NHBS Guide: Where to Hang and How to Maintain your Bat Box

Natural roosting sites for bats are in decline due to changes in building standards and countryside management practices. Installing a bat box is a simple and affordable way of providing much needed roost space for a variety of species and now is the ideal time to install one, before bats fully emerge from hibernation. However, placing your bat boxes in the correct location and at the correct height is essential to encourage bats to occupy them. With this in mind, we have put together some answers to the most frequently asked questions about bat boxes – covering where and when to put up your boxes, cleaning and maintenance, and the legalities of checking whether they are occupied.

Which bat box should I purchase?

Bat boxes can be placed in trees, on walls and on or in the brickwork of buildings. To help you choose the most suitable bat box based on where you want to locate it, take a look at our three-part series designed to help you make the right choice:

Top 10 Bat Boxes for Trees and Woodland

Top 10 Bat Boxes for Walls and Fences

Top 10 Bat Boxes for New Builds and Developments

When is the best time to put up a bat box?

Bat boxes can be installed at any time of year, but they are more likely to be used during their first summer if they are put up before the bats emerge from hibernation in the spring. If you are installing bat boxes as part of an exclusion project from a building, it is best to erect the boxes four to six weeks before the exclusion.

Where should I hang my bat box?

All bat boxes should be positioned at a height of 3-6 metres (the higher the better) in an open, sunny position (6-8 hours of direct sunlight, or in a location where it receives the morning sun if this is not possible). Try to install the bat box where it will not be disturbed by bright lights at night such as porch or security lights.

The most common location to hang a bat box is on a tree using a strong nail that is at least 85 mm in length. It is important to use aluminium nails, as these will not damage a chainsaw (or chainsaw user) should they be left in the tree when it is felled. For more details on how to hang your bat box to a tree, wall or fence, please read our blog on where to hang and how to maintain your nest box, which, although mainly focused on bird boxes, is equally relevant for bat boxes.

How do I check whether the box is occupied?

Many bat boxes have an opening at the bottom and do not require any maintenance as the droppings will simply fall out of this space. If cleaning is required it is essential that you ensure that the box is not occupied before carrying out any maintenance. Once bats have inhabited a roost site they may only be disturbed by licensed bat workers. If you are unsure whether your bat box is occupied the best way to check for box occupancy is to observe the box at dusk (15 minutes after sunset for around 30 minutes) to watch for any bats leaving. Additionally, you can look under and nearby the box for guano (bat droppings). If there are bats present, wait until later in the season and then check again. It’s also a good opportunity to use a bat detector to identify the bats in your box – take a look at our guide on bat detecting for beginners.

How do I maintain my bat box?

The best time to clean the majority of bat boxes (those suitable for summer roosts) is during the autumn or winter. Once you have ensured the bat box is not occupied you can open the box and clean out any droppings. Whilst you are cleaning the bat box it is a good idea to look for any damage, as this may mean it is unlikely to be used. The most likely damage will be broken seams around the roof, because the constant heating and cooling during the day can warp the wood slightly. To repair this, we would recommend using a roof sealant.

Seven Female Nature and Science Writers to Read for International Women’s Day

To celebrate International Women’s Day we have put together a selection of incredible nature and science writing books from some brilliant female writers.

Tamed: Ten Species that Changed our World

by Alice Roberts

In Tamed, Dr. Alice Roberts uncovers the amazing deep history of ten familiar species with incredible wild pasts: dogs, apples and wheat; cattle; potatoes and chickens; rice, maize, and horses – and, finally, humans. Alice Roberts not only reveals how becoming part of our world changed these animals and plants but shows how they became our allies, essential to the survival and success of our own species – and to our future.

Poached: Inside the Dark World of Wildlife Tracking

by Rachel Love Nuwer

In Poached, science journalist Rachel Nuwer takes us on a harrowing journey to the frontlines of the illegal wildlife trade, exploring the forces currently driving demand for animals and their parts – such as the widespread abuses of Chinese medicine and the links with drug trafficking and international crime cartels – and introduces us to the individuals battling to save them: the scientists and activists who believe it is not too late to stop the impending extinctions.

Spirals in Time: The Secret Life and Curious Afterlife of Seashells

by Helen Scales

Helen Scales tells the story of the seashell, showing how these simple objects have been sculpted by fundamental rules of mathematics and evolution, how they gave us colour, gems, food and money, and how they are prompting new medicines and teaching scientists how our brains work. Seashells offer an accessible way to reconnect people with nature, helping to heal the rift between ourselves and the undersea world.

H is for Hawk

by Helen Macdonald

Destined to be a classic of nature writing, H is for Hawk is a record of a spiritual journey – an unflinchingly honest account of Macdonald’s struggle with grief during the difficult process of the hawk’s taming and her own untaming. At the same time, it’s a kaleidoscopic biography of the brilliant and troubled novelist T. H. White, best known for The Once and Future King. It’s a book about memory, nature and nation, and how it might be possible to try to reconcile death with life and love.

Field Guide to the Ladybirds of Britain and Ireland

by Helen E Roy

Professor Helen Roy’s research focuses on the effects of environmental change on insect populations and communities. This illustrated field guide covers all 47 species of ladybird occurring in Britain and Ireland in a handy and easy-to-use format. Twenty-six species are colourful and conspicuous and easily recognised as ladybirds; the remaining species are more challenging, but the clear illustrations and up-to-date text in Field Guide to the Ladybirds of Britain and Ireland will help to break down the identification barriers.

The Accidental Countryside: interview with author Stephen Moss

Stephen Moss is a naturalist, broadcaster, television producer and author. He is the original producer of the BAFTA award-winning series Springwatch and has worked with David Attenborough, Chris Packham, Alan Titchmarsh, and other leading naturalists. Passionate about communicating the wonders of nature, he also lectures in Nature and Travel Writing at Bath Spa University. Originally from London, he lives with his family on the Somerset Levels and is President of the Somerset Wildlife Trust.

In The Accidental Countryside: Hidden Havens for Britain’s Wildlife, Stephen writes about the secret places, that are often overlooked when it comes to protecting habitats and wildlife. Stephen has given his time to sign copies and answer our questions about these vital habitats in our hidden corners.

What inspired you to write about the ‘hidden havens’ for Britain’s Wildlife?

I’ve always been fascinated by these forgotten and secret places, that are often overlooked when it comes to protecting habitats and wildlife. As I say in the book, I first got my passion for the natural world by visiting the gravel pits near my suburban home; today I live near the Avalon Marshes in Somerset, another post-industrial habitat, created from disused peat diggings. During my career at the BBC Natural History Unit, I often filmed at these edgeland locations, as they harbour such a range of interesting wildlife, and are often more accessible to people than classic nature reserves in the countryside.

Of all the places you visited, which habitat surprised you the most regarding its biodiversity?

That’s a tricky one, as I think they all surprised me in some way or another. The Avalon Marshes is probably the most packed with wildlife – three species of egrets, marsh harriers, bitterns and the famous starling murmurations on winter evenings – but I also loved the Montiaghs (in rural Northern Ireland, where peat was dug by hand), Parc Slip in South Wales (a former open-cast coal mine) and best of all, Canvey Wick in Essex, Britain’s first brownfield nature reserve, and a paradise for invertebrates including rare dragonflies and damselflies.

Your book features exceptional and inspirational people that have found ways to make the most unlikely places wildlife friendly. Is it possible to highlight just one project that has succeeded against the odds?

Again, the Avalon Marshes stands out: once the peat had been removed, we were left with an ugly, scarred and wildlife-free landscape, which it was suggested could be used as a landfill site for Bristol’s domestic waste. Thanks to a local campaign, they were instead turned into nature reserves; thirty years later this is one of the best places for wildlife in the whole of the UK. Others include Canvey Wick, which again could have fallen to the developers; the roadside verges of Blandford Forum in Dorset, which are now awash with wildflowers and butterflies each summer; and the RSPB’s Window on Wildlife at Belfast Docks, home to breeding Arctic Terns.

Is there one habitat that you think hasn’t reached its wildlife friendly potential?

That’s easy! The rest of the ‘official’ countryside – the 70% of the UK that is used for farming. Of course we need to produce food, but not at the expense of wildlife, which is what is happening on the vast majority of farms at the moment. Some visionary farmers are working with conservationists to buck the trend – for instance, the Marlborough Downs Nature Improvement Project in Wiltshire – but most are simply fulfilling the consumer and supermarkets’ demands for cheap food, whatever the cost to the environment.

You have been writing for many years and unfortunately, wildlife has suffered a substantial decline over the last few decades. Has your recent experience writing The Accidental Countryside left you more optimistic or more pessimistic regarding the future of wildlife in the UK?

I’d love to live in a country where the sites I feature in The Accidental Countryside are not important because the wider countryside has been transformed into a haven for wildlife. But I’m not holding my breath, despite the things we hear from the government. Now, more than ever, we need to understand that a healthy, wildlife-filled environment is not some ‘bolt-on extra’ to our lives, but essential – to the health and well-being of nature, of ourselves, and of course for the planet as a whole. So I have to be optimistic: there is no other choice!

Are there any books or projects that you are currently working on that you can tell us about?

Yes, I am just about to deliver the third in my series of ‘Bird Biographies’ for Square Peg (Part of Penguin Random House). Following bestselling books on the Robin and the Wren, I am now writing about that classic sign of spring and summer, the Swallow. I am a late convert to Swallows – only since I moved from London to rural Somerset in middle age have I grown to appreciate this classic bird of the British countryside. Writing this book, I have also grown to appreciate that the swallow is, as the writer Collingwood Ingram once noted, “beyond doubt the best known, and certainly the best loved, species in the world.”

Author Interview: Mike Potts, Untangling the Knot, Belugas & Bears: My Natural World on Film

Mike Potts’ career as a wildlife cameraman took him to many of the world’s most spectacular locations and involved filming with Sir David Attenborough.

Mike has signed copies and answered questions about his new book, Untangling the Knot, Belugas & Bears: My Natural World on Film, giving readers the chance to travel with him and share his incredible experiences.

Mike on location with Sir David Attenborough.

What made you pursue a career as a wildlife cameraman? From an early age I developed an interest in natural history and photography, particularly of birds. I was fortunate in being able to turn a passionate hobby into a profession from early beginnings with the RSPB Film Unit.

How did you manage a work-life balance when your work took you far away for significantly long periods?

My wife, although working herself, was able to run things at home in my absence.

Today, there is GPS and the internet: 30 years ago that technology wasn’t as advanced. What difficulties did that present and how were they overcome? (I’m trying not to say, did you ever get ‘lost’?)

In the early years of my career, before mobile phones, we would often be out of contact for many days, or weeks, when out in the field camping. On some trips, we did have the use of the early satellite phones, so at least there was some contact. Having a local biologist that was familiar with the terrain was essential, otherwise getting lost was a real possibility. It did happen in Australia when I was lost on my own in a tropical forest for several hours, quite scary!

Was there one exceptional location you filmed in that stood out from all the rest?

Alaska particularly has many special memories. I spent over a year there working on three 50 minute programmes. If I had to choose one location, it would be the McNeil River in SE Alaska; here brown bears gather in summer to feed on salmon moving upriver to spawn. Sometimes, over 50 bears can be seen in the river, and standing shoulder to shoulder use various different techniques to capture the fish that are so essential to put on fat for their winter hibernation.

What does ‘Untangling the Knot’ in the title of your book refer to?

Some years ago I worked on a film called ‘Untangling the Knot’, which was about the bird, the Red Knot. It has a long migration from its wintering grounds in South America to breeding grounds in the high Arctic of Canada. So ‘Untangling the Knot’ was the story of the feeding habits, complex migration routes, and remote breeding areas of these great travellers.

If someone was inspired to pursue a career filming wildlife, what advice would you give them to get started?

When I started my filming career in 1978 everything was shot on film, which was expensive, as was the equipment to shoot it with. The only way to prove your ability was to shoot a sequence and try to get it seen by wildlife producers at the BBC Natural History Unit or the RSPB film Unit. There were not any wildlife film courses back then. Now there are many more people interested in becoming wildlife cameramen, so the competition is great. What advice would I give? One advantage now with the proliferation of video cameras at low cost is that it is possible to go out and shoot a sequence at no great expense. Choose a subject that you have good knowledge of and try to shoot it differently from what has been done before, then get it seen by someone within the business. If you have access to a scarce or unusual subject, even better, especially if it is on your doorstep (always check licence requirements). You can of course try and get a placement on a ‘wildlife film making’ course but that doesn’t mean a job at the end of it. Virtually all cameramen are freelance, so work is never guaranteed. Good luck.

Can you recall any one moment or experience in your career that encapsulates all that being a wildlife cameraman involved?

I think the most rewarding experience was filming Birds of Paradise in New Guinea. Sitting in my tiny mosquito-filled hide in the pitch-black, 150 feet off the ground, I wondered quite what I was doing there. Then as the dawn began to break and the chorus of tropical birds started I knew why. Shortly afterwards as the first Greater Birds of Paradise appeared the excitement was overpowering. Several males with their golden plumes were bouncing around just 60 feet in front of me, courting the growing number of females nearby. This made all the 3.00 am starts, the long walks through the forest and the exhausting tree climbing worthwhile.

What are your current plans and are there any future projects you can tell us about?

I am now retired from filming, and although I have been trying to get a film off the ground on the Albatross, it is difficult to get the substantial funding for these projects. For the last 2 years I have been writing the book and having exhibitions of my photographic work.

Untangling the Knot, Belugas & Bears: My Natural World on Film
Paperback, published February 2020 £16.95 ~~£20.95~~

Mike has spent more than 30 years as a wildlife cameraman. A highlight of that career was filming the Birds of Paradise and Bowerbirds with David Attenborough.

Bone Building Books: an interview with author Lee Post

We recently became aware of a fantastic series of manuals that give readers instructions on how to clean, prepare, and articulate animal skeletons. We caught up with the author, Lee Post, a self-professed bone man, to ask him more about these guides and his work.

Hello Lee, thanks for the opportunity to ask you some questions. How does one become a bone builder? Was this always something you were interested in or did you fall into this more or less by accident?

As a child, growing up, I was a classic nature nerd. My room looked more like a Victorian curio cabinet than some place someone might actually sleep. Anything related to the animal kingdom was something I was interested in collecting. The ultimate treasures were bones and skulls. But I had never thought about articulating anything myself. My passion for articulating skeletons grew out of a move to a small town in Alaska that had a very progressive little natural history museum. I had a part-time job in the winter and volunteered the rest of my time at this museum. I was given an opportunity to research and articulate a 17 foot Stejnegers Beaked Whale the staff had collected and cleaned. That was my first winter project. My research into how to articulate that skeleton came to a lot of dead ends and some questionable advice. I could find nothing in print on building whale skeletons. With a background in bicycle mechanics and carpentry, and a lot of suggestions from local craftsmen and women, I got that skeleton together, and from then on I never stopped working with bones. Collecting, cleaning, building, illustrating, curating. It was being in the right place at the right time under the right circumstances. In other words, a total accident.

What made you decide to write manuals on constructing and articulating skeletons?

For years I’d been cleaning and articulating a skeleton or two each year. This led to a 3-year Pratt Museum, Homer High School collaborative project, in which I worked at the school with all kinds of interested students. We articulated a 41 foot long sperm whale in the school, and the

following year students worked on about a dozen other skeleton projects, ranging from sea otters to a moose, to porpoises, to a porcupine. The exhibited work they did in their school was open to the public over the following couple of summers. Teachers and educators from lots of places that saw those exhibits wanted to know how they could do similar projects with their students. I had kept a notebook on almost every skeleton I worked on and from those made some crude, hand-lettered, illustrated manuals on how to prepare and build animal skeletons. My day job was working in a bookstore, and there were no books in print on working with bones. This was 20 years ago. Later, an intersection of those hand-printed, photocopied notes, and me, and a talented lady (now my wife) who knew how to do desktop publishing, resulted in the birth of the Bone Building Books about 15 years ago.

Who buys these guides? Do you find that they are used by museum curators, or mostly by individual naturalists? And what has the feedback been?

The manuals were originally written for teachers and students who wanted to do a museum quality skeleton on a limited budget, with materials they

should be able to find even in a small town. Over the years, the manuals have been enlarged and corrected and improved each time I have worked on that type of skeleton. I’m always trying different materials and testing new techniques. Today they are used by everyone from teachers to museum workers, to home hobbyists to University projects with students. The other group of people who were getting these were bone collectors and zoo archaeologists who really just wanted to look at the pictures. They had no interest in the articles or in building a skeleton. And the manuals didn’t even have a centerfold. The feedback has been very enthusiastic. For many hobbyists and home naturalists who have wanted to get accurate information on how to prepare the bones and build the skeletons, these have been their bibles. When people get stuck, they often e-mail me. That’s often a clue I didn’t explain something well enough, and the next revision will try to remedy that.

What advice do you have for aspiring bone builders?

Don’t plan on doing this for a career. You would likely starve. But if this is your interest and passion, there is enough information out there these days that you should definitely pursue that interest. There are no skeleton police. There are no university degrees in this. Many of the best skeleton articulations of land mammals are being done by home hobbyists. You too could be doing that.

From the short video clip of Indie Alaska that I saw, it seems you teach courses to students. Do you also offer workshops for museum professionals?

A wolf that a 6th grade class in Alaska cleaned and articulated as part of a week-long class project. © Lee Post

Many of my favorite projects have been done with groups of interns and docents in museums and marine-life centers. On occasion, the paid staff have joined in, but usually, the staff has too much other work to be able to take the time off to do much hands-on work building a large skeleton. My favorite projects are when I have an enthusiastic group of volunteers and an organization with someone who wants to organize a large skeleton build project. Then, I get to teach and be the foreman and boss around the volunteers, who get the thrill of working with real bones and being part of a team that builds a world-class skeleton.

Are there any particularly challenging skeletons you worked on, or any particular animal skeletons you would still love to tackle?

I’m still sorting out sea turtle skeletons. They have very unusual bones. I’ll be trying to figure out a crocodile skeleton soon. I’m always interested in working on new marine mammal species. They are the animals I have the most experience with.

You have now written nine guides to specific animals and animal groups, plus a general reference book, the Bone Builder’s Notebook. Are there plans to write any more guides?

I’m doing a lot of illustration work on bird bones. I can imagine these might

one day get compiled into some type of identification guide to bird bones. I’m also getting more and more requests for information on articulating reptiles. I live in Alaska, and there is a serious lack of reptiles in my area. However, I’ll be working on some large reptiles in Mexico in the near future, and I never know when I’ll get so inspired that I might try to write something useful on how those bones fit together.

Herpetofauna Workers’ Meeting 2020

Wind farms, conflicts in conservation, and the use of photo identification as a population monitoring technique were amongst the many themes covered at the 2020 Herpetofauna Workers’ Meeting. Running for over 30 years, this popular event attracts ecological consultants, academics, students, and conservation organisations from far and wide. As the weather worsened with the arrival of Storm Dennis, we settled in for a jam-packed two days filled with presentations, workshops, and poster displays.

So how is a talk on wind farms relevant at a herpetology conference? Wind farms cover a large expanse of land and, as Jeanette Hall from the Highland Biological Recording Group explained, could provide a conservation opportunity for Adders Vipera berus. Birds of prey are typically the main predator of Adders, but these predators are present in low numbers on wind farms. If managed correctly, wind farms could offer a suitable refuge for Adders. To test this Jeanette and her team used clay snake models to measure avian attack rates both within the wind farm and on a control site roughly a kilometre away. The models were made to roughly the same size as a yearling Adder, and the attacks were recorded by the presence of talon marks on the clay models.

Despite observing raptors in both sites, they found that attack rates were significantly lower on the wind farm. Interestingly, attack rates were higher in areas where grazing sheep were present.

With grazing and habitat management in mind, could these vast areas that wind farms cover offer an opportunity for reptile conservation?

Clay snake models are one simple but effective approach for measuring attack rates. Suzanne Collinson, from the University of Cumbria and the Cumbria Amphibian & Reptile Group, discussed another interesting technique that she used when studying Slow Worms Anguis fragilis. She used photo identification to study the size and dynamics of a Slow Worm population in a churchyard in Dalston, Cumbria. Slow Worms are a UK Biodiversity Action Plan priority species and protected under the Wildlife and Countryside Act 1981 due to their overall decline, therefore this population in the village of Dalston is of great interest, especially to the locals. Due to their morphology and cryptic behaviour, mark and recapture is a difficult method to use to survey Slow Worms. In addition to this, the markings on the neck and chin of a Slow Worm are unique to the individual and so, photo identification could offer a viable monitoring method.

Slow Worm, image by Bernard Dupont via Flickr,(CC BY 2.0)

In order to take a photograph of an individual, the Slow Worm would be placed on a clear tray, enabling photographs of the Slow Worm’s ventral surface to be taken quickly. The Slow Worms were found at various shelters or ACO’s (artificial cover objects) that were positioned across the churchyard. Suzanne also measured the body length of each new individual that she photographed and recorded the ambient temperature and the number of ant nests and snails present at the ACO. Suzanne counted 25 individuals in total (the original population estimate was 18) and found that as temperatures increased, Slow Worm encounters decreased. Ending on this note, Suzanne discussed the potential implications of climate change and how future monitoring will be necessary to understand what these future impacts could be on the population.

On both days there was a choice of five different workshops, all on very different topics, that we could take part in. On the first day, we attended ‘Managing habitats for conflicting species’ led by Jim Foster and Andrew Hampson from the Amphibian and Reptile Conservation Trust. Faced with a real-time scenario, we discussed in small groups the potential conflicts that could arise and what approach should be used to move forward – our scenario was based at the dunes of Sefton coast, and focused on the population of Natterjack toads that reside there. This was an interesting opportunity to hear what lessons had been learnt from previous conservation projects and how this knowledge can be used for effective conservation planning in the future.

Of course, this is just a snapshot of the range of topics discussed over the duration of the conference. Hearing first hand what organisations such as the Amphibian and Reptile Conservation Trust and Amphibian and Reptile Groups of UK are doing to conserve reptile and amphibian species in the UK, plus the ongoing research on both British species and those of other countries was fascinating.

NHBS: In The Field – Pulsar Helion XP50 Thermal Imaging Scope

Pulsar Helion XP50 Thermal Imaging Scope

Thermal imaging technology has become an invaluable tool for researchers and ecologists studying nocturnal, crepuscular, cryptic or reclusive species. Thermal imaging devices work by using an electronic detector to convert heat emitted by the subject into a visible colour pattern. They have a distinct advantage over other night vision technologies in that you can use them during the day and in foggy conditions, as well as in total darkness. This means that they are ideal for surveying bat roosts, detecting nocturnal foraging animals, spotting birds in cover and even nest finding.

Daytime image of a Blue tit (5x magnification)

We tested the Pulsar Helion XP50 Thermal Imaging Scope at night time and in daylight. Our aim was to see if it enhanced our ability to detect and observe animals. We also wanted to examine the quality of the footage it produced.

The Pulsar Helion XP50 is a powerful thermal imaging scope with 640 x 480 resolution and a detection range of up to 1800m. With a 50Hz frame rate it is great for observing even fast moving animals such as bats. The XP50 has inbuilt memory for storing video and still images, which can then be downloaded later via USB. Alternatively you can live stream, record and store images and video on a smartphone or tablet via the Stream Vision app.

How We Tested

We took the Pulsar Helion XP50 out a few times during daylight and night time to test its capabilities in as many conditions as possible. Steve went out searching for Lesser spotted woodpeckers on Dartmoor, Simone took the scope out to get some night footage of woodcock and we tested the daytime recording functionality again near the NHBS head office.

To get night time footage we tested the XP50 on a very drizzly, foggy evening in January, on agricultural land in Dorset that is managed organically. We knew this was a good area for overwintering woodcock and hoped to spot some foraging along with other wildlife. The scope is an all-in-one unit, so we just took it in its case and didn’t need any other accessories.

What We Found

We found the scope easy to use one-handed, particularly due to the strap and the design of the button interface. It was simple to switch magnification zoom setting, take still images or videos, change colour palette and look at the stadiametric rangefinder one handed, meaning we could maintain our focus on the wildlife in front of us. All of the menu options appear on the screen and on recordings so you know what settings you had when you took the footage. The detection range was impressive and we easily spotted larger animals such as deer and hares when scanning the fields in the dark.

The WiFi streaming was exceptionally easy to set up and a fantastically useful tool to allow other people to view what was happening through the camera. It also allows you to control the camera and record footage. Downloading images from the internal camera memory via USB was very simple afterwards.

Daytime use

We obtained good daytime footage of squirrels and passerines such as blue tits, robins and blackbirds, with the scope making it very easy to pick out birds moving through the leafless tree canopy. The mallards on the river near NHBS head office were easy to spot without the scope but it did help us find a hidden teal and a moorhen that we would have missed otherwise.

Night time use

The XP50 came into its own at night and we picked up many animals that were missed when we surveyed the area with a lamp, even small animals such as mice and meadow pipits. We detected animals through the fog, drizzle and some ground cover with ease. We spotted roe deer, hares, rabbits, mice, meadow pipits, woodcock and a barn owl. The bird species were easy to follow when flying and provided smooth video footage due to the fast frame rate.

Our Opinion

We think that the Pulsar Helion XP50 is an absolutely fantastic thermal imaging scope and would be a great addition to any researcher or ecologist’s survey equipment collection. The standout features are the detection range, the one handed operation and the streaming function. We would advise users to memorise the shortcut buttons before you go out as it can be difficult to remember how to switch modes in the field. The magnification zoom was useful if animals were fairly close but the footage became very blurry if they were further away so we tended to stick to 2.5x or 5x. Camera shake also becomes a real problem at the higher magnifications and a tripod would have improved our recorded footage quite dramatically. Thermal imaging technology opens up a world of possibilities for night time wildlife watching, bird ringing and surveying and we think this is an excellent scope for all of these purposes.

Installing nest box cameras at NHBS

Now is the time of year when many bird species are starting to defend territories more noisily and to look for suitable nest sites. To coincide with National Nest Box Week (14th to 21st February), we have been busy selecting our favourite nest boxes, updating our advisory blog posts on where to site nest boxes and how to put them up, and installing our own nest box cameras at our warehouse in Devon.

At this time of year, the birds will currently be exploring nest sites and should start bringing nesting material into the boxes in the next couple of weeks.

Given that it has been a mild winter, the breeding season should start earlier this year, but we still would not expect the first eggs to appear until April. This means that there is still time to get a nest box up in your garden to provide much needed nesting space for birds. You could even consider enjoying this amazing spring spectacle up close with a nest box camera.

Choosing the nest boxes and cameras

We chose two of our Camera Ready Nest Boxes because they have a perspex panel in the side to let in extra light, which gives better daytime images in colour, and a camera clip on the lid. We then selected two of our most popular cameras, the WiFi Nest Box Camera, which can stream footage directly to a smartphone or tablet, and the IP Nest Box Camera, which can provide a live stream to a website. There are many options available when it comes to selecting a nest box camera, and our blog post on Watching Wildlife – How to choose the right Nest Box Camera can help you decide between the different options.

The Camera Ready Nest Box and IP Nest Box Camera

How to install the camera in the nest box

The procedure for attaching the camera to the lid was the same for the WiFi and IP cameras. We found that the easiest way of installing the camera into the box lid was to attach the camera bracket to the lid first and then to attach the camera to its bracket afterwards. We unscrewed the camera clip with a large Phillips screwdriver, slid the camera bracket underneath the clip on the inside of the lid and then tightened the clip screw back up again.

Unscrewing the camera clip and attaching the bracket

Then we attached the camera onto its bracket using a very small Phillips screwdriver.

Attaching the WiFi camera to its bracket

With the WiFi camera we found that it was best to point the aerial downwards because our nest box roof was sloping. You can check the angle of the camera through the perspex panel on the side – it is best to have it pointing directly downwards and not angled. Ensure that the camera cable is running out of the notch on the back of the box so that the lid fits down snugly.

Putting up the nest boxes

We sited the nest boxes on the eastern side of the building close to the tree cover along the river. To maximise the chances of occupation, it is advisable to site boxes for cavity nesting birds such as blue and great tits away from prevailing winds, and with a direct flight path to some tree cover. We attached them securely to the wall, approximately 2m off the ground – this is high enough to prevent interference but close enough to reach for monitoring and maintenance. We have put them as far apart as possible from each other and out of the sight of our bird feeder around the corner. We think that it may be unlikely that tit species would nest that closely to each other but if the boxes are occupied by house sparrows then these two boxes could form the start of a colony.

Connecting up the cameras

The IP Nest Box Camera connects via Ethernet cable directly into a router, hub or switch and then you need to choose software to allow you to access the camera feed and live stream to a website. We are currently trialling Anycam.iO. If there is no WiFi network, the WiFi camera can be used as a standalone WiFi source that you connect to directly with your smartphone or tablet. Alternatively you can tether the WiFi camera to your existing WiFi network and access it as a node on the network. The WiFi camera is viewed via an app on your smartphone or tablet and we are currently trialling ICSee Pro.

The current view in the IP camera nest box

Now we just have to wait and hope that the local birds decide that these are desirable nesting sites! For further advice on nest boxes and cameras, please do not hesitate to contact our team of Wildlife Equipment Specialists.

Red Sixty Seven: A Collection of Words and Art Inspired by Britain’s Most Vulnerable Birds

Red Sixty Seven features our most vulnerable bird species, beautifully illustrated by some amazing wildlife artists. All of the publishers profits from the sale of this book will be donated to BTO and RSPB to further their work on red listed birds.

Contributors include Chris Packham, Ann Cleeves, David Lindo, and Patrick Barkham.

This book should not exist.

In an ideal world this book, and the official Red List of the most vulnerable birds in the UK it is based on, would not be needed. But the world is far from ideal and our bird populations are declining at an alarming rate. In the past few years alone the once widespread Wryneck has ceased breeding in the UK altogether and has dropped off the list completely. Which species will be next?

Editor, Kit Jewitt has taken some time to answer a few questions about the Red Sixty Seven book project and the list itself.

Of all the birds on the Red List which do you think is most vulnerable?

If I had to choose one, it would be the Hen Harrier. Not only do they have to deal with all of the natural challenges they face, they also have to contend with persecution from criminals within the grouse shooting industry, which evidence now suggests is the main cause of their decline in numbers. The fact that 72% of tagged Hen Harriers are confirmed or considered likely to have been illegally killed is a national disgrace. However, in terms of the recent rate of decline I would also suggest Turtle Dove is a species of highest concern.

Many people will be surprised to see herring gull on the list, could you expand on how this seemingly ubiquitous bird has made the list?

Herring Gull populations in coastal areas have dropped by over 50% in my lifetime. This is largely due to the lack of food at coastal sites, with overfishing of UK coastal waters and warming seas caused by climate change likely to be the main reasons for the reduced amount of food available to gulls and other seabirds. They are adaptable, intelligent birds though, so moving to inland areas, or areas where humans create waste for them to eat has been a way for some populations to survive.

Have any birds managed to move away from the Red List to Amber over the last year or so, and which birds are the most recent additions?

Nineteen species were added to the red list for the first time when it was last updated in 2015, and one species, Merlin, moved back onto the list. Breeding seabirds, such as Puffin, Kittiwake and Shag are now included, and with the additions of species such as Woodcock, Nightingale and Pied Flycatcher there are now more woodland birds on the list than any other habitat. Two species, Bittern and Nightjar, have moved from the red to amber lists thanks to the creation and management of suitable habitat, stimulated by species action plans.

We know how we as individuals can help garden birds, but the list contains a high proportion of iconic water birds. How can we as individuals help preserve the many waders and ducks that are on the list?

Many projects being conducted by BTO, RSPB WWT and others help waders, seabirds and ducks, so fundraising for these is vitally important. My main motivation behind the Red Sixty Seven project was to do something to help these declining birds, by spreading the word and raising money for conservationists on the ground. By highlighting the red list far and wide, more people will care and will then hopefully start their own fundraising for BTO’s Operation Wader or Curlew appeal, or WWTs Black-tailed Godwits appeal, or whichever scheme chimes with them. I can’t run marathons or undertake extreme endurance like my friend Jonny Rankin, who has raised over £19,000 for Turtle Doves, so I had to think of a different way of fundraising!

Farmland bird species also make up a large part of the list. Can you see any hope for securing the future of our most rapidly declining farmland species?

The change in farming and land management practices over the last 40 years, including the use of pesticides and changes in crops grown have ultimately reduced the amount of appropriate habitat, and food sources for our farmland birds. Post Brexit, there is an opportunity for the government to make changes to policy to help our farmland wildlife. I just hope they take full advantage of it.

We love the idea of using the power of beautiful words and paintings to deliver a conservation message. Do you think that engaging the reader emotionally can result in more concrete conservation actions being taken?

I hope so! As well as raising funds for crucial work to help red-listed species, I hope Red Sixty Seven brings the list and the plight of these birds to a wider audience, inspiring other people to take action themselves, whatever that might be. The artwork and stories within the book bring home the message in a very accessible way, and you are left under no illusion that we must do something. There is a poignant sting in the tale at the end of the book; an ‘In Memoriam’ section devoted to the birds we have lost as breeding species in recent years. This book is a call-to-arms.

All of the publisher’s profits from the sale of this book will be donated to BTO and RSPB to further their work on red listed birds.
