Bird flu has spread to the Isle of St Kilda after a breakout among the Shetland Isles.
The National Trust for Scotland confirmed a 'significant' number of the Great Skua population has died in recent days.
On the charity's count, a total of 104 birds have died from Avian Flu this season.
It reassured members of the public that all relevant protocols will be followed to ensure the safety of staff and visitors to the island.
A statement reads: "We're saddened to report that cases of avian flu have been confirmed on St Kilda, and we have lost a significant proportion of the Great Skua population (104 individual birds so far this season).
"We’re very concerned about the impact this outbreak might have on the archipelago, which is home to one of the most important seabird colonies in Europe.
"We’ll continue to monitor and follow all relevant protocols, ensuring that staff and visitors are safe."
Last month, the Scottish Government confirmed the illness had been identified on Whalsay Island at a commercial premises in Shetland.
Dozens of dead birds had been pictured scattered across nearby Isle of Foula after a Avian Flu outbreak.
Images of Bonxies carcasses in the Shetland Isles were shared by the area's heritage group.
A Scottish Government spokesperson said: “Winter 2021/22 has seen the largest outbreak of avian flu in the UK to date. This has affected the wild bird population as well as commercial flocks.
“While maintaining high levels of biosecurity among domestic flocks helps protect against disease, addressing the disease among wild birds poses significant challenges.
“Avian Influenza is a disease that affects the wild bird population globally.
“The Scottish Government is taking the situation very seriously and is working hard with partner organisations to progress measures to respond to the reports of increased mortality among wild bird populations and help them become more resilient.”
