Using fake nests to save rare bird from dying out
Researchers made fake nests and filled them with chicken eggs to lure predators away from killing a rare bird.
There are believed to be about 500 capercaillie left in the UK, all of them in a few upland areas of Scotland.
They are a ground-nesting species and pine martens and badgers are among predators that eat their eggs and chicks.
University of Aberdeen said the artificial nests and also leaving out deer meat had increased capercaillie nest survival by 83% at a trial site in the Cairngorms.
The research has been published in British Ecological Society’s Journal of Applied Ecology.
The University of Aberdeen's School of Biological Sciences said the study suggested diversionary feeding could be a significant contributor to saving capercaillie from extinction.
As a result of the research, it is being rolled out by Forestry and Land Scotland, RSPB Scotland and other organisations in Deeside in Aberdeenshire.
The eight-week trial during the latest breeding season was carried out in a 23 sq mile (60 sq km) area of land managed by Cairngorms Connect Partnership.
Capercaillie and pine marten are both protected species.
PhD researcher Jack Bamber said: “A major obstacle in effective conservation management is the conflict between recovering predators eating endangered prey.
"This challenge is becoming commonplace in the era of ecosystem restoration.
"In Scotland, the much-celebrated recovery of the pine marten, a nest predator, and the conservation of one of its potential prey, the capercaillie, epitomises this issue."
Mr Bamber said diversionary feeding was a potential solution to this conflict.
He added: “Our idea was to fill the bellies of pine martens and other predators, like badgers, in capercaillie strongholds, predicting that once full of free food they would no longer search for eggs.”
In 2022, scientists warned capercaillie could be wiped out in Scotland within the next 30 years.
Numbers of the large grouse have declined markedly since the 1970s.
In continental Europe, the birds' conservation status is not rated as a concern but they are considered to be an endangered species in Scotland.
Most capercaillie are found in the Cairngorms National Park.
