Two young hen harrier chicks have been satellite tagged at an MoD nuclear base as part of a national project to protect and conserve these threatened birds of prey.
The pair came from a nest of four young located at HM Naval Base Clyde’s high security Coulport site, which is the storage and loading facility for the UK’s Trident nuclear warheads.
All four chicks at the base on Loch Long were ringed and two, a male and a female, were tagged.
Sgt John Simpson, MoD Police wildlife crime officer, said: “The security at HM Naval Base Clyde that protects the Submarine Service also provides a sanctuary for hen harriers, the most endangered bird of prey in the UK.
“We understand that hen harriers are a necessary part of a healthy functioning countryside and are pleased we can play some part in helping to protect them.”
The satellite tagging was conducted as part of the RSPB’s part EU-funded Hen Harrier LIFE+ Project, a five-year programme of nest protection, monitoring, community engagement and investigations work to secure a future for these birds in Scotland and northern England.
Data gathered from the tags will be monitored, to see where the birds go and identify the areas where they are most at risk.
Hen harriers are a red-listed bird species of highest conservation concern in the UK.
These raptors were hunted to extinction over most of the UK during the Victorian era and although their populations have recovered since then, they remain very much at risk from disturbance and illegal killing.
Blánaid Denman, manager of the RSPB’s Hen Harrier LIFE+ Project, said: “The last national survey in 2010 found Scottish hen harrier populations had fallen by 20% in just six years, with only 505 pairs remaining.
“According to an independent government report, Scotland should be able to support up to 1,790 pairs of harriers, but they are still being blighted by illegal killing and disturbance.
“As a result, these iconic birds are now missing from huge swathes of our landscape, when they should be an integral part of Scotland’s natural beauty.
“That’s why this type of work is so important, and why it’s so positive to see a large landowner like the MoD leading by example and championing these birds.
“We’re delighted to have worked alongside the MoD who have been monitoring and protecting this nest at Coulport.
“Given the parlous state of hen harriers in Scotland it’s fantastic to see an adult pair being able to safely raise four fit and healthy young chicks.”
