Derelict Second World War pillboxes at RSPB Loch of Strathbeg are being given a new lease of life as nesting sites for the in-decline Common Tern, thanks to an innovative conservation project.
Through the conservation programme Species on the Edge, four disused military structures are being converted into safe breeding habitats for the threatened seabirds at the reserve, located on Scotland's north-east coast.
The pillboxes were originally built in 1940 as part of an anti-tank stop line to protect the flat beaches from potential invasion and to defend the nearby airbase. Now, 85 years later, they are being transformed to help safeguard wildlife.
Species on the Edge Trainee Luke Butler has been leading the conversion work, covering the pillbox roofs with shingle substrate and installing mesh fencing on wooden frames to protect against predators. The design mimics the natural gravel and shingle sites where Common Terns typically build their simple nests.
Luke Butler said: "It's great to be transforming these relics of wartime defence into sanctuaries that could bring new life to the reserve and help create a securer future for Common Terns in Scotland."
Common Terns are facing numerous threats including declining food availability, human disturbance, predation, and the effects of avian influenza, but habitat loss has been particularly damaging.
The pillbox project aims to bolster the existing Common Tern population at RSPB Loch of Strathbeg – the UK's largest dune loch – by increasing the availability of breeding habitat. This will give the terns more options for safe nesting sites, free from disturbance and predation.
