Territorial Conflict Claims Life of Reintroduced Golden Eagle Percy in the Scottish Borders
6/16/2026, 11:49:06 AM
Background & Context
The South of Scotland Golden Eagle Project, led by the charity Restoring Upland Nature (RUN), aims to reverse historic declines by translocating juvenile eagles from the Isle of Lewis to the Scottish Borders. Launched in 2023, released birds receive individual names; the four-year-old male was called ‘Percy’ by the Duke of Northumberland. RUN notes that the same breeding pair has been linked to three lethal territorial encounters with released sub-adults.
Timeline
2023 – Percy is released in the Scottish Borders.
28 Mar 2026 – Satellite telemetry records his approach to an active nest and a rapid chase.
1 Apr 2026 – Gamekeepers find the injured bird and alert RUN.
Early Apr 2026 – SRUC post-mortem confirms fatal injuries from an eagle attack.
Data & Statistics
Percy was a four-year-old male; SRUC’s post-mortem identified severe penetrating trauma and a catastrophic skull fracture, injuries described as “typical of an eagle attack.” Satellite tags showed his flight intersecting an active nest on 28 Mar 2026, triggering the fatal chase. The project now monitors over 50 golden eagles in southern Scotland, the highest regional count in roughly 300 years. A breeding pair’s territory can exceed 150 km².
Official Statements & Responses
Dr. Cat Barlow, chief executive of RUN, expressed deep sadness over Percy’s death and explained that territorial aggression toward intruding sub-adults is a natural behavior in wild golden eagles. Ross Ewing, director of Scottish Land and Estates, praised the gamekeepers’ rapid response and highlighted their role in proactive moorland management. Mark Ewart, regional co-ordinator of the Southern Uplands Moorland Group, reaffirmed the sector’s commitment to preserving Scotland’s landscape and moorland habitats.
Verbatim Quotes
- “In natural golden eagle populations, territorial breeding eagles will attack and kill intruding sub-adults.” — Dr. Cat Barlow, RUN chief executive
- “We’re so grateful to SRUC, and to the gamekeepers who did what they could as soon as they found Percy injured.” — Dr. Cat Barlow, RUN chief executive
- “It is incredibly sad that on this occasion it was not possible to save Percy, but the response exemplifies their commitment to proactive moorland management and preserving vital habitats for local wildlife, including golden eagles,” — Ross Ewing, Scottish Land and Estates director
- “We remain committed to preserving Scotland’s landscape and important moorland habitats for generations to come.” — Mark Ewart, Southern Uplands Moorland Group co-ordinator
Why It Matters / Impact
The incident illustrates the inherent risks of reintroducing apex predators into territories already occupied by established breeding pairs, highlighting that natural territorial mortality is an expected component of population recovery. It also underscores the collaborative role of gamekeepers and conservationists in rapid response, and the broader success of the project, now supporting over 50 eagles in southern Scotland.
