The Farne Islands, which are run by the National Trust, are situated two to three miles off the Northumberland coastline. The archipeligo of 16-28 separate islands (depending on the tide) make the summer home to approximately 100,000 pairs of breeding seabirds including around 36,000 Puffins, 32,000 Guillemots and 2,000 pairs of Arctic Terns. The species of birds which nest in internationally important numbers include Shag, Sandwich Tern and Arctic Tern. The coastline around The Farnes are also the breeding ground to one of Europe's largest Grey Seal colonies with around 4,000 adults giving birth to 1500 pups every year.
