MORE than 500 tonnes of aggregate has been delivered by boat to replenish a vulnerable beach that is home to a rare bird.
The shingle has been deposited on South Binness Island in Langstone Harbour.
The small island is a refuge for the Little Tern.
In recent years eggs or chicks have been washed away by the tide, but it is hoped the raised beach will allow bird colonies to flourish.
Replenishing the beach marks the first phase of a three-year project by the RSPB, which was awarded £74,200 from the Heritage Lottery Fund.
Wez Smith, RSPB Langstone Harbour site manager, said: ‘Sea level rise will be a real problem for little terns in years to come and protecting the significant Langstone Harbour population will make a massive contribution to sustaining their nationally declining population.’
The aggregate was provided by Lafarge Tarmac.
