Ards and North Down Council has formed a partnership with the National Trust to protect Arctic Terns nesting on Cockle Island off the coast of Groomsport in County Down.

The initiative includes constructing a floating raft to offer a safer elevated space for the birds to lay eggs. The island hosts several hundred pairs of Arctic and Common Terns.

Council support involves providing a mooring near the island, secure off-season storage, help with annual launching and recovery of the raft, and routine safety checks.

Numbers of the birds have declined in recent years due to rising sea levels, tidal surges from storms, and ecological pressures including bird flu losses in 2023.

At the council's Environment Committee meeting, Councillor Joe Boyle described the project as a way to show commitment to biodiversity.

Councillor Alistair Cathcart noted that North Down MLA Peter Martin and Councillor James Cochrane worked with the Discover Group, the National Trust, and local conservationist Anthony McGeehan on the issue. He highlighted the birds' global migrations and threats from predators such as rats, otters, and seagulls.

Cathcart referenced a recent count of 250 Arctic Terns and stressed the need for monitoring beyond tides to address other predators.

Alliance Councillor Alex Harbinson requested a post-nesting season report on the raft's performance. He mentioned engagement by Councillors John Hennessy and former Councillor Hannah Irwin.
