Golden eagle numbers close to ‘historic’ levels

Numbers of golden eagles in Scotland are close to “historic” levels, with more than 500 pairs, a survey of the birds has found.

RSPB Scotland said there had been a 15% rise since 2003, when the last survey took place, from 442 to 508 pairs.

The research was carried out by experts from the wildlife charity and the Scottish Raptor Study Group.

Scotland is now thought to be home to the UK’s entire population of golden eagles.

England’s only resident golden eagle, which occupied a site near Haweswater in the Lake District, has not been seen for more than a year and is feared dead.

The RSPB said the six-month survey – which the charity co-funded with Scottish Natural Heritage (SNH) – showed the raptor could now be defined as having a “favourable conservation status”.

‘Awe-inspiring’

Numbers of golden eagles in Scotland reached very low numbers in the mid-19th Century, but have been steadily recovering since then.

Duncan Orr-Ewing, head of species and land management at RSPB Scotland, said the birds were an “awe-inspiring part of our natural heritage” and welcomed the news from the survey.

“Across many parts of Scotland there’s been a very welcome turnaround in how people respect these magnificent birds, part of a more enlightened public attitude towards birds of prey,” he said.

“Increased monitoring and satellite tagging of eagles, as well as stronger sanctions against wildlife crime may be serving as effective deterrents against illegal activity, therefore helping their population to increase.

“However, the continued absence of golden eagles in some areas of eastern Scotland remains a real cause for concern and suggests that much more work needs to be done.”

The northern Highlands and the area between the Great Glen and Stirling saw the greatest increase in numbers between 2003 and 2015, when this latest survey was carried out.

Recovery also continues in much of the west Highlands and islands.

However, the population west of Inverness remained stable over the past 13 years rather than grew.

The RSPB said the reason behind the lack of recovery in that area was not clear, but pointed to persecution, recreation, forestry and poor weather as possible factors.

A decline in the number of animals that eagles eat because of grazing pressure from deer is thought to be another possible cause.

The survey also found golden eagles were not found at all in many parts of the eastern Highlands, with less than a third of these traditional “home ranges” occupied by a pair, despite being a “very productive landscapes” for these birds.

The RSPB blamed the raptor’s absence from these areas on persecution and said four eagles fitted with satellite tags had been found illegally killed in the central and eastern Highlands between 2009 and 2013.

And in August, it emerged that eight golden eagles had vanished in the Monadhliath mountains, south-east of Inverness, in less than five years.
