This week a small group of us took a trip to Dartmoor to try and catch a glimpse of Nightjars. As well as getting a chance to see one of the UK’s most elusive birds this was also a great opportunity to field test some of the equipment we sell.
Nightjars are cryptic, nocturnal birds that arrive in the UK in May to breed before migrating south in September. For the best chance to see these amazing creatures you need to head to heathland, moorland or open woodland on a warm, still evening. If you are early enough in the season you may also get a chance to see the males displaying, showcasing a repertoire of wing claps and churring.
So what did we pack for an evening of Nightjar watching? Our kit bag is below:

At the site we visited we were lucky enough to see 2-3 males displaying and, despite the low light conditions, the binoculars were extremely useful for picking out individuals on branches. We were also able to capture some great audio recordings with the SM4 Acoustic recorder which we deployed for a few hours. A sample audio clip from the SM4 can be found below. The Tascam allowed us to record as we watched the nightjars displaying, giving us the chance to record all parts of the display. During the walk back we started up a couple of the bat detectors and were greeted by a few different species including noctules and pipistrelles.
A parabolic microphone (Telinga PRO-X or Hi-Sound Mono Parabolic Microphone) would have been extremely useful for getting some high-quality recordings. Although the Tascam worked well by itself, a highly directional parabolic microphone would have allowed us to get higher quality recordings and reduce background noise.
The binoculars performed fairly well given the low light conditions but on the next trip I would be really interested in testing a night vision scope such as the Pulsar Digiforce 860RT as a way to try and spot perched nightjars later into the evening.
We had a great evening observing these fascinating birds and I highly recommend it. Nightjar populations have been recovering recently but they are still an amber listed species. They are highly sensitive to habitat change and, since they nest on the ground, are particularly vulnerable to disturbance from people and dogs. So if you decide to go and observe the Nightjars displaying this summer please be mindful, stick to paths and keep dogs on leads. More information on Nightjar conservation and identification can be found on the RSPB website.
At NHBS, all members of staff have the opportunity to partake in conservation volunteering days as part of the company’s philanthropic initiative to carry out nature conservation locally. As part of this initiative, I recently chose to volunteer at an event for a cause that is close to my heart nearby in Totnes.
On Friday 8th June, I volunteered at a Farm and Wildlife Fayre run by Ambios, an organisation that provides education and volunteering opportunities in nature conservation in the UK and abroad. Set in the beautiful Sharpham Estate, with the river Dart and rolling hills surrounding the farm, it was the perfect setting to engage others in nature conservation. This place is special to me, as this is where my initial nature conservation training began before I joined NHBS in 2017. Below is a video of the Wildlife Fayre filmed by Ross Gill of Fresh Ground Films.
At the Wildlife Fayre I worked alongside conservation volunteers, knowledgeable experts in the field and the charity, United Response, who provide a range of support services for individuals with physical and learning difficulties. The aim of the event was to get a wider audience of people involved in nature conservation by allowing them to take part in accessible activities that help individuals to get up-close and personal with local wildlife. More than 200 children and young adults from special needs schools and colleges attended, in addition to young families from the local area.
Engaging and educational activities drew in crowds, including bug hunts, bird box making, forest school sessions, green woodworking and plant identification. The air was filled with excitement as children and adults alike rushed around with their newly carved spatulas and bird boxes. Footsteps hurried as groups rushed between activities with freshly picked produce from the farm in their hands.
The farm office was transformed into a wildlife information hub, which hosted an array of interesting finds. Through microscopes you were transported into another world where you could view bumblebees and Garden Chafer Beetles at close range.
Tanks held Palmate Newts hiding amongst curtains of pond weed and field guides lay next to plaster-cast footprints of creatures who had visited the farm. In one corner, a table was covered with flora found locally for anyone wishing to test their plant identification skills. In another, an array of uncommonly seen finds were lined up including the skulls of animals and tightly woven dormouse nests.
Something that really drew me in were the screens in the wildlife information hub which displayed stories of the wild residents of Sharpham, including nest box inhabitants and various small mammals. You could watch a timeline of Blue Tits building their nest and sitting on eggs. Later you saw the chicks being fed, strengthening their wings and finally fledging!
My responsibilities whilst volunteering at the event revolved around providing support and an extra pair of hands. I helped groups to move between activities and demonstrated how to use tools and equipment such as nets and pooters. At NHBS I work as a Wildlife Equipment Specialist, so it was great to be able to show others first-hand how to use the equipment that we have access to every day. It was lovely to see how excited the children got about using the equipment to get closer to nature.
The Farm and Wildlife Fayre was a fantastic success! The event proved to be a brilliant way of captivating young minds and introducing them to the natural world. By partaking in accessible activities, each person felt confident enough to try something new and learnt a great deal along the way.
Ambios Director and Farm Manager said,
“Our farm and wildlife fayre was a huge success – we are delighted! We had nearly 200 people over the day, from all walks of life experiencing what we do at lower sharpham farm, and getting up close and personal with wildlife as well as getting to know our farm animals. Our farming practice aims to prioritise wildlife, and we are delighted to share our work and our story with a wide audience. Our next event will be a barn dance in the late summer, so watch this space!”
It was great to be involved and I love to think that if this event has inspired just one person to appreciate and protect nature a little further, then it was all worth it!
Stay tuned for more volunteer event posts from my colleagues at NHBS as they embark on their own conservation volunteering days.

NHBS equipment team member Johnny Mitchell, developed a keen interest in sound design and field recording whilst studying contemporary music. He continues to be fascinated by the technical challenges of field recording and its use for ecologists. With the recent publication of Joeri Bruyninckx’s Listening In The Field, interest around this subject continues to grow, so Johnny has provided some thoughts about the art of wildlife sound recording along with some excellent book recommendations.
‘In its broadest sense, field recording is the act of capturing sound outside of a traditional recording studio environment.
We live, it seems, in a culture that values vision and image above all other senses. In our increasingly noisy society, and as the cacophony of human-induced noise increases around us, it can be easy to forget the value of simply listening as a way to engage with the natural world.
One of the most evocative and earliest examples of field recording can be can found in the BBC recordings of Cellist Beatrice Harrison who, whilst playing in the garden at her home in Oxted, Surrey, noticed that the nightingales in the woods around her responded to, and even echoed, the notes of her cello. Broadcast just two years after the Birth of BBC radio in the early 1920’s, it was the first time that wildlife had been broadcast over live radio in the UK, and it proved to be so popular that the recordings were repeated every spring for the following 12 years.
Advances in high-quality, portable audio equipment have led to a fascinating cross-pollination between artists, musicians and scientists. In his new book, Listening in the Field, Joeri Bruyninckx traces the development of field recording and its use in field ornithology. Drawing on expertise from experimental music to serious science, it provides a thorough and wide-ranging investigation into the power of sound and listening.
In The Great Animal Orchestra, Krause, a former musician/composer and now leading expert in soundscape ecology, details his experiences in over 40 years of collecting wild soundscapes and explores what these can tell us about the health of various biomes.
Wild Soundscapes offers the reader both a philosophical guide and practical handbook- it is a highly readable and invaluable guide into the many techniques and different types of audio equipment available to anyone making their first forays into the field.
Krause encourages us to take a widescreen view of the soundscape as a whole rather than focusing on single species. Whilst listening to his recorded sounds and visualising them using spectograms, Krause also developed his ‘niche hypothesis’ – discovering that many creatures have developed temporal and frequency niches in which to communicate. What we would perceive as a chaotic web of sound is, he argues, highly ordered, and organisms in a soundscape structure their vocalisations over both frequency and time.
Tragically, over half of the soundscapes in Krause’s archive have either been dramatically altered by human activity or silenced altogether. However, as interest and technology advance it is fair to say that we are coming to understand and value the natural soundscape around us and our effect upon it’.
Field Recording Equipment
At NHBS you will find a great range of microphones, recorders and accessories for field recording.
The UK is home to seven native species of amphibian. Over the winter, these frogs, toads and newts have all been hibernating, but it will soon be time for them to venture out to their breeding ponds and pools. If you’re lucky, you will be able to spot them when you’re out and about.
In this blogpost we will provide you with some of the key characteristics of each species which will help you to identify exactly what you’re looking at. For those of you who are keen to find out more, we have also provided a list of field and identification guides at the bottom of the page.
Newts are members of the salamander family and have a lizard-like body shape. They are semi-aquatic, spending part of the year on land, returning to the water in spring to breed. Eggs are laid in the water where they hatch into tadpoles and then proceed to develop front and back legs, along with gills for breathing. They leave the water in late summer once their gills have been lost.
The three species of newt which are native to the UK are the Smooth Newt (Lissotriton vulgaris), the Palmate Newt (Lissotriton helveticus) and the Great Crested Newt (Triturus cristatus).
• Size: Grows to around 10-11cm in length. • Colour: Males brown/olive; females light brown. Belly is usually yellowy orange with black spots. The throat is pale with darker spots. • Skin Texture: Smooth • Habitat: Spring to early summer in ponds and pools (frequently found in garden ponds). Late summer under logs and stones near to water. • Other notes: The male has a wavy back crest during the breeding season.
• Size: Grows to around 7-11cm; slightly smaller than the smooth newt. • Colour: Males olive brown; females yellowish brown. The throat is white/pale pink and does not have spots or speckling. The eye has a dark stripe running horizontally through it. • Skin Texture: Smooth • Habitat: During the breeding season (early March to late May) in shallow ponds, often in heathland bogs. During summer in woodland, ditches and gardens near to water. • Other notes: During the breeding season, the male palmate newt has a ridge running along its back and a tail which ends in a filament. Its back feet are also webbed.
Great Crested Newt
• Size: Up to 15cm in length. Females may be even larger than this. • Colour: Dark brown or black with white/silver dots on sides. Underside is orange with black spots. Pale throat. • Skin Texture: Warty • Habitat: March to May in deep ponds with vegetation. Great crested newts often range further than smooth or palmate newts during the summer and can be found in gardens, ditches and woodland. • Other notes: The male has a very distinctive crest during the breeding season which is broken at the point where the tail meets the body. The crest also has a silver stripe.
Frogs are short-bodied, tailless amphibians that largely lay their eggs in water. These eggs hatch into aquatic larvae, known as tadpoles, before metamorphosing into froglets and then adults.
There are two native species of frog in the UK: the Common Frog (Rana temporaria) and the Pool Frog (Pelophylax lessonae).
• Size: Adults grow to 6-9cm in length. • Colour: Olive green to yellow-brown. Usually spotty or stripy with dark patches behind the eyes and darker barring on hind legs. • Skin Texture: Smooth and moist. • Habitat: From late February to early October in all sorts of ponds and pools. Common in gardens. • Other notes: Moves by hopping. Common frogspawn is gelatinous with black embryos and tadpoles are initially black but turn speckled brown. (This is a useful way of distinguishing them from toad tadpoles, which remain dark until development).
• Size: Adults grow to 6-9cm in length. • Colour: Usually brown with dark spots. Light yellow back stripe. • Skin Texture: Smooth and moist. • Habitat: Currently only present in localised spots in East Anglia. • Other notes: Males have prominent vocal sacks on the side of the mouth.
Toads are characterised by dry-looking, warty skin and short legs. They usually move via a lumbering walk, as opposed to the hopping motion used by frogs. As with frogs, most toads lay their eggs in water. These hatch into tadpoles before growing legs and metamorphosing into the adult form.
Within the UK there are two native species of toad: the Common Toad (Bufo bufo) and the Natterjack Toad (Epidalea calamita).
• Size: Females grow up to 13cm whilst males are smaller and usually reach only 8cm. • Colour: Brown to grey-green. Paler on the underside. • Skin Texture: Dry-looking and warty. • Habitat: From late February in damp, shady spots near to breeding ponds. During the summer in woodlands, gardens and fields. • Other notes: The common toad has amber eyes with a horizontal pupil. Moves with a lumbering walk or small hop. Eggs are laid in strings in a double row. Upon hatching the tadpoles are dark and, unlike frog tadpoles, remain so until they develop.
• Size: Females grow up to 8cm whilst males are slightly smaller. • Colour: Pale brown/green, often with brightly coloured red or yellow warts. Yellow stripe down the spine. • Skin Texture: Dry-looking and warty. • Habitat: Coastal dunes and lowland heath, often in open, unshaded habitats. The natterjack toad is very rare in the UK. • Other notes: The natterjack toad has amber eyes with a horizontal pupil. Moves with a running motion, rather than hopping. Lays strings of eggs in a single row.
Amphibians and Reptiles
A comprehensive guide to the native and non-native species of amphibian and reptile found in the British Isles. Professor Trevor Beebee covers the biology, ecology, conservation and identification of the British herpetofauna, and provides keys for the identification of adult and immature specimens as well as eggs, larvae and metamorphs.
Britain’s Reptiles and Amphibians
This detailed guide to the reptiles and amphibians of Britain, Ireland and the Channel Islands has been produced with the aim of inspiring an increased level of interest in these exciting and fascinating animals. It is designed to help anyone who finds a lizard, snake, turtle, tortoise, terrapin, frog, toad or newt to identify it with confidence.
A Guide to the Reptiles and Amphibians of Britain and Ireland
This laminated pamphlet is produced by the Field Studies Council and covers the 13 species of non-marine reptile and amphibian which breed in Britain, as well as the five species which breed in Ireland. These include frogs, toads, newts, snakes and lizards.
Field Guide to the Amphibians and Reptiles of Britain and Europe
This excellent field guide covers a total of 219 species, with a focus on identification and geographical variation. The species text also covers distribution, habitat and behaviour. Superb colour illustrations by talented artist Ilian Velikov depict every species.
The Amphibians and Reptiles of Scotland
This book is designed to be an interesting and informative guide to the amphibians and reptiles that are found in the wild in Scotland. The authors have focused on those species native to Scotland, plus those which are non-native but are breeding in the wild.
Earlier this year we were contacted by the Zoological Society of London (ZSL) who were interested in working with us to make a bespoke aquatic survey net.
Their specifications required the net to have a square frame with a four point bridle and connections for a flow meter. It also needed to have a diving vane which would ensure that it could be towed stably at a set depth, and a screw on cod end with a bag made from 53µm and 250µm mesh. Following these guidelines, our engineer and seamstress got to work and within a couple of weeks a detailed specification was agreed. The nets were then manufactured and two were sent to ZSL in February.
Several months later we were delighted to receive some photos from Anna Cucknell, who manages ZSL’s work on fish conservation in the Thames, showing the nets in use.
“It was great to work with NHBS, who listened to our specific needs to design bespoke sampling nets for juvenile fish, and used their experience to adapt our designs to fit our needs. Our juvenile fish surveys on the Thames are the first of their kind, in scale and resolution and we hope the results from which will be applicable in the Thames and further afield to help drive conservation and better management of our estuaries for all fish species”. Anna Cucknell, Thames Project Manager, Zoological Society of London
Fish Conservation in the Thames
The nets we made for ZSL are being used for an ongoing project to monitor the use of the Thames by juvenile fish.
The Tidal Thames is home to more than 100 fish species including many that are commercially important such as Dover sole and European seabass. It also provides critically important habitat for rarer species, including European smelt and European eel.
Like most estuaries, the Thames provides invaluable spawning, migratory and nursery grounds but, despite this, the region is poorly studied. The ZSL project hopes to remedy this by providing essential information about the health of fish populations in the estuary, and to assess how these are affected by water quality and local developments.
The project, funded by Tideway, involves both boat-based and foreshore sampling and, excitingly, also provides an opportunity for volunteers to get involved via its citizen science scheme. Volunteers can help with a variety of tasks including measuring, identifying and counting the fish.
For more information about the Tidal Thames fish conservation project, head over to the ZSL website.
Foraging was my first introduction to the natural world.
While sounding slightly trite, this statement is non-the-less true. I grew up in a town, like most of us do, and before I started foraging for nothing more exciting than blackberries I didn’t pay much attention to ‘nature.’
So, what did foraging teach me about the natural world that climbing trees and making dens couldn’t? Simply the realisation that blossoms provide pollen to pollinators such as bees, enabling the trees and shrubs to produce fruit. Eureka! So, that’s what bees are for! Then there are the seasons: not just for influencing the contents of the wardrobe, seasons were the on/off or pause for everything. I began to get excited, I discovered wild mushrooms, I was twelve and I’ve been foraging ever since.
Are we foraging too much?
Foraging is quite a controversial issue. There are lots of passionate arguments for and against it and a quick browse of the subject on the internet will tell you more. Like many, I am concerned that professional foragers can damage the natural environment. It seems logical that stripping out all the mushrooms or sea kale from a small area will damage that environment in some way. Surely foragers just need to abide by good practice, it’s the practitioner’s actions not the practice itself that can cause problems. Then there is the notion of sustaining oneself with ‘wild food.’ At best this notion is romantic, more likely delusional. My love of foraging is wholly based on getting outdoors and learning about nature – foraging is not an alternative to going to the shops.
Is it dangerous?
Firstly, you do need a book, especially if you are foraging for mushrooms; mis-identification can and does have dire consequences. You need to be careful and acquire knowledge with experience. You discover a sought-after Boletus edulis, considered the king of all mushrooms and totally delicious (I can vouch that they are). However, before you enjoy your gourmet mushroom, make sure the stem doesn’t turn blue when cut, otherwise you’re eating Boletus erythropus and are in for an unpleasant stomach ache. More serious consequences can occur from eating the morbidly named destroying angel, Amanita bisporigera, or the death cap, Amanita phalloides. Please be very familiar with both before you eat wild mushrooms. A book will suffice as a identification checklist, but the best way is to find a specimen and take note of all its pertinent features, cross-referencing with more than one book if possible. Once you can confidently identify a destroying angel or a death cap, you can be confident the mushroom you are planning to eat isn’t one of them.
Away from the more well documented mushroom poisoning, you might find yourself spending your evening taking the tiny stalks out of every single elderberry in the clusters you’ve picked – the leaves, twigs, branches, stalks, seeds, and roots of Sambucus plants can contain a cyanidin glycoside, so it’s best to be safe. Oh, and you need to cook the berries too. You don’t have to take risks though, as the Woodland Trust has planted many community orchards in towns, resulting in enough blackberry and apple jam to last you a whole year.
Which books should I use?
There are lots of books available and we have compiled a short list here for you to browse. In no particular order, the following contain interesting and practical information on foraging:
Being outside in all weathers, learning about nature, connecting with the natural world, acquiring more and more knowledge and experience: whether you are in town, country or even the city there will be plants growing everywhere that you can eat. It’s fun, slightly dangerous and can give children their first and lasting experience of connecting with nature. It did that for me and has stayed, and will stay with me all my life.
The accumulation of stacks of pallets is an unavoidable part of working in a fast paced and varied retail environment. So when we were contacted by Keith Grant from the Slapton Ringing Group to ask if they could take some off our hands, we were both delighted to agree and eager to learn about the site where they would be put to use.
The Slapton Ringing Group is based at the Slapton Ley National Nature Reserve. This beautiful site is located on the south coast of Devon and contains the largest lake in the south west, separated from the sea by just a narrow shingle bar. Its location, together with the unique habitat conditions, makes it an extremely important place for local and migrating bird populations.
The Slapton Ringing Group have been surveying birds at Slapton Ley since the 1960s, and for the last six years the site has been designated as a BTO Constant Effort Survey (CES) Site.
A regular rotation of willow cutting is undertaken at the site, which maintains the vegetation and helps to avoid major changes in species composition. A carefully constructed pallet walkway allows access to the ringing rides for the volunteers that meet here regularly throughout the ringing season.
The pallets salvaged from NHBS were used to replace old ones which have an obviously limited lifespan due to the constantly wet conditions. It is a pleasure to know that some of our “waste” is being used to support such a fantastic and long-running project.
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.
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 firstname.lastname@example.org.
The newt survey season is almost upon us and NHBS has been working hard through the winter to increase the range and quality of newt survey products we sell. Read on for a selection of our most exciting new products and news of some old favourites.
Newt survey nets and bags
We now sell a specially designed newt net with a 300mm wide head, 300mm deep bag of soft 2mm mesh fabric, and 1.2 metre wooden handle. The net is attached over the frame unlike our standard professional pond nets to ensure that newts cannot get caught between the frame and bag.
Dewsbury Newt Trap
NHBS is the exclusive distributor of the Dewsbury Newt Trap. The Dewsbury trap is safer for both newts and surveyors. Fewer traps are required per pond and the clever design allows the newt to either seek shelter at the bottom of the water column or rise to the surface to breathe even if the water level within the pond changes during the trapping period.
We also manufacture the traditional bottle traps. This is not a fun job so allow us to save you a lot of time and effort with our standard 2l bottles sold with the head cut off and inverted. We also sell bamboo canes for securing the traps at the edge of the pond and Virkon disinfectant tablets for sterilising the bottles between ponds.
We now sell an even wider range of torches suitable for newt survey.
Traditionalists can buy the classic high powered Cluson CB2 lamps with either a lead acid battery or a lighter longer lasting lithium ion battery. We also sell the new CB3 lamphead allowing you to increase the light output and battery life of your old CB2, and a new range of powerful hand torches from LED Lenser that are more than adequate for newt surveys and considerably less bulky than the Cluson lamps.
Waders and Gloves
Generally the aim is to stay out of the water but occasionally it may be necessary to enter a pond to retrieve lost traps or to access difficult sites. NHBS sells a wide range of waders including both thigh waders and chest waders.
We also sell some excellent new neoprene gloves with a nylon jersey knit palm material allowing the gloves to be worn without compromising dexterity and a thick neoprene back to provide extra warmth.
Walkie Talkies and Whistles
Newt surveys are not without risk and the best way to mitigate these risks is to have appropriate safety equipment. NHBS sells Two-Way UHF Radios so that you can keep in contact with colleagues, and emergency whistles to attract their attention if you do slip into the water. We also have waterproof first aid kits that will stay dry no matter how wet you get.
