Two groups set off round the coast from St Mary's on the first day, one going clockwise and the other widdershins. Both groups completed circuits of the island on the second day.
Camilla had the good fortune to spot a wryneck. She thought it might be a wheatear and was looking through her binoculars to decide when a keen birdwatcher approached and profusely thanked her for finding a wryneck as he had been looking out for one all week! The photo below was actually taken on Tresco.
