AI tool created to monitor barn owl chicks without disturbing nesting sites
He is working with biologist-turned-electronics engineer Brian Cresswell to create the computer model which can calculate the number of owls by being able to distinguish their individual calls.
Mr Jayathunge said: 'We're using AI to count baby barn owls by sound instead of disturbing them in their nests with video cameras.
'This helps reduce stress on the birds and could give us data from natural nest sites, which are often inaccessible for monitoring, not just the artificial nest boxes where most of the data we currently have comes from.'
He explained the AI technology would be able to identify distinctions in sounds made by each baby owl which would be indistinguishable to the human ear.
It would pick out the differences in frequency which would indicate the number of birds, as well as each individual bird's identity.
He added: 'Bringing AI and ecology together in such a positive way is a great example of how this technology can be used for good.'
Mr Cresswell, who has helped test the technology on nest boxes in north Dorset, said: 'This basic data is important for monitoring breeding success of barn owls, which can vary greatly between years and breeding sites.
'The AI model is also a great research tool to study the behaviour of young owls and the purpose of their hissing, which is believed to be a means to negotiate who will get fed at the next food delivery by their parents.
'There may also be potential for the hissing analyses to determine how hungry the owlets are, which again is important data for monitoring breeding success.'

Mr Jayathunge said the long-term aim of the project was to develop the technology so volunteers and conservationists would be able to capture the sounds of hissing owlets at their nests.
He explained that barn owl hissing was loud so audio recorders could be placed away from the nests to help abide by strict protocols which protect barn owls and their nests under Schedule One of the Wildlife and Countryside Act.
He added: 'It has great potential for citizen science as it doesn't require expensive and specialist equipment – anyone could gather recordings and send them for analysis.
'By making barn owl nest monitoring more scalable and less invasive, we hope this project can contribute to better long-term outcomes for the species.'

Eating fries over boiled potatoes increases type 2 diabetes risk
Those who consume similar amounts of boiled, baked or mash potatoes do not have an increased risk, researchers found. An international team of researchers, including an expert from the University of Cambridge, wanted to investigate any links between potato consumption and the risk of type 2 diabetes. Academics analysed data on studies tracking the health of more than 205,000 health workers in the US. Repeated surveys about people's diets were performed over almost four decades. And during the study follow-up periods, some 22,000 cases of type 2 diabetes were documented. Overall the research team found that consumption of baked, boiled or mashed potatoes were not linked to an increased risk of type 2 diabetes (T2D). But people who had a higher consumption of French fries – at least three weekly servings – had a 20% increased risk. And those who eat fries five times a week appeared to have a 27% increased risk. 'The risks associated with potato intake varied by cooking method,' the authors wrote in The BMJ. 'The association between higher potato intake and increased T2D risk is primarily driven by intake of French fries. 'Higher intake of French fries, but not combined baked, boiled, or mashed potatoes, was associated with a higher risk of T2D.' The research team also found that replacing three servings of potatoes each week with whole grains was found to lower the risk of type 2 diabetes by 8%. 'Replacing any form of potatoes, particularly French fries, with whole grains is estimated to lower the risk of T2D, reinforcing the importance of promoting whole grains as an essential part of a healthy diet,' they wrote. But replacing potatoes with white rice was associated with an increased risk of type 2 diabetes, they found. The research team also performed a review of all of the other studies on the topic which had similar findings. Researchers found people who eat lots of french fries are at a higher risk of type 2 diabetes (Alamy/PA) In a linked editorial, also published in The BMJ, experts from the US and Denmark wrote: 'This finding also corresponds to the observed associations between high intake of ultra-processed foods and high risk of type 2 diabetes – French fries are often ultra-processed, whereas baked, boiled, or mashed potatoes are often minimally processed.' They added: 'With their relatively low environmental impact and their health impact, potatoes can be part of a healthy and sustainable diet, though whole grains should remain a priority.' Commenting on the study, Dr Faye Riley, research communications lead at Diabetes UK, said: 'This research shows that the link between potatoes and type 2 diabetes isn't as clear-cut as it might seem. 'Type 2 diabetes is a complex condition, with many factors influencing its development, including genetics, age and ethnicity. 'Diet is just one part of the picture, but this study suggests that how food is prepared can make a difference and reinforces the advice to prioritise whole grains and cut back on fried or heavily processed foods as a way to support a balanced diet and reduce your risk.'
