Vintage Inns, the Six Continents Retail-owned pub-restaurant chain, has collected two tonnes of used wine corks to give to a project organised by the RSPB.

The initiative aimed to raise awareness of the decline of the Portuguese cork orchards and the subsequent effect on indigenous bird populations, in particular the country's eagles.

The cork, which was collected over 12 weeks, went towards a sculpture of a twelve-foot eagle by artist Robert Bradford. It works out at approximately 22lb of corks from every one of the 200 or so Vintage Inns outlets

The eagle will be put on permanent display at the Eden Project in Cornwall.
