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.”

A summary of an inaugural lecture delivered by Prof Robert Bragg at the University of the Free State:

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
