The gull colony, one of the few kittiwake breeding sites in the South, has fared relatively well, despite seabirds struggling
elsewhere.
In July, the RSPB warned of a potential seabird crisis as reports filtered through of abandoned nests and empty cliffs in parts of Scotland and Wales where internationally-important populations of guillemots, kittiwakes and other seabirds normally breed.
Kate Whitton, Aren't birds brilliant! officer, said, "The Seaford kittiwakes are doing relatively well but this is not the case elsewhere so the need to protect important marine sites has never been greater.
"We are currently campaigning to get the sea between Brighton and Newhaven protected along with other coastal and offshore sites. A draft marine bill exists but we are lobbying for it to be strengthened and turned into UK law as quickly as possible."
Miss Whitton called on all Sussex residents to get involved in the RSPB's Safeguard Our Sealife campaign, or lobby their local MP to protect vital offshore sites on which kittiwakes and other seabirds depend.
Once the Seaford colony is ready, groups will begin their journey across the Atlantic. Many of the juveniles are expected to reach as far as the North American coast, and some young birds may remain in the western Atlantic for several years before returning to Seaford to breed. Adults of the colony will begin to return to the Sussex site next spring.
The RSPB will be down at Splash Point until August 10, showing people these incredible gulls as they get ready for their journey.
The tail end of this story comes as the Wildlife Trust's National Marine Week, supported by BBC Breathing Places, begins (August 2-17) – another reason to make the journey to Seaford and get acquainted with Sussex's sealife.
The RSPB's Aren't birds brilliant! team will be at the eastern end of Seaford Promenade until August 10 from 10am to 5pm daily.
