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.”

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
