The NHBS Harp Trap

The NHBS Harp Trap 

Earlier this year we were delighted to launch another exciting product manufactured here at our base in Devon. After a concerted period of design and manufacturing effort by our expert Workshop Team, followed by testing and review by ecological professionals, our NHBS Harp Trap was ready for production. The launch of our product into the wildlife equipment market signals the arrival of the only commercially produced harp trap in Europe. 

What is a Harp Trap? 

A harp trap provides an alternative bat survey method to mist netting or the use of bat detectors. They are particularly useful in situations where bats in flight can be channeled through a natural funnel such as above a water course, a cave or mine entrance or a clear area within a forest. 

Harp traps consist of a frame which is either freestanding or suspended, and supports two to four rows of nylon strings. The bats will fly into the nylon strands and then fall unharmed down into a collecting bag below. The catch bag is made from green cotton canvas that is water resistant and breathable and includes heavy duty clear plastic baffles to prevent the bats from escaping. Unlike mist nets, harp traps do not entangle the bats an it has been reported that they can be more effective for surveying bats, potentially capturing higher numbers of individuals. 

The NHBS Harp Trap

The new NHBS Harp Trap is a three-bank trap, meaning it has three rows of nylon line. Our trap has a catch area of approximately 4mand catch bag which is around 60cm deep.  It folds down neatly into a bespoke carry bag and weighs approximately 15kg-full specifications and dimensions are below. The trap takes two people around 10 minutes to assemble and stands on four sturdy, extendable legs and which can be arranged at the height that you need the trap to be. There is also the option to anchor the harp trap with guy ropes in windy conditions. The trap can also be adapted to be suspended if this is required. 

Our trap has a few innovative features designed to make assembly and disassembly easier. Firstly the strings are wrapped  around a winding mechanism which greatly reduces the stress and time-consuming act of sorting through tangled lines in the dark.

 

There is also an extension under the catch bag, which prevents the bats from flying underneath the trap and this doubles as protection for the component parts as it wraps around the disassembled trap when it is stored in its bag.

Testing 

As our harp trap evolved, prototypes were trialed and reviewed by ecology professionals; Professor Fiona Mathews of Sussex University and Neil Middleton of Batability. Their expertise and excellent feedback helped us develop our the harp trap to the point that it was now ready to go live. 

The team at NHBS have done an excellent job in coming up with a new and refreshing approach to harp trapping, which shows many innovative and useful design features.  When testing the equipment we were able to demonstrate that it was quicker/easier to assemble than competitor’s products.  We are happy to recommend this harp trap, and will be ordering one ourselves, to be used during our training courses and for bat-related research.

NHBS Guide to Bat Survey Equipment

Common Pipistrelle by Meneer Zjeroen on Flickr

With Spring around the corner and the bat survey season fast approaching, it is a great time to make sure you have everything ready for the busy months ahead. Over the winter we have been busy reviewing our current products, cataloging new products and even designing our own products. Here, we have picked out some exciting new products as well as some old favourites to take a look at.

The NHBS Harp Trap – Coming Soon!

Over the last few months, the NHBS manufacturing team have been working hard on developing the NHBS Harp Trap. We are currently in the process of testing and trialing our harp trap ready for its release in the coming months. Designed and built on-site at our workshop in Totnes, our three-bank harp trap will feature some innovative designs such as a winding line carrier and anti-tangling system that makes assembly and disassembly, easy and efficient. Made mostly from aluminium, the trap is surprisingly lightweight at just 15kg, whilst remaining sturdy and durable during use. The harp trap is 190cm long and has a catch area of about 4m². The catch bag is approximately 60cm deep and its entrance is about 39cm wide. When collapsed, the catch bag wraps around the disassembled frame and is held tightly with Velcro straps so that it can be neatly stored and carried in its bag. Initial feedback on its design and function has been very positive and we are excited to develop our design based upon suggestions from professional bat workers. Our standard trap will be a three bank, but if you would like a bespoke two or four bank trap, please contact us so that we can discuss your requirements.

BTHK Tree-Roost Net

Based on the design by Henry Andrews from the Bat Tree Habitat Key (BTHK) project, the BTHK Tree-Roost net is uniquely designed for trapping bats as they emerge from tree roost sites. The net is set up against a roost site prior to dusk so that it will catch any bats that emerge, keeping them safely in the bag ready for identification, measuring and ringing. The diamond shape of the net head can pivot and collapse inwards to ensure that the net fits flush against any tree, making it safer for bats and easier for surveyors. The net bag is made from fine woven nylon mesh that is soft and will not damage the delicate wings or feet of bats. The net bag can be easily removed for cleaning and features a clear plastic rim that fits around the collar and prevents bats from climbing up and out of the net when it is in place. The length of the handle is 4 meters (breaks down into 3 sections for ease of transport) and the depth of the bag is 1 metre. You may also be interested in the book Bat Roosts in Trees which is a guide to finding tree roosts.

Anabat Scout – Coming Soon!

The Anabat Scout is the latest bat detector by Titley Scientific. Due for release this March, the Scout is designed with UK and European bat biologists in mind and is tailored for active bat surveying. It can record both full spectrum and zero crossing files and stores them on a SD card with every file geo-tagged. The Scout has heterodyne, auto-heterodyne and frequency division audio that can be played through earphones or its own built-in speaker. The in/out bat counter is ideal for emergence surveys and will automatically timestamp and geo-tag every count. The small OLED screen displays crucial information without being too bright or distracting and the Anabat Scout will be compatible with Anabat’s free Anabat Insight software for viewing and analysing your data. Easy to use and versatile, this new detector is set to become popular with bat ecologists who are looking for an active survey detector.

Elekon Batlogger M

The Elekon Batlogger M is great for active surveying and full spectrum recording. The weatherproof FG Knowles microphone has a range of 10–150kHz and can record in 16-bit full spectrum. The Batlogger M also logs the GPS coordinates (via an integrated GPS receiver), and environmental temperature at the time of recording. Different recording settings (scheduled, permanent, or triggered), and different trigger thresholds (for call identification) can be set up and the device comes with its own powerful but user-friendly call analysis software package

Echo Meter Touch 2 Pro

The Echo Meter Touch 2 lets you record, listen to, and identify bat calls in real-time on your iOS or Android device. All you need is your Android or Apple device (see the nhbs.com website for compatible models), your Echo Meter Touch 2 Pro, and the Echo Meter Touch App which is a free download from the iTunes Store or Google Play Store. When plugged in, the Echo Meter Touch 2 enables you to listen to bats in real time, view live sonograms in full colour, record onto your device and identify calls to species level in seconds. If your device has GPS functionality, the Echo Meter Touch will also log the recording location and path of the recording session. There are two versions available in both an iOS version and Android version. Both versions allow you to listen to calls in real time expansion and heterodyne and you can playback in real time expansion, heterodyne or time expansion modes. The trigger sensitivity and sample rate are adjustable and three gain settings allowing users to optimise their detector to their target bat species and ambient conditions.

SM4BAT FS

The SM4BAT FS is a full spectrum detector for passive surveying use. Robust and weatherproof, it will record 16-bit full spectrum calls and can store up to 512GB of data. A versatile scheduling function allows you to set when you want to record and the battery can last up to 450 hours. The SM4BAT FS is easy to fit to a tree or post and is compatible with a variety of accessories such as GPS unit and microphone extension cables. The SMM-U2 ultrasonic microphone is available with the SM4BAT FS and is a highly sensitive microphone that produces high quality, low noise bat recordings over long distances. Easy to set up and producing detailed call recordings for analysis, the SM4BAT FS is ideal for unattended use in the field.

Anabat Swift

The Anabat Swift from Titley Scientific is based on the excellent design of the Anabat Express, but has the advantage of recording in full-spectrum, as well as zero crossing. Users can choose between sample rates of 320 or 500kHz and data is saved onto an SD card. Two SD card slots are available, allowing you to save more bat calls without changing cards. The Swift also has a built-in GPS receiver that automatically sets the clock, calculates sunset and sunrise times and records the location of the device. It will also record automatically from sunrise to sunset every night (based on GPS coordinates) as one of the automatic recording settings.

BatLure

The BatLure can be used as a lure to improve catch rates of bats for survey or research, to attract bats to new artificial roosts such as bat boxes or constructed hibernacula, with bat detectors at training events or prior to bat walks and for calibration of bat detectors. The Batlure can playback sounds with frequencies of up to 100kHz and is capable of playing both real time and time expanded recordings of bat vocalisations. It is very compact and robust and has a tripod attachment mount, making it easy to set-up in your desired location. It plays sounds from an SD card which is supplied complete with several pre-loaded recordings. Users can also add their own recordings onto the card.

Ecotone Ultra Thin Series M mist net for bats

The Ecotone Ultra Thin Series M is ideal for catching bats and is available in 2 mesh sizes. Both are made from nylon (0.8mm monofilament) and have 4 shelves. Available in lengths from 3m to 21m, you can pick the mesh size and length that best suits your survey and situation.

 

Explorer Premium Digital Endoscope Camera

The Explorer Premium Digital Endoscope is lightweight and easy to operate. It can record still images or video on to a microSD / microSDHC card (not included). The screen can be detached whilst the camera is in operation and viewed up to 10m away. The camera head has a diameter of 9mm and the cable is 91cm long, giving easy access to nest boxes, burrows, nests, crevices etc. Lighting levels can be adjusted to minimise disturbance to animals.

International Bat Weekend 2018

International Bat Weekend (formerly European Bat Night) has been celebrated since 1997 in 30 countries around the world. This two-day event is a fantastic chance for conservation groups and NGOs to raise the profile of bats and to educate the public about these fascinating, yet often misunderstood, nocturnal creatures. Events include presentations, exhibitions and bat walks which, in 2018, will be held over the weekend of the 25th-26th August.

An evening walk with a bat detector provides a great glimpse into the mysterious world of bats.

In the UK, events are organised by the Bat Conservation Trust and you can search for things happening near to you on the events section of their website. International events can be viewed on the Eurobats website.

The Bat Conservation Trust has also put together a helpful handout with lots of ideas for organising your own bat-related event. Perhaps you could even raise some money for the Trust to help them to continue the valuable work that they carry out to help bats in the UK. If you decide to hold an event, don’t forget to let them know so they can feature it on their website!

You might also like to check out our handy guide to find out more about how you can help your local bats.

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.

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
