Barn Owl
A quiet presence with a powerful impact – the barn owls nesting in the UFS Sasol Library have become unexpected ambassadors for conservation, inspiring hands-on research, community care, and a deeper connection between people and nature.

High above the shelves and silent study spaces of the Sasol Library at the University of the Free State (UFS), a quiet conservation success story is unfolding. A pair of barn owls have been nesting in the library’s roof space – raising chicks, hunting on campus grounds, and becoming an unexpected symbol of ecological balance and cross-departmental collaboration.

More than just a charming tale of urban wildlife, their presence is also prompting reflection on the evolving purpose of academic spaces.

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, whose portfolio includes libraries, sees the owls as part of something much deeper. “If we consider Shakespeare’s play, All’s Well That Ends Well, then the presence of the owls in the Sasol Library confirms another meaning of that play.”

“Love,” Prof Reddy says, “is not always considered noble, but is something persistent, and our library is not just a building, but a living ecosystem where precious documents, people, and even animals can interact, shape, and nurture our lives.”

The owls had been observed roosting at the library since 2016, but their fate took a turn in 2023 when a distressed owl was spotted outside the building. Tanya Scherman from the Centre for Teaching and Learning was the first to respond. “It appeared that the owl had been poisoned, most likely secondary poisoning from a contaminated rodent,” she explains. That moment became the catalyst for a grassroots conservation initiative – one that brought together concerned staff, students, and wildlife researchers.

“I phoned around trying to find more knowledgeable people who could help,” says Scherman. “I consulted with a local vet, the Owl Rescue Centre in Pretoria, and Prof Francois Deacon from our Faculty of Natural and Agricultural Sciences. I wanted to know how we could keep the owls safe on campus.”

Prof Deacon, who lectures in the Department of Animal Sciences, immediately saw the potential. “As someone passionate about urban wildlife conservation, I saw a great opportunity – not just to support the owls, but to involve students in hands-on learning,” he says. “These projects offer rare chances to study natural animal behaviour in real time, outside the confines of a lab.”

Together with his postgraduate students, Ruan Higgs and Kaitlyn Taylor, the team assessed the owls’ behaviour and advised on the design of a suitable nesting structure. They also installed a motion-triggered, infrared field camera to monitor the owls’ activity safely and without disruption.

But first, the nesting box had to be built. That part of the project became unexpectedly personal. “I worked with my dad to build it,” says Scherman. “He’s an avid animal lover too, and we spent a weekend sawing, sanding, and assembling the box using a blueprint we found online.” With the help of Prof Deacon’s team, the completed structure was carried up into the roof space and secured on a ledge that the owls already favoured. “It was such a special moment to share with my family,” she adds.

 

A window into wildlife on campus

Scherman and Prof Deacon’s efforts have already yielded encouraging results. In 2023, a breeding pair successfully raised two owlets. “This year we found six eggs,” Scherman shares. “Of those, we are currently able to see three owlets.”

For Prof Deacon and his students, the camera has opened a window into the birds’ world. “It captures feeding events, chick development, and parental behaviour,” he explains. “This kind of passive monitoring is invaluable – it provides long-term data without human interference.” The footage has already formed the basis of student research into owl diet, chick growth, and even nesting material preferences – insights that could guide future conservation projects both at the UFS and beyond.

“These owls are teaching tools,” he says. “They bring textbooks to life for students studying ecology, animal behaviour, and sustainable land use.” He adds that the project also demonstrates how scientific knowledge can directly benefit local ecosystems. “It shows that biodiversity and human development can coexist with the right approach. Even a university library can become a habitat.”

Barn owls also play a practical ecological role on campus. “A single owl pair can eat hundreds of rodents in a breeding season, reducing the need for poisons and pesticides,” says Prof Deacon. And it’s not just rodents. “We found remains of small birds and insects in their regurgitated pellets,” Scherman notes, “which shows just how active and adaptive they are in an urban environment.”

Still, their survival is not guaranteed. Urban owls face risks ranging from road traffic to poisoning. “If you ever find an injured owl or have concerns, don’t try to help it yourself,” Scherman advises. “Rather contact Prof Deacon or me. We’re here to assist.”

“Awareness builds respect,” Prof Deacon adds. “When people know that these owls are quietly raising a family above their heads, it shifts how they interact with the space. We ask people to avoid making loud noises or using flash photography near the nesting site. Simple behaviours, such as keeping windows closed at night near the roost, go a long way towards protecting them.”

 

A library as a living ecosystem

As the project gained momentum, so did its symbolic weight across campus. Prof Reddy reflects on how a seemingly disruptive moment became something much more valuable:

“It is clear that what may be seen as a disruptive incident with an owl swooping into our library space is also a pedagogical and deeply conservation touchdown.”

For Prof Reddy “it inspires us to bring science and the love of books to become a teachable opportunity. If libraries are stereotypically perceived to be the quiet corner of academia, then our barn owl event tells us that our library is also a space where silence meets storytelling. The barn owls sparked a conversation about nature, knowledge, and care. It tells us that our library has become an ecosystem of compassion, where not simply books and knowledge matter, but where every creature’s story has a rightful place. This event has mobilised so many different parts of both the university and external communities. We are greatly inspired”.

 

Changing perceptions, protecting heritage

The project also touched on a deeper cultural significance. Owls are often misunderstood, linked to myths or fear in some communities. “It’s understandable,” Scherman says, “with their eerie calls, white faces, and ghost-like flight. But they are also messengers, protectors, and symbols of wisdom in many traditions.”

She believes education is key to changing these perceptions: “Let us embrace the opportunity to coexist respectfully with nature and wildlife. The presence of owls among us is a living testament to the rich biodiversity that thrives even in urban spaces.”

For Scherman, the project was far more than a conservation effort. It was a passion project rooted in her own family history. “My grandparents also had a special connection to owls, so this felt very close to home,” she says. “Observing their habits and individuality made me feel like their caretaker. When we saw the baby owlets, I naturally felt like I was being promoted to an owl-granny!”

Prof Deacon reflects on how the project has enriched campus relationships. “What’s been most rewarding was how many people came together around this – from librarians to students to scientists. We built friendships, not just a nest box.” He adds that librarian Hesma van Tonder even joined one of their giraffe capture excursions. “That kind of connection – between research and real-life adventure – is what makes conservation come alive.”

Looking ahead, he hopes that this project will inspire more cross-campus initiatives. “We’re exploring green corridors, rooftop biodiversity zones, and opportunities to conserve other species such as bats and pollinators,” he says. “It’s only the beginning. Hopefully, other departments such as Zoology and Botany can also come on board in the future.”

 

A space for stories – and for nature

As the owls continue to thrive above the Sasol Library’s quiet corners, their presence invites the university to see its own spaces differently – as places where knowledge, nature, and compassion can coexist.

Prof Reddy reflects on this shared journey:

“The owls invited themselves because they were disoriented and distressed. As a caring university, we demonstrate through our tangible actions that their arrival further ignites our curiosity as a university with a heart. In this way, our library shows how we connect to the world by sheltering not just precious books and knowledge, but that we are an important ecosystem of empathy. Our aspirations for research excellence and impact gains new ground as a vehicle for innovation, equity, and community. My heartfelt appreciation goes out to all our colleagues who are working tirelessly on their thoughtful and dedicated interventions.”

And in closing, he offers a final reflection on what this small but meaningful story reveals about the university’s future:

“If our university matters and is to remain meaningful, our accidental visitors have given new impetus to the fact that our library space holds our stories, and they are making places for new ones as part of our responsible societal futures.”

Eye tracker device a first in Africa
2013-07-31

Keeping an eye on empowerment

"If we can see what you see, we can think what you think."

Eye-tracking used to be one of those fabulous science-fiction inventions, along with Superman-like bionic ability. Could you really use the movement of your eyes to read people's minds? Or drive your car? Or transfix your enemy with a laser-beam?

Well, actually, yes, you can (apart, perhaps, from the laser beam… ). An eye tracker is not something from science fiction; it actually exists, and is widely used around the world for a number of purposes.

Simply put, an eye tracker is a device for measuring eye positions and eye movement. Its most obvious use is in marketing, to find out what people are looking at (when they see an advertisement, for instance, or when they are wandering along a supermarket aisle). The eye tracker measures where people look first, what attracts their attention, and what they look at the longest. It is used extensively in developed countries to predict consumer behaviour, based on what – literally – catches the eye.

On a more serious level, psychologists, therapists and educators can also use this device for a number of applications, such as analysis and education. And – most excitingly – eye tracking can be used by disabled people to use a computer and thereby operate a number of devices and machines. Impaired or disabled people can use eye tracking to get a whole new lease on life.

In South Africa and other developing countries, however, eye tracking is not widely used. Even though off-the-shelf webcams and open-source software can be obtained extremely cheaply, they are complex to use and the quality cannot be guaranteed. Specialist high-quality eye-tracking devices have to be imported, and they are extremely expensive – or rather – they used to be. Not anymore.

The Department of Computer Science and Informatics (CSI) at the University of the Free State has succeeded in developing a high-quality eye tracker at a fraction of the cost of the imported devices. Along with the hardware, the department has also developed specialised software for a number of applications. These would be useful for graphic designers, marketers, analysts, cognitive psychologists, language specialists, ophthalmologists, radiographers, occupational and speech therapists, and people with disabilities. In the not-too-distant future, even fleet owners and drivers would be able to use this technology.

"The research team at CSI has many years of eye-tracking experience," says team leader Prof Pieter Blignaut, "both with the technical aspect as well as the practical aspect. We also provide a multi-dimensional service to clients that includes the equipment, training and support. We even provide feedback to users.

"We have a basic desktop model available that can be used for research, and can be adapted so that people can interact with a computer. It will be possible in future to design a device that would be able to operate a wheelchair. We are working on a model incorporated into a pair of glasses which will provide gaze analysis for people in their natural surroundings, for instance when driving a vehicle.

"Up till now, the imported models have been too expensive," he continues. "But with our system, the technology is now within reach for anyone who needs it. This could lead to economic expansion and job creation."

The University of the Free State is the first manufacturer of eye-tracking devices in Africa, and Blignaut hopes that the project will contribute to nation-building and empowerment.

"The biggest advantage is that we now have a local manufacturer providing a quality product with local training and support."

In an eye-tracking device, a tiny infra-red light shines on the eye and causes a reflection which is picked up by a high-resolution camera. Every eye movement causes a change in the reflection, which is then mapped. Infra-red light is not harmful to the eye and is not even noticed. Eye movement is then completely natural.

Based on eye movements, a researcher can study cognitive patterns, driver behaviour, attention spans, even thinking patterns. A disabled person could use their eye-movements to interact with a computer, with future technology (still in development) that would enable that computer to control a wheelchair or operate machinery.

The UFS recently initiated the foundation of an eye-tracking interest group for South Africa (ETSA) and sponsor a biennial-eye tracking conference. Their website can be found at www.eyetrackingsa.co.za.

“Eye tracking is an amazing tool for empowerment and development in Africa, “ says Blignaut, “but it is not used as much as it should be, because it is seen as too expensive. We are trying to bring this technology within the reach of anyone and everyone who needs it.”
