Two roseate tern chicks hatch following conservation efforts at a coastal nature reserve.

"The numbers follow an improving year-on-year trend," says Durham Wildlife Trust's warden.

Both birds were spotted near or on an island off the Northumberland coast.

The RSPB partners with a hedgehog charity to protect little terns at Chesil Beach from predators.

Old and new conservation methods help improve the birds' success rate, the National Trust says.

RSPB Hodbarrow has completed work on a new island and extra fencing to keep the birds safe.

The show follows staff at Norfolk's Blakeney Point, which is famous for its seal and bird colonies.

Bird flu is devastating several sea bird species along the UK coastline.
