPS, lux-meter, thermometer and humidity sensor are all in-built so not only will each call be geo-tagged but you will also be able to collect the full range of environmental data for each transect without needing any additional tools. A fully charged unit will last for around eight hours. The Walkabout bundle will soon also include a copy of Analook Insight analysis software to allow you to view and analyse full spectrum and zero crossing recordings.

Bats of Britain and Europe is a new field guide highlighting the remarkable diversity of bat species regularly occurring in Europe. 45 species are described in detail, the pages are full of hundreds of colour photos of bats, and illustrative diagrams and tables, and there is substantial information on bat biology and ecology, tracking and detecting, and identification.
As authors Christian Dietz (long-established teacher, author and bat expert) and Andreas Kiefer (Research Associate at the University of Trier, Germany) say in the Foreword, this book represents the achievement of their “dream of continuing the field guide that introduced us both to bats” – Schober & Grimmberger 1987 /1998.
What is your background in studying and working with bats, and what makes them special for you?
Christian: I am working as a consultant in impact assessment studies mainly focused on bats and as a scientist in bat research. Bats are so special for me since they have evolved so many special adaptations to their nightly way of life and developed such a high biodiversity.
Andreas: I am a researcher in bat ecology and conservation. The diversity of bats is so big and in most species we are just barely scratching the surface on understanding them. And we need to know which species live where and why, otherwise conservation cannot be successful.
What was your first experience of seeing a bat in the wild?
Andreas: I started very late. When I was 20 I helped counting hibernating bats in slate mines, only half a year later I had my first own project. I searched for summer roosts of greater horseshoe bats in my home region but I found only grey long-eared bats. Up to now long-eareds are my favourite study objects.
Christian: As a child I found a brown long-eared bat injured by the neighbour’s cat and tried to care for it. Later I became fascinated with searching their roosts and practical conservation of hibernacula.
What areas of bat research are you currently focusing on?
Christian: As a consultant I am very interested in mitigation and monitoring of populations, and scientifically I am mostly engaged in studying the biodiversity and cryptic species in the Middle East and the Caucasus. Knowledge about the taxonomy and distribution of species is the important base for future conservation work.
Andreas: At the moment I am a researcher at Trier University. In my small bat group we currently work on the impact on wind energy on bat populations, the ecology and conservation of the Sardinian long-eared bat, and new methods for monitoring bat populations.
How are the British and European bat populations doing at the moment?
Andreas: Most of our bats species do fine, but we have signals that the grey long-eared bat is declining not only in Germany. The situation of Mehely’s horseshoe bat is more dramatic when you see it in a European context. Another species, the Sardinian long-eared bat which is endemic for Sardinia has fewer than 400 specimens left. Maybe this species will go extinct in the next years. Other species expand their range and come more to the North.
Christian: Some species like the pipistrelle bat do fine and are common and widespread, and even some rare bats like the lesser horseshoe bat seem to recover from former population crashes and slowly recolonise parts of their lost distribution. On the other hand some species still decline and may even face local extinction of populations. Examples are the grey long-eared bat and Mehely’s horseshoe bat, both specialists for preying on large moths in mosaic-like open habitats with grasslands, orchards and hedges. While the grey long-eared bat is still widely distributed, and the observed negative population trends and local extinctions still do not threaten the species as a whole, the situation with Mehely’s horseshoe bat is much more dramatic. It has already lost big parts of its European distribution and become extinct in some countries, while remaining populations are scattered and isolated. I am much afraid the species will become extinct since I have seen it disappearing in parts of Bulgaria already where I used to study it a decade ago.
If you could implement any policy change that you think would be of benefit to bats, what would it be?
Christian: Since the establishment of the European Natura 2000 network, bats get considerable protection and are taken into consideration in impact assessment and mitigation. However the implementation of these laws differs extremely between countries, and especially in the eastern parts of Europe nature protection is still difficult. There, changes in agriculture and massive habitat loss threaten some of the largest bat populations in Europe – on the other hand very expensive and sometimes ineffective compensation measures are done in western European countries. I think it would help a lot to concentrate some money from compensation to protect wonderful habitats and bats in Eastern Europe.
Andreas: Of course we need more money and projects for bat conservation, especially in Eastern Europe. And we need more sensitivity for useless compensations in Western Europe. But mainly we need a change in European agriculture politics. A better support for EU-subsidies for organic farming, less pesticides and a stop of land consumption would be helpful for bats and nature conservation overall.
The new book is a field guide to the 45 species of bat of Britain and Europe – who is the book aimed at, and what unique information will it provide for the reader?
Andreas: We hope that it is useful for professionals and beginners. For the first time, we give an overview to all European species and we show a key for the species identification of bat hairs from droppings.
Christian: We tried to give an up-to-date overview to the fascinating biodiversity of European bats and to give many ideas for practical conservation work.
You include newly described species – what can you tell us about these?
Christian: Bat taxonomy has seen big changes in the last decades, the biodiversity of European species has been much underestimated. We studied all newly discovered species in Europe from the Iberian Peninsula to Anatolia and on islands like Sardinia and Crete.
Andreas: Many new bat species had been identified in the past two decades, mainly with the help of DNA-sequencing. We tried to cover Europe and neighbouring areas and all European islands in the Mediterranean Sea.
If somebody is curious about studying bats, what advice would you give them to get started – apart from buying a copy of your book!?
Andreas: Join your local bat group! These people know what they do and they are happy when new bat friends will help them. Nothing is better than learning from experts and Britain has a lot of them.
Christian: Great Britain is famous for its many NGOs and local bat groups – so the best is to make contact to people being already engaged in bat research and conservation – they will help you.
