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.
Our full range of bat detectors can be found at www.nhbs.com
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.
If you would like any help, advice, or a short loan of one of our demo bat detectors please get in touch with our Wildlife Equipment Specialists on 01803 865913 or email@example.com.
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.
Five new bat detectors will become available in 2016 – two new models in the Song Meter family of bat detectors from Wildlife Acoustics, two new passive detectors from the Swiss manufacturer Elekon and the long anticipated Anabat Walkabout. Here we will give you a quick round-up of the key features of each new detector along with news of several detectors which will no longer be available. We will also introduce an exciting new BatCounter and camera trigger.
Wildlife Acoustics have brought out a new detector aimed squarely at the consultancy market – the SM4BAT. The SM4BAT is available in two versions – full spectrum (SM4BAT FS) and zero crossing (SM4BAT ZC). Both come in the same dark green plastic case (a bit like a Bushnell Natureview Trail Camera) which is weatherproof, slightly smaller and lighter than the SM2BAT+ and can be padlocked shut to prevent anyone tampering with the detector. Both use the SMM-U1 microphone which was designed originally for sale with the SM3BAT detector. They are also programmable and will record on a single channel for around 30 nights using four D-cell batteries.
Wildlife Acoustics have also announced that they are phasing out the EM3+ and the SMZC, which are being replaced by the Echo Meter Touch and the SM4BAT ZC respectively.
Elekon have released two new passive detectors within the last few months which are based around the very highly regarded Batlogger M handheld detector. The Batlogger C is probably the highest specification bat detector on the market – 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 is a miniaturised passive detector. It is programmable and will record for up to 30 hours on eight AA batteries (e.g. three 10 hour nights). The Batlogger A is housed within a small weatherproof enclosure and includes a Knowles FG microphone on a 2m extension cable.
The Anabat Walkabout, a handheld detector for transects and roost emergence surveys is also expected for the 2016 season. This touch screen Android tablet based 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 8 hours.
The BatCounter has the potential to be a very useful tool for both researchers and consultants. It uses a network of infrared beams to count, and log the direction of movement of bats moving through a detection area of 76 x 35cm (standard model) or 36 x 35cm (tree model). It has a GSM function that can send daily reports via text or email and will run for three days on eight AA batteries or for much longer periods using a 12V battery. You can also connect a Nikon or Canon DSLR camera and take pictures of the bats as they pass through the Batcounter.
UPDATE 7th MARCH 2016 – The Bat Survey Training Course has now been cancelled.
The use of passive monitoring to assess bat activity has important implications for how we work with the vast amounts of accumulated data, and automation now plays a crucial role in dealing with datasets which often contain thousands of recordings.
This bat survey training course has been designed to give you insights into the how-to of passive acoustic bat detection and call analysis, including its pitfalls. It will give you the skills to conduct passive acoustic bat surveys with confidence and to analyse your results in the most efficient and accurate way.
Topics covered will include: Why and where do we listen for bats, how to detect bats, signal analysis, bat call identification and working with large datasets. It will also include a short introduction to the Batcorder system.
The new SM4BAT range of passive bat detectors from Wildlife Acoustics was announced at the 2015 Bat Conservation Trust AGM.
The Full Spectrum (FS) version will allow you to record bat calls in 16-bit resolution at a sample rate of up to 500kHz on a single channel. The Zero Crossing (ZC) version is also single channel and will record zero crossing files. Both are weatherproof, come with a three year warranty and will record for up to 30 (10 hour) nights when powered with four high quality d-cell batteries.
Wildlife Acoustics have made some upgrades to their ultrasonic microphones this year – read on to understand what this means for you.
SM2BAT+ user An entirely new microphone is now available for SM2BAT+ users – the SMX-U1. This microphone is different in every respect from the original SMX-US microphone. The microphone element has been upgraded to a Knowles FG element which is more resistant to moisture but has greater sensitivity and a flatter frequency response so you will record more bats. The old foam windscreen has been replaced with a new and improved weatherproof membrane that will not hold water, and the microphone body is now slimmer and stronger. The old SMX-US microphone is still available in limited quantities if needed to provide continuity on a long term survey – please contact firstname.lastname@example.org to check availability before ordering.
SM3BAT+ or SMZC user The new SMM-U1 is electronically identical to the old SM3-U1 microphone and will give very similar results. The new model differs from the old version in two ways – the casing is now smaller and stronger and the old windscreen has been replaced by a new weatherproof membrane that will not hold water.
EM3+ (with optional external microphone) user
The EM3+ cannot be used with either of the new microphones. NHBS will continue to hold stock of the SMX-US and SMX-UTmicrophones for as long as possible for use as an external microphone for the EM3+ – pick up a spare if these are critical to your workflow.
Here’s Wildlife Acoustics microphone guide showing all models, compatibility and microphone type.
Lizzie Barker is a working ecological consultant, and the creator of gift and homeware design company, Creature Candy. This newly-launched enterprise produces quality British-made products featuring hand-drawn illustrations of wildlife. As well as raising profits for the Bat Conservation Trust, the Bumblebee Conservation Trust, and Butterfly Conservation, Creature Candy also intends to raise awareness around the conservation of our endangered and protected wildlife. We asked Lizzie how it all came about:
What are your background and current interests as an ecologist?
I studied Zoology between 2007 and 2010 at Aberystwyth University and graduated with a first degree. I then went on to work at Darwin Ecology in September 2010 as a consultant ecologist and have been there ever since. It’s a great company to work for and my job is very varied, although I specialise in bats. I hold a Natural England bat and great crested newt survey licence, but I also survey for dormice, badgers and reptiles. I love the spring and summer months so I can get outdoors and explore the English countryside for wildlife.
What’s the story behind Creature Candy?
I wanted to take more of a proactive role in wildlife conservation and raise money for the charities that I work so closely with as a consultant. Two years ago (whilst sitting on my sun lounger in Portugal) I came up with the idea of Creature Candy. I not only wanted to raise money for the charities, but also raise awareness of Britain’s declining & protected wildlife species, and to inspire people to take active roles in conservation. It was also incredibly important to me to change perceptions of bats, which is why my first design was a beautiful, charismatic brown long-eared bat illustrated in its true form, not a typical black silhouette with red eyes and fangs! It was also a priority to produce all our products with a “Made in England” stamp on them, which I think is very appealing in today’s market dominated by mass produced imported products.
How do you find the time to be an ecologist and an entrepreneur?
It’s a very hard balance to achieve. On a typical day, I switch off from the ecological consultancy world at 5pm, make myself a cup of tea and re-enter my office as the Director of Creature Candy. I then usually work for a few hours each night on marketing, processing orders and accounting, before spending some time with my husband before bed. It’s very important to find time for a social life and to relax, and I’m sometime guilty of over-working. However my husband is very supportive and I couldn’t manage the business without that support.
Can you tell us more about the artwork, and what’s to come for the range?
Our illustrations are hand drawn by my friend Jo Medlicott. Jo is a very talented artist and draws inspiration for our designs from photography and the natural world. Our next design is likely to be a red squirrel or a bird and we would like to introduce aprons and fine bone china jugs into the product range. The rest is top secret!
