In pictures: Iolo Williams takes on Skomer Island
Iolo Williams on Skomer Island
Iolo's already been under the waves to explore one of only three British marine nature reserves.
Filming the dive
He'll be exploring the lives of the largest colony of Manx shearwater in the world, a third of the entire world population of the species, as they get together to breed. And he'll get up close and personal with the latest arrivals to the island as new hatchlings take centre stage. Look out for razorbills, guillemots and puffins.
Iolo and the team are out filming at all times of day and night and in all weather conditions as they take on the wilds of this beautiful Welsh island.
Out at sea and in low lighting, the team are still filming
Watch Iolo report live from Skomer next week (6-9 June) on Springwatch.
