Supporting Conservation: National Museum of Brazil

On 2nd September last year, a terrible fire destroyed the National Museum of Brazil in Rio de Janeiro. Alongside the vast collection of irreplaceable natural history specimens, the fire also destroyed books and equipment used by the Museum’s researchers for ecological research and wildlife conservation.

Thankfully as museum curator, Débora Pires, wrote shortly after the incident: “The brains did not burn; we are working with a positive agenda!”

A selection of books kindly donated

NHBS were approached by our former director Alan Martin, who provided a list of products which the malacology, arachnology, entomology and lepidoptera departments needed to get back on their feet. Alan, now secretary of the Brazilian Atlantic Rainforest Trust (BART) has close links with many researchers at the museum.

Following this, we decided to coordinate an effort to provide the items that are most critical to their research. We contacted suppliers asking them to contribute and we agreed to supply our own manufactured products, and cover shipping costs of all donated items.

The response from suppliers was fantastic, as the majority were happy to donate all, or most of the items requested. We would like to give huge thanks those who have donated so far: Elsevier, BIOTOPE Parthenope, Brunel Microscopes Ltd, BugDorm, CABI Publishing, Harvard University Press, the Royal Museum for Central Africa, Watkins & Doncaster and finally EntoSphinx. So far, we have received just over £2,000 worth of items, with more to follow.

A selection of items that are being sent in the first shipment.

“I’m really sorry to hear such devastating news. This is truly awful and it’s good to see you are providing such great support to them. We would be happy to send out the [requested] book gratis.” – Linda Jackson, Elsevier

BSBI: Publisher of the Month for April

 

 

 

 

With Spring finally upon us, NHBS are delighted to announce the Botanical Society of Britain & Ireland (BSBI) as our Publisher of the Month for April.

BSBI: Origins and Aims

The BSBI has a long and illustrious history as a publisher of books and periodicals aimed at both professional and amateur botanists. Tracing its origins back to 1836, the society was founded as the Botanical Society of London; from its earliest days, the BSBI has welcomed and supported everyone who wants to know more about the British and Irish flora. The society’s training, outreach and research  programmes continue to support botanists at all skill levels.

BSBI Publications

 

 

 

 

The BSBI publishes a range of botanical books; their BSBI handbooks have become standard botanical field guides, containing identification keys, detailed plant descriptions and useful line drawings, together with information on habitat and distribution. They also publish important stand-alone titles, such as Hybrid Flora of the British Isles and Threatened Plants in Britain and Ireland.

The BSBI have been instrumental in helping to publish John Poland’s critically acclaimed The Vegetative Key to the British Flora and most recently, after years of work, The Field Key to Winter Twigs – both vital reference for field botanists.

Forthcoming Publications: BSBI Atlas 2020

The first atlas of the British and Irish flora was published in 1962. It pioneered the use of ‘dot-maps’ aligned to the OS grid which influence  the hundreds of natural history grid-based atlases that followed.  Work has already started on a third atlas; Atlas 2020  will be published after fieldwork has been completed in 2019. You can find out more, or even get involved by visiting their website.

 

You can browse all the BSBI publications here

The BSBI is passionate about the flora of Britain and Ireland and encourages everybody to become involved.  If you are a novice and want to get started in botany, their get started page is definitely worth a visit.  And if you want to put your botanical knowledge to use, opportunities for volunteers can be found here.

BSBI’s blog often features interviews with authors such as Kevin Walker, author of Threatened Plants in Britain and Ireland and John Poland (The Field Key to Winter Twigs).

British & Irish Botany Journal

British & Irish Botany is a new online journal from the BSBI. The journal aims to provide a new forum for publishing papers and articles relating to the vascular plants and charophytes of Britain and Ireland.

British and Irish Botany will welcome contributions in a number of formats and you can find out more about this forum here.

 

 

 

 

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.

NHBS Guide to newt survey equipment

 

Great Crested Newt. Image  by Lottie

Great Crested Newts are the UK’s most strictly protected amphibian, requiring licensed ecological surveys if a development may affect them. As the first signs of spring emerge, ecologists are preparing for the start of this year’s newt survey season. Below, we have compiled a list of the most common newt survey methods and the equipment needed for each, so that you can ensure you have everything you need as the survey season approaches.

Netting

Netting for adult and larval newts can be a useful tool in both survey and relocation. Here at NHBS, we have designed an amphibian net specifically for the safe and efficient capture of newts. The net bag is attached by a wide velcro collar which prevents newts from becoming caught between the frame and the bag. The bag can also be removed from the frame to be disinfected between sites. The seams have been carefully placed so that they do not come into contact with the front edge of the net, and the material of the bag is a soft 2mm mesh. The net head is 300mm wide and comes with a sturdy, wooden 1.2m handle. We also sell a diamond-shaped amphibian net that comes in either standard depth or deep. Its shape is ideal for easy and safe capture for amphibians and is also available in a collapsible frame for easy transport between sites.

eDNA

The presence of Great Crested Newts can be determined by analysing pond water samples for newt DNA. This process is known as eDNA sampling and is a recent but very effective way of newt surveying that causes very little disturbance to the newts themselves. 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. This year, NHBS has once again teamed up with eDNA laboratory, Nature Metrics to deliver a complete Great Crested Newt eDNA analysis service. Combining our expertise in sourcing, packing and shipping equipment with the excellent laboratory proficiency of Nature Metrics, this partnership facilitates a fast and efficient service. If you would like to find out more about the eDNA services that Nature Metrics provide, please visit www.naturemetrics.co.uk

Dewsbury Trapping

The Dewsbury trap is an innovative design of newt refuge trap that is exclusive to NHBS. The clever design of this trap ensures that any trapped newts have access to both fresh air at the top of the trap and a thermally stable refuge at the bottom of the pond. They can be easily deployed from the edge of the pond meaning that not only is this trap safer for newts, but it is also safer and more convenient for surveyors too. In preliminary trials the Dewsbury trap was found to be more effective at catching newts than traditional bottle trapping methods and can be left unattended for up to 24 hours meaning night visits are not necessarily required.

Please note: we recommend that you contact your national licensing authority (Natural England, Natural Resources Wales, Scottish Natural Heritage, etc) before you purchase this trap. The Dewsbury Newt Trap is not included within either the Level 1 or Level 2 Natural England Class Survey Licence and a separate licence is required

Bottle Trapping

Bottle trapping is a popular method of surveying for both detecting and assessing populations. It can, however, become quite labour intensive, especially if you are looking to cut bottles into traps yourself. To save yourself some valuable time, we sell pre-cut bottle traps with the head inverted and ready to deploy. These can be bought in packs of 40 or 120 and are cut from 2l PET bottles with a 28mm neck diameter. Alternatively, we sell the whole bottles if you would rather cut the traps yourself.

Torching

Torching is a less invasive and effective method of counting/observing newts without the need for capturing them. Torches are recommended to be between 500,000 and one million candlepower and need to ideally last several hours at a time. The Cluson CB2 range is very popular among ecologists and provides 1 million candlepower with long lasting battery life and an easy-to-use pistol type grip. For a more lightweight and economical option, the LED Lenser is a powerful torch that offers up to 450 lumens and a sharply focused circular beam that can last up to 300 hours on a low power setting.

 

Drift Fencing

Fencing can either be used to temporarily exclude or contain newts in mitigation projects. It can also be used to aid the capture of newts for relocation and is typically a short barrier with the base buried underground. Our Tristar Newt Fencing comes in rolls of 100m, is made of UV stabilised polythene sheeting and tinted green. It is designed to resist weather damage and has a life expectancy of 5 years, making it ideal for temporary mitigation projects during development works. It is easy and simple to put up and can be fixed into place with our soft wood stakes.

Pitfall Traps

Often, pitfall traps are used alongside drift fencing in order to trap and translocate newts in relocation projects. They consist of a container that is buried underground often flush with the edge of drift fencing. Both square buckets and round buckets have been shown to be effective and we supply several options depending on your preferences.

Accessories

Below are some accessories that may come in use when surveying Great Crested Newts:

Rocky Shores: an interview with John Archer-Thomson and Julian Cremona

Rocky Shores is the seventh installment of the popular British Wildlife Collection.

Image result for rocky shores bloomsbury

The exciting environment of the rocky shore receives a space in the limelight with this new volume. The authors guide the reader through all aspects of the rocky shore including geology, ecology and natural history. It would make a fantastic addition to any naturalist’s book shelf.

 

 

John Archer-Thomson

John Archer-Thomson and Julian Cremona have spent their lives in environmental education and conservation. They are a former deputy head and head respectively of the Field Studies Council’s Dale Fort Field Centre in Pembrokeshire. John is now a freelance coastal ecologist, photographer, writer and tutor, while Julian is the author of several books on exploration, nature and photography.

Julian Cremona

To introduce the authors and their book, we took the opportunity to talk to them about their inspiration for this volume and ask for tips for how we can get involved with rocky shores. Both authors will be signing copies which are available to pre-order on the NHBS website.

What drew you both to this habitat and inspired the production of this fascinating book?

©John Archer-Thomson

As we say in Chapter 1, we were both born near the coast and grew up loving the sea and so were always drawn to the intertidal, especially as many of the inhabitants are quite weird. From the earliest days with the Dorset Wildlife Trust John enjoyed communicating his love of the shore and the importance of its conservation and the need to respect the natural world. As a child Julian collected all manner of natural material from the shore and after graduation taught seashore ecology in Dorset. We see Rocky Shores as an extension of this mission.

How did you even begin to write this book on such a wide-ranging topic?Forty years of running inter-tidal field courses tends to focus attention on making shores accessible to newcomers, we approached the book from a similar standpoint. John particularly likes molluscs, seaweeds and lichens; Julian, all types of invertebrates especially insects, and as ecologists we love the way the component parts of the system interact, John is also particularly interested in how humans are affecting the shore while Julian has spent much of his life travelling the coast of the British Isles. Thus certain chapters suggested themselves!

What was your most exciting find on a rocky shore that people should look out for in the future?

©Julian Cremona

For John it has to be echinoderms in general and Julian likes the more microscopic life living amongst seaweeds in rock pools. We don’t quite know why, but the little pseudoscorpion called Neobisium maritimum always causes excitement for both of us. They are tiny, only a few millimetres long, quite uncommon and may be found by observing the Black Lichen Lichina pygmaea in which they sometimes hide.

I recommend this book as a fantastic in-depth overview, but what would you suggest readers do to further their rocky shore learning?

John runs a “Rocky shore invertebrates” course for the Field Studies Council at Dale Fort Field Centre. This looks at the ecology of the shore, zonation patterns, adaptations of organisms to this extreme environment and of course the ‘plant’ (and planktonic) life that supports this biodiversity: come on this. Alternatively, there are fold out (FSC) keys for a more do-it-yourself approach, in fact, two of these have been produced by Julian’s daughter Clare Cremona including the Rocky Shore Trail. In 2014 Julian produced a large book called Seashores: an Ecological Guide, which has a huge number of photos to help with the identification of commonly found species and explains how they interact on the shore. A Complete guide to British Coastal Wildlife by Collins and the excellent A student’s guide to the seashore by Fish & Fish. For a more academic, but still very readable, account try The Biology of Rocky Shores by Little et al, Oxford Press.

Although adaptable, rocky shore inhabitants are not invincible, what do you think is the biggest threat to the rocky shore ecosystem and are some species more at risk than others?

©John Archer-Thomson

That’s easy: us. There are too many human beings gobbling up habitat, consuming resources, changing the climate, raising sea levels, acidifying the ocean, over-fishing, polluting with plastic, agricultural and industrial chemicals and so on. Stressed ecosystems tend to be species poor but there are often large numbers of a few fast growing, tolerant species that do well. Northern, cold water species are already suffering range contractions as the climate warms, whereas the opposite is true of southern, high temperature tolerant forms, including invasive species from warmer climes.

Staying on the theme of the future, what is next for you both – another book perhaps?

For John this would be intertidal and sublittoral monitoring and photography. Running courses for the FSC. Talks for local natural history groups. Magazine articles and an update of “Photographing Pembrokeshire” by John & Sally Archer-Thomson, Apple iBooks. Julian has a trio of specialist photography books being published by Crowood press. The first two on extreme close-up photography have already appeared and the third will be published at the beginning of April. He continues to develop new ways to photograph wildlife, especially the “very small”. Coupled with this 2019 includes running further workshops, lecturing and travel – for the wildlife!

NHBS Guide to small mammal survey equipment

Small mammals are common and widespread across many of our terrestrial ecosystems. They play a crucial role in ecosystem food-webs as key prey species for many carnivores and are also useful as indicator species for agricultural change and development. Consequently, surveys of small mammal populations can be a useful tool for ecologists, researchers, and conservationists alike.

Small mammals are most commonly monitored through the use of live traps. These allow a range of species to be monitored simultaneously and also allow biometric data such as weight and sex to be collected. In addition, estimates of population size and structure can be calculated using capture-mark-recapture (CMR) techniques. However, other more passive monitoring techniques such as dormouse nest tubes, hair tube, and footprint tunnels are also available. Below we will take a look at some of the most popular small mammal survey equipment.

Longworth Traps

Longworth traps have been widely used in the UK for many years. They are made from lightweight yet durable aluminium and have been consistently well documented in scientific literature and ecological reports.

The trap consists of two parts: a tunnel which contains the door tripping mechanism, and a nest box, which is attached to the back of the tunnel. The nest box provides a large space for food and bedding material to ensure that the trapped animal is comfortable until release. The sensitivity of the trigger mechanism can be adjusted depending on the target species, although Pygmy shrews have been known to be too light to trigger the mechanism. The door can be locked open for pre-baiting for ease of use.

The Longworth trap comes as two options: with a shrew hole or without a shrew hole (Please note that shrews are a protected species so ensure you are aware of the relevant laws in the country in which you are trapping).

Sherman Traps

Sherman Trap

Sherman traps are another popular live-trap which can be folded flat for ease of transport and storage. They work by a trigger platform which causes the entrance door to shut when an animal runs into the trap. Sherman traps are formed of one compartment and because of this, it can be difficult to add food/bedding into the trap without interfering with the trigger platform. The traps may also distort over time with repeated folding. Sherman traps come in a variety of sizes and lengths so that you can find a trap to best suit your target species and can be purchased as either an aluminium or galvanised version which is more resistant to rusting.

NHBS Water Vole Trap

If you are looking to trap and survey water voles, we offer a water vole trap which comprises an extra large (XLK) Sherman trap with its rear door removed and an attached nesting compartment. This trap is suitable for water vole survey, such as capture, mark, recapture studies, as well as water vole relocation projects.

 

Footprint Tunnel

Footprint tunnels are a less invasive method of surveying small mammals. Species presence/absence can be determined by examining the footprints made by mammals that have walked over an ink pad to reach the bait left in the tunnel. This method is especially useful for determining the presence of hedgehogs that are not otherwise easily ‘trapped’. The tunnel comes with a UK mammal footprint identification sheet; however it may be difficult to distinguish between some species of smaller mammals.

Squirrel Hair Traps

Squirrel hair traps are another non-invasive survey method that is designed for red squirrel survey. When squirrels pass through the baited trap, their hair is collected on sticky tabs within the tube. These hairs can then be analysed to determine whether red squirrels are present in the area.

 

Dormouse Tubes

Dormouse nest tubes are a cheap, easy and very popular method of determining the presence of dormice within a habitat. The tubes consist of a wooden tray and a nesting tube. Dormice make nests in the tubes and it is these that are used as indicators of their presence in the habitat. Dormice are legally protected in the UK and must not be handled unless you have a licence to do so. Nest tubes can be set up and checked without a licence until the first evidence of dormouse activity is found. After that, only a licensed handler can check them.

Introducing new microplastics nets from NHBS

The destruction of aquatic ecosystems is a major issue facing conservationists globally – causes include microplastic pollution, acidification, global warming and over-fishing. The manufacturing team at NHBS have produced a series of new survey nets designed to help researchers gather data on microplastics and to sample plankton more efficiently. This blog describes the sea trials performed using our prototype nets to establish the optimal towing speeds and sea conditions as well as whether the nets worked effectively and were robust enough to withstand exposure to the marine environment.
Three new nets were tested – the Manta Trawl Net, which is designed to sample microplastics in calmer inshore waters and on rivers and lakes. The Avani Trawl Net, which is designed to sample microplastics in rougher, offshore environments and the Bongo Net (a pair of 300mm plankton nets joined in the middle and weighted with a depressor vane) which is designed to allow researchers to use two different mesh nets during a single trawl. Plymouth Sound was an ideal location, as we had both inshore and offshore designs to test and the breakwater provided us with easy access to both sheltered water and the open ocean.

The first design tested was the Bongo Net. The net performed very well. The sampling depth was easily adjusted by modulating the speed of the boat and the depressor vane kept the net level in the water.  In our tests the Bongo Net performed best at towing speeds of between two and four knots.

Next, we tested our inshore Manta Trawl Net. The Manta Trawl Net is designed for microplastics sampling in calm inshore waters and on rivers and lakes. The Manta Trawl Net has a post box shaped aperture and twin ‘wings’ (manta wings) mounted onto the frame which serve to lift the net frame so that samples are efficiently collected at the top of the water column. This net was tested at a variety of towing speeds and performed best at speeds of between two and four knots.

The last net to be tested was The Avani Trawl Net. The Avani Trawl Net is designed for offshore microplastics sampling. The vertical orientation of the aperture of the net ensures that samples are collected from the top few centimetres of the water’s surface in slight to moderate swell conditions. To test this net, we ventured out beyond the breakwater where the swell was approximately 1-2m. The net stood upright and performed as expected at speeds of between four and eight knots when exposed to smaller waves of approximately one metre in height. When approaching larger waves, we found that the net had a slight tendency to cut into the side of the wave at speeds of between six and eight knots and that the net performed best at slightly lower speeds.

Avani Trawl Net

All of the nets functioned properly, and our haul included both microplastics and icthyoplankton (fish eggs and larvae). Both the frames and the nets also withstood the sea conditions well and we could find no faults with their design or build – all told a successful trial.
If you are interested in these nets look out for them in our 2019 catalogue, find them on nhbs.com, or contact us on customer.services@nhbs.com and we will send you more information as soon as it becomes available.

 

The 40th Big Garden Birdwatch – January 2019

This year’s Big Garden Birdwatch will be held from 26-28 January: are you ready?

The RSPB Big Garden Birdwatch is the world’s largest garden wildlife survey – now in its 40th year! What began as a simple activity for junior members of the RSPB has now grown to a UK-wide activity with over half a million people regularly taking part. With 40 years of data to look back on, this annual event has become important in helping the RSPB monitor trends in the distribution and abundance of birds in the UK.

The Big Garden Birdwatch is easy to join (and you don’t have to be a member of the RSPB). Here’s how to take part:

  1. Sign up through the RSPB website.
  2. Choose a good place to watch from for an hour between between Saturday 26th and Monday 28th January – either your garden, or a local park or green.
  3. Relax and watch the birds.
  4. Count the maximum number of each species you see at any one time. For example, if you see a group of three house sparrows together and later another two, and after that another one, the number to submit is three. That way, it’s less likely you’ll double-count the same birds.
    Make a note of any other wildlife that you spot as well.
  5. Submit your results, either on the Big Garden Birdwatch website, or by posting a paper form. Even if you don’t see anything, that’s still useful information.
  6. Look out for the results.

You don’t need much to take part in BGB apart from a nice hot drink, some snacks and a pen and paper; but if you’d like to brush up on your garden wildlife here are a few books and items that can get you started:

RSPB Pocket Guide to British Birds £6.99
