The NHBS monthly catalogue lists all book titles that have been added to our website over the last month, classified by subject. The catalogue contains forthcoming titles, as well as re-issues, new editions, and all books new to NHBS. This makes it an invaluable and unrivalled source of information for subject librarians and all who wish to be the first to know about new titles in the subject ranges we cover: natural history, zoology, botany, ecology, sustainable development and conservation.
The catalogue has recently received a facelift to make it easier to use – all of the valuable content remains in place. It is the latest in a long tradition of book catalogues produced by NHBS since 1985, from the old newspaper-style printed catalogues to the bi-monthly NHBS Bulletins, A4 booklets with cream covers which preceded the NHBS monthly catalogue.
Suggesting new titles for the NHBS Monthly Catalogue
NHBS cataloguer Leon Vlieger adds around 300 new books each month: he sifts through countless publisher catalogues, email newsletters, websites, book reviews and customer requests to select the titles. However, we sometimes miss important new publications, and welcome any help our readers can give us. If you know of a title that should be added to the next NHBS monthly catalogue, please email Leon (email@example.com) with the details (title, author, publisher, ISBN).
eDNA or environmental DNA is genetic material found in the environment. This DNA comes from organisms in various forms including (but not limited to) faeces, mucus, gametes, shed skin or hair. Although eDNA degrades over time, it can persist long enough for its presence to be tested from environmental samples.
eDNA sampling for Great Crested Newts
Sampling and testing of eDNA in pond water is a relatively new, but increasingly popular, method of determining presence of Great Crested Newts. Provided that the sampling and analysis protocol complies with DEFRA guidance and that samples are collected between 15th April and 30th June, then eDNA test results are accepted by Natural England and Natural Resources Wales.
Unlike traditional methods of bottle trapping or torch searches, collecting pond water samples for eDNA analysis has very low impact on newts and other pond inhabitants. It also has obvious benefits in terms of labour time, and ecologists are less restricted to specific times of day for surveying. It could also provide a more accurate method of determining the presence of Great Crested Newts which are notably difficult to survey reliably. The technique is not without limitations, however, and can be problematic in ponds with large amounts of algae or sediment or where accessibility is a problem.
How do you collect and analyse eDNA samples?
The sampling process involves the use of a sterile ladle to collect 20 samples of pond water which are then mixed together in a bag. A small volume of this pond water is then added to each of six tubes containing a preservative solution and control DNA. These tubes are returned to the lab where quantitative PCR (qPCR) is used to amplify and measure the GCN DNA (if present), thus determining the presence of GCN eDNA in the samples.
NHBS and Nature Metrics
This spring, NHBS will be working with Nature Metrics to provide a complete GCN eDNA analysis service. Combining our expertise in sourcing, packing and shipping equipment with the excellent laboratory proficiency of Nature Metrics, this partnership will allow both teams to focus fully on our strengths in order to provide a fast and efficient service.
For more information about Nature Metrics and the eDNA, Metabarcoding and Metagenomics services they can provide, please visit www.naturemetrics.co.uk
Deciding which nest box camera to choose can be confusing and several questions should be considered before you make your choice: Do you need a wired version or would a wireless option be best for you? Do you want a camera that you can fit into an existing box, or would you prefer to buy everything already assembled? Will you be able to view your footage on your PC or laptop? Do you want to stream your footage to a website? In this article we will address all of these FAQs and offer some simple advice to make sure that you get the best out of your camera.
Do you want a wired or wireless system?
Wired systems have a cable running from the nest box back to your house or classroom. This cable carries both the power to the camera and the signal from the camera to your TV. A wired setup offers excellent image quality but may not be ideal if you have children or pets in your garden or if a cable running to your bird box will interfere with the gardening. You will also need to feed the cable into your house, either by drilling a hole in the wall or by feeding it through an open window.
Wireless systems do not require a cable between the bird box and the television but instead transmit images to a small receiver situated inside the house. For some cameras, such as the Wireless Nest Box Camera Kit, a power supply will still be required for the camera (i.e. from a shed or outbuilding). Other cameras, such as the battery powered Wireless Nest Box Camera Kit have solved this problem by adding a battery box, allowing the camera to run off D-cell batteries. An advanced version of this camera system is also available. This includes a solar panel which will power your camera while the sun is shining, only switching to battery power at night or on dull days.
Another thing to consider with a wireless system is that the signal can be compromised by other wireless devices in the area or by trees and other structures between the nest box and the house. In some situations this can severely affect your image quality.
Do you want a complete kit or just the camera?
If you are new to this particular aspect of watching and listening to birds, a complete kit, such as the Nest Box Camera Starter Kit or the Wired Camera Bird Box, provide an excellent and economical choice. These kits include a bird box which has a camera ready mounted in the roof. An attached cable plugs into your television and supplies the camera with power. Alternatively, if you want a wireless option, the Wireless Camera Nest Box is a great choice and doesn’t require any complicated assembly processes.
If you decide to go for one of these options then you will need to attach the camera to the ceiling or inside wall of your box yourself using small screws. A small file can be used to file down a part of the side wall to make a space for the cable to pass through. Alternatively you might consider buying a Camera Ready Nest Box which has a clip inside for attaching a camera, as well as a perspex window in the side which helps to improve the quality of daytime images.
What about watching on your computer?
All of the cameras and kits that we sell come with either a cable or wireless receiver that will connect directly to your television. If you want to view or save your footage onto your computer then an additional USB capture device is required. These allow you to connect your camera/receiver to the USB port of your computer and come with viewing software which allows you to watch and record your footage. Available for both Windows and Mac operating systems.
Can I stream my footage to a website?
There are lots of online services which allow you to stream a live feed from your camera online. Many are free if you are happy having adverts on your stream, or you can purchase a monthly or yearly ad-free plan. Our current favourite is Ustream (www.ustream.tv). Take a look at their website for lots of great resources to help get you started.
The Sensory Ecology of Birds is a fascinating new work that explores the sensory world of birds from an evolutionary and ecological perspective. The author Professor Graham Martin gives us some insights into his inspiration, the incredible diversity of avian sensory adaptations, and how studying sensory ecology can help in developing practical conservation solutions.
How did you first become interested in bird senses?
Through owls. As a child I used to listen to tawny owls calling all through the night in a nearby wood and I wanted to know what they were doing and how they did it. My father took me round the woods at night and that experience led me to wanting to know more about the eyesight of owls.
What inspired you to write the book and what kind of readers do you think would find it useful?
I have been studying bird senses all of my working career. Nearly 50 years ago I started to get paid for looking into bird senses; it has been a strange and exciting way to spend my time. After such a long time of investigating the senses of so many different birds I wanted to bring it all together, to provide an overview that will help people understand birds from a new perspective. I think anyone interested in birds will enjoy the book and find it useful. No matter which group of species intrigues you most, this book will enable you to see them from a new perspective. Understanding bird senses really does challenge what we think birds are and how they go about their lives.
Sensory ecology is a relatively new field of research; could you explain a little about what it is and what makes it particularly relevant today?
Sensory Ecology is basically the study of the information that birds have at their disposal to guide their behaviour, to guide the key tasks that they perform every day to survive in different types of habitats. Different habitats present different challenges and to carry out tasks animals need different sorts of information. Birds have at their disposal a wide range of different sensory information, they are not just reliant upon vision. However, each species tends to be specialised for the gaining of certain types of information. Just as each species differs in its general ecology, each species also has a unique suite of information available to them. Sensory ecology is also a comparative science. It compares the information that different species use and tries to determine general principles that apply to the conduct of particular behaviours in different places. For example how different birds cope with activity at night or underwater.
Sensory Ecology also looks at why evolution has favoured particular solutions to particular problems. I think the major result of this kind of approach is that it certainly challenges our assumptions about what birds are and also what humans are. We do not readily realise that our view of the world is very much shaped by the information that our senses provide. We are rather peculiar and specialised in the information that we use to guide our everyday behaviours. My hope is that people will come to understand the world through birds’ senses, to get a real “bird’s eye view”. In doing so we can understand why birds fall victim to collisions with obvious structures such as powerlines, wind turbines, motor vehicles, glass panes, fences, etc. We can then work out what to do to mitigate these problems that humans have thrown in birds’ way.
An understanding of how a species perceives its environment can be very useful in designing practical conservation measures. Could you give us some examples?
Yes, I have been involved in trying to understand why flying birds apparently fail to detect wind turbines and power lines, or diving birds fail to detect gill nets. These investigations have led to a number of ideas about what is actually happening when birds interact with these structures and what we can do to increase the chances that birds will detect and avoid them.
How do you think that studying avian sensory ecology can enhance our understanding of our own sensory capabilities and interaction with the world?
It gives a fresh perspective on how specialised and limited our own view of the world is. We make so many assumptions that the world is really as we experience it, but we experience the world in a very specialised way. Sensory ecology provides lots of new information and facts about how other animals interact with the world, what governs their behaviour, but equally importantly sensory ecology questions very soundly our understanding of “reality”, what is the world really like as opposed to what we, as just one species, think it is like. This is quite challenging but also exhilarating. We really are prisoners of our own senses, and so are all other animals. Sensory ecology gives us the opportunity to understand the world as perceived by other animals, not just how we think the world is. That is really important since it injects a little humility into how we think about the way we exploit the world.
Could you give us some insight into how birds can use different senses in combination to refine their interpretation of the world around them?
Owls provide a good example. Their vision is highly sensitive but not sufficiently sensitive to cope with all light levels that occur in woodland at night, so owls also rely heavily upon information from hearing to detect and locate moving prey. The nocturnal behaviour of owls requires these two key sources of information but even these are not enough. To make sense of the information that they have available to them the woodland owls need to be highly familiar with the place in which they live, hence their high degree of allegiance to particular sites. Other birds, such as ducks, parrots and ibises rely heavily upon the sense of touch to find food items. The degree to which this information is used has a knock on effect on how much the birds can see about them. So a duck that can feed exclusively using touch, such as a mallard, can see all around them, while a duck that needs to use vision in its foraging cannot see all around. This in turn has implications for the amount of time birds can spend foraging as opposed to looking around them, vigilant for predators. In many birds the sense of smell is now seen as a key source of information which governs not just foraging, but also social interactions.
Are there interesting examples of species that are specialists in one particular sense?
Usually birds rely upon at least two main senses that have become highly specialised and which are used in a complementary manner. For example, in ibises it might be touch and vision, in kiwi it is smell and touch, in some of the waders it is touch and taste, but in other waders touch and hearing.
Probably the most obvious single sense specialisations are found among aerial predators such as eagles and falcons, they seem to be highly dependent upon vision to detect prey at a distance and then lock on to it during pursuit. However, we really don’t know anything about other aspects of their senses and there is a lot left to learn about them.
Can you tell us about any species that you have studied that you find particularly fascinating?
Oilbirds; they are really challenging to our assumptions about what birds are, how they live and what information they have available to them.
Oilbirds are the most nocturnal of all birds, roosting and breeding deep in caves where no light penetrates, emerging only after dusk and then flying over the tropical rain forest canopy to find fruit. But they are a form of nightjar! In the complete darkness of caves they use echolocation to orient themselves and calls to locate mates. When searching for food in the canopy they use their sense of smell to detect ripe fruits, they have long touch sensitive bristles around the mouth. And their eyes have sensitivity close to the theoretical limits possible in vertebrate eyes. They seem to rely upon partial information from each of these senses, and use them in combination or in complementary ways. They really are marvellous, but in truth the senses of any birds, and how they are used, are fascinating and intriguing, it is a matter of delving deep enough, and asking the right questions.
In what kind of direction do you think future sensory ecology research is headed?
We now have available a lot of techniques to find out about the senses of birds, from behavioural studies, to physiology and anatomy. Armed with these techniques, and also with ways of thinking and measuring the perceptual challenges of different tasks and different environments, there are so many questions to investigate. We have some fascinating findings but we have only just scratched the surface with regard to species and it does seems clear that senses can be very finely tuned to different tasks. I like to compare the diversity of the bills that we find in birds with the same diversity in the senses in those species.
Every bill tells a story about form and function, about evolution, ecology and behaviour. The senses of birds show the same degree of diversity and tuning. So to me sensory ecology is a wide open field with lot of questions to investigate. To appreciate the world from a bird’s perspective will, of course, give us a much better understanding of how to mitigate the problems that humans have posed to birds by shaping the world for our own convenience.
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
Pond dipping is an excellent activity for children of all ages and is a great way to introduce them to a wide range of plants, insects and amphibians. It also offers an opportunity to learn about food chains and food webs as well as discovering variations in lifecycles and the effects of pollution on aquatic life.
For school groups, a pond dipping trip will satisfy many of the criteria for learning about life processes and living things, and it can also be used to provide inspiration for art, maths or English projects. Younger children will enjoy drawing or painting pictures of the creatures they find, as well as writing stories about their experiences.
Don’t forget though that pond dipping isn’t just for children. Ponds, pools and small lakes are an integral part of our ecosystem and surveying the plant and animal diversity within them is an important way of assessing their health. If you are interested in volunteering as a pond surveyor, take a look at the Freshwater Habitats Trust website for more information.
How to pond dip:
Half fill a tray or bucket with water and set aside. Do the same with your collecting pots and/or magnifying pots (if using).
Use a net to dip into the pond. Sweeping in a figure of eight will ensure that you retain the catch in the net. Areas around the edge of the pond, especially near vegetation, tend to be the most productive. Take care not to scoop up mud from the bottom of the pond, as this will clog up your net and make it difficult to see what you have caught.
Gently turn the net inside out into the tray. Once everything has settled, you should be able to view a fascinating selection of pond-dwelling creatures. A pipette can be used to transfer individual specimens to a magnifying pot for a closer look.
When you have finished, make sure to return all water and inhabitants to the pond. Trays, pots and nets should be rinsed and dried thoroughly before storage. If you are going to be using nets in different ponds then sterilising using a broad spectrum disinfectant will help prevent the spread of disease.
Please note: Children should always be well supervised and aware of health and safety rules when working near water. Suitable clothing should be worn; wellington boots or other sturdy footwear are recommended.
Pond dipping equipment:
At NHBS we stock both individual and class sized pond dipping kits. These contain nets, trays, pots, magnifier and pipettes, as well as the excellent (and waterproof!) Freshwater Name Trail which will help you to identify the key animals found in UK ponds. Or why not choose from our top 10 list of equipment and books for pond dipping:
Made at our workshop in Devon, the Pond Net is a high quality, lightweight net with a removable bag for cleaning. The bag is made from woven 1mm mesh which is ideal for pond dipping. Also available in a telescopic version.
Find out the names of the insects, plants, amphibians and repiles that you see. Features three of the FSC’s popular fold-out charts: Reptiles and Amphibians (frogs, toads, newts, slow worms, lizards and snakes), Freshwater Name Trail (classic pond dipping guide) and Commoner Water Plants (from lilypads to water mint). Also includes a card-sized magnifier.
This set of 10 Bug Pots is perfect for pond dipping, as well as general nature studies. Each pot has a 2.5x magnifying lid and a measurement grid of 5mm squares on the base. They are ideal for storing and observing specimens.
Through beautiful full-page illustrations accompanied by key information about each creature, the First Book of Pond Life will help to encourage young children’s interest in the outside world and the wildlife around them. Covers 35 of the most common pond species. Also includes a spotter’s chart for children to fill in and links to internet-based activities.
A simple and affordable pond net. Knotless mesh is guaranteed not to run if holed and, importantly, will not harm specimens which are collected in the net. A plastic handle makes it very lightweight. Available in three sizes.
Suitable for adults and older children, this books introduces some of the less familiar and microscopic species found in ponds such as diatoms, desmids and rotifers. Along with excellent photographs, the book provides useful identification keys so that readers can identify, explore and study this microscopic world. This book is due for publication March 2017.
Small pipettes are extremely handy for sorting through and picking up tiny creatures found when pond dipping. They can also be used to transfer samples to microscope slides to look at the microscopic specimens found. These 3ml pipettes are available singly or in packs of 10 or 100.
These sampling containers are made from see-through rigid polystyrene and have secure screw-on lids. They are recommended for liquids and so are ideal for keeping specimens when pond dipping or rock pooling. Available either singly or in packs of 10, 30 or 100. Different sizes of pot can also be purchased.
Packed with information on more than 190 species of animal and plant that inhabit ponds, pools and small lakes in northern Europe. Among the fascinating animals featured are freshwater sponges, hydras, water bears, worms, leeches, water snails, dragonflies and damselflies, frogs and toads, bats, fish, birds, water voles and otter.
In this brief guide we will take a look at the main types and designs of moth traps. We will also address many of our most frequently asked questions, including why you will no longer find Mercury Vapour traps for sale at www.nhbs.com
Robinson Moth Traps
Robinson Traps are the preferred choice amongst many serious entomologists because they offer the highest retention rates. On a very good night you may catch in excess of 500 moths. They tend to be more expensive that other types of trap, however, and they are also quite large. They also cannot be collapsed down for storage or transport. The Robinson Trap is available with twin actinic bulbs and is powered by 240V mains electricity.
Skinner Moth Traps
Skinner Moth Traps will attract a similar number of moths to Robinson Traps. However, they are less efficient at holding the catch. The main advantages of Skinner Traps are price and portability, and they also let you access your catch whilst the trap is running. Skinner Traps collapse down quickly and easily when not in use, making them very easy to store and transport. They are available with actinic electrics and can be provided with either 240V (mains powered) or 12V (battery powered) control panels. Lucent traps have a clever design with all components fitting neatly into a suitcase-style case.
Heath Moth Traps
The traditional Heath Moth Trap has a small actinic tube mounted vertically within three vanes that work together to attract and then deflect moths downwards into the holding chamber below. The traps are very lightweight and portable and are usually powered by a 12V battery or generator, although mains powered traps are also available. Variations on the Heath Trap design include the “Plastic Bucket” model which allows the trap to be packed away and carried conveniently. Although catches from Heath Traps tend to be less than for Robinson and Skinner traps, due to their lower wattage bulbs, their affordability and portability makes them great choices for beginners or for use in the field.
Moth Collecting Tents
Moth Collecting Tents provide a unique alternative to traditional style moth traps and are ideal for educational use or group trapping events. They consist of a large white fabric structure which is fitted with a UV light source. Moths which are attracted by the light settle on the white fabric and can be observed or collected for study. As the collecting area is large and accessible, it is easy for many individuals to view the specimens at the same time. However, tents and sheets do not have the same retention rates as traditional box-type traps.
Moth Trapping FAQs
What kind of trap is best for garden or educational use?
The design of the Skinner Trap means that you can access the catch without having to switch off the bulb. This is particularly useful if you are looking at your catch over the course of the evening, rather than leaving the trap all night and returning to it in the morning. Skinner Traps also have the added benefit of collapsing down, making them easier to store.
Which trap is best for unattended trapping?
The Robinson Trap is the only trap that will retain the whole catch after dawn. Some moths will escape from other trap designs.
Which trap is most portable?
Heath Traps are the smallest and easiest to transport. They can also run off a 12V battery, allowing them to be used in remote sites. The Safari and Ranger Moth Traps are the smallest and lightest traps we sell, so are ideal for travelling, however, they do require mains electricity (or a generator) to run.
Why can I no longer find Mercury Vapour traps on your website?
Mercury Vapour bulbs have recently been phased out as part of the Restriction of Hazardous Substances Directive. Therefore, we have removed the traps from our range and are now focussing on actinic replacements. If you have a Mercury Vapour trap and would like to convert it to run with actinic electrics, please get in touch with us to have a chat about this.
What are actinic bulbs?
Actinic bulbs product a small amount of UV light alongside the visible light which makes them more “attractive” to moths. They are not as bright as Mercury Vapour bulbs but because they don’t get as hot they are much safer to use, particularly for public and attended trapping events. They are also much less of a disturbance to neighbours if you are using the trap in your garden.
What is the difference in catch rates between the different traps?
The Robinson Trap and Skinner Trap will attract a similar number of moths but the Robinson has the highest retention rate of the two. Heath Traps will retain fewer moths but will still attract the same range of species. You can therefore obtain similar results trapping for a longer period or over several nights in the same area.
Welcome to our annual tour of recommended reads and equipment highlights brought to you by members of the NHBS team. Here are our staff picks 2016!
The Sauropod Dinosaurs: Life in the Age of Giants
I admit that I’m a bit of a closet palaeontologist. Having decided to forego a career in this field in favour of biology, I have nevertheless retained a fascination for dinosaurs, so I enjoy a good dino-book like no other, and Indiana’s Life of the Past series… oh, wait. Probably the most surprising thing about The Sauropod Dinosaurs is that it was not published by Indiana University Press as part of their Life of the Past series, but instead by Johns Hopkins University Press. For anyone familiar with the aforementioned series, this book would fit right in, and displays similarly high production values, gorgeous illustrations, and accessible popular science. I have yet to go beyond merely flicking through it and admiring it, but I could not resist and got myself a copy as soon as this came out. Leon – Catalogue Editor
The Arctic Guide: Wildlife of the Far North
The Arctic Guide is a fantastic reminder of the precious diversity of wildlife that occupies the Northern regions of the planet – including mammals, birds, fishes, lizards and frogs, flies, bees, butterflies and flora. There is even a fascinating entry on domesticated sled dogs. It is beautifully produced, as we have come to expect from Princeton University Press natural history lists. Well-designed colour plates are accompanied by unusually descriptive detail by author Sharon Chester, making this an enjoyable general read for naturalists as well as an essential companion for Arctic researchers or travellers. Katherine – Marketing
Britain’s Treasure Islands: A Journey to the UK Overseas Territories
To research Britain’s Treasure Islands, and the TV series of the same name that was broadcast in 2016, Stewart McPherson travelled to each of the 16 remote islands and peninsulas across the globe that are under UK sovereignty.
The contrasts between the different territories are fascinating, some can be travelled to with relative ease (e.g. Gibraltar and the Falkland Islands), but others are nearly inaccessible and as a result have most wonderful wildlife – one of my favourite chapters describes the British Indian Ocean Territory, home of undisturbed coral reefs, and giant Coconut crabs.
This hefty book is full of adventure and natural history, with fold-out maps and countless photos, and just perfect for dipping into when it’s cold and windy outside. Anneli – Senior Manager
Bushnell NatureView Binoculars
We all love the Bushnell NatureView Binoculars because they are bright, well balanced and really solid, without being heavy. They have a fantastic field of view for scanning the horizon and an excellent close focus distance so they are brilliant for insect work too. They are very well designed binoculars at a really affordable price. Simone – Wildlife Equipment Specialist
Sapiens: A Brief History of Humankind
Sapiens is a very ambitious book, covering the entirety of human history while exploring what the future holds for our species. You will learn to admire, sympathise with and hate our species as Harari examines the key factors which lead to our success over other animals. Through Hariri’s use of creative metaphors, he successfully manages to answer some of the big questions which would otherwise be incomprehensible. I can’t wait to read his latest book Homo Deus, which further explores the future of our species; where we’re are headed and what challenges we will face. Tim – Customer Services
Bushnell Trophy Cam Essential E2
Whilst carrying out research for my PhD studying chemical communication in the Eurasian beaver I recorded many hours of beaver responses to the scents of intruding neighbours using trail cameras. I also enjoyed taking them home to record animals in my garden and surrounding countryside. The Essential E2 is an affordable yet good quality trail camera that will give you an insight into the animals visiting your garden. It is surprising how many different animals and birds visit gardens without people knowing, although some leave a nice surprise of a dug-up lawn! A friend recently used a trail camera to investigate who was digging up their lawn – badgers looking for tasty leatherjackets! Hannah – Wildlife Equipment Specialist
Cavity nesting bees make up around 30% of the solitary bees in the UK. These non-aggressive insects require dry, hollow tubes to make their nests and use natural materials, rather than wax, to construct the cells in which the larvae grow.
I bought this small wooden solitary beehive for my garden in an attempt to provide nesting space for these vital pollinators. It has been a great addition to the garden and within a month of installing it, several of the holes had been packed with leaves. This was really exciting to see and suggests that it was being used by local leafcutter bees.
The box is well made and has withstood the local Dartmoor weather (i.e. windy and wet much of the time) really well. The wood has weathered attractively over the year and the box still feels robust and sound. As a fruit and vegetable grower it is great to know that we are attracting pollinators to the garden. Luanne – Senior Wildlife Equipment Specialist
Heavy-duty Badger Gate
One of our latest developments is a redesign of an existing product sold by us. Our new heavy-duty badger gates are made on site, welded by our own fully qualified TIG welder, ensuring quality workmanship and a finish we hope the customer is amazed by.
Currently, our competitors only use galvanised mild steel. This results in a cumbersome, awkward to use product. Ours, however, is lightweight but still gives the same strength and reusability, making it far easier to transport to the required area and reduce the strain required to set up a gated badger enclosure. Competitively price, this item should fulfil all your requirements and more, a must have for anyone working towards badger conservation. Thomas – Wildlife Equipment Engineer
Our new pond net frame has been designed and developed to make a more sustainably sourced, budget frame for everyone from young children up. Manufactured in house, it means that we are no longer reliant on external suppliers to fulfil orders, and therefore able to lower the cost to you, the customer. Also, not being shipped from the other side of the world makes it a greener, more sustainable product, reducing airmiles and making it more environmentally friendly. Lightweight, coming in at only 300g, it has two tactile foam handles, fitting very nicely into the hand. Kynan – Fabricator
Arboreal: A Collection of New Woodland Writing
In memory of Oliver Rackham, Little Toller’s Arboreal sets out to curate a journey through the managed and wilder woods of Britain, with some very insightful companions. The book is a perfect blend of collected nostalgia, fancies, facts and little fictions that each in turn highlights something of the wild wood within us. Authors, journalists, artists, poets and woodland custodians impart wisdom, wonder and hope; and each leaves their own mark on the mind with their input. This book is an immersive, beautiful, lyrical and poignant treat, let it take you into the woods, or better still, take it with you and head for the trees! Oli – Graphic Designer
Co-authors James Eaton and Nick Brickle share some of their birding insights and in-depth knowledge of the region’s avifauna in this interview with NHBS.
Could you tell us a little about how you became interested in birding and what drew you to this region in particular?
James – My Grandmother gave me a copy of Benson’s Observer’s Book of Birds when I was six, and, wanting to see some of the birds in the illustrations in real life, my father agreed to take me to the local nature reserve to look for them, and from that point on it became an obsession!
Nick – Similar story. I got hooked before I was 10 years old, partly thanks to Choughs, Peregrines and my dad’s old binoculars on family holidays to Pembrokeshire. Ten years later and I found myself surveying White-winged Ducks in Sumatra and never looked back.
What inspired you to create a field guide that covers the entire Indonesian Archipelago? It must have been quite a challenge to cover such a diverse region.
All four of us are pretty obsessed with the region’s birds, both as a hobby and professionally, and all of us have travelled pretty widely in the region over many years. During this time the region has gone from having no bird field guide at all, to having a variety of books covering different parts of it; some now already long out of print. We all decided it was time to put our passion into a project that could do justice to the spectacular diversity to be found here, and so agreed to work together to create the new guide.
Could you explain a little about the unique biogeography of the region which makes it such a biodiversity hotspot?
Hard to sum it up in a sentence! It’s a fantastic combination of Asian and Australasian bird families, spread across 1000s of islands, with Wallace’s famous line running down the middle, and spectacular endemism throughout. For more, read the biogeographical history section in the introduction to the field guide!
Who is your target audience for the book?
Anyone with an interest in the birds of the region! Visiting and resident birdwatchers are the obvious user, but given that it includes over 13% of the world’s birds, anyone with an interest in birds should enjoy it. In due course we also hope to produce an Indonesian language version of the guide, so as to make it more accessible to the growing number of local birdwatchers.
For someone visiting the area for the first time, what are some of the most exciting sites, and the key species that you recommend looking out for?
Where to start! Within Indonesia, the best places for an introduction are probably the mountains and forests of West Java, which are easy to visit from Jakarta, and where many of the most sought after Javan endemics can be seen; or perhaps North Sulawesi, where a trip to see hornbills, endemic kingfishers and Maleo can be combined with beaches and diving; or Bali, where one of Indonesia’s rarest and most spectacular birds – the Bali Starling – can be seen with a short trip from the beach resorts.
Another choice for an easy introduction is the Malaysian state of Sabah in the north of Borneo. Here many spectacular and endemic birds can be seen from the comfort of first-rate hotels, including Great Argus and the completely unique Bristlehead. After that, the opportunities are limitless!
How do you kit yourself out for a birdwatching trip to the region, and can you recommend a great birding gadget or app?
At the simplest, you don’t need much more than a pair of binoculars (and maybe a rain coat or umbrella!). Beyond that it depends a bit on where you are going and what you’d like to see: a telescope can be useful, but is rarely essential, sound playback or recording equipment can be very useful, a camera if you like to take photos, camping equipment if you plan to visit very remote regions. If you plan to explore off the beaten track (and there are lots of parts of the region that qualify as this!) then a phone and google maps can be a surprisingly useful way to look for patches of forest, and then all you need to do is try and make your way towards them!
Do you have any favourites among the species in the guide? Are there any that proved particularly elusive or challenging to observe?
James – Difficult question, can I give two answers? One would be Helmeted Hornbill. Such an iconic bird that symbolises the region’s rainforests. You know when you hear the bird’s incredible mechanical laughing call you are in the rainforest, but equally you are reminded how it is disappearing from many areas due to illegal hunting for its casque. Another would be Bornean Ground Cuckoo. Once a mysterious bird, largely unknown due to its shy nature, feeding on the rainforest floor, but now as our understanding of the species has grown it is possible to see it. Nothing gets the adrenalin pumping quite as much as looking for this species.
Nick – Too many to choose from! For me it would have to be something that walks on the ground… pretty much any pitta, pheasant or partridge is a candidate. Maybe Banded Pitta (any of the three species…)? Or the spectacular Ivory breasted Pitta? Then of course there is Rail Babbler… Actually, more often than not my favourite is the last new species that I have seen, or the next new one that I want to see!
With so many endemic species, there must be some that fill very specific ecological niches?
Endemism is very high in the region, and many species are only found within very small ranges, such as Boano Monarch on an island only 20km wide, or Sangihe Island, only 40km long at its widest point, and with five endemic bird species. Damar Flycatcher too, found in the dark understorey of a tiny island that requires two days’ boat travel from the nearest city. Kinabalu Grasshopper Warbler is only found on the top of two mountain tops in Borneo. When it comes to specific niches, however, small island endemics are often the opposite, in that they often expand their niche due to the absence of competitors. Birds filling very specific niches are probably more a feature of the large islands groups like Borneo and Sumatra, where the overall diversity is much greater.
It is quite well publicised that one of the biggest threats to the conservation of all Indonesian species is rapid deforestation to create palm oil plantations. Are there other threats to bird species which also need to be highlighted?
Deforestation is a big issue. There has been a huge loss of forest over the last decades, but vast areas still remain, and their value is finally starting to be more widely recognised. Hunting for the captive bird trade also remains a huge threat, particularly to those species most desired as pets, such as songbirds and parrots. Local and international groups are working hard to try and reduce this trade, in particular the public demand, but there is still much work to be done to change attitudes.
How can the international community help to support conservation efforts?
As birdwatchers one of the simplest and best things you can do is to visit the region and go birdwatching! Coming here, spending time, spending money, staying in local hotels, eating local food, using local guides, all serves to create a value to the forests and the wildlife that lives in them. This is not lost on local people or the regional governments. Beyond that think carefully about the products you buy from the region, to make sure they come from sustainable and fair sources. If you have money invested make sure that is not going to support destructive or exploitative practices in the region. Finally, support a good cause! There are many, many local NGOs established and emerging in Indonesia and the wider region, all working and lobbying hard to protect the region’s forest and wildlife. Your support will help them achieve this.
Following the acquisition of EFE & GB Nets earlier this year, NHBS now manufactures a wide range of plankton nets at our workshop in Devon. Nets are available with an opening diameter of 250mm, 300mm or 500mm and with mesh sizes ranging from 10µm to 500µm.
250mm and 300mm diameter nets
250mm and 300mm diameter nets have a stainless steel frame to which a 500mm long bag is attached. They are supplied with a harness and seven metre long towing line which can be used to tow the net behind a boat or from a suitable bank or jetty.
The standard cod end is fitted with a filter in the same mesh size as the main part of the bag. However, various alternatives can be selected at the time of ordering. Options include a clear extension tube, collecting bottle, tap valve or large filter fitted in place of the standard filter. It is also possible to have weight loops added to the end of the net (weights not included) or a stainless steel swivel to be used on the harness in place of the standard nylon ring.
The heavy duty upgrade uses heavy duty nylon for the net collar and cod end collar and also includes fully taped seams.
500mm diameter nets
500mm diameter nets have a stainless steel frame and 1900mm long bag and a three point harness with swivel connector. All seams are reinforced and the collar is made from industrial nylon for added strength and durability. The cod end of the bag is fitted with a heavy duty screw-on filter in the same mesh size as the bag. This net is not supplied with a towing rope and so users will need to supply their own rope or chain which can be fitted to the harness.
As with the smaller plankton nets, various adaptations are available in order to create a net which is suited to your sampling needs. A flexible cod end extension allows a greater sample volume to be collected and also lets you connect a different filter type. A replacement cod end cap provides a closed ended option and results in a sample size of 700ml and a quick release bag is ideal for collecting fry or elver or for when a rapid changeover of bags is required.
Net bags and the educational plankton net
As well as standard plankton nets, we also stock a range of plankton net bags designed to fit onto the professional hand net frame. These fit onto the frame in the same way as the standard hand net bags, and have a detachable screw-on filter in the centre. An educational plankton net with 150µm mesh is also available for school use or for those who require an economical net for trial sampling.
