The islands at the nature reserve are used by colonies of seabirds to breed and raise their chicks.

A new island has been built at a nature reserve to support a colony of seabirds devastated by bird flu.

RSPB Saltholme in Stockton, Teesside, hopes common terns, roseate terns and black-headed gulls will use it as nesting space.

The three species have been placed on a conservation watch list by the British Trust for Ornithology (BTO).
