The Holy Island of Lindisfarne is probably best known for its medieval religious heritage and in the summer months pilgrims from all walks of life flock to the island and swell its community of 160 to over 650,000. But in the winter it's the birds that flock here, taking refuge on this holy land during their winter migration. Helen Mark arrives on Holy Island just as the birds do and learns about their unique relationship with this island.

Bird Historian, Ian Kerr has been visiting the island for more than 30 years and knows of 318 species that have been recorded. He also knows the long and complex relationship the birds have with this landscape and the generations of islanders. Legend has it that St Cuthbert laid down rules for the protection of nesting Eiders, making him Britain's first conservationists - whilst in later centuries, islanders recruited Goldcrests to clear their cottages of spiders and flies.

Laura Scott is a ranger at the Lindisfarne National Nature Reserve which annually welcomes over half the world's population of pale bellied Brent Geese. They are attracted to the mudflats and the special grasses that grow there. Whilst the birds come for the special habitats that the island provides, they bring with them many gifts. For Rev David Peel, a United Reformed Church Minister and long-time birder, they are a reflection of God's beauty and design, offering moments of transcendence. For award winning Northumberland based writer Ann Cleeves, author of ITV's Drama Series 'Vera' and BBC's 'Shetland' series, the birds are an integral part of building a landscape and creating an atmosphere and Holy Island - a place that she first visited with her retired RSPB warden and keen birder husband Tim - is full of this rich bird life and atmosphere.
