Work is under way to protect one of the UK's rarest seabirds.
Little terns breed on a shingle beach in north Wales, they return each April from Africa to nest at the Gronant dunes on the Dee estuary but there is a warning the birds are threatened by climate change.
A five-year EU partnership aims to make sure the bird has a long-term recovery in Wales.
Beach visitors, in particular, are being urged to give the birds space.
The RSPB says other UK little tern colonies - on the Tees and in Lincolnshire - have already been lost because of changes to the UK coastline, and predictions of increased coastal flooding and sea level rises could spell further disaster for these elegant tiny seabirds.
Colin Wells, site manager for the RSPB on the Dee Estuary Reserve has helped erect and maintain a predator exclusion fence, and monitor breeding numbers at Gronant.
