New Bat Detectors for Spring 2017

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.

Anabat Swift

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.

Batcorder Mini

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.

Batcorder GSM

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.

What’s new for 2016 – Bat detector news

Elekon Batlogger C
Elekon Batlogger C

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.

Song Meter SM4BAT
Song Meter SM4BAT

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 TouchSM4BAT ZC and SM3BAT / SM4BAT respectively.

Elekon Batlogger C
Elekon Batlogger C

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.

Elekon Batlogger A+
Elekon Batlogger A+

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.

Anabat Walkabout
Anabat Walkabout

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 customer.services@nhbs.com.

 

What’s new for 2016 – Bat detector news

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.

SM4BAT
The SM4BAT is available in a full spectrum or zero crossing version.

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.

Batlogger C and Batlogger A
The Batlogger C (left) and Batlogger A (right) offer solutions for a variety of bat survey situations.

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.

Anabat Walkabout
The Android based Anabat Walkabout allows you to view live sonograms in the field.

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.

BatCounter
The BatCounter will log the number of bats passing through as well as the direction of their movement.

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 for Wildlife Acoustics bat detector users

Wildlife Acoustics have made some upgrades to their ultrasonic microphones this year – read on to understand what this means for you.

SMX-U1

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 customer.services@nhbs.com to check availability before ordering.

SMM-U1

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-UT microphones 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.

Ecology gifts raise money for key UK conservation charities

Creature Candy mugsLizzie 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.

Creature Candy printsWhat’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!Creature Candy moth tea towel

Getting started with the SM2BAT+ bat detector

SM2BAT+The Wildlife Acoustics Song Meter SM2BAT+ is a passive ultrasound recorder that can be left out in the field for long periods of time to record ultrasound at frequencies of up to 192 kHz. The SM2BAT+ comes packaged in a plain green weatherproof box making it easy to position discretely without the need for expensive or time consuming efforts to weatherproof/camouflage it. Setting a bat detector up for passive monitoring can be a slightly daunting experience for the first time user so we have produced an annotated internal diagram (see below right – click the image to enlarge) and this blog post describing our experiences getting started with the SM2BAT+. Despite feeling a little scared at Inside the SM2BAT+the sight of circuit boards I am pleased to report that I found the SM2BAT+ to be very user friendly – read on for our idiot’s guide to setting up an SM2BAT+.

Getting started

The first thing you will need to do is insert four D-Cell batteries into the slots. A number of variables affect battery life including the quality/type of the battery, temperature, and the recording mode. The manual produced by Wildlife Acoustics suggests that if high quality Alkaline D-Cells are used at 20oC then you should get 130 hours recording time at 192 kHz mono and 100 hours recording time at 192 kHz stereo or 384 kHz mono when using in WAV mode and over 300 hours of recording time when using ZCA mode.

Next you will need to insert an SDHC card into one of the Flash Card Slots. Wildlife Acoustics recommend using good quality SDHC Class 4 or Class 6 cards and a single 32GB card should easily last a minimum of 2 weeks.

How to programme your SM2BAT+

Now it is time to programme your SM2BAT+. Setting up a simple schedule is very easy, switch the unit on by pressing the WAKE/EXIT button. Once it has woken up you will be able to see whether your SDHC card has been accepted and how much spare memory is available. To programme your unit press the SELECT button to see the menu; then to scroll through the menu options press the UP and DOWN buttons, press BACK to move back up a level, and press SELECT to move left and/or toggle through a list of options.

Below left shows a schematic (click to enlarge) of the Song Meter Main Menu and includes the settings I used for a trial run of the SM2BAT+. The first page of the menu includes three options – Schedule, Settings and Utilities. Setting the schedule could not be easier, press SELECT when the cursor is flashing next to Schedule, then press SELECT again, update the time using the UP and DOWN buttons then press SELECT again to keep moving to the left filling in the details as you go. You will see that I have set our SM2BAT+ to come on at 20:30 and record for 10 hours.

SM2BAT+ SchematicPress BACK to come out of the Schedule menu and then DOWN to move to Settings, then SELECT again to enter the Settings menu. For a quick test of the unit you will need to set the time and date using the UP, DOWN, SELECT, and BACK buttons as before. Finally select AUDIO to check the recording settings. In my test run I opted for a Sample rate of 384000 (384 kHz) because we have lesser horseshoe bats in the Totnes area. This is because the maximum frequency recorded is equal to half the sample rate – consequently, at a sample rate of 384 kHz the SM2BAT+ will record ultrasound at frequencies up to 192 kHz on one channel (perfect for lesser horseshoes that echolocate at around 110 kHz). If you want to use both channels (i.e. two microphones) you have to record at a maximum sample rate of 192 kHz. Although you may miss lesser horseshoe bats the big advantage of using both channels is that you can separate the microphones (using extension cables – available from NHBS) by up to 100m, effectively doubling the number of bat detectors you own for the price of a couple of cables. Alternatively you can separate the microphones by 10-20m to measure flight directionality along a linear feature.

Next you need to select which channel to record on. Under Channels I selected Mono-L to record from the left hand microphone input. For Compression I selected Off which means that the SM2BAT+ is in trigger mode and records individual WAV files for each trigger.  Analook users may prefer to use the ZCA option which records individual ZCA files for each trigger. Alternatively, some users may prefer the WAC0 option which produces a continuous compressed WAC file for the duration of the recording period (actually the files are size limited so I found that 1hr 33min chunks are produced). That’s it… all you need to do now is take your SM2BAT+ to your field site.

Field set-up

Once at your field site check the settings and do a test recording. To do this plug some headphones into the headphone jack and start recording by pressing both the UP and DOWN buttons simultaneously. Once the recording has started press SELECT to view the channels and then make some ultrasound by eg. tapping your fingers and thumb together or rattling some keys. If all is well then put your unit back to sleep, seal the weatherproof enclosure (don’t forget to take a screwdriver with you) and plug your microphone in to the left hand microphone input (using your extension cable makes hiding the unit much easier). It is worth remembering that the indicator LED is visible when the lid is on so make sure this cannot be seen by passers-by.

Data analysis

Downloading the data is also easy – simply remove the SDHC card and place it into an SD card reader. To analyse the data I used Pettersson’s BatSound v4.12. My WAV files opened immediately and I used the Close, open, next button to scroll quickly through the files so the analysis was quick and painless. On my first night I recorded soprano pipistrelle and greater horseshoe bats in the centre of Totnes.

Triple Chamber Bat Box available from NHBS for the first time this autumn

Triple Chamber Bat BoxIntroducing the Triple Chamber Bat Box

 

NHBS’s new Triple Chamber Bat Box is available for the first time this autumn. The new bat box has three large chambers providing its inhabitants with a huge living area (compared with most other wooden bat boxes). Consequently, they are particularly well-suited to large colonies, including maternity colonies. Most crevice-dwelling bat species are likely to be attracted including Pipistrelles, Brown long-eared bats, and Daubentons. Species which may sometimes use these boxes include other Myotis species and Noctules.

Triple Chamber Bat Box interiorThe boxes are very deep, providing the bats with a stable draught-free environment and plenty of space for individuals to cluster together or disperse, and for the sexes to mingle or separate. Triple chamber boxes have proved to be a success in the U.S. where it is thought that the extra space provided gives bats the room to interact more normally. The boxes open at the top and are 60 cm high with a small aperture at the base of the box for bats to enter and exit. They are narrow (14 cm) and can easily be hung on both trees and buildings. The Triple Chamber Bat Box is constructed from European Redwood harvested from a sustainably managed forest.
