A Bat-tastic Day at Duddon St Peter’s Primary School!

On Wednesday, we - Prof Tessa Smith, PhD student Lucy Morison, and Dr Camilla Soravia - ventured out of our lab to visit Duddon St Peter’s Primary School, hoping to bring our passion for bats to the children at school. We were greeted with a lot of enthusiasm and countless raised hands, which made it an amazing morning for all of us!

Why Bats Are Nature’s Heroes

We gave four talks to children aged 5 to 11, highlighting why bats are vital to ecosystems and the planet and introducing their unique traits.

The children learned that bats:

• 🦟 Control insect populations, acting as natural pest controllers.

• 🌸 Pollinate flowers, supporting biodiversity.

• 🌱 Disperse seeds, helping plants grow in new areas.

• 👨‍👩‍👧‍👦 Are amazing parents, caring for their young.

• 💞 Are social creatures with lots of friends.

  
  

Exploring Echolocation and Conservation

For the older children (aged 7 - 11), the team delved deeper into bats' incredible ability to navigate in darkness using echolocation. The children also discussed threats that bats face, including increased light and noise pollution, and habitat loss, learning simple ways to help protect these remarkable animals.

Hands-On Creativity

To round out the day, the children channelled their enthusiasm into creative activities:

• ✂️ Making their own origami bats.

• 🎨 Following a step-by-step guide to draw a bat.

These activities sparked discussions about the anatomy of bats and gave us all a chance to put our craft skills to the test!

Inspiring Future Scientists

It was a privilege for our team to visit Duddon St Peter’s Primary School and inspire the next generation of scientists and conservationists. Changing perceptions about bats and fostering a sense of curiosity and care for wildlife is crucial to their protection.

A big thank you to Duddon St Peter’s Primary School for welcoming us and to the children for their enthusiasm and curiosity. We are also grateful to our supporters, including the Leverhulme Trust and the School of Natural Sciences, for making this outreach event possible.

What’s Next?

We hope this visit will cultivate a lifelong interest in wildlife conservation among the children. After all, the future of our planet rests in the hands of these young minds.

From field to lab: A successful first season studying bats

We have now officially concluded the first field season!! These months have passed in the blink of an eye. We have spent our time driving around the stunning landscapes of North Wales to collect environmental data and faecal samples at each bat roost. We have also installed recorders and cameras under where the bats were resting during the day so that we could monitor their behaviour for the following months.

We did not lack adventure – occasionally we had to climb ladders or silently crawl in dark attics while collecting faecal samples under the dim red light of our torches so that we did not scare the bats. During our brief visits inside the maternity roosts, we had a chance to witness the important stages of the bats’ breeding cycle. First, fluffy and round pregnant females in May, then tiny pups clinging to their mothers in July. Since then, the pups have learnt to fly and have become independent.

Now, the adults are mating again and slowly starting to hibernate. The females will store the sperm throughout the winter and will then become pregnant again in the following spring.

While the bats wait for winter to pass in their hibernation roosts, we will also stay indoors in our lab at the University of Chester, where we will work to process faecal samples and analyse footage and recordings. The season has been a success, so we have a lot of data analysis ahead of us! We have now collected 300 faecal samples and 40 urine samples and almost 300 hours of footage and ultrasound recordings. We have also collected over 20 days and nights of environmental data – light and noise pollution – for each of the ten roosts that we are monitoring.

So, what will we analyse?

We are in the process of detecting and quantifying cortisol, which is considered a ‘stress hormone’ in bats, so that we can then determine if bats in some roosts are more stressed than in others. Since we know that many bat species avoid bright and noisy areas when they look for prey at night, by pairing noise and light levels at the roost entrance with cortisol, we will then be able to determine whether light and noise pollution are indeed causes of stress to the bats. We will also use our footage and recordings to discover what the bats do during the day at the maternity roosts, how they communicate with each other, and when they decide to leave the roost each night to find prey.

We will then be able to see if bats at roosts with more light or noise pollution behave differently, and whether this altered behaviour might indicate stress. We hope that this research will help us to understand what we can do to improve the welfare of our bats.

Now that the first field season is complete, we would like to thank the incredible people that continue to take care of bat roosts at their property and have enthusiastically welcomed us and our research, as well as the fantastic volunteers that gave up some of their time to accompany us on field trips. We also thank the Vincent Wildlife Trust and Natural Resources Wales for their continuous support. We are now ready to dive into the many hours of video recordings and lab work needed to analyse our data until we can see the bats again in the next field season.

Unlocking the Secrets of Lesser Horseshoe Bat Health: Data Collection Begins!

Embarking on an exciting milestone in our study, our team has initiated data collection at multiple Lesser Horseshoe Bat roost sites across North Wales!

Earlier this month, we began the collection of various types of data at our selected LHB roosts. This stage of the BATMAN project comes after months of meticulous planning, developing methodological approaches to maximize data collection while minimizing disruption to our winged subjects! For faecal sample collection, innovative devices have been created which will allow large numbers of samples to be collected over both 24 hour periods, and 1 month periods. Concurrently, we've initiated the gathering of environmental data, ranging from temperature and humidity within the roosts to sky luminance outside. On top of that, cameras and ultrasonic microphones have been placed in the roosts, so we can not only see the behaviours of the bats, but also hear what they are saying!

But what are we hoping to do with all this data?

Soon, our focus will shift to the lab, where we'll meticulously analyse the faecal samples, primarily examining levels of cortisol and corticosterone, commonly known as "stress hormones." Through this analysis, we aim to gain insights into the overall welfare of each roost. Subsequently, we'll correlate this information with environmental data to assess the impact of various factors on roost health, while behavioural data may illuminate indicators of stress.

But why is this research so important? Understanding the physiological health and well-being of bats is paramount for their conservation and for maintaining the delicate balance of the ecosystems they inhabit. Bats play pivotal roles in pollination, pest control, and seed dispersal, underscoring the significance of their well-being to biodiversity.

Be sure to stay tuned for updates as we delve deeper into the mysteries of wild bat monitoring through the lens of science and exploration!
