BCT Big Bat Skills Workshop 2021

On Friday 12th February the Bat Conservation Trust held their Big Bat Skills Event, which was run online via Zoom and breakout sessions. We were lucky enough to attend several sessions including the Introduction to Kaleidoscope for Bat Analysis run by Wildlife Acoustics – where we learned more about the many uses of Kaleidoscope software, Titley Scientific’s session on their product range and Anabat Insight software, Thermal Imaging by Dr Kayleigh Fawcett Williams and Emergency Bat Care for Ecologists by Maggie Brown. We cover a couple of these in a little more detail below.

We joined the session on thermal imaging run by Dr Kayleigh Fawcett Williams to learn more about how this equipment is being used in ecological consultancy. Most participants were new to thermal imagery, so Dr Fawcett Williams walked us through the basics. She explained that thermal imaging works by picking up thermoelectrics from the environment – infrared radiation, meaning that it is not at all invasive to the animals as the scopes emit no light (as opposed to night vision cameras that use infrared to light up the subjects).

Dr Fawcett Williams went through the benefits and applications of thermal imaging, and provided this helpful link to a copy of her Thermal Imaging: Bat Survey Guidelines published in association with the BCT.

The benefits of this survey method were explained, including: ability to use at all times of day and for long durations and cost effectiveness due to lack of man power needed. Thermal imaging can reduce the risk of false positives when it comes to identification of species and also provide a wider picture of landscape or infrastructure use by illustrating patterns of activity. She also highlighted that it is good for multidisciplinary work (e.g. for firms that work with engineers) as it has a range of applications that are not just ecology based.

Dr Fawcett Williams explained the difference between using thermal imaging as a survey ‘aid’ – assisting normal survey work, with live results, usually with lower end equipment; and using it for the entire survey ‘method’ – where higher accuracy is needed and results are analysed at a later date. When surveying for bats, Dr Fawcett Williams recommended using static detectors alongside thermal imaging but noted that the thermal imaging devices have a much longer detection range than static detectors and will pick up more than the static detectors. It is also vital that the time stamps of both devices are lined up so that they are able to be used in unison.

She also made sure to comment that thermal imaging devices cannot see through solid objects but pick up heat patterns which can often be things other than your target species (such as moisture). Thermal imaging is designed to be used for active animals and is therefore not recommended as a replacement for surveys such as internal roost surveys, especially as thermal imaging devices cannot pick up torpid bats.

It was then time to move onto the next session: Emergency Bat Care for Ecologists by Maggie Brown. This session focused on what to do if you came across an injured bat during an ecological survey.

She explained that bats are protected by law and that while only licensed individuals should be in contact with bats, first aid is considered emergency care and so this can be administered without a license. That being said, you will need to be able to justify any contact you have had with a bat so she strongly suggested that you keep records of the encounter.

Reasons that you would have to perform emergency care for bats were covered, such as when the individual is:

Exhausted or disoriented
Trapped and prevented from returning home
Too badly injured to fly and return home
Disturbed or have lost their roost
A flightless baby and has little or no fur; undeveloped wings but oversized thumbs and toes

Helpful equipment in an emergency bat care kit

She covered how to know when a bat needs food, how to feed them and how to recognise and deal with dehydration. Great emphasis was placed on the fact that you should always wear gloves for any contact with bats due to the potential risk of them having a strain of rabies (EBLV), and that for this reason some vets may refuse to treat them. It is very important to recognise how much care you would be able to provide yourself and when it is best to pass the care onto a long term bat carer or enlist the help of a vet.

If you think that you may end up in a situation where you need to administer emergency bat first aid, I would highly recommend attending one of Maggie Brown’s very informative sessions and, when possible, formal training.

The BCT website is also a useful resource, offering advice on emergency bat care and providing information about the opportunities available for those looking to volunteer.

Overall, the day was very interesting and educational, and it was nice to see such a range of skill sets attending the workshop as well as the enthusiasm shared by all.

The RSPB Big Garden Birdwatch 2021

The 29th-31st January marked the 42nd Big Garden Birdwatch. This citizen science survey asks members of the public across the UK to count the numbers and species of birds that land in their gardens in a one hour period. In 2020 almost half a million people took part and 7.8 million birds were counted.

This year, the RSPB launched the Big Garden Birdwatch Live to run alongside the counts. A full weekend of live events including interviews and Q&As with Nick Baker, Chris Packham and a host of RSPB staff members. Bird feeders from nature reserves around the country were live streamed throughout.

At NHBS more of us than ever decided to take part and record the species that visited our gardens. Some of us were luckier than others; with weather warnings across Devon it was a wet and windy weekend. Despite the conditions we were treated to some wonderful sightings and as a group spotted 23 different species.

Overall a much higher number of pigeons and corvids visited our gardens than in previous years, as it seemed these larger birds were the least phased by the rain. Long-tailed tits and blue tits were the most highly spotted passerines.

See our results below:

Nigel

Nigel’s three children assisted with his survey and helped identify a great range of species.

3 Blue tits
3 Tree sparrows
2 Carrion crows
2 Blackbirds
2 Dunnocks

8 House sparrows
2 Feral pigeons
1 Common gull
1 Magpie

Phoebe

Phoebe’s family had the highest quantity of birds visit their garden, an impressive 26 individuals. Her sister Amabel even managed to take this beautiful photo of a Great spotted woodpecker.

8 Long-tailed tits
5 Blue tits
2 Chaffinches
2 Coal tits
2 Nuthatches
2 Great tits
1 Woodpigeon

Oli

Oli’s garden seems to reliably attract corvids and pigeons, as he counted very similar numbers to his 2020 survey.

3 Woodpigeons
2 Carrion crows
2 Jackdaws
1 Robin

Antonia

Antonia was treated to a large flock of jackdaws. She also saw a grey wagtail – a species more fond of riverside habitats, although they do tend to venture further during the winter.

10 Jackdaws
2 Blue tits
2 Magpies
1 Robin
1 Goldcrest
1 Grey Wagtail
1 Blackbird

Gemma

Living in the centre of town led to my own list being dominated by relatively urban species.

11 Feral pigeons
5 Herring gulls
2 Carrion crows
2 Jackdaws

Across our 8 gardens we counted a total of 117 birds across 23 different species.

Congratulations to all the individuals and organisations nominated for this year’s CIEEM Awards – we wish you all the best of luck with your endeavours during 2021.

CIEEM Autumn Conference 2020: Time to Change

CIEEM’s “Time to Change: Putting the Environment at the Heart of Social and Economic Wellbeing” conference was accessed remotely, like so many of our gatherings this year. The virtual platform was used with great ease, allowing many people to access the talks which seamlessly focused on the various key speakers. The day also included live Q&As and breakout rooms, with all sessions ending in lively panel discussions. The conference took place over three days and focused on six different sub-topics. The general theme was ‘The Future’; how best to arm ourselves and the importance of collaboration, including people from all sectors and the general public.

At NHBS, we were particularly interested in the ‘New Tools and Technology Advancing Professional Practice’ session that was held on the final afternoon. This session covered Artificial Intelligence (AI), remote sensing and soundscape ecology, and explored the best methods of using the information that these technologies provide us with.

Tom August (UK Centre of Ecology and Hydrology) took us through how AI can learn when being used for species identification. It can also be a great tool for involving the public in research and an aid to improving our own identification skills. He discussed how we can help encourage technology learning by making positively identified photographs attached to species ecology widely available. He also assured us that AI is continually learning and improving: for example in 2014 AI could identify species to the same level as an average skilled person, whereas by 2017 it could function to just below the level of a species expert.

Jonny Miller and Joshua Aves (WSP) then took us through a working example of using drones and camera footage alongside GIS to improve survey and analysis efficiency (in this example up 70%). They explained that this can be great for creating baseline information and can help with safety when surveying more dangerous areas such as roadsides. They anticipate that the use of this technology will increase due to new needs to demonstrate biodiversity net gain.

Oliver Metcalf (Manchester Metropolitan University) demonstrated the use of audio recording devices to survey for various species and the benefits thereof. These benefits included removal of the surveyor effect on the target species’ behaviour as well as being able to analyse the same recording multiple times, in different ways and by different people – this helps to reduce error and increase the number of target species. When used in areas with reduced sight it can also be more productive than traditional visual surveys. His talk covered the drawbacks of the method, for example, there is no rule book around this technology, and if there is a loss of data then it is a big loss. At the moment, the technology is biased towards birds, and although large amounts of data are produced (which in itself has its benefits and challenges) there is not yet a wide database for all species. However, automated functions such as species identification and identifying false positives are continually improving. Oliver went on to explain that the use of acoustic indices does not require a high level of skill and has a huge variety of applications such as habitat type prediction (which maps well onto wilderness perception), variation in sound bar correlating to species richness, and detection of temporal trends.

As the use of all of these technologies result in large databases, Gregory Slack and Matthew Whittle (Jacobs UK Ltd) took us through a working example of how much data to collect at a site survey for bats and how to analyse it. They explained that there is a need to collect data with deeper analysis reporting more than means and medians (and believe this will be reflected in new guidelines) but that with use of acoustic recorders and statistical software such as R, minimal added survey effort does not add much when it comes to analysis, as this can be automated. Analysis like this can also be used throughout the study rather than only at the end.

The overarching takeaway from this session was that we should embrace the use of new technologies and that we all have a part to play in helping to develop them. There were discussions as to whether these new technologies would replace us (ecologists) but all speakers were reassuring that they would only make our lives easier. There was emphasis that their use should be carried out by (or at least alongside) ecologically trained professionals to provide meaningful data.

All of the talks from this inspiring session left me excited for the beneficial impacts of new technology.

Bat Detecting for International Bat Night

The weekend of the 29^th-30^th August was the 24^th International Bat Night. Organised by Eurobats, this annual celebration of bats saw events taking place all around the world in an effort to educate and inspire people about these fascinating flying mammals.

To mark International Bat Night, a small team from NHBS ventured out to an area of local woodland with a selection of bat detectors. The site we visited has been managed for the past two years by Steve and Tamara Davey, with the aim of maximising biodiversity. They are also ensuring the continued provision of habitat for certain species including seven recorded bat species, Nightjars and Woodcock. (Read more about how they are supporting nature in our recent interview or on the Woodland Wildlife website).

We arrived at the woods just before 7pm and were treated to a brief tour of the woodland as the light faded. Steve showed us the areas where the conifer plantation had been thinned, allowing more light to enter. In these areas there have already been increases in native plants and there were many seedlings present from native trees. He also showed us where he had planted a hedgerow boundary, with the intention of creating more commuting corridors for both bats and other wildlife. The second part of the woodland consisted of immature sitka spruce trees, some of which have now been cleared to make way for native trees, shrubs and plants.

In the two years that Steve and Tamara have been managing the site, the biodiversity of the plot has increased and the area is abundant with birds, small mammals and insects. Following advice from the Devon Greater Horseshoe Bat Project, they have also created three ponds, and this is where we spent most of our time on International Bat Night.

We used a selection of bat detectors including the Song Meter Mini static recorder, which was useful as it could be left to record while we kept our eyes on the skies watching bat movement and behaviour. We also used some handheld detectors including Magenta Bat 5s, an Anabat Scout and an Echo Meter Touch 2 which was extremely popular with the group due to the visual representation of the sound along with the incredibly useful auto-ID function.

During the evening we detected common pipistrelles, soprano pipistrelles, Noctules and Leisler’s as well as a suspected Nathusius’ pipistrelle and a Barbastelle that are awaiting ID confirmation from recorded files. Although the night was chilly, there were lots of moths and other flying insects that the bats were feeding on, and we enjoyed listening to pipistrelle feeding buzzes and watching them hunt and catch insects above us in the tree canopy.

The evening was extremely enjoyable and it was a great opportunity to see the work that Steve and Tamara have been doing on their land. The range of bat species we heard is testament to the quality of habitat that they have created and it was a great place to celebrate the 2020 International Bat Night.

CIEEM Online Conference Review

CIEEM’s summer conference this year discussed the urgent need to address the interlinked climate emergency and biodiversity crisis for the sake of the planet, the species and habitats it supports and for future generations. Due to lockdown and social distancing restrictions, the conference took place online, with speakers and participants attending from their homes via Zoom.

Wildlife Equipment Administrator Claire Graham attended the conference and has summarised her experience of the event and the talks below.

Logging into Zoom to take part in my first online conference, I couldn’t help but wonder if this is going to be the future of large events for a while… But, given the topic of the CIEEM conference ‘Climate and Biodiversity Crises: Professional Approaches and Practical Actions’, maybe there are positives to this! Certainly, creating a way to hold important conferences, without the need for everyone to have to travel (often long distances by plane or car) has its upsides.

So, with everyone speaking and listening from home, the day began with an introduction from Max Wade, the president of CIEEM. Following a quick mention of the unusual circumstances being dealt with by everyone this year and a reference to the growing importance of issues such as climate change and biodiversity loss, it was time for the first talk.

Diana Pound from Dialogue Matters opened with the keynote presentation: ‘Seize this Moment and Get Fresh Momentum’. She took us straight into a positive and inspiring talk, encouraging people to shift from an attitude of fear and doubt to one of optimism and hope. Diana asked us to highlight strengths instead of problems in conversations and dialogue, as a more effective way of motivating people to change, rather than focusing on everything that is being done wrong. Diana stated that the world is starting to wake up and a recent survey showed that 97% of those surveyed thought climate change was serious and 70% thought it was very serious. It also showed that 77% of people believe we should make as many lifestyle changes to stop climate change as we are doing to stop Covid-19. Overall, we were reminded to remain hopeful and be inspired to action; a quick poll demonstrated the power of this.

This led us into the next talk by John Box (from the CIEEM Action 2030 group) which discussed the actions that CIEEM are taking to deal with the interlinked climate emergency and biodiversity crisis. He provided lots of advice about offsetting carbon emissions and explained that CIEEM aim to achieve net zero carbon emissions in all its activities by 2030. John also emphasised the importance of environmental organisations sharing knowledge and building relationships.

Penny Anderson (a member of the Action 2030 group and Ecological Restoration and Habitat Creation SIG) followed with a talk about ‘Habitats and Carbon, Storage and Sequestration’. She explained that, to meet the latest 2050 net zero target, the Committee on Climate Change have recommended tree planting, peatland restoration and green infrastructure. Penny explained that around half of emissions from human activity are absorbed by land and oceans and the rest in the atmosphere. Surprisingly, there is globally 3-5 times more carbon in soils than in vegetation and 2-3 times more than in the atmosphere. All semi-natural habitats hold more carbon than arable or improved grassland and these types of habitats are also better for biodiversity. Therefore, we need to concentrate on diversity within habitats and not just think about trees; there is a simultaneous need to protect remaining habitats and minimise losses in soil while also undertaking habitat creation or restoration.

The next talk was by Ben McCarthy, the Head of Nature Conservation and Restoration Ecology with the National Trust. He explained the role the National Trust are going to play in the climate change and biodiversity crises, as well as the challenges they face as the largest land-owning NGO in Europe. Ben explained the organisations plan to repurpose farmland and create 20,000ha of new woodland and 25,000ha of new priority habitat, including restoring peatlands – a big challenge, but one they are determined to achieve! The National Trust recognise the significance of their land which is home to 44% of UK species including 737 that are threatened with extinction. Half of their properties have priority habitats that are highly sensitive.

Continuing on the subject of peatland restoration, the next talk was by Clifton Bain from the IUCN Peatland Project Programme. His talk on ‘The Peatland Code: Business Funding and Environmental Assessment’ discussed the importance of peatlands and their many benefits and gave an overview of the Peatland Code. The Peatland Code is a voluntary certification standard that helps to gain funding for peatland restoration projects by giving assurance to buyers; they fund the projects in exchange for climate benefits and mitigation. He compared the ecosystem services in healthy vs damaged peatland and discussed how damaged peatlands emit carbon rather than acting as a carbon sink. He also mentioned the loss of unique biodiversity that comes with damaged peatlands.

After lunch we jumped back into the next talk with Richard White from NatureBureau with his fascinating talk ‘Blue Carbon – The Sea, the Coast, and the Climate Crises’. Richard discussed ocean warming and acidification, sea level rise, shifting species distribution and methods of mitigation. He reviewed the role that ocean and coastal ecosystems have in the carbon cycle and the link between protecting and restoring marine biodiversity and mitigating our carbon emissions. Seagrass beds and saltmarshes act as globally significant carbon stores but only 21% of these habitats are currently protected by our Marine Protected Areas (MPAs). There is a need to work to protect these habitats and support restoration projects.

Richard Lindsay from East London University continued with more information about the importance of peatlands with his talk ‘Peatland Restoration and Carbon: Sphagnum, Carbon and Timescales’. He advised that, despite many peatlands and blanket bogs being damaged and emitting carbon, restoration projects can sometimes be challenged as successful carbon mitigation due to them being thought of as slow-growing systems. However, Richard discussed the use of adding Sphagnum to peat restorations due to it being a significant carbon sink and advised that it can be grown rapidly in optimum conditions.

The next talk was David Holland from Salix on ‘Soft Engineering Approaches to River, Wetland & Swale Projects’. He talked about the high carbon cost and negative ecological impacts of traditional hard engineering techniques and discussed low carbon solutions that can be used instead. Using natural materials and processes, rather than materials such as concrete, rock or metal, generates less waste, needs less future maintenance and improves the water quality and habitat, as well as providing vegetation that will continue to absorb carbon and benefit the environment.

The closing talk of the day was by Lee Dudley, Head of Environmental Carbon with the Woodland Trust and focused on ‘Carbon and Woodland Creation’. He explained that the Woodland Trust aim to conserve, restore and re-establish trees; their vision is a UK that is rich in native woods and trees for wildlife and people. The fact that woodland creation is now being recognised as a cost-effective method of climate change mitigation enables the potential for more woodland creation projects. Lee also discussed the importance of matching the right species to the right sites for the best outcomes and reminded us that it is not just about trees, but about the whole environment.

The day was wrapped up with a quick conclusion from David Parker from CIEEM. He thanked the speakers for all their extremely important and interesting talks and with that the event was over. My first experience of an online conference was positive all round; the talks were fantastic, and everyone enjoyed them from the comfort of their own homes with few technical difficulties. Hopefully the next conference can be attended in person but, if not, this experience has demonstrated there are definitely ways to keep talking and learning about these important issues.

30 Days Wild Activities – Hedgehog Watch

Hedgehogs are abundant in urban and suburban areas and can frequently be found in gardens, as these provide safe, accessible spaces for them to forage and rear their young. They are most active between April and September with the main mating season occurring between May and June. Female hedgehogs give birth during June and July, although some will go on to produce a second litter later in the summer. All of this means that now is a great time to look for hedgehogs – and if you’re taking part in the Wildlife Trusts’ 30 Days Wild Challenge, then this will also contribute to your month of wild activities.

If you’re lucky enough to have hedgehogs in your garden, why not take the time to record their behaviours for Hedgehogs After Dark. This project, organised by Hedgehog Street, aims to learn more about the ways in which hedgehogs are using our gardens and the behaviours that they are showing through the spring and summer. Until Sunday 26th July you can submit your observations to their website and have the chance of winning an exclusive hedgehog hamper in their prize draw. Visit their website for lots of information about the different behaviours they are interested in and how to submit your findings (you will need to register as a Hedgehog Champion to do this).

Keep reading for some top tips on making your garden attractive to hedgehogs and how to watch them, either with or without a trail camera.

Is your garden hedgehog friendly?

There are several things that you can do to make your garden more attractive to hedgehogs:

• Improve access – Gardens are only useful for hedgehogs if they can access them. Plus, hedgehogs move long distances throughout the night to find enough food, so creating networks of gardens that they can move between is important. By cutting a 13cm diameter hole in the bottom of a fence or removing a brick from the base of a wall, you can help to provide access and link your garden with surrounding ones.

• Provide shelter – Try to keep some areas of your garden wild and overgrown, as this will provide secure nesting and feeding spaces. An artificial hedgehog home will also provide a safe and warm space for hedgehogs to overwinter and for a female to birth and raise her young in the spring and summer. Try not to use pesticides or slug pellets in the garden, as these are poisonous to other animals as well as slugs.

• Provide food – Make sure that there are lots of worms, beetles and earwigs in your garden by growing wildflowers and providing log piles. Leaving areas of the garden which are overgrown or making a small wildlife pond will also help to encourage a diverse range of invertebrates. (Make sure your pond has sloping sides or piles of rocks to allow any animals to escape.) You could also provide a shallow dish of fresh water along with good quality hedgehog food, meaty dog or cat food, or dry cat biscuits.

Tips for watching hedgehogs

Hedgehogs are nocturnal, so the best time to watch them is during late evening. Throughout the night they can travel up to 2km searching for food and/or mates. (This great video shows radio-tracked hedgehogs moving between gardens in a suburban area of Brighton). If you have a suitable window looking out onto your garden, then you can watch them from the warmth of your home. Make sure that you turn any inside lights off and keep noise to a minimum. If there is no illumination from street lights, visibility will be best at twilight (before complete dark) and around the time of the full moon (provided it isn’t too cloudy).

If you can’t watch the garden from a window, then wrap up warm, get into stealth-mode and venture outdoors. As with any wildlife-watching endeavour, the most important thing is to be still and quiet. It might also help if you can get low to the ground which will provide a hedgehog-level view of their activities. Don’t be tempted to try to get too close to them, however, and never attempt to pick them up or interfere with their natural movements.

Using a trail camera to watch hedgehogs

One of the best ways to view the hedgehogs in your garden is using a trail camera. If you’re lucky enough to own one of these, then setting it up to record at night is a great way to see if any hedgehogs are around and, if so, what they’re getting up to. Here are some tips to maximise your chance of getting great footage:

• When siting your camera, think about where the hedgehogs are likely to be moving around. If you have a hole cut in your fence and you know that hedgehogs are using it to access your garden, then you might want to point your camera towards this. Similarly, if you have provided any food or water, then setting your camera up near to this is a great way to capture footage of them feeding.

• Position your camera low to the ground. Think about the size of the hedgehog and where it is most likely to trigger the infrared beam.

• Set your camera to the highest sensitivity setting. If you find that it is triggering far too much, particularly in the absence of any animals, then you can always reduce this later.

• As you’ll be recording hedgehogs mostly in darkness, having a camera with invisible night vision LEDs could be a bonus, as these will not startle the animals. Plus, models with adjustable night-time illumination (or which adjust automatically) will give you the most control over your image quality.

[The Browning Strike Force HD Pro X is one of our bestselling trail cameras for hedgehog watching and is used by lots of great projects, such as London Hogwatch. For more information or advice about trail cameras, please get in touch with us and chat with one of our experienced ecologists.]

No hedgehogs?

Maybe you don’t have a garden, or you have one but haven’t seen any hedgehogs using it. You can still view lots of great hedgehog videos on the Hedgehog Street YouTube channel. Or, if you use Facebook, why not watch this talk by ecologist and hedgehog fan Hugh Warwick, recorded for the Summer Solstice ‘Wonderland’ Festival this spring.

30 Days Wild Activities – Bat Walk

The hours around sunset are the best time to see and hear bats. Image by O Haines.

Looking for some inspiration for activities during 30 Days Wild? Why not take a stroll around sunset and see if you can find some bats. If you have a bat detector then you can also listen to the ultrasound calls they produce and have a go at working out which species you’re seeing and hearing. Plus, an evening walk also gives you a chance to see what other nocturnal animals are out and about – owls, foxes, badgers and toads are all more active at night and, if you’re lucky and in the right place, you might also be fortunate enough to hear a Nightjar.

What you need:

The Echo Meter Touch 2 connects directly to your phone or tablet.

• Bat detector – For beginners, a heterodyne detector is a great choice as they are economical and easy to use. Simply tune it to the frequency that you want to hear and then listen through the speaker or with a pair of headphones. If you want something a little more advanced, the Echo Meter Touch 2 connects directly to your phone and lets you view and record the bat calls, as well as suggesting the most likely species that you’re listening to. (If you don’t have a bat detector, you can still go for a walk at dusk and look for bats flitting beneath the trees and across the surface of the water).
• Torch – Not for seeing the bats but for finding your way safely in the dark!• Warm clothing and sensible footwear – Make sure you have enough warm clothes for when the temperature drops after sunset, and footwear that’s suitable for the chosen terrain. A thermos with a hot drink is also a good idea!
• Guide to bat frequencies – If you’re less familiar with bat detecting then a list of the frequencies at which you are most likely to receive the strongest signal for each species is a good thing to have with you. This simple pdf can be printed out to carry with you, or why not take a look at this guide from the Bedfordshire Bat Group for more detailed information on identifying bats using a heterodyne detector. The FSC Guide to British Bats is also a good choice and provides lots of information on identifying bats in flight.

When to go:

Bats are most active from April to September and the best time of day for seeing and hearing them is around sunset. If you’re walking to a location where you will be using your bat detector or hoping to see bats, then make sure you set off with plenty of time to get there before the sun sets. And don’t forget your torch – even though it will be light when you set out, you’re likely to need it on the way home.

Where to go:

Woodlands, parks and gardens are all good spots to look for bats. Image by O Haines.

Parks and woodland, especially those with aquatic areas such as ponds and lakes, are great places to find bats. If you can find a walk that covers a variety of habitat types then this will increase your chances of seeing/hearing more than one species. Make sure that the route you choose is safe and accessible and that you know where you’re going – places can look very different at night than they do in the day and it’s easy to lose your sense of direction if you’re not on a clearly marked path.

If you don’t want to venture far from home, then you can also look and listen out for bats in your garden. Near hedges or trees is usually a good place to focus your attention.

What to do:

The Magenta Bat 5 is ideal for bat walks

Once sunset is approaching, simply turn your bat detector on, keep as quiet as you can and watch and listen for any bats. The earliest species to emerge tend to be the pipistrelles and noctules. Of these, common and soprano pipistrelles are the most frequently seen. For this reason, it is worth setting your detector to 45 or 55kHz (or switching between the two periodically) to see if you can pick up any sounds. If you can see bats flying but don’t hear any sounds at these frequencies, then try scanning through all frequencies slowly to see which produces the most significant and clear response.

If you are near water and see bats skimming the surface, then these are likely to be Daubenton’s bats. As with the common pipistrelle, Daubenton’s bats produce the strongest echolocation signal at around 45kHz. (They also tend to emerge later than pipistrelles, so you may have to wait until later in the evening to catch a glimpse of these!).

Once you become used to using your detector, you will become accustomed to the different types of noises produced by different species and, in combination with where and how the bats are flying, will become more confident in deciding which species you are looking at and listening to.

Find out more:

If you want to find out more about bats, the Bat Conservation Trust website is a great resource and offers information on all 18 species of bat found in the UK. They also provide a list of local bat groups and coordinate the National Bat Monitoring Programme. Surveys cater to different levels of experience and knowledge and are fun and rewarding to carry out. Some don’t require any equipment, so you can take part even if you don’t own a bat detector.

The RSPB website is a great place to hear common bird songs and will help you to distinguish between different types of owls. The most common species you are likely to come across are Barn Owls and Tawny Owls. You can also hear an example of a Nightjar call on the website.

30 Days Wild – Our local wildlife photos

Throughout June, thousands of people will be taking part in The Wildlife Trusts’ 30 Days Wild. Designed to improve our health and wellbeing, as well as being good for the planet, this annual challenge tasks us to do one wild thing a day for the whole month. Sign up on the Wildlife Trusts website and receive a free downloadable pack of goodies to help you plan your activities.

Here at NHBS we rarely need an excuse to get outside for a spot of wildlife watching. And as lots of us are currently working from home, we’ve been enjoying the opportunity to take stock of the nature that’s much closer to where we live. We’ve also been sharing our wildlife photos, all taken in gardens or on local walks. Scroll down for some of our favourites from the past month.

Why not let us know in the comments about what activities you get up to in June – we’d also love to see some of your photos!

Oli has been busy in the garden with his moth trap – a recent catch included this oak beauty, a couple of early greys and a stunning puss moth. A felt refuge tile also attracted a lovely group of slow worms.

While dismantling an old shed in her garden, Natt discovered this cheeky creature. She also captured an image of a vibrant brimstone moth.

Toby came across this group of hungry mouths in his stables.

Phil was excited to see that his solitary beehive had attracted some inhabitants.

After creating a hole in his fence to help hedgehogs move from garden to garden, Paul was rewarded with this welcome visitor. (With drastic reductions in road traffic, hedgehogs are one of the species that are expected to be benefiting from the lockdown!)

Chris discovered this nest, packed with eggs.

Luanne caught some great moths in her garden in north Wales – including this eyed hawk moth and buff tip.

Tabea took this lovely picture of a stonefly while on a local walk.

Angeline captured some great images of insects enjoying the local flora.

Nigel found this tiny slow worm in his garden and also discovered a bumblebee nest in his compost bin.

While working from home, Elle has been enjoying watching the birds visiting her collection of feeders.

Finally, Guy captured this charismatic shot of some of the frequent visitors to his local rooftop.

Have you spotted anything exciting in the garden or while on walks this spring? If so, we’d love to hear about it and to see your photos!

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.

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.
